[July 20, 1965] No War of the Worlds After All? (Mariner IV reaches Mars)

5 Comments


by Kaye Dee

Just a few days ago, on July 15, NASA’s Mariner IV space probe made history by being the first spacecraft to successfully reach the planet Mars, capturing images of its surface. These are the first close-up views of another planet in our solar system and the initial pictures suggest that, despite what science fiction would have us believe, Earth won’t have to fear an invasion from Mars any time soon!

The first close-up image ever taken of Mars, showing the limb of the planet and a haze-like feature that might be clouds. The smallest features in this image are roughly 3 miles across, but there's no sign of Martian canals!

The Canals of Mars

Mars has been an object of intense scientific and popular fascination since the last century, when telescope observations first suggested that the planet was potentially Earthlike, since it showed polar caps and surface changes that appeared to represent seasonal variations due to the growth and die-back of vegetation. Then, in 1877, the Italian astronomer Schiaparelli observed what he called “canali” on Mars. He apparently meant grooves or channels on the Martian surface, but his work was translated into English as “canals” and some astronomers took this literally to mean that he had observed structures that were the work of intelligent beings.

A section of one of Percival Lowell’s maps of Mars, published in his 1895 book Mars. The complete map depicted 184 named canals marked on it using numbers.

By the end of the 19th Century, the idea that there is intelligent life on Mars had taken hold, thanks particularly to the writings of American astronomer Percival Lowell (the same Percival Lowell who is also associated with the discovery of the Planet Pluto!) He believed in a Martian civilisation that had constructed vast networks of canals to bring water from the planet’s poles and wrote several books and innumerable newspaper articles detailing his observations of canal systems on the Red Planet. Science fiction stories like H.G. Well’s War of the Worlds, first published in 1897, and Edgar Rice Burroughs' "Barsoom" series further encouraged popular belief that there was intelligent life on Mars and generated something of a ‘Mars mania’ that has grown across the 20th Century.

Cover of the August 1927 issue of Amazing depicting the iconic Martian machines from Wells' War of the Worlds. This powerful story has been re-interpreted on radio and film and has had a tremendous influence in shaping popular perceptions of life on Mars.

The Mars Race

Most scientists have accepted for a decade or more now that modern telescope observations indicate that it is unlikely that higher forms of life will be found on Mars after all. Yet the fascination with Mars has been so strong that it’s not surprising the planet became an early target for space exploration, after the Moon. The Soviet Union started the race to Mars in October 1960, with “Marsnik” 1 and 2. We don’t know much about these probes, but it seems they both failed even to reach orbit. The USSR’s Mars 1 flew past Mars in June 1963, but it had stopped sending back data in March. Sputnik 22 and Sputnik 24, both launched around the same time as Mars 1, are also believed to be elements of a failed Mars mission. Zond 2, launched just 2 days after Mariner IV, is also assumed to be an attempted Mars mission, though it, too, ceased transmitting en route. Clearly, getting to Mars is hard. Mariner IV was meant to be a twin mission with Mariner III, but that mission also failed at launch.

Even though Mars 1 ceased transmitting long before it reached Mars, the USSR still celebrated it as an achievement on its 1964 Cosmonauts Day stamp.

Mariner IV was launched on an Atlas Agena rocket from Cape Canaveral at 12:22 GMT on November 28, last year. It has an octagonal magnesium frame, 50 inches across the diagonal and 18 inches high, which houses the electronic equipment, propulsion system and attitude control gas supplies and regulators. Four solar panels, containing a total of 28,224 solar cells, are attached to the top of the frame. They are able to generate 310 watts of power at the distance of Mars from the Sun. Mariner also has two antennae for transmitting data back to Earth: An elliptical high-gain parabolic antenna and an omnidirectional low-gain antenna, mounted on a seven-foot, four-inch-tall mast next to the high-gain antenna.

Mariner IV is an incredibly sophisticated space probe for its size, packed with scientific instruments, plus its television camera system. Its design is a radical departure from the conical design used for the Ranger Moon probes and NASA's successful Mariner II mission to Venus.

Deep Space Laboratory

For its relatively small size, Mariner IV is a spacegoing scientific laboratory, designed to measure the conditions in deep space between Mars and the Earth and in the vicinity of Mars itself. Its scientific instruments include a helium magnetometer to measure the characteristics of the interplanetary and planetary magnetic fields; an ionization chamber/Geiger counter, to measure the charged-particle intensity and distribution in interplanetary space and in the vicinity of Mars; a cosmic ray telescope, to measure the direction and energy spectrum of protons and alpha particles; a solar plasma probe, to measure the very low energy charged particle flux from the Sun, and a cosmic dust detector, to measure the momentum, distribution, density, and direction of cosmic dust. Although the Geiger counter failed in February and the plasma probe's performance is degraded, the other instruments are all working well.

Mariner IV's 'endless loop' magnetic tape recorder. Its 330ft of tape has a storage capacity of 5.24 million bits – right at the cutting-edge of recording technology!

Probably the most important instrument on Mariner IV, and certainly the one of the most interest to the public, is its television camera, designed to obtain close-up images of the Martian surface. The camera is mounted on a scan platform at the bottom centre of the spacecraft and consists of 4 parts: a Cassegrain telescope with a 1.05° by 1.05° field of view; a shutter and red/green filter assembly with 0.08s and 0.20s exposure times; a slow scan vidicon tube which translates the optical image into an electrical video signal, and the electronic systems required to convert the analogue signal into a digital signal for transmission. During the fly-by of Mars, all the television images and the data gathered by the scientific instruments were stored on an ‘endless loop’ four-track magnetic tape recorder for later transmission back to Earth. 

First Pictures from Another World

On July 15 Mariner 4 passed within 6117 miles of Mars, spending just 25 minutes doing visual observations of the planet’s surface. During that brief time, its television camera captured 21 full pictures and part of a 22nd, the first ever close-up images of the surface of another planet. Each photo covers an area of about 77 square miles. It takes about 10 hours to transmit each image back to Earth and each picture is being transmitted twice to ensure that all the data is correctly received.

The second Mariner IV image released by NASA shows the border of Elysium Planitia and Amazonis Planitia. Taken from around 9,940 miles, the picture is about 310 miles across and 560 miles from top to bottom because the surface is curving away. North is up and the sun is illuminating the area from the southeast.

Only three of the Mariner Mars images have so far been released, but already they have disappointed scientists and the public alike by putting an end to any hope of finding intelligent life on the Red Planet. What they have so far revealed is a world that looks more like the Moon than the Earth, with no signs of water, vegetation or animal life. When this is coupled with the findings of the scientific instruments, which show that Mars has an atmosphere of carbon dioxide with only a very low atmospheric pressure (only a fraction of that found on Earth, which was quite a surprise to scientists), a daytime temperature of -148 degrees F and no magnetic field (meaning that the surface of the planet is bombarded by the solar wind and cosmic radiation), it means that the prospects for any kind of life on Mars are very small indeed. However, Mariner’s images only cover just 1% of the Martian surface, so perhaps we should not entirely give up hope that future missions will find Mars more exciting and scientifically interesting than it seems right now. After all, the pictures have not yet revealed the cause of the apparent seasonal changes observed from Earth….

The third image we have seen so far shows the Orcus Patera region in western Amazonis Planitia. It was taken with the sun only 13 degrees from vertical, so the topography is hard to make out, although some raised areas can be seen at upper left. The image is 202 miles across and 319 miles from top to bottom. The resolution is about 1.9 miles and north is up.

Australia Plays Its Part

Australia has played a crucial role in the Mariner IV mission, with its first images being received at the Tidbinbilla tracking station outside Canberra. NASA’s second Deep Space Network station in Australia, Tidbinbilla became operational in December 1964 so that it could support the Mars mission. As the signal from Mars is very weak, the station asked the civil aviation authorities to divert any aircraft that might interfere with the reception of the signals from Mariner at the time of the fly-by. This resulted in an amusing incident: at the critical time, just when Mariner 4 had gone behind Mars, the direct phone from Canberra Airport rang and the station was asked if it was experiencing interference from a UFO! It now seems that the offending object was a weather balloon and not a Martian saucer come to check on what the Earthmen are up to.


Nestled in a secluded valley, for protection from radio interference from nearby Canberra, NASA's Tidbinbilla Deep Space Network Station received the first images of Mars from Mariner IV. Australia is host to a growing number of NASA tracking stations covering all its space tracking networks.

A Role for a Radio Telescope

Australia’s Parkes radio telescope, the largest fully steerable radio telescope in the world, also played a role in receiving Mariner IV’s Mars images. NASA is basing the design of its new 210 ft antennae for the Deep Space Network on that of the Parkes telescope. As a demonstration of its tracking capabilities, Parkes has also tracked Mariner IV and received some of its images from Mars. Its greater antenna size, and therefore better reception capabilities, mean that its images will be more detailed than those received by the 85 ft dishes at Tidnbinbilla and other NASA stations and they will enhance the overall quality of Mariner IV’s Mars pictures when the Parkes and Tidbinbilla images are combined. I hope that NASA will release the rest of the Mariner images soon: even if they have dashed almost a century of Martian fantasies, they are revealing a planet that is very different from what we have expected and I wonder what further surprises might be in store for us as we explore more of Mars and the rest of the Solar System….

The world-leading radio telescope developed by the Commonwealth Scientific and Industrial Research Organisation, Australia's national civil scientific research body. Located near Parkes, New South Wales, this astronomical instrument is also proving its value as a space tracking facility and I'm sure that NASA will call on it again in the future for further tracking support

[June 22, 1965] Standby for Action! (Gerry Anderson’s Stingray)

5 Comments


by Kaye Dee

“Standby for Action!” is the dramatic opening line of the opening titles for Gerry and Sylvia Anderson’s most recent marionette science fiction series, Stingray, which then go on to promise us “Anything can happen in the next half hour!” And with over 39 episodes of undersea adventure Stingray lives up to that promise.


