[May 30, 1964] Every journey begins… (Apollo's first flight!)

Leave a comment

One Step

Humanity took its first halting steps toward the Moon with the (mostly) successful launch of the first Apollo spacecraft into orbit on May 28, 1964.  Blasting off from Cape Kennedy's Pad 37B, the sixth Saturn I, biggest rocket in existence, carried a boilerplate, non-functional spacecraft. 

The mission marked firsts in several ways.  Whereas the previous five Saturns had been topped with Jupiter-C nosecones, SA-6 was the first to prove the actual Apollo structure.  Less auspiciously, the flight also marked the first malfunction of the Saturn rocket: 122 seconds into its mission, 24 seconds before planned cut-off, engine #8 prematurely shut down. 

But out of the jaws of failure came ultimate success.  The other engines continued to fire an additional two seconds, the four inboards shutting down shutting off 142 seconds into flight, the remaining three outboards going dark at Launch + 148.  Despite these compensations, AS-101 (the name for the spacecraft) was still flying "low and slow"; the second stage then ignited and compensated for the balky first stage, ultimately delivering the Apollo spacecraft almost perfectly into its planned orbit. 


That's Wernher von Braun in the middle; next to him, with the glasses, is George Mueller, who used to run the Pioneer lunar project at STL

Thus, the failure of engine #8 actually proved a blessing in disguise — we now know that the Saturn guidance system works quite nicely.  Moreover, given the excellent track record of the first stage's H-1 engines, I suspect the causes of the shutdown will be determined and remedied in short order.

AS-101 will be in orbit about one more day before it plunges into the atmosphere.  Like the first Gemini mission (last month), the spacecraft will not be recovered. 

SA-7/AS-102 will be a largely identical mission that will test the escape tower, the little rocket that will rescue Apollo astronauts in the event of a launch failure.  It is due to go up at the end of August.  Crewed spaceflights should happen as early as 1966!

No News is…

In other news, there isn't much news.  Since our last update, the Soviets launched Kosmoses 29 and 30 (April 25 and May 18), both of which landed just a week after launch, which suggests they were really spy satellites a la our Discoverer program.  Meanwhile, the United States Air Force lofted two birds of its own, a small one on April 27, and a big one on May 19.  I'd bet the first one was some a traditional film-return spy satellite (the kind that snaps photos in space and then sends the shots down to Earth for development in a little capsule).  As for the second, either it carries multiple canisters, or it's some kind of advanced system — maybe a real-time TV eye in orbit?

By the way, on April 21, I understand an Air Force rocket went boom, and the satellite it was carrying, a navigational Transit was on board.  That'd be no big deal…except this Transit was powered by the radioactive decay of plutonium-238.  I haven't heard much reporting on the subject, but I sure hope the flyboys are more careful next time!

The Soviets did launch Polyot-2 on April 12.  This is a special satellite that is able to change orbits.  That could mean that it's a precursor to the next Communist space vehicle (that's the thought advanced in Martin Caidin's recent novel, Marooned) or it could be a spacecraft designed to intercept missiles or other vehicles in space.  We won't know for a while, if ever.

Coming Attractions

As we head into the summer, it looks like things will remain pretty calm, unless the Russians pull another surprise out of their hats.  The only big event on the horizon is the launch of Ranger 7 in July.  After ten straight failures on the way to the Moon, I can't imagine the betting is particularly good for this flight.

But hope springs eternal…  See you then!

[April 10, 1964] Piercing the night (Gemini, Zond, Kosmos 28, and Explorer 9)

2 Comments


by Gideon Marcus

After what felt like a pause in the Space Race, things have now het up, and I'm getting excited abouting being on the NASA beat again.  To wit, both superpowers seem on the cusp of making a giant leap forward in the exploration of the great black unknown.

Two for the Price of One

It has been nearly a year since the Mercury program wrapped up.  Since then, NASA has been feverishly working on its Apollo lunar program, comprising the Saturn rocket, the three seat Command/Service Module, and the two seat Lunar Excursion Module.  We finally got a peek at a full scale mock-up of the last, and it's unlike any spacecraft I've ever seen before.