World Aquanuat Security Patrol Commander Shore warns us that “Anything can happen in the next half hour” in the Stingray opening titles. Note the caption “in Videcolor” in the background, telling even viewers watching in in black and white that the show is made in colour

Stingray completed its first Australian screening run a few weeks ago on June 9, having commenced on the national broadcaster, the Australian Broadcasting Commission (ABC), on September 16, 1964. As I’ve recently discovered from my friend at the ABC, this was, unusually, three weeks before the show commenced screening in Britain: as you might recall from my article about the long-delayed arrival of Doctor Who in Australia, we are more likely to be months, if not years, behind in screening television series from overseas. In fact, the Andersons’ earlier series, Fireball XL5, still hasn’t arrived on our shores, but I’ve heard that it will be shown on one of the commercial television channels later in the year.


The Stingray, series title. I’ve read that Gerry Anderson said an undersea show was the next logical step after the land and space exploits of his earlier series Supercar and Fireball XL5

Although I haven’t yet seen Fireball XL5, I discovered Stingray alongside the Andersons’ first Supermarionation puppet creation Supercar, which has been repeated this year on the ABC after first screening in 1963. While Supercar is good kiddie fun (thanks to my niece and nephew for introducing me to both these shows), Stingray shows an order of magnitude of improvement, technically and in the imaginativeness of its storyline.


Stingray, the most advanced submarine of 2065 and titular star of the show

Stingray is a science fiction undersea adventure series, set in the twenty first century (in 2065, as one episode informs us), following the exploits of the crew of Stingray, the most advanced submarine in the World Aquanaut Security Patrol (better known as WASP), one of the armed services of the World Government, charged with policing and protecting civil activities on and under the world’s oceans. However, in Stingray’s world, there are many peoples and civilisations under the sea and, although they have been largely unknown to the surface world previously, many of them have become angered by the “terrainean” exploitation of the resources of the oceans.


The Stingray crew, Troy Tempest, Phones and Marina, the mysterious woman from the sea.

In the first episode, the crew of Stingray, Captain Troy Tempest and his navigator/hydrophone operator, nicknamed “Phones” (apparently his full name is given in the promotional material for the series, but it never gets mentioned on screen), are captured by Titan, King of undersea city of Titanica. When his god (represented by a giant fish that looks like a cross between a grouper and a coelacanth!) rejects Troy and Phones, Titan condemns them to death, but they escape, aided by Marina, the mute daughter of the ruler of another undersea kingdom, whom Titan has been keeping as his slave. Marina returns with Troy and Phones to the WASP home-base of Marineville and becomes a member of the Stingray crew, using her knowledge of the undersea world to assist in their missions.


Titan, the evil King of Titanica, the arch-enemy of the Stingray crew, and his minions, the Aquaphibians.

This sets the stage for the series, with Titan and his creepy henchmen X-20 and the Aquaphibians, becoming the WASPs’ main undersea adversaries. While many stories involve battles with, or thwarting plots against, the WASP, or the surface world in general, by Titan and his allies, there is plenty of other action for the Stingray crew as well: we see them involved in exploration, participating in marine archaeology, undertaking rescue missions, investigating piracy and terrorism, assisting undersea peoples, becoming embroiled in international diplomacy and even discovering the truth about the Loch Ness Monster! Of course, being a children’s show, some of the stories are silly, and there are too many ‘dream episodes’, where strange things happen, for my taste – but many have a tongue-in-cheek humour that can be appealing to adults, and others touch on grown-up ideas such as whether or not we should exploit the mineral resources of the ocean floor.


Stingray in its pen under Marineville, awaiting the call to “Action Stations”

Unlike many kids’ adventure shows, the storyline is not completely static but has some developments over time, with Marina being initially somewhat under suspicion as a possible agent of Titan, but gradually becoming accepted, especially by Atlanta Shore, who was romantically involved with Tempest before Marina arrived on the scene. Troy finds himself enthralled by Marina but seems unable to make up his mind between the two women. It must be a first for a children’s television show that it not only portrays a ‘love triangle’ but also makes it the focus of its closing credits, which incorporate the love song “Aqua Marina”.


Atlanta Shore, Troy’s original love interest and her father WASP Commander Sam Shore in Marineville Control. A person with paraplegia in a hovering ‘wheelchair’ as a military commander has to be a role model for disabled children: in the future you can do anything!

I also find it interesting that Stingray includes two handicapped characters among its main cast, both of whom are shown to be vital members of the WASP. Marina may be mute – and episodes deal with her crewmates wanting to help her learn to speak, and the problem of Marineville Control communicating with Marina by radio – but she is intelligent and more than capable of rescuing Troy and Phones on more than one occasion. The Commander of the WASP, Sam Shore, is a paraplegic, who gets around using a hover chair – and an entire episode is devoted to the story of how he was crippled on active duty — but he is in overall charge of the organization. These have to be heartening role models for children afflicted by polio and other disabilities. 


Gerry and Sylvia Anderson and some of the Stingray production team with one of the models of Stingray

Stingray is impressive technically. Those dramatic opening statements at the beginning of the title sequence introduce a series of action shots of Stingray, a lot of explosions, Stingray’s home base Marineville going to red alert (which means the entire base sinking underground and ICBM’s being deployed into launch positions), and an amazing scene of Stingray leaping out of the water, chased by one of Titan’s submarines in the shape of a gigantic mechanical fish. And it’s all accompanied by a staccato, jazzy theme that really works with the visuals.


I’d love to know how they created this dramatic scene of Stingray leaping out of the water, chased by one of Titan’s submarines

The models of futuristic submarines, aircraft and other technology of the twenty first century are beautifully detailed, and the finely crafted miniature sets perfectly match the size of the marionettes, which I understand are about 20 inches tall. I’ve read that the AP Films production team moved into a completely new studio to produce Stingray, which included two sound stages, so that they could shoot two episodes at a time, plus a special stage for filming special effects and huge indoor tanks for filming ocean surface scenes. The ‘underwater’ scenes are apparently shot on a dry set, but filmed through a special fish-filled aquarium in front of the camera, to create a forced perspective of an undersea environment: the kids certainly think it has actually been filmed underwater.


The beautifully detailed model of WASP Headquarters Marineville. The sequences of parts of the base sinking underground during an alert are really impressive

I like the Stingray marionettes, too: they are less caricatured than in Supercar, in fact some of them look like they’ve been modelled on real people. The Troy Tempest puppet reminds me of James Garner, and badguy X-20 looks – and sounds – a lot like Peter Lorre! The puppet faces are also given added realism by having glass eyes, unlike the painted eyes of the earlier puppets. Something I find really interesting is that the marionettes can apparently be fitted with different heads, sculpted so that the face is smiling or frowning, which allows them to express emotion in a way that wasn’t possible in the earlier puppets.


Tell me Troy Tempest isn’t modelled on James Garner!

Stingray also has another claim to fame, it seems, as the first television series in the UK to be filmed completely in colour, even though it will be some years yet before Britain gets colour television (and probably a decade yet before we see it in Australia). I understand has been done in order to improve the possibility of sales into the American market, so I hope it works, and the Andersons make enough profit from Stingray to embark upon a new series in the not-too-distant future.

In the meantime, I look forward to belatedly seeing Fireball XL5 and enjoy it as an interim step between Supercar and Stingray!

[April 26, 1965] A Stranger in a Strange Land (The Stranger, Australian TV SF)

2 Comments


by Kaye Dee

I wasn’t contributing to the Journey last year, when Australia’s first home-grown science fiction television show, the children's series The Stranger, premiered in April 1964. So before the second series screens later this year, I thought I would take the opportunity to talk about this milestone in Australian television.


The screen title for The Stranger, with its unique, otherworldly script

Introducing G.K. Saunders

The Australian Broadcasting Commission (ABC) is the first local producer to show an interest in making science fiction for television, adapting The Stranger from a radio serial by prolific radio and television script writer Mr. G. K. "Ken" Saunders. A British-born New Zealander who moved to Australia in 1939, Mr. Saunders began writing scripts for ABC radio children’s programmes as well as radio dramas for one of the commercial networks.

During the War, Mr. Saunders also worked for the Council for Scientific and Industrial Research (CSIR). His exposure to scientific research seems to have sparked an interest in science fiction, because when he returned to writing scripts for ABC radio children’s programming, he produced about a dozen serials with science fiction themes. Mr. Saunders has said that he bases his science fiction on real science, and he consulted scientists from the Commonwealth Scientific and Industrial Research Organisation (CSIRO, the successor to the CSIR) to ensure this. But his stories also have a bit of a twist to them, and both these traits can be seen in The Stranger.


Recording an episode of the Argonauts Club, a popular children's radio programme that has been on air since 1941. Ken Saunders is best known as one of its main script writers since it began

Some of the science fiction serials Mr. Saunders wrote still stick in my mind. His first, The Moon Flower, was broadcast in 1953. It tells the story of the first expedition to the Moon, which discovers a tiny flower in a deep cave. This might seem a bit silly today, with what we now know about the Moon from Ranger 9 and other lunar probes, but back then some scientists still thought there might be simple life on the Moon. There was another one I really liked, in which the first expedition to Alpha Centauri discovers a planet inhabited by a human-like species who are pretty much like us – except they never invented music! I found this a fascinating idea.

The Genesis of The Stranger

Ken Saunders moved to England in 1957, working as a television and radio script writer for the BBC. This is where the story of The Stranger really begins: it was originally written as a six-part radio play for the BBC, which was broadcast in 1963, so perhaps some British readers of this article might even have heard it. From what my friend at the ABC has told me, it seems that the first series of the Australian television version is very similar to the original radio play storyline, with the six 30 minute television episodes drawn from the six parts of the radio serial.