Even while NASA is progressing with Apollo, the space agency has also been proceeding with its Gemini two-seat spacecraft.  Gemini is a sort of bridge to Apollo, a direct successor to Mercury that will allow astronauts to perfect the techniques of orbital rendezvous and docking.  It is also likely that the Air Force will use Gemini to build a staffed space station and perhaps for other military purposes.

On April 8, 1964, the first Gemini soared into orbit atop a modified Titan II ICBM.  There was no one on board, but the flight was still an important one.  Using missiles borrowed from the Air Force is always a dicey proposition — they aren't designed to carry people, after all.  I am happy to report, however, that the new rocket did its job just about perfectly, delivering Gemini 1 to an orbit just slightly higher than planned.

The uncrewed spacecraft fell silent after its first orbit when the battery became exhausted, a planned occurrence.  In fact, no plans were ever made for recovery; the Titan second stage was left attached to the spacecraft, and holes were drilled into Gemini's heat shield to ensure it completely burns up when its orbit decays about two days from now.

This launch marks an important first step for Gemini.  The Titan II, a much simpler and stronger rocket than Mercury's Atlas, is now "man-rated."  It only remains for the capsule itself, to get the same certification.  That should happen with the Gemini 2 mission, planned for late this year. 

In any event, it's another "first" for America — we got the first two-seat ship into orbit!

Destination Unknown

The Soviet Union beat us to the moon in 1958 with Mechta, and they almost beat us to Mars last year, too (their craft went silent along the way).  Now, it looks like they're setting the stage for another deep space endeavor.

On April 2, 1964, the Russkies launched Zond 1 "for the purpose of developing a space system for distant interplanetary flights."  It left orbit, and TASS continues to report that Zond is functioning properly.  However, they are being extremely cagey about where the spacecraft is going.  Experts suggest that it might be a Venus probe based on its launch date and trajectory.  I suppose it could also be a long range mission with no planetary target like Pioneer 5 was.

Two days later, on April 4, the Soviets launched Kosmos 28, an orbital satellite "intended for the further exploration of outer space in accordance with the program announced by TASS March 16, 1962." 

Which is to say, probably a spy satellite like our own Discoverer program.

The Balloon Goes Down

Yesterday, we bade a fiery farewell to Explorer 9, the first of six planned 12-foot balloon satellites whose task is to measure the density of the top of Earth's atmosphere.  The satellite confirmed the daily bulge in the upper atmosphere caused by the sun's heating the air during the day, and it also verified the model of the region's temperature, established by prior satellites. 

Moreover, the satellite lasted long enough that its data could be compared to that of its identical successor, Explorer 19, which is still up there.

Explorer 9 was the first satellite to be launched by the Scout solid-fuel rocket and the first to be launched into orbit from Wallops Island in Virginia.  Ya did good, pal!

[February 5, 1964] That was the Month that Was (January's Space Roundup)

7 Comments


by Gideon Marcus

Another Lunar Black Eye

NASA's Project Ranger, which is basically a projectile aimed at the moon, has logged failure after failure since it started back in 1961.  The first ones in the series, Rangers 1 and 2, were just Earth-orbiting satellites designed to test the engineering and return scientific data.  Both of their missions were busts due to fault Agena second stages on their Atlas-Agena boosters.

Rangers 3 to 5 were bona-fide moon missions with giant pimples on their noses to do a bit of lunar geology (or selenology).  None of them completed their missions: Ranger 3 missed its target and was pointed the wrong way to boot, Ranger 4 hit the moon but was brain-dead from orbit onward, and Ranger 5 both missed and stopped working long before it got near the moon.

With five cracked eggs' experience to draw from, NASA tried again in January 30, 1964, with the first of the TV-armed Rangers, #6.  Aside from an odd voltage spike early on, Ranger 6 seemed to be working fine.  The spacecraft made a textbook-perfect flight all the way to its target, Mare Tranquillitas, impacting on schedule. 

But its TV camera never turned on.

I've been told that the fellow who announced the flight in real-time to the press has resigned from this duty, unable to go through such a harrowing experience again.  Who can blame him?  This is the sixth Ranger and the tenth failed (counting Pioneer Atlas Able) moon mission in a row.  On the other hand, and this is probably weak comfort at best, Ranger 6 did perform perfectly all the way until the end.  I'm sure Our American Cousin was a fine play, too.

There are three more third edition Rangers left to launch.  Let's hope at least one of them will be successful.  Right now, this program is making Project Vanguard look like an unalloyed success.