Playing possum. A publicity still showing a scene from the opening teaser, where the stranger pretends to be unconscious at the door of Headmaster Walsh's house

Episode 1

Broadcast on 5 April 1964, the first episode of The Stranger begins with a short teaser: on a classic dark and stormy night, a figure makes its way along a dark street to the gate of a house. A signboard on the fence tells us this is the home of the Headmaster of St Michael’s School for Boys. This stranger walks to the door and lies down, carefully arranging himself to look like he has collapsed. He then taps weakly on the door and closes his eyes pretending he is unconscious. This is followed by the opening credits that are used for the rest of the series: the CSIRO’s Parkes Radio Telescope scans the skies in a timelapse sequence that then dissolves into a cosmic view of stars and nebulae against which the title The Stranger appears, written in an unusual, fantastical script. The author’s credit and episode number then appear over a slow pan of what seems to be a desolate, crater-pocked landscape. These images and the eerie, slightly foreboding theme music, set the scene for the mystery that follows and unfolds over the six episodes.

Headmaster Walsh and his family help the apparently sick stranger on their doorstep, who claims to have lost his memory but speaks with a European accent. When they discover that he speaks French and German there is speculation that perhaps he is Swiss. The rapidly recovering stranger declares that because he cannot recall his own name, he will give himself another: Adam, since he is a ‘new man’, and Suisse, since he is possibly Swiss.


What's in a name? The amnesiac stranger, who has christened himself Adam Suisse, with his hidden radio that sparks the suspicions of our three teenage heroes

Events then move quickly: Adam becomes a language teacher at St. Michael’s and takes up residence in a disused building on the school grounds. There, at the end of Episode 1, the teenage Walsh children, Bernie and Jean, and their friend Peter, accidentally discover a strange radio-like device, hidden under a loose floorboard. Turning it on, they hear speech in a foreign language.

Episode 2

The teenagers suspect that Adam is a spy. Although he attempts to allay their suspicions, Peter is not convinced, and they follow Adam on one of his weekend bushwalks in the Blue Mountains. Adam has spoken passionately about his love for walking in the bushland and being close to nature but disparages reports about flying saucers seen in the area where he likes to hike. Bernie, Jean and Peter try to track Adam through the bush and at the end of the episode come face to face with a hidden flying saucer!


Not what you expect to find on a bushwalk! The "flying saucer" piloted by Adam's friend Varossa, hidden away in the Blue Mountains

Episode 3

Adam takes the three teenagers onboard the flying saucer, revealing that he represents about 300 survivors living inside a colony ship created from a small planetary moon. Known as Soshuniss, the moon-ship has been travelling for generations since the planet from which its people originally came was poisoned and made unlivable by some kind of “accident”. The Soshunites seek a new home and have been reconnoitring the Earth. They would like to live here, but have no intention of invading, as they are a peaceful people. Back on Earth, the teenagers’ disappearance is treated by the police as an elaborate hoax, abetted by the missing Adam. When Adam and the teenagers arrive on Soshuniss, they are taken to an audience with the Soshun, the leader of the Soshunites.


Fly me to the moon! Adam reveals the truth about himself to Jean, Peter and Bernie, on board the spaceship travelling to the moon-ship Soshuniss

Episode 4

The surprised teenagers discover that the Soshun is a pleasant elderly woman. She asks them to deliver a letter to the Australian Prime Minister requesting permission for the Soshunites to settle in part of Australia. In return the Soshunites will share their scientific knowledge with the world. On returning to Earth with Adam and his friend Varossa, the young people’s story is disbelieved by their parents and the police. The Soshunites are arrested as kidnappers and spies, while visiting American scientist Prof. Mayer persuades the teenagers to prove their story by taking him secretly to the hidden spaceship they returned on. Although he is convinced of the truth of the story when he sees the spaceship, the police have been following them and Bernie attempts to take off with the others in the flying saucer to return it to the Soshunites.


Take me to your leader! Peter, Bernie, Prof. Mayer and Jean meet the Soshun, who can be seen in the background of this shot

Episode 5

Bernie is unable to properly control the spacecraft and the friends are rescued by another ship and taken to Soshuniss. The police who saw the flying saucer lift off contact the authorities and the spacecraft is tracked by radar and then the Parkes Radio Telescope to the moon-ship 50,000 miles into space. There is now no question that the aliens are real and the case becomes a Security matter. Although the Soshun sends Bernie, Jean and Peter back to Earth, Prof. Mayer stays on Soshuniss to learn more about it. Meanwhile, at the end of the episode, Adam and Varossa have escaped from prison and await rescue from Soshuniss.

Episode 6

In the final episode, matters come to a head. Bernie, Jean and Peter are pressured by the authorities to reveal where the Soshunites are hiding, as they are now considered alien spies. However, the Soshun has returned Prof. Mayer to the United Nations in New York, repeating her request to be allowed to settle in Australia in exchange for Soshunian scientific knowledge. He convinces a UN Special Committee and just as Adam and Varossa are about to be re-arrested by the police, word comes through that the UN has accepted the Soshunites' offer and they will be allowed to settle on Earth. The episode concludes on what is both a happy ending and a cliffhanger suggesting there is still more of the story to come….


TV Times preview article from April 1964 promoting the premiere of The Stranger

Australia's Answer to Doctor Who?

Although The Stranger is classed as a children’s programme, it has much to hold the attention of an adult viewer, just like Doctor Who, to which it is now being compared. However, producer Storry Walton dislikes the comparison and believes that the Australian show is more creative and has better production values, with more sequences filmed on location. Locations for the series included St Paul's University College in Sydney (in the role of St Michael’s school), the Blue Mountains, exteriors at the ABC headquarters campus (masquerading as various locations, including Idlewild Airport!) and Canberra.


On the set during the production of The Stranger while filming a scene on Soshuniss. Adam tells the trio from Earth that the Soshunites originally wore their hair long, but have cut it to fit in more comfortably on Earth.

Both Mr. Saunders and the Production Designer, Mr. Geoffrey Wedlock paid particular attention to portraying the Soshunians as a plausible, but alien, extraterrestrial society. Mr. Saunders created a language for the inhabitants of Soshuniss to speak among themselves, and it is believably and naturalistically spoken by the actors. When they speak English, all the Soshunians have a European-sounding accent, signifying that they are not speaking their native language. One of Saunders’ characteristic twists is that the Soshun is a woman, rather than a man as might be expected, and that her title is also the word for “mother”: Soshuniss therefore means “the motherland”. The CSIRO was also engaged to advise on the design of the Soshunian “flying saucer”, to make it as plausible a spacecraft as possible.

Underneath its well-crafted juvenile surface story, The Stranger also touches on some important issues including the treatment of refugees and European migrants to Australia and the concerns that many people are starting to have about industrial pollution damaging the environment. Although the “accident” that poisoned the Soshunian’s home planet is not specified, there are hints that its environment may have been destroyed by some kind terrible industrial accident that released toxic chemicals.


Veteran actor Ron Haddrick, well known to Australian viewers, gives adult nuance to his performance as Adam Suisse, the titular Stranger

The cast of The Stranger, while mostly actors well known in Australia, would not be familiar to those of you overseas, but I must mention the distinguished theatrical performer Ron Haddrick, who played the part of Adam Suisse without the least condescension to the younger viewers at whom the show is aimed, much like William Hartnell approaches his role on Doctor Who.

Coming Soon

The second series of The Stranger is due to start in July this year and hints of the new storyline are beginning to emerge. Storry Walton mentioned in a recent interview that the second series would complicate the political situation surrounding the Soshunians request to live in Australia, with a suggestion that doubts would begin to grow about the good intentions of the aliens. I’m quite looking forward to this new series and perhaps those of you in Britain and the US may get to see it too, as the BBC has already bought the first series for screening next year and there are rumours that it may be bought by a US network as well.

[April 6, 1965] The Early Bird Catches the Worm (INTELSAT 1)

2 Comments


by Kaye Dee

Later today, the International Telecommunications Satellite Organization, better known as INTELSAT is going to launch its first satellite, INTELSAT-1, which goes by the nickname of ‘Early Bird’. This satellite is intended to be the beginning of a global satellite telecommunications network, which INTELSAT hopes to have in operation by about mid-1967.


INTELSAT aims to connect us all via satellite – starting with the US and Europe

INTELSAT: Connecting the World with Space Technology

I wrote about INTELSAT last year, when the organization was first established in August 1964, with Australia as one of its 11 founding members. Around 45 countries have now joined the INTELSAT consortium and I’m certain that the creation of a world-wide telecommunications system that offers equitable access to all nations will improve international understanding and the prospects for world peace. Satellite communications will certainly prove a boon for countries with poorly-developed internal communications networks, as well as allowing major Southern Hemisphere nations like South Africa and Australia to have more rapid connections to Britain, Europe and North America.


One of the United States' first space stamps recognised the potential for satellite communications to promote world peace

Assuming all goes well with the launch this evening, INTELSAT-1 will be placed in a geostationary orbit at 22,300 miles above the equator, east of the Brazilian coast. Once the satellite has been thoroughly checked out to be sure it’s in full working order, it will go into operation, around the beginning of June, as the first commercial satellite providing regular telecommunications and broadcasting services between North America and Europe.

Soaring to New Heights

Of course, satellite communications between the Unites States and Europe isn’t completely new: Telstar and Relay 1 both provided this service back in 1962. But both satellites were only in low Earth orbit, so they could only provide intermittent service. When Syncom 2 and 3, were launched in 1963 and ’64, respectively, these experimental spacecraft built by the Hughes Aircraft Company demonstrated the feasibility of using satellites in geosynchronous and geostationary orbit to provide a world-wide communications system. They were so successful in connecting America with countries from Japan to Nigeria, that Syncom 3 was the prototype on which Early Bird has been modelled, and you can see the similarity in design.

Like Syncom 3, INTELSAT-1 is spin stabilised, which is the reason for its cylindrical shape. It has two 6-Watt transponders that enable it to carry 240 two-way voice circuits and one television channel, although not simultaneously: in order to transmit television, all the telephone voice channels have to be shut down.  An important difference between the two satellites, though, is that INTELSAT-1 uses commercial rather than military frequencies for its communications to and from the ground.

INTELSAT-1 weighs just 85-lb which, amazingly for its capabilities, is less than half that of Sputnik 1’s 184 pounds. It is covered with 6,000 solar cells that generate 45 Watts of power to operate the satellite. Early Bird’s capabilities are so advanced that it will actually be more economical to operate than international undersea cables, which carry fewer channels and cost nearly 10 times as much!

Getting into Position

Early Bird is being launched by a Thrust-Augmented Delta, the same type of rocket that was used to put Syncom 3 into orbit. This vehicle, also known as the Delta D, is essentially the same as its predecessor, the Delta C, but with the addition of three Castor-1 solid rocket boosters attached to the first stage. The launch is taking place at Cape Canaveral Air Force Station Launch Complex 17A, which was also used for Syncom 3’s launch. The Delta will boost Early Bird into an elliptical orbit, taking it from 830 to 22,950 miles out in space. After 40 hours a series of delicate manoeuvres will place the satellite in its permanent orbital position.

Demonstrating the Future

Although it will operate as a commercial service, Early Bird will also be used to demonstrate that international satellite telecommunication is commercially viable in the long-term. While its main ground stations will be the huge horn antennae originally built for Telstar, it will also use ground stations with large parabolic ground antennae with diameters of over 85 feet, like the one at Goonhilly in England, and perhaps smaller antennae as well.


The Telstar horn antenna at Pleumeur-Bodou, France, is now being used as an INTELSAT-1 ground station

From my friends at WRE who are involved with the NASA Gemini tracking station at Carnarvon, Western Australia, I understand that if the Early Bird experience goes well, the antennae for the INTELSAT-2 satellites, that are being contracted by NASA to support the Apollo programme, will be an unusual Cassegrain feed-horn design that is already being nicknamed the “sugar scoop”! I’m fascinated to see what this antenna will actually look like, with a nickname like that!

The other thing that INTELSAT-1 will be determining is whether or not the end to end signal delay of 250 milliseconds, while the signal goes up to the satellite and returns to the ground, will be acceptable to customers. Syncom 3 demonstrated that geostationary orbit is so high that, even at the speed of light, there is a perceptible time-lag between comment and response when communicating internationally. Whether people will find this too disconcerting for use with international satellite phone calls could have a significant influence on how future communications satellite systems are developed.


240 phones for 240 conversations simultaneously carried on via Early Bird. But will people accept the time-lag that comes with geostationary satellite communications?

So, my friends in the Northern Hemisphere, enjoy the convenience of satellite telecommunication that will soon be available to you-I can’t wait for it to come to Australia as well.

We had so much success with our first episode of The Journey Show (you can watch the kinescope rerun; check local listings for details) that we're going to have another one on April 11 at 1PM PDT with The Young Traveler as the special musical guest.  As the kids say, be there or be square!

[March 24, 1965] New Leaps Forward in Space (Voskhod 2, Europa F-3, Ranger 9, and Gemini 3)

1 Comment


by Kaye Dee

Returning to university kept me pretty busy in February, so I knew I wouldn’t have time to write, but this past month has seen yet more leaps forward in space exploration with the world’s first spacewalk and the launch of NASA’s first manned Gemini mission.

Soviet Space Achievements

It’s hard to believe that it’s just under four years since Yuri Gagarin rocketed into orbit as the first man in space. In that short time we’ve seen six flights in the Soviet Union’s Vostok program, including the first dual missions with two space capsules in orbit at the same time, and the first woman in space (how I’d love to meet Valentina Tereshkova!)


The first man and the first woman in space, Soviet cosmonauts Yuri Gagarin and Valentina Tereshkova

Just last year, the USSR gave us the first flight of its new Voskhod spacecraft, carrying a crew of three. At that time, my fellow writer, Gideon Marcus asked, what would the Soviets follow it up with? (see October 1964 entry)

Now we know. On March 18, the USSR launched a new Voskhod mission that has once again denied the United States a significant space first. This time, the Voskhod 2 mission included the world’s first spacewalk – about a year ahead of when NASA has anticipated accomplishing the same feat.

A Mystery Spacecraft

We don’t know a lot about the Voskhod spacecraft as the Soviet Union has released few pictures of it or statistics about it. It clearly must be substantially larger than the Vostok, since it has proved capable of carrying three people on its first flight, and two cosmonauts plus an airlock device on the recent spacewalking mission. We do know that, according to official figures, Voskhod 1 weighed 11,728lb, while Voskhod 2 weighed in at 12, 527lb – presumably because of the extra weight of the airlock it carried.

Newly Revealed Cosmonauts

The crew for this historic space flight were two cosmonauts whose names were previously unknown to us in the West: Colonel Pavel Belyayev, the mission Commander, and Lt. Colonel Alexei Leonov, who performed the actual spacewalk, or Extravehicular Activity (EVA) as NASA terms it. Leonov’s name will now go down in the history books as the first person ever to step outside a spacecraft into open space. Soviet cosmonaut biographies don’t really tell us very much, but both men are apparently Air Force fighter pilots, and are married with children. At 39, Col. Belyayev is the oldest person so far to make a space flight; he is also the oldest and highest ranking of the cosmonauts we know about.

Onboard Airlock

Voskhod 2 was launched at 07.00GMT (5pm Australian Eastern Standard Time) and it was just 90 minutes later, on the second orbit, that the spacewalk took place. At the time, Voskhod 2 was about 300 miles above the earth – the highest orbit by a manned spaceflight to date. Soviet sources describe the airlock that Leonov used to exit the ship as being mounted on the outside of the spacecraft and entered from the Voskhod cabin via a hatch. After the completion of the spacewalk, the airlock was jettisoned before the ship returned to Earth. Because the spacewalk would expose the crew to the vacuum of space if the airlock malfunctioned, both cosmonauts wore spacesuits for the duration of the mission, unlike the Voskhod 1 crew, who made their space flight in lightweight suits, which would seem to be an indication of Soviet confidence in the performance of the spacecraft.

Stepping into the Void

According to the TASS news agency, Lt. Col. Leonov spent 20 minutes “in conditions of outer space”. Since his actual spacewalk lasted about 10 minutes, the rest of the time must have been spent in the airlock. I’ve heard a rumour from my friends at the WRE that the spacewalk did not go as smoothly as the Soviets would like us to believe, and that Leonov actually had some difficulty re-entering the airlock, which might explain the times reported by TASS. But stories of Soviet coverups of problems with their cosmonaut program occur after every mission, so it’s hard to know quite where the truth lies in this instance.

Whether he had a problem or not, Leonov spent about 10 minutes floating in the void, attached to Voskhod 2 by a long umbilicus, to prevent him drifting away. His breathing oxygen was supplied from a tank on his back. Leonov said that he could look down and see from the Straits of Gibraltar to the Caspian Sea. The spacewalk was filmed and photographed from the Voskhod and I imagine that very few of the readers of this article will not have seen the breathtaking footage of Leonov somersaulting and making swimming movements as he floats in space with the Earth behind him (actually below, of course).

Problems in Orbit?

Voskhod 2 completed 17 orbits before returning to the Earth on 19 March, but there was a mysterious silence from Moscow about the mission after the 13th orbit, which has led to some speculation that there was a problem with the spacecraft, especially as it was not until about five hours after the crew had landed in the vicinity of Perm, west of the Ural Mountains, that their safe return was reported. Belyayev is reported to have brought the Voskhod back to Earth using manual controls. Although official statements said that this was part of the planned research programme, it might also be a hint that the mission experienced problems.

But whatever problems the mission may have encountered cannot detract from Lt. Col. Leonov’s historic achievement in making the first spacewalk, a technique that will be needed to advance future space activities. I wonder what new surprises Voskhod 3 will bring….

The Latest ELDO Test Flight

On 22 March, the ELDO program at Woomera also took another step forward with the third successful flight of the Blue Streak first stage of the Europa launcher. Launched at 8.30am local time, the rocket flew 985 miles, reaching a maximum altitude of 150 miles. This flight completes the first phase of the launcher development program: the next phase will begin with an all-up test of a live first stage with dummy upper stages.

Three for Three

Despite the clear success represented by Voskhod 2, it would be folly to overlook the fact that it has been a tremendous week for NASA.  The Ranger program, once the most ill-starred of NASA endeavors, has just completed its third successful mission in a row.  Less than six hours ago, at 3:08 AM PDT, Ranger 9 crashed into the crater Alphonsus in the lunar highlands.

The prior two successful Rangers, 7 and 8, were largely handmaidens to the Project Apollo.  They returned thousands of photographs of potential landing sites for the crewed lunar program.  Ranger 9, on the other hand, was the first mission with a primarily scientific aim.  In order for us to understand the Moon, its construction, and its history, we need close-up information on as many different types of terrain as possible — and no two regions of the Moon are more distinct from each other than the mountains of the lunar highlands and the relatively flat Maria or "seas".  Alphonsus is particularly interesting as it has a large central peak that may be evidence of lunar vulcanism from an ancient period.

Launched at 1:37 PM PDT on March 21, the Atlas Agena carrying Ranger 9 quickly disappeared into the cloudy sky.  The reliable booster's aim was true, propelling the spacecraft first into Earth orbit, and then off toward its final destination.  The next day, Ranger fired its own engines, correcting its course to mathematical perfection. 