Stillborn Quintuplets

Speaking of Vanguard, on January 24, 1964, the Air Force launched another of its multi-satellite missions, attempting to orbit an unprecedented five spacecraft at once.  "Composite 1" comprised LOFTI 2, which was to study the ionosphere, Secor and Surcal, which would have helped the Army and Navy (respectively) calibrate their tracking radars, and Injun 2, a radiation satellite made by the University of Iowa (the same folks who discovered the Van Allen Belts.

Composite 1 also included SOLRAD (Solar Radiation) 4, and this is the Vanguard tie-in.  You see, the spottily successful Vanguard, which was America's first space project, was originally designed to study the sun's output of X-rays and ultraviolet light.  Unfortunately, the last of the Vanguards, number 3, was swamped with radiation from the Van Allen Belts, and its sun-pointed experiments were made useless.  End of story, right?

Well, SOLRAD 1, launched in 1960, was essentially Vanguard 4.  It was made by the same folks (the Naval Research Laboratory), used the same design, and carried the same experiments as Vanguard 3.  The only difference was purpose: the Navy wanted to know if there was a relation between solar flares and radio fade-outs (turns out yes). 

SOLRAD 2 was a dud thanks to a bad rocket, but SOLRAD 3 and Injun 1 returned good data.  The failure of SOLRAD 4 gives the program a .500 average — still pretty good to my mind.  I understand the Air Force will be trying again in a few months.

Five for five

How about some good news for a change?  For the fifth time in three years, the world's largest rocket took to the skies above Florida, January 29, 1964.  The Saturn I rocket, a precursor to the Saturn V behemoth that will take humans to Moon before this decade is out, has completed its run of test flights with a 100% success rate. 

I want that to sink in.  As far as I know, no rocket program has ever been 100% successful.  One would think that a booster as big as the Saturn should be more accident-prone than any other.  And yet, the trim cylindrical stack lifted off from Cape Kennedy, with both stages fueled for the first time, and placed its entire top half into orbit.  This gave Americans another first: world's largest satellite, weighing nearly ten tons!

The timing could not be better.  Apollo's future has been threatened a bit lately, with many in Congress seeking to reduce NASA's funding.  Some question whether there is even value in winning the race to the moon.  The outstanding success of the Saturn I will hopefully be a shot in the program's arm — and maybe for the related Project Ranger.

Now that testing of the rocket is complete, the Saturn I will go on to operational missions, flying full-scale examples of the Apollo spacecraft.  This will be the closest this first Saturn ever gets to the moon, however.  Huge as it is, it is not strong enough to launch Apollo to Earth's nearest neighbor.  It's not even strong enough to loft a fully-fueled Apollo!  But it's bigger brother, the Saturn IB, will be.  Expect its first flights in 1966 or so.

Can you hear me?

Last year, COMSAT corporation started selling publicly traded shares.  COMSAT was President Kennedy's compromise between a public and private satellite communications entity.  COMSAT has not yet developed any comsats, but that hasn't other entities are continuing to build experimental satellites toward the day when COMSAT birds begin to fly.

Relay 2

On January 21, 1964, the RCA-built Relay 2 joined its sister Relay 1, Ma-Bell-made Telstar 2, and the fixed-in-the-sky Syncom 2 in orbit.  With four active comsats in orbit (the kind that can retransmit broadcasts), we'll likely soon see transmissions bounce all over the globe.  The most exciting programming on the schedule?  This summer's Olympic games, live from Tokyo, Japan!

Echo 2

Just four days after the launch of Relay 2, NASA shot up Echo 2, a balloon-type passive reflector satellite — essentially a big mirror in space for bouncing signals.  It's larger than Echo 1, which is still in orbit, and should be visible from the ground when it zooms overhead.  I'm not sure why NASA bothered with this satellite given the sophistication of the active-repeater comsats.  I suspect there won't be many more.

Gavarit pa Ruskii?

Meanwhile, our Communist friends have not been entirely idle.  In addition to their increasing constellation of little Kosmos satellites, which may or may not be civilian in nature (probably not), the Soviets have created the twin "Elektron" orbiting laboratories.  The first two were launched on January 30 into separate orbits, their mission to explore the Van Allen Belts from both below and above!