Today, at Impact -20 Minutes, Ranger 9 warmed up its television cameras.  Images began appearing at the JPL auditorium…and around the nation, broadcast to anyone who was up to see it (and who had an online TV station to tune into!) This was the first time a robotic mission had been simulcast, and it was very exciting.  Now if only they could time their missions to be more accommodating to the aged thirty-nine year old science writers who cover them…

There were originally supposed to be 12, or even 15 Rangers, but because it took so long for them to work properly, there are now more advanced missions that are superseding them, namely Lunar Orbiter and Surveyor.  This is just as well.  While Ranger has been a triumph of engineering and science, bearing unexpected dividends in the successful spinoff spacecraft, Mariner 2, there is only so much one can learn from TV pictures.  Indeed, initial reports suggest that while Ranger 9's photos discovered new craters within Alphonsus that might be evidence for vulcanism, as Dr. Harold Urey quipped, it won't be until we have chemists on the Moon that we can draw solid conclusions.

In any event, bravo NASA, and bravo Ranger. 

Two in Three

After the spectacular mission of Comrades Tereshkova and Bykovsky in June 1963, there was a long pause in crewed spaceflight.  The Mercury program had ended in May '63 with the day-long mission of Gordo Cooper in Faith 7.  Talk of extending Mercury was poopooed (though you can get an idea of what might have happened if you read the excellent novel, Marooned).  For more than a year, as Mercury's 2-seat successor, Gemini, suffered delay after delay, we waited for Khruschev's shoe to drop.

And the Soviets did beat us back to space with their three-man flight last October, though the success of that mission was somewhat eclipsed by the Soviet coup that took place just a couple hundred miles beneath the orbiting space capsule.  Voskhod 2, with its remarkable space walk, only seems to further the Soviet lead.

Yet the American turtle still has ambitions to beat the Red Hare.  The third Gemini mission (the first and second were uncrewed test flights) had been planned for this month for some time, and yesterday morning, Gemini 3 took off from Cape Canaveral carrying astronauts Gus Grissom and John Young for a three-orbit test flight. 

A lot has changed since John Glenn's pioneering three-orbit flight in Friendship 7, just three years ago.  Both Grissom and Young were kept busy with a slew of biological experiments to conduct in orbit.  Grissom got to conduct the very first spacecraft maneuver, firing the ship's engines once per orbit to change its altitude and velocity.  Neither Mercury nor Vostok had this capability, and I haven't read anything that suggests Voskhod has it, either.  Score one for the home team!

In addition to the ordinary drama that attaches to every space mission, the astronauts created some of their own.  A couple of hours into the flight, as Gemini drifted along its second orbit, it was time for the astronauts to sample their carefully prepared space food.  This meal was lavishly prepared by NASA scientists to be nutritious, compact, and resistant to creating crumbs that could drift into and short vital ship components. 

Whereupon astronaut John Young pulled out a corned beef sandwich from his pocket, ate a bite, and offered it to his commander.  Grissom took a polite nibble, commenting on the sandwich's inability to stay together, and quickly put the thing in his pocket.  Apparently, this was all the brainchild of Schirra, the most renowned prankster of the Mercury 7. 

Beyond this incident, the very name Grissom chose for the first crewed Gemini was something of a scandal.  Christening a spacecraft has always been the privilege of its commander, and Grissom, sensitive to the fate of his last ship, chose an appropriate name: "Molly Brown."  This, of course, was the name of the eponymous character from The Unsinkable Molly Brown, a popular broadway musical about a survivor of the Titanic disaster.

NASA felt that the name lacked dignity and insisted on a change.  Grissom dug in his heels, insisting that if he had to change the name, it would be to Titanic.  NASA gave in.

Gemini 3 completed its three orbits without incident and reentered the atmosphere four and a half hours after leaving it.  Unfortunately, Molly Brown plunged back into the atmosphere somewhat off course.  Grissom tried to steer the capsule (such as it is possible to maneuver a shuttle-cock shaped craft) closer to the Atlantic recovery fleet, but the craft ultimately splashed down some 84 kilometers short.  It took a good half hour for the carrier, U.S.S. Intrepid, to arrive.  In the interim, Grissom and Young sweltered, the commander unwilling to open the capsule and risk another swamped spacecraft.  It is my understanding that Molly Brown is still decorated with Schirra's sandwich…

Minor issues aside, Gemini 3 was a fully successful flight, officially man-rating the Gemini spacecraft.  The next mission, currently scheduled for late spring, will feature the American version of the vacuum shuffle.  The first American spacewalk was originally planned for next year, but Leonov's jaunt changed all that.  Sometimes the rabbit gives the turtle a little goose…

(If you're wondering why the second Mercury astronaut got the honor of commanding the mission, it's because Alan Shepard, the first Mercury astronaut, has been taken off flight status due to an inner ear disease, and astronaut Slayton, the only Mercury astronaut who hasn't flown a mission, was grounded earlier for a heart condition.  I'd assumed that Wally Schirra would command Gemini 4 (Glenn retired to go into politics; Carpenter retired to become an aquanaut), and that Cooper would take Gemini 5.  Apparently, however, Ed White of the second group of astronauts so impressed his peers that he will command the next Gemini mission.  Because of the shifting Gemini schedules, Cooper is still taking Gemini 5, but Schirra is going after him, commanding Gemini 6.)

The Score

So there you have it.  In the last six months, the Soviets have orbited five men, one of whom stepped into Outer Space.  The Americans orbited just two, but they autonomously drove their own spacecraft.  Meanwhile, Ranger 9 raised the total of close-up pictures of the Moon to nearly 20,000 whereas the Russians still haven't added to the handful provided by Luna 3 more than five years ago!

I guess we'll see what happens.  Will the next flight be Gemini 4 or Voskhod 3?

We'll be talking about these space flights and more at a special presentation of our "Come Time Travel with Me" panel, the one we normally do at conventions, on March 27 at 6PM PDT.  Come register to join us!  It's free and fun…and you might win a prize!

[January 20, 1965] The T.A.R.D.I.S. Lands Down Under and Japan Invades Australia (Doctor Who and The Samurai)

1 Comment


by Kaye Dee

I’ve been reading Jessica Holmes’ insightful articles about the British science fiction television series Doctor Who since she first started commenting on this show (see December 1963 entry) and I’ve been looking forward for some time to actually seeing it air in Australia. At last my wish has been granted! The T.A.R.D.I.S. has finally landed here, with Doctor Who commencing on the Australian Broadcasting Commission (the ABC is the Australian equivalent of the BBC) just in the past week, mesmerising me with those incredible opening credits.


Doctor Who's ethereal and abstract opening credits perfectly suggest travelling along the corridors of time

Not Just Kid Stuff

I heard from a friend who works at the ABC that Australia has been one of the first countries to buy Doctor Who from the BBC. In fact, I was really excited when he told me in March last year that the ABC had purchased the show and intended to debut it last May, but then delays arose due to censorship issues. Yes, although Doctor Who is classed as a family show in Britain, the Australian censors (who view and classify every overseas television show that comes into the country) have deemed the first thirteen episodes to be not suitable for children and classified them as “Adult”! This means that the ABC must schedule these episodes for screening after 7pm and couldn’t show Doctor Who in the Sunday night 6.30pm timeslot it originally planned. But at last Doctor Who has found a home on Friday night at 7.30pm (at least in Sydney). I just hope the censors aren’t going to decide one day that some stories are too scary to be screened at all!

Doing the Rounds

A funny thing about the ABC is that sometimes when it buys a show from overseas it only purchases one film copy of each episode. This film reel then has to be sent around from state to state so that it can be screened by the ABC broadcaster in each capital city. So, the first Australian screening of Doctor Who was actually in Perth on Tuesday, 12 January. Sydney and Canberra (linked by cable) were next on 15 January. Brisbane will get to see Doctor Who next Friday 22 January, but Melbourne will have to wait until Saturday 20 February and Adelaide won’t see the first episode until Monday 15 March! I’m glad I live in Sydney now.


Anthony Coburn (left) and Ron Grainer (right) may be virtually unknown in Australia, but they've had successful careers in Britain and have made important contributions to the creation of Doctor Who

The Australian Connection

It’s great to see that some Australians are involved with the production of Doctor Who. The premiere story, “An Unearthly Child” has been written by Anthony Coburn. I’d never really heard of him before, but according to a few newspaper articles reviewing the first episode he was born in Melbourne and has been working in England for many years as a staff writer for the BBC. Ron Grainer, who composed the wonderfully eerie and evocative theme music, has also spent most of his professional career composing music in Britain, although he grew up in a small mining town in far north Queensland. Vicki Lucas’ fascinating article on the music of Doctor Who (see December 1963 entry) tells me that an obviously talented lady named Delia Derbyshire at the BBC’s Radiophonic Workshop created the amazing sound of Grainer’s composition: all I can say is that I’m in awe of her skill at creating electronic music, now that I have actually heard the theme tune for myself.


The mysterious Doctor Who and his granddaughter Susan. I wonder when we'll find out where they really come from and why they are exiles from their home world

A Family Viewing Experience

And that’s what I’ve discovered with the first episode of Doctor Who: it’s one thing to read about the show and look forward to seeing it, but it’s a whole new experience to actually watch it on television. My sister Faye and her kids watched “Unearthly Child” with me and we were all caught up in the mystery of Susan and her grandfather and what's going to happen to the two school teachers now that they've been whisked away somewhere in time and space in the Doctor’s T.A.R.D.I.S. Vickie and David certainly didn’t think that Doctor Who was just for adults, no matter what the censors said! We’re all looking forward to the next episode and enjoying the adventures that those of you in Britain have been watching for over a year.

Japanese Television Arrives in Australia

Doctor Who isn’t the only new television import to catch my attention lately. Despite the animosity that many Australians have felt towards Japan since the War, last year’s Tokyo Olympic Games, where our young swimmer Dawn Fraser did so well, sparked a lot of interest and curiosity about Japan and its culture. So much so, in fact, that TCN-9 in Sydney started showing the first ever Japanese television series on Australian screens at the end of December. It’s an action adventure series called The Samurai, set in feudal Japan three centuries ago. Channel 9 is taking a gamble with this show, which I guess is why they’ve put it on in the doldrums period of the Summer holidays.


Shintaro narrowly avoids a brace of 'star knives' (a weapon used by the ninjas). I've heard that Dads are now making home-made ones for their kids, snipped from used tin lids. It'll be fun to play samurai and ninjas until someone gets hurt with one of these!

A "Western", Japanese Style

The Samurai tells the story of a master swordsman named Shintaro (the “samurai” of the title), a half-brother of Japan’s young ruler, the Shogun, who travels around Japan putting down plots against his brother’s government, usually by the villainous gangs of a semi-magical secret society known as ninjas: you could say that Shintaro is a medieval Japanese cross between James Bond, a Western gunslinger and Robin Hood! Channel 9 has been showing The Samurai five days a week at 3.30pm and with its exotic setting, supernatural action and endearingly bad dubbing with broad American accents, it’s fast becoming very popular – and not just with the kids. Faye’s husband, Bruce, has been absorbed in the show while he’s on holidays and I’ve taken to this fascinating curiosity of a show as well. Mind you, so many ninjas get killed in each episode, I’m surprised the censors haven’t labelled The Samurai as “Adult”, alongside Doctor Who!

Japan Invades the Top 40, Too

Another bit of Japanese culture has also been making its presence felt in the Top 40 charts. In August last year, the lovely Noeleen Batley, Australia’s first female pop singer to have a national hit song, released an English version of a song that was a huge hit in Japan in 1963. “Little Treasure from Japan” charted in Sydney and Brisbane and even made it all the way to #16 in Melbourne last October. It really is a sweet little song, with one of those tunes you can’t get out of your head. My niece Vickie’s dance teacher is already creating a dance routine for her class to perform to the song for their mid-year concert. Now we just have to figure out where we can find a kimono for her costume.


Australia's "Little Miss Sweetheart" Noeleen Batley has had a hit with "Little Treasure from Japan". You can see by the wear on the cover that Faye's copy of the record has already been played quite a bit

Australia International

The fact that Channel 9 took a risk on screening The Samurai is an indication of how much Australians have broadened their worldview since the end of the War. The large influx of European migrants has introduced us to delicious new foods, good coffee (thank you!) and a more cosmopolitan outlook. Our TV might be dominated by British, American and (a long way third) Australian shows now, but hopefully we'll soon see more international programmes. Perhaps someday we'll even see a television channel offering programmes from around the world: I can't wait to see what fun and entertainment we've been missing out on!

[January 8, 1965] The Skylark of Space (Britain's Skylark Sounding Rocket)

9 Comments


by Kaye Dee

Hopefully Doc Smith will forgive me for borrowing the title of his famous story for my article, but I couldn’t resist because it fits so well. Since I began writing here, I’ve been wanting to talk about the Skylark sounding rocket, the first British rocket capable of reaching space (whether you go by the US Air Force and NASA definition of space beginning at 50 miles, or accept the Federation Aeronautique Internationale definition, based on the work of Theodore von Karman, of 100 kilometres/62 miles).


A different kind of Skylark reaching for the stars!

Hatching the Skylark

Sounding rockets, which can carry payloads into space, but do not have enough thrust to put them into orbit, are often neglected when discussing the Space Race. But they are perhaps more important (and certainly more often launched!) than satellites.

These suborbital rockets were still a relatively new technology a decade ago, and even by the end of the International Geophysical Year (IGY) only a handful of countries (including Australia, I’m proud to say) had developed a national sounding rocket capability. First announced in 1955, the Skylark sounding rocket was developed for the IGY by the UK Ministry of Defence’s Royal Aircraft Establishment (RAE), in collaboration with the Royal Society’s Gassiot Committee, which focuses on meteorology and upper atmosphere research.


Diagram showing the original design for the Skylark rocket. The design has been evolving ever since, improving the capabilities of the vehicle

The new rocket was originally called the Gassiot High Altitude Vehicle, which is a bit of a mouthful, and the story is that, in 1956, one of the engineers working on the rocket’s design at the RAE decided that he would like to see it named “Skylark”. I don't know if he was a fan of Doc Smith's work, but a class of UK rocket motors is named after British birds, so that was more likely his inspiration for the name. In any case, he apparently put up a paper to his superiors suggesting that the rocket should be renamed to something that would simpler and more memorable for public relations and offered a list of alternatives, none of which were particularly appealing except, very deliberately, Skylark. The plan worked, and the name Skylark was approved for the rocket.

Flying to Australia

Sounding rockets, like test missiles, need a lot of empty land on which to fall back to Earth; Woomera was the obvious place for Britain’s new scientific rocket to be launched. Skylark components and payloads are made in the UK and then flown to Australia by transport planes. These include a special dedicated “explosives” transport plane that carries the rocket engines to Australia fully-loaded with their solid propellant. The rocket motors are delivered directly to Woomera, while the payload parts arrive at the Weapons Research Establishment’s (WRE) Salisbury facility, near Adelaide (see June entry), where they are assembled by WRE technicians and British payload specialists and then transported to Woomera to be fitted to the launch rocket.

Because of its slow acceleration, the Skylark needs a very long launch rail to ensure its stability in flight and this massive tower dominates Range E at Woomera, where the sounding rocket launches take place. It’s 80 feet tall and weighs 35 tons, so transporting it to Australia was quite a task. Interestingly, because of steel shortages in Britain when the tower was being designed, it’s actually made out of war surplus Bailey bridge segments!

Skylark Acsending

The first Skylark launch took place in February 1957, before the official start of the IGY in July that year, with the first three flights being performance-proving flights. On its fourth flight, in November 1957, the Skylark showed that it could reach the space environment, soaring to an altitude of 79.5 miles. This flight was also the first to carry a suite of scientific instruments provided by British universities, including two experiments that have since been flown on many Skylarks: a ‘grenade’ experiment and a ‘window’ experiment. In the grenade experiments, grenades are ejected from the rocket during its flight and the explosions detected on the ground by microphones and flash detectors. From these measurements, temperatures and wind velocities at different altitudes can be determined. In the ‘window’ experiment, strips of radar chaff (also known as ‘window’) made from aluminium are ejected into the atmosphere to be tracked by radar, which provides velocity measurements of upper atmosphere winds.


I love this timelapse photo of a Skylark night launch, taken in 1958. SL04, the first Skylark to reach space, was also launched at night, although it seems that no-one thought to take a picture of that historic launch!

Of course, since 1957, the number and range of scientific experiments being flown on Skylarks has steadily increased, helping to provide a new understanding of the conditions in the upper atmosphere and the fringes of space. When the first experiment releasing sodium vapour into the atmosphere to study atmospheric density and winds flew in late 1958, people in areas hundreds of miles from Woomera thought that the strange sight of a reddish-yellow cloud might be associated with Sputnik III, the massive Soviet satellite that was in orbit at the time!

Skylark Improving

The original design of the Skylark rocket used a single Raven solid rocket motor. To increase its altitude and payload carrying capacity, different variants of the Raven have been used, and in 1960 the Skylark became a two-stage launcher, with the use of a Cuckoo motor for an additional boost on some flights. There have also been experiments with a parachute system, to try to recover some instruments or photographic plates intact, but so far these have not been very successful.

Until very recently all Skylark flights were unstabilised, but just last year there were two experimental flights using Sun sensors to provide stabilisation. The development of this technique will make the Skylark more suitable for taking astronomical observations at high altitude, above the thickness of the atmosphere, and I’ve heard that there are plans for small X-ray and Ultra-violet telescopes and other astronomy payloads to be flown on future launches.

At the end of September the Skylark notched up its 100th flight, which is perhaps not surprising as the launch rate has been steadily increasing. There were 19 flights in both 1963 and 64, and this year looks as if it will be even busier. The WRE has a section that manages the Skylark launches – the Research Vehicles Group: because of the high rate of firings and the time it takes to prepare each rocket for launch, there are four Skylark launch teams within the Group, each one dedicated to a specific Skylark flight.

1964 also saw another new step for the Skylark, with two launches taking place for the European Space Research Organisation (ESRO) at Italy’s Salto di Quirra Range on Sardinia. This range was established in 1956 under the management of Luigi Broglio, who I mentioned last month as the mastermind behind Italy’s first satellite (see December entry). This Range is providing facilities to ESRO until its own sounding rocket facility near Kiruna in Sweden is completed.

Skylark looks set to become the workhorse of the European sounding rocket program, just as it is for Britain. NASA has even launched Skylarks out of Woomera: as part of a co-operative Ultra-violet astronomy programme with Australia, four ‘NASA’ Skylarks were launched at Woomera in 1961

Skylark in Orbit

Skylark rockets have also played a role in Britain’s Ariel satellite programme, helping to test out instrumentation and experiments before they were included in the satellites. Like Canada , Britain launched its first satellite, Ariel 1, in 1962 (see September entry), with help from the United States, which provided the satellite body in which the British experiments were installed, as well as the launch. In March last year, Ariel 2 was launched for Britain by NASA. In advance of both these flights, so much of the equipment was checked out beforehand on Skylark flights that I’ve heard that some wit described the satellites as “Skylark in orbit”!