It's the first time the Soviets have launched multiple satellites on a single rocket (we've been doing it since SOLRAD 1) and the first time since Sputnik 3 that a Russian mission has been verifiably civilian in nature. 

It's about time!

Space for Two

I'll wrap things up with a couple of pieces of news on the Gemini two-seat spacecraft, sort of a bridge between Projects Mercury and Apollo.  Firstly, it looks like the first uncrewed flight will happen as early as March, testing both the capsule and the Titan II rocket.  If this goes well, the first crewed flights may blast off as early as the end of this year.

Fingers crossed!

[December 21, 1963] Soaring and Plummeting (January 1964 Fantasy and Science Fiction)

5 Comments

[Time is running out to get your Worldcon membership!  Register here to be able to vote for the Hugos.]

The Balloon goes Up

It's been something of a dry patch for American space spectaculars, and with projects Gemini and Apollo both being delayed by technical and budgetary issues, it is no wonder that NASA is hungry for any positive news.  So you can excuse them for trumpeting the launch of Explorer 19 so loudly — even if the thing is just a big balloon.  How excited can anyone get about that?

As it turns out, plenty excited.

Explorer 19, launched December 19, 1963, is a spherical balloon painted with polka-dots (they keep the sun from making it too hot or cold), and what it does is measure the atmosphere as it circles the Earth.  Not with any active instruments, but just by moving.  All orbiting spacecraft have an ideal route, one determined by Newton's laws.  If there were no air at all up there, the satellite would just keep orbiting in the same path forever (though the Moon and the Sun exert their own influences).  But there is air up there.  To be sure, the "air" up above 600 kilometers in altitude is hardly deserving of the name — it's a harder vacuum than we can make on the ground!  Nevertheless, the stuff up there is denser than what is found in interplanetary space, and we can tell its density from the slow slip of Explorer 19 in its orbit. 

If we want to know what kind of science we'll get from Explorer 19, all we have to do is look to Explorer 9.  Launched two years ago, it is a virtual twin.  Both Explorers were launched from cheap, solid-fuel Scout rockets.  Both have tracking beacons that failed shortly after launch.  The only way to get any data from these missions is to track the satellites by sophisticated cameras.

Explorer 9 has already contributed immensely to our knowledge of Earth's upper atmosphere.  Thanks to constant photographic tracking of the satellite, scientists have seen the expansion of the atmosphere as it heats up during the day as well as shorter term heating from magnetic storms in the ionosphere.  As a result, we are getting a good idea of the "climate" on the other side of the atmosphere over a wide range of latitudes. 

This is not only useful as basic science; the folks who launch satellites now have a better idea how long their craft will last and the best orbits to shoot them into, saving money in the long run.  It is one of the many examples of how the exploration of space bears immediate fruit and also extended benefits.

And that's something to be excited about!

The other shoe drops

On the other hand, the January 1964 Fantasy and Science Fiction begins the year on the wrong foot.  It is yet another collection of substandard and overly affected tales (leavened by a few decent pieces that somehow manage to get through), something like what Analog has become, though to be fair, I'm really looking forward to Analog this month. 

But first…

Pacifist, by Mack Reynolds

The best piece of the month is Pacifist by the prolific, seasoned, and (on occasion) excellent Mack Reynolds.  On a world much like ours, but where the balance of power is held between the north and south hemispheres, an anti-war group determines that the only way to curb our species' bellicose tendencies is to frighten the war-wagers with violence.  But can you really quench fire with fire?

It works because of the writing, something Reynolds never has trouble with.  Four stars.

Starlight Rhapsody, by Zhuravleva Valentina

This curious piece, in which a young woman astronomer discerns intelligent signals being broadcast from the nearby star, Procyon, originated in the Soviet Union.  It was then translated into Esperanto, of all languages, and then found its way into English.  The result is…well, I'll let our Russian correspondent give us her thoughts:


by Margarita Mospanova

In Russian, Starlight Rhapsody is actually a very pretty story — melodic and full of poetry, literally and metaphorically. It’s fairly melancholy, with just a touch of underlying Soviet optimism, nothing too garish in this case. But the translation…

Man, the translation makes me want to tear my hair out. It’s awful. It misses entire paragraphs of text as well as actual poems in the beginning and in the end. And the prose itself in no way resembles the original. Hell, it’s as if the translator used some kind of computerized translation device and just removed the grammatical mistakes afterwards. I’m really disappointed because the original story is really unexpectedly good.


by Gideon Marcus

You can get a glimmer of the story's original strength even from the twice-butchered version that editor Davidson provides.  Thus, three dispirited stars.

The Follower, by Wenzell Brown

Witness the perfect match: A milquetoast who decides to make his mark on society by stalking someone, and a paranoiac who only finds satisfaction when someone really is after him.  But their game develops a twist when their twin psychoses create a third player combining the worst aspects of both.

Sounds intriguing, doesn't it?  If it were better done or more profound in its revelation, it might have been.  As is, it straddles the line between two and three stars, leaning toward the former.

The Tree of Time (Part 2 of 2), by Damon Knight

The conclusion of last month's adventure, in which a not-quite-man from the future is abducted from our time by frog people from his and then left to die in an experimental dimension ship.

After a reasonably thrilling beginning, the book reverts to what it was from the start — a pointless pastiche of the worst elements of science fiction's "Golden Age."  Deliberate or not, it's no less unreadable for it.

One star.  Feh.

Thaw and Serve, by Allen Kim Lang

Lang explores an interesting idea: hardened criminals are quick-frozen and deposited two centuries into the future.  It is the ultimate passing of the buck.  Turns out the future doesn't know what to do with them either, choosing to dump them in the wilds of Australia.  There, they fight it out for the televised amusement of the future-dwellers.

Written and plotted with a heavy hand, it's not one of Lang's better works.  In fact, the best thing about the story is the biographical preamble (Lang's middle name was given to him by Koreans during the war).

Two stars.

Nackles, by Curt Clark

"Curt Clark" (I have it on good authority that it's actually Donald Westlake) offers up the chilling story of the creation of a deity.  In this case, it's Santa Claus' dark shadow, the child-abducting "Nackles," who is caused to exist the same way as any other god — through widespread promulgation of belief.

Deeply unpleasant, but quite effective.  Three stars (four if this is your kind of thing).

Round and Round and …, by Isaac Asimov

At long last, I finally understand the concept of the "sidereal day," as well as the length of such days on other planets.  Thank you, Doctor A!  Four stars.

The Book of Elijah, by Edward Wellen

If you haven't read First and Second Kings (or as the uninitiated might call them, "One and Two Kings"), Elijah was a biblical prophet, passionate in his service of the Lord, who ascended to Heaven in flame and is due to return just before the End Times.  Ed Wellen, best known for his "funny" non-fact articles in Galaxy, writes about what happens to Elijah during his sojourn off Earth.

The Book is written in pseudo-King James style and is about as fun as reading the Bible, without any of the spiritual edification.  One star.

Appointment at Ten O'Clock, by Robert Lory

Last up, we have the tale of man with just ten minutes to live…over and over and over again.  Ten O'Clock has the beginning of an interesting concept and some deft writing, but it is short-circuited in execution.  It reads like the effort of a promising but neophyte author (which, in fact, it is — this is his second work).  Three stars.

This is what the once proud F&SF has been reduced to: a lousy Knight serial (shame, Damon!), a disappointing translation, some bad little pieces, and a couple of bright spots.  And Asimov's column, which I read, even if few others seem to.

Oh well.  I've already paid for the year.  Might as well see it through.

[August 29, 1963] Why we fly (August Space Round-up)

1 Comment


by Gideon Marcus

We've become a bit spoiled of late, what with space spectaculars occurring on a fairly regular basis.  So, I was not too surprised when a friend buttonholed me the other day and exclaimed, "When is the Space Race gonna get interesting again?"  After all, it's been a whole two months since the Vostok missions, three since the last Mercury mission, and even satellite launches have been few lately.

Oh ye of little faith.  The real work doesn't happen when the rockets go up, but after their payloads are aloft.  A lot happened in the arena of space this month — you just have to dig a little to learn about it.  Here are the exciting tidbits I gleaned (and the journos missed) in NASA's recent bulletins and broadcasts:

Bridging the Continents

Communication satellites continue to make our world a smaller place.  Syncom, built by Hughes and launched by NASA late last month, is the first comsat to have a 24-hour orbit.  From our perspective on the Earth's surface, it appears to do figure eights around one spot in the sky rather than circling the Earth.  This means Syncom can be a permanent relay station between the hemispheres.

It's already being used.  On August 4 the satellite allowed Nigerian journalists and folks from two U.S. services to exchange news stories as well as pictures of President Kennedy and Nigerian Governor General Dr. Nnamdi Zikiwe.  Five days later, voice and teletype was exchanged between Paso Robles, California and Lagos, Nigeria.  This 7,700 mile conversation represents the longest range real-time communication ever made.

And, on the 23rd, Syncom carried its first live telephone conversation — between President Kennedy and Nigerian Prime Minister Sir Abubaker Tafawa Balewa, as well as several other official conversations.  One has to wonder if the whole scheme wasn't hatched just so Jack could expand his pen pal list to West Africa…

More comsat news: RCA's Relay 1 is still alive and kicking, having been used in 930 wideband experiments, 409 narrowband transmissions, and 95 demos of TV and narrowband broadcasts.  And in a stunning imitation of Lazarus, AT&T's Telstar 2 came back on-line after having been silent since July 16.  I understand there will be an unprecedented experiment next month: NASA is going to use Relay and Syncom to bounce a message from Brazil to Africa.  Expect that kind of satellite ping-pong to become common in the future.

Finally, NASA's passive comsat, Echo 1, continues to be used for tests.  Come winter, it will be joined by Echo 2.  Because if there's anything space needs, it's more balloons.


First pass of Echo 1 satellite over the Goldstone

Predicting the Weather

Mariner 2, the Venus probe that encountered the Planet of Love last December, went silent early this year.  Yet its reams of data are still yielding discoveries.  During the spacecraft's long flight toward the sun, it took continuous measurements of the solar wind — that endless stream of charged particles cast off from the roiling fusion reactor of our nearest star.  These measurements were then compared to readings made on Earth and in orbit.  Scientists have now determined that the sun's radioactive breeze blows in gusts from 500 to 1350 kilometers per second, the bursts correlated with expansions in the solar corona.  When a particularly strong stream of electrons and protons, sizzling at a temperature of 500,000 degrees F., slams into the Earth's magnetic field, it causes disruptions in broadcasts and communications.

Closer to home, Explorer 12 soared far from Earth in its highly eccentric orbit, charting long-lived solar plasma streams in interplanetary space.  The satellite determined that these gouts of plasma caused geophysical disturbances more than twenty days after their creation.

One can imagine a constellation of satellites being deployed to provide solar system-wide space weather reports.  Not only would they help keep astronauts safe as they journeyed from planet to planet, but they'd also let radio operators on Earth know when to expect static in their broadcasts.

And speaking of weather forecasts, Tiros 6 and 7 continue to be our eyes in the sky, tirelessly shooting TV of Earth's weather.  They've already tracked the first hurricane of the season, Arlene.  Who knows how many lives and dollars they will save with their early warnings?

Previews of Coming Attractions

The ill-starred lunar probe, Ranger, has failed in all five of its missions.  In fact, NASA is 0 for 8 when it comes to moon shots since 1959.  Perhaps Ranger 6, set for launch around Thanksgiving, will break this losing streak.  It will be the first of the Block 3 Rangers, lacking the sky science experiments that flew on Rangers 1 and 2, and the big seismic impactors carried on Rangers 3-5.  The new Rangers will just shoot TV pictures of potential Apollo landing sites.  This sacrifice of science in deference to the human mission has not gone without protest, but given the dismal track record of the program, the labcoat crowd will have to take what they can get.

A full year after Ranger (hopefully) reaches the Moon, a pair of Mariners will set sail for Mars.  Unlike last year's Mariner 2, Mariners 3 and 4 will carry cameras to provide our first close-up view of the Red Planet.  Let's just hope neither of these upcoming probes meet the same fate as Russia's Mars 1, which died last March.

At some point in the mid-60s, even bigger Mariners will fly to the planets, carried by the big liquid oxygen "Centaur" second-stage.  The first successful test fire took place on August 17 just down the way from my house — at General Dynamics/Astronautics San Diego

And finally, another 271 space candidates applied to NASA this year.  They have been screened to 30, and out of them, 10-15 will be selected in late October to comprise the third group of astronauts.  None of them are women yet, but perhaps there will be some in time for Group Four.


Pilots Jerrie Cobb and Jane Hart testify before the Subcommittee of the House Committee on Science and Astronautics, July 1962.  That's an Atlas Centaur model next to them.

Who knows?  Maybe you'll be one of them!

[July 4, 1963] Down Under to the Worlds of Men (Woomera, Part 2)

4 Comments


by Ida Moya

There’s been some great (and terrible) science fiction writing in the journey last month. I so appreciate these reviews, which help me find interesting things to read, and bring me up to date on the preoccupations of science fiction authors. The illustrations from the magazines that The Traveler includes are so compelling in style and subject matter. I think that they are an under-appreciated art form that, perhaps, sometime in the future, could become appreciated and highly collectible.

A few months ago I wrote about my friend Mary Whitehead, who works as an Experimental Officer in Australia. She recently wrote me back with some corrections, that I will pass on to you, in order not to mar the historical record.

For example, I said that Mary lived at Woomera, which was not the case. I was conflating the rocket testing range with the place where most of the computing work got done. She actually lives near the Weapons Research Establishment (WRE), which is located in Salisbury, a small town about 15 miles north of the big city of Adelaide. Woomera Rocket Range is in the isolated outback another 300 miles north of that.

In 1949, Mary, who studied mathematics in college, got a job in the Bomb Ballistics Section of the WRE. At that time, Mary was the only professional woman at Salisbury. Her first work was to lead a team of female Computers. At first, they used mechanical calculators like the noisy Friden’s and then Marchant’s like we used at Los Alamos Scientific Laboratory.

In 1956 British company Elliott Brothers developed a custom-designed digital computer called WREDAC (Weapons Research Establishment Digital Automatic Computer) for WRE; one of but four digital computers in Australia at that time. This was a very sophisticated vacuum tube machine, a one off made a few years later than the ENIAC-style MANIAC we used at Los Alamos. In 1960 the WRE acquired the modular, somewhat mass-produced IBM 7090 mainframe computer, which is so valuable that they run it constantly, in three shifts.

Mary and some of her crew do go every once in a while to stay for a week at Woomera Village, next to the test range. She insisted that the Computers be able to observe the actual launches of rockets and missiles, and be trained in the operation of the data collection equipment — kinetheodolites, high-speed cine-cameras, radars, radio missile tracking systems, Doppler and telemetry reception equipment — in order to better interpret the results when they get back to Salisbury.


Two Computers wearing their army gear operate a kinetheodolite at Woomera around 1949.

Early on, it was quite a battle with the Range Superintendent to get her team to Woomera. He was concerned that it was an unsuitable and morally dangerous place for unattached young women. The compromise was that the women wear army gear – hat, khaki shirt and slacks, heavy brogues and leather jerkins for cold weather.

Back then, Woomera also did not have facilities for women, so they returned early from the range to have their showers from 4 to 5, before the men returned. The female Calculators also ate in the Officer’s Mess, so that they did not have to consort with the rougher men in the Other Ranks Mess. Today, though, the women working at Woomera have their own hostel and mess and no longer have to wear that army gear.

One part of Woomera range is a row of carefully calibrated cameras that take a series of photographs of a test launch. Her team also calibrates the cameras, which involves taking photographs of the starfield and getting the framing exactly right; a project that can take several weeks. Once calibrated, the tests commence and the launch photographs go back to the analysts, who use an overhead projector and other specialized equipment to translate each piece of film into location and time data. It’s really an amazingly detailed process involving a lot of cooperation. Now, what once took her team 4 weeks to calculate using Marchants, can be done in just a day on the IBM.

Another mistake in my article that Mary pointed out to me was that she had never visited Los Alamos Scientific Laboratory. When she visited America, she went to the Smithsonian Astrophysical Observatory to get a better star catalogue. She also went to Patrick Air Force Base in Florida, and then the Aberdeen Proving Ground in Washington State, where she consulted with some men who had devised the mathematics for using stars as background markers for measuring the trajectories. Mary also went to White Sands Missile Range in New Mexico, which must be where we met. She didn’t get to observe any missile tests at White Sands, but spoke with a man there who studies the refraction of light.

The project Mary is working on now is called Black Knight. It is a research ballistic missile, a test vehicle being used to get data to better design and build missiles, develop launch techniques, and learn how to handle such a big item. Mary’s group examines the Black Knight’s trajectory and re-entry into the atmosphere. So it’s important to get those measurements right, so these ballistic missiles can be better designed.

Mary, like me, is working for her government. In Australia and Britain, like the United States, there are careful bureaucracies that establish titles and pay rates. As a female Experimental Officer, Mary is paid the standard women’s rate of two-thirds of the male wage. Most of Mary’s female Computers are right out of school, and are expected to stay for only a few years, until they are married, when it is mandatory that they retire. Miss Mary Whitehead is not married, perhaps because of this system. Mary has even joined the Professional Officer’s Association to try to lobby for equal pay for equal work, but she is frustrated because the rest of the members are men so they don’t think too much of her appeals. Right now she trains new recruits, who start at the men’s base pay, which is more than she makes as an experienced officer. This Programmed Inequality that includes discarding of skilled Calculators and discouraging of skilled female technical workers is a great loss to the accuracy of this trajectory work in particular, and the development of computing technology in Australia and the United Kingdom in general.

I won’t tell you yet how much I make, but I too am stuck in a similarly unfair and enraging bureaucratic system. But, like me, Mary finds the work and constant learning so stimulating that it is almost worth it. Fortunately, the national push for equal rights among the races and sexes is beginning to change this awful standard. The 1960s is opening with turbulence; some people agitating for change, while other forces oppose this change, as the Traveler keeps pointing out. It’s a confusing time and hard to know what is real anymore. Perhaps a little science fiction and fantasy will ease this pain, and give us some insight into the potentials that we can build into our tomorrows.

[June 20, 1963] Crossing stars (the flights of Vostoks 5 and 6)

2 Comments


by Gideon Marcus

Gordo Cooper's 22-orbit flight in Faith 7 afforded America a rare monopoly on space news during the month of May.  Now, a new Soviet spectacular has put the West in the shade and ushered in a new era of spaceflight.

On June 14, Lt. Colonel Valery Bykosky zoomed into orbit atop the same type of rocket and in the same type of Vostok capsule that took his four predecessors to space.  Call signed "Hawk," he circled the Earth for just a hair shy of five days, beating the previous record set by Andrian Nikolayev in Vostok 3 by a few minutes.  Bykovsky conducted experiments, floated unstrapped from his seat a few times, ate, slept, and otherwise did the normal things one might expect of a cosmonaut.  He landed early yesterday morning.

That's not the exciting bit.

Two days after Hawk's flight began, he was joined by "Seagull" in Vostok 6.  As with the twin flights of Vostoks 3 and 4, Hawk and Seagull's trajectories were tailored to overlap so that the two spacecraft could get within hailing distance.  They shared radio transmissions and reported observing each other.  Vostok 6 landed around the same time as Vostok 5.  In most ways, the mission of Hawk and Seagull marked no new ground over the previous joint mission.

Except one: Vostok 6 was crewed by Valentina Tereshkova, a textile worker from Moscow.  She was the first woman and the first civilian in space. 

Let that settle in.  There are a lot of ramifications. 

When Project Mercury was established, NASA solicited applicants with a specific set of talents.  They had to be male military test pilots with thousands of hours of jet experience.  Seven were ultimately chosen, six of whom have flown.

Six Soviets have also flown.  Five were male military test pilots, but the sixth had never enlisted.  Tereshkova's closest relevant experience is that her hobbies included parachuting.  That the Soviet space program anticipated and insisted on including a civilian woman is significant.  Moreover, in her sole space flight, she logged more hours than all previous American astronauts combined.

You can call it a media stunt.  You can sneer that the Vostok capsules are bigger and more automated and therefore Tereshkova's role was limited to that of a passenger, not a pilot.  That's cold comfort, though.  The fact is, the Russians are thinking long-term.  They want to know how space affects men and women because they intend on not just conquering space but settling it.  Furthermore, they are demonstrating that Communism is an equal-opportunity business.  For all of our touting of democracy, America has no plans to let women join the space corps. 

So let's tally where we are in the "manned" space race as of June 1963.  The Americans have just finished the Mercury program, which had six flights, two of them suborbital.  The longest mission lasted a day-and-a-half.  There won't be another crewed flight until late '64, when the two-manned