Britain's Ariel 1 and 2 satellites are almost identical. The scientific instruments on both were tested out on Skylark flights before being launched into space

It's been exciting to watch the progress of the Skylark programme and I expect that this versatile sounding rocket will be operational for many years to come. Australia has it's own sounding rocket program that has been designed to complement the Skylark research in many ways. I'll have to devote an article to it in the not too distant future

[December 21, 1964] Italy Joins the Space Race! (San Marco 1 and Explorer 26)

4 Comments


by Kaye Dee

The biggest news in space this month is that Italy has joined the Space Race, with the launch of its first satellite San Marco 1. Named in honour of Saint Mark the Evangelist, the patron saint of Venice and protector of Venetian sailors, the San Marco launch is the first mission in a programme that began in 1961.

The Italian von Braun

The San Marco satellite programme is the brainchild of Luigo Broglio, an Italian military officer and aerospace engineer who’s already earned himself the nickname “the Italian von Braun”. Broglio established the Salto di Quirra missile test range on Sardinia in 1956, which is now also being used to launch British Skylark rockets (like those being used for upper atmosphere research at Woomera) for the European Space Research Organisation (ESRO). ESRO is the sister program to ELDO (see June entry), developing the satellites that will fly on ELDO’s Europa rockets. Convinced by Italian physicist Prof. Edoardo Amaldi (a co-founder of ESRO) that Italy should have its own space program, Broglio persuaded the Italian Prime Minister in early 1961 that Italy should develop a national satellite program and its own satellite launching facility.


Luigi Broglio was both an officer in the Italian Air Force and the Dean of Aerospace Engineering at La Sapienza University

As it happened, the international Committee on Space Research (COSPAR) was meeting in Florence in April that year, so Broglio took the opportunity of discussing with NASA Italy’s participation in the same program that has already enabled Canada and Britain to launch their satellites on NASA rockets (see September entry)

San Marco Approved

The Italian Government approved the San Marco programme in October 1961 with the task of building the San Marco satellites allocated to the Commissione per le Ricerche Spaziali (CRS), or Commission for Space Research. This group of distinguished Italian scientists and engineers was initially formed by Amaldi and Broglio within the Consiglio Nazionale delle Ricerche (CNR), the Italian National Research Council, to canvass support for an Italian space programme.

A formal Memorandum of Understanding between the CRS (represented by Broglio) and NASA (represented by Deputy Administrator Hugh Dryden) was signed on 31 May 1962. Under this MOU, the United States agreed to provide Scout rockets to Italy and train the Italian launch crew, while Italy developed its satellites and built a national launch facility. NASA also agreed to provide two sub-orbital test flights from its Wallops island launch facility, using Shotput sounding rockets, so that the Italian launch crew could gain experience in launch procedures and the CRS could test instruments for the first satellite. These two test flights took place in 1963.

Italy decided that its national launch facility would be a modified mobile oil rig platform, that would be towed to an equatorial location off the coast of Kenya. This would enable the Scout rockets to be fired to the east and take advantage of the boost provided by the Earth’s rotation. The Italian oil company Eni was contracted to provide the mobile launch platform, but the construction has been delayed and the offshore facility will not be ready until sometime next year.

Liftoff for San Marco 1

Because of the delays with the launch platform development, San Marco 1 (also known as San Marco A) was fired from Wallops Island as a training exercise for the Italian launch crew ahead of future launches in the Indian Ocean, with the successful launch taking place on 15 December (16 December here in Australia).

The battery-powered satellite sat directly on top of the Scout’s fourth stage, with both the rocket motor and satellite contained within the fairing. The spherical satellite has a total mass of 254 lbs. and a diameter of 26 in. Four antennas are spaced around the equator of the satellite, which is painted longitudinally in black and white for thermal control.

The main purpose of the San Marco programme is to conduct ionospheric research. However, being essentially a test satellite, San Marco 1 is only carrying a few experiments. Its major scientific instrument is the “Broglio scale”, which is designed to measure the density of the atmosphere at very high altitudes, although lower than the typical orbital altitudes used by other satellites. The CRS hopes that San Marco 1 and future missions will help to create a more precise model of the upper atmosphere in the low orbit environment. This should improve the re-entry predictions for both spacecraft and missiles. San Marco 1’s other main instrument is a radio transmitter, intended to study ionospheric effects on long-range radio communication. Undoubtedly, the future satellites in the series will be more sophisticated.

An interesting aspect of San Marco 1’s launch is that, although it took place in the US, the launch was handled by a NASA-trained Italian launch crew. This places Italy in a unique situation: unlike Canada and Britain, which provided their first satellites to NASA for launch on American rockets by American personnel, Italy effectively launched its own satellite. In fact, Italy now considers itself the third country in the world to operate its own satellite, after the Soviet Union and the United States.


Thanks to Uncle Ernie the stamp collector, here is one of the new launch covers for San Marco 1, highlighting its unique status as an Italian-launched satellite

San Marco 2 is scheduled to launch next year, and I’ll look forward to seeing Italy launch that satellite from its new national facility, which should be in place in Kenya by then.

Another Explorer in Orbit

As I write this, I’m delighted to report that another Explorer satellite has just been confirmed as safely in orbit! NASA is certainly committed to this programme, with such a regular series of satellites designed for understanding the space environment surrounding the Earth (see September entry). Explorer 26 is the latest probe in the series, designed to measure the Earth’s magnetic field and trapped high energy particles within it.


Explorer 26 is similar in design to its predecessors in the Energetic Particle Explorer series.

Explorer 26, also known as Energetic Particle Explorer (EPE)-D and S-3C, is a spin-stabilised, solar-cell powered satellite, weighing 101 lbs and carrying five experiments. Four of these instruments — the Solid-State Electron Detector, Omnidirectional and Unidirectional Electron and Proton Fluxes, Fluxgate Magnetometers and Proton-Electron Scintillation Detector — are designed for geomagnetic and high energy particle studies. The fifth experiment, the Solar Cell Damage experiment, is designed to quantify the degradation in solar cell performance due to radiation and evaluate the effectiveness of glass shields at preventing this degradation. I find this experiment particularly interesting, as solar cells are becoming increasingly used on satellites to provide power supplies that will last much longer than batteries.

The Energetic Particle Explorer series began in 1961 with Explorer 12 (EPE-A), launched in August 1961. All the satellites in the series so far have had the same basic design, but with progressively heavier instrumentation weight. They have all been launched from Cape Canaveral by Thor Delta vehicles.

Dreams for Down Under

I'm envious that Italy has been able to get its own space programme underway, while we here in Australia seem to have no immediate prospect of launching a national satellite. But I shouldn't complain too much: 1964 has been a very exciting year for space activities Down Under, with the ELDO programme finally underway. I’m looking forward to even more significant space achievements in 1965!

[November 23, 1964] Let’s Go Exploring! (NASA’s latest Explorer satellites)

2 Comments


by Kaye Dee

I’ve written before about how much I love satellite spotting and this month has given me three new ‘man-made moons’ to watch out for, with the latest additions to NASA’s Explorer scientific satellite program. Each of the new Explorer satellites is very different and their research tasks are all of real interest to me, as I’m concentrating on space physics for my Masters degree. But before I talk about them, I’m excited to share the most recent news from Woomera.

A Textbook Test Flight

On October 20, the second test flight of the Blue Streak stage for ELDO’s Europa launch vehicle took place. After the problems that occurred towards the end of the first test flight, which led to the rocket’s flight falling short of its intended landing area (see June entry), this latest launch was a complete success, demonstrating that the fuel sloshing issue has been solved. The engines fired for the 149.1 seconds, fractionally over their anticipated performance, and the Blue Streak impacted almost 1,000 miles down range. Everyone at the WRE is really pleased (and relieved) with this textbook test flight, as it means that the Europa development program can now keep moving forward. Can’t wait for the next test flight!


Blue Streak F-2 prepares to blast off at Woomera’s Launch Area 6.

But what has really captured my attention this month are the new missions in NASA’s Explorer program (which I last covered on September 6 and October 16). This series of scientific satellites continues to study the near space environment around the Earth and the nature of the Sun, as well as contributing to astronomy and space physics. 

Taking a Hit for Science

Explorer 23 was launched on 6 November, using a Scout rocket fired from NASA’s Wallops Island facility in Virginia, from which many satellites in the Explorer series have been launched. Also called S-55C, Explorer 23 is the third in a series of micrometeoroid research satellites. Explorer 13 (launched in August 1961) was the first in the series. It was also known as S-55A, following the failure of its predecessor, the original S-55 satellite (the S standing for Science). Explorer 16 (S-55B) was launched in December 1962. The purpose of the S-55 series is to gather data on the micrometeoroid environment in Earth orbit, so that an accurate estimate of the probability of spacecraft being struck and penetrated by micrometeoroids (very tiny pieces of rocks and dust from space) can be determined.


Explorer 13 was the first micrometeoroid research satellite to take a hit for science.

Each of the S-55 spacecraft is about 24 inches in diameter and 92 inches long, built around the burned out fourth stage of the Scout launch vehicle, which forms part of the orbiting satellite. Explorer 23 carries stainless steel pressurized-cell penetration detectors and impact detectors, to acquire data on the size, number, distribution, and momentum of dust particles in the near-earth environment. Its cadmium sulphide cell detectors were, unfortunately, damaged on lift-off and will not be providing any data. Explorer 23 is also designed to provide data on the effects of the space environment on the operation of capacitor penetration detectors and solar-cell power supplies.

Two Satellites for the Price of One Launch

November 21 saw the Explorer 24 and 25 satellites launched together on a Scout vehicle fired from Vandenberg Air Force base in California, which will put the satellites in a near-polar orbit. These two Explorers have been launched as part of the research program for the International Quiet Sun Years (IQSY). Just as the International Geophysical Year took place in 1957-58, during a period when solar activity was at its height, the IQSY is focusing on the Sun in the least active phase of the solar cycle, across 1964-65. This makes it possible to compare the data from Explorer 24 and 25 with earlier observations made from orbit when the Sun was more active. Having the satellites in dual orbits also makes it possible to compare the atmospheric density data gathered by Explorer 24 directly with the radiation data from Explorer 25.

Explorer 24: A Balloon in Orbit

Although the two satellites work in conjunction with one another, they couldn’t be more different! Explorer 24 is a 12-foot diameter balloon made of alternating layers of aluminium foil and plastic film. It’s covered all over with 2-inch white dots that provide thermal control. Deflated and packaged in a small container, the balloon was packed on top of the Explorer 25 satellite for their joint launch and then inflated in orbit. A timer activated valves that inflated the balloon using compressed nitrogen. This process took about 30 minutes, after which the satellite was pushed away from the carrier rocket by a spring.


Explorer 24 hitched a ride to orbit on top of Explorer 25, before being inflated in space.

Explorer 24 is identical to the previously launched balloon satellites Explorer 9 (launched in February 1961) and 19 (launched in December 1963). Explorer 19 was also known as AD-A (for Air Density) and Explorer 24 is also designated as AD-B.  All three of the balloon satellites have been designed to provide data on atmospheric density near the perigee (lowest point) of their orbit, through a series of sequential observations as they move across the sky.

Like its predecessors, Explorer 24 will be tracked both visually and by radio, as it carries a 136-MHz tracking beacon. Explorer 19’s tracking beacon failed while it was in orbit, and so it could only be tracked visually by the Smithsonian Astrophysical Observatory’s network of Baker-Nunn telescope cameras. There is one of these stations at Woomera and my former computing colleagues at the WRE’s Satellite Centre in Salisbury, South Australia, assisted with converting its observations into the orbital calculations that the scientific researchers needed. 

Explorer 25: Studying the Ionosphere

Explorer 25’s primary mission is to investigate the Ionosphere, make measurements of the influx of energetic particles into the Earth’s atmosphere, studying atmospheric heating, as well as the Earth’s magnetic field. It will be magnetically stabilised in orbit through the use of a magnet and a magnetic damping rod and carries a magnetometer to measure its alignment with the Earth’s magnetic field. One of its particularly interesting tasks will be to study and compare the artificial radiation belt created by the Starfish Prime high-altitude nuclear explosion and the natural Van Allen radiation belts.

Explorer 25 is also known as Injun 4 and Ionosphere Explorer B (IE-B). It is the latest satellites in the Injun series, which have been developed at the University of Iowa under Professor James Van Allen, after whom the Van Allen radiation belts are named. Van Allen himself gave these satellites the name Injun after the character Injun Joe in Mark Twain’s Adventures of Tom Sawyer. The first three Injun satellites were only qualified success and were not actually part of the Explorer program. However, as IE-B, Injun 4/ Explorer 25 extends the research being carried by Explorer 20, that I wrote about in September.

With him are William Pickering (left), the Director of the NASA’s Jet Propulsion Laboratory and (right) Wernher von Braun, whose team developed the Juno rocket that launched Explorer 1.

Explorer 25 is roughly spherical and almost 24 inches in diameter. It has 50 flat surfaces: 30 of them are carrying solar cells that are used to recharge the batteries that power the satellite. The satellite is also equipped with a tape recorder and analogue-to-digital converters, so that it can send digital data directly to a ground station at the University of Iowa.

Science Streaks Across the Sky

It is simply marvelous how rapidly we are expanding our knowledge of the universe above. Just seven years ago, there hadn't been a single Explorer; now there are twenty five! I’m looking forward to spotting all these science gatherers in the evening sky over the coming weeks — and eventually telling you what they find up there!

[October 6, 1964] Up, Up and Away! Supersonic Aircraft Test Flights

2 Comments


by Kaye Dee

I’m fascinated by supersonic aircraft design, so the end of September gave me plenty to get excited about with the first test flights of some of the West’s most advanced military aircraft. On September 21 in the US, the North American Aviation XB-70 Valkyrie flew for the first time. This prototype has to be one of the most gorgeous aircraft ever designed: with its delta wing and needle nose, it looks like it has flown off the cover of a science fiction magazine! It reminds me a lot of the prototype designs for the Anglo-French Concorde on which the British aircraft industry is pinning its hopes for future aviation industry dominance.


A model of the Concorde prototype design at the Farnborough Airshow in 1962. Delta wings are clearly in fashion for supersonic aircraft

XB-70: Floating on Air

The Valkyrie was designed to be a high-altitude Mach 3 strategic bomber, although the operational B-70 version was cancelled back in 1961 and the aircraft will now be used to test new supersonic aviation technologies. One of the heaviest aircraft in the world, according to Flight magazine, the XB-70 is constructed mostly of stainless steel, sandwiched honeycomb panels, and titanium. Like the Concorde, the Valkyrie boasts a droop-snoot, or lowerable nose, that allows the pilots to view the ground during its nose-high take-off and landing.


The final design drawing for the B-70 bomber, for which the Valkyrie was intended to be the prototype

What I find particularly interesting about the XB-70 is that it uses the technique of compression lift to improve the overall lift of the aircraft and increase its directional stability at supersonic speeds. Only discovered in the 1950s, the compression lift effect is generated by a shock wave that is created when air strikes the sharp leading edge of the central engine air intake splitter plate below the wing, behind which are six General Electric YJ93-GE-3 turbojet engines. This effect is strengthened by the downward folding wingtips that help to trap the shock wave under the wings. Yes, the XB-70 actually has hinged wingtips that tilt down as far as 65 degrees!


The XB-70 Valkyrie ready for its first test flight. Note the hinged wingtips are in the horizontal position for take-off

The Valkyrie’s maiden test flight saw it hop between the manufacturing facility at Palmdale, in California, and Edwards Air Force Base. It wasn’t all smooth sailing, though, as one engine had to be shut down shortly after take-off and an undercarriage malfunction warning meant that the flight was flown with the undercarriage down as a precaution. This limited the flight to a speed of 390 mph, which was about half of what had been planned and only a fraction of the XB-70’s 2,000mph maximum speed. Additionally, during landing the rear wheels of the port side main gear locked, causing two tyres to rupture and start a fire. Despite these teething problems I’m looking forward to future test flights of this amazing aircraft—the next one is due in a couple of weeks, so maybe I’ll write more about it next month.


As the Valkyrie lifts off we get a good view of the air intake splitter that generates the shockwave for the compression lift effect. Its six engines are housed behind the air intake

TSR-2: A Cross Between a Bomber and a Missile

Oddly enough, while Britain’s latest RAF prototype is also delta-winged and powered by two Olympus 320 engines, similar to those that will be used on the Concorde, it resembles the Concorde far less than the Valkyrie, though it still looks sleek and deadly! The TSR-2—the name is derived from its role as a “tactical strike and reconnaissance” bomber— took to the skies for a 15-minute test flight on September 27 at the Ministry of Aviation's Aeroplane and Armament Experimental Establishment at Boscombe Down. The test flight looked to be quite successful, though I’ve heard on the WRE grapevine that the aircraft actually had many problems and was only marginally ready for a test flight.

Developed by the British Aircraft Corporation (BAC), the TSR-2 is designed to make its attack run at ground-level, under the control of terrain-following radar. It’s a ‘short take-off and landing’ vehicle that can carry conventional or nuclear weapons and is capable of flying above Mach 2 at 40,000 ft or around Mach 1 during low-level bombing runs. This versatility places the aircraft at the intersection of the capabilities of the manned bomber and the long-range missile. The TSR-2 is similar to the Valkyrie in that it has downturned wingtips, fixed at an angle of 30 degrees, to enhance its stability in high speed flight. However, as its test flight showed, those wing tips generate trailing white vortices, which might make the TSR-2 less than inconspicuous during an attack run!


On a ground attack run, the TSR-2 will be advertising its position with its smoking exhaust and white wing vortices

The TSR-2’s development has been fraught with controversy and more than once threatened with cancellation. Some commentators are calling this test flight the current British Government’s last political act before the upcoming elections in Britain, and I guess only the future will tell whether the TSR-2 goes on to become operational, or whether the next Government will finally cancel the plane and buy a replacement from America instead.


The YF-12A at Edwards Air Force Base before its first public test flight

YF-12A: Fast, Powerful and Just a Bit Mysterious

Another US Air Force prototype has been the most recent test flight to catch my attention, with the Lockheed YF-12A unveiled to the world at a press conference at Edwards Air Force Base on September 30. Claimed to be "the world's fastest military aircraft" (though perhaps the XB-70 would beg to differ), the YF-12A is a prototype interceptor capable of reaching 2,000 miles per hour and an altitude of over 80,000 feet. With its long, sleek fuselage and huge engine nacelles mounted on either side of the body (carrying the two Pratt & Whitney J58 turbojets that power it), the YF-12A is another design that looks like something out of a science fiction film, but it certainly conveys an impression of high speed and I suspect it will be setting new speed and altitude records before too long.


The pressure suits worn by the YF-12A crew don't look much different from an astronaut's spacesuit. It really helps to show how high this bird can fly!

Made mostly of titanium, to handle the heat generated by its high speeds, the YF-12 is painted dead black, to help radiate the heat from its skin. It carries a crew of two: a pilot and a fire control officer, to operate the air-to-air missile system, which includes a powerful radar and four Hughes AIM-47A Falcon air-to-air missiles carried in chine bays within the fuselage. Unlike the Valkyrie and the TSR-2, it uses a skid landing system, rather than a more conventional undercarriage. There isn’t a lot of detail available yet about the YF-12A, and rumour has it that it is the ‘public version’ of an aircraft that is still top secret, but I certainly hope to see more of it in the future.
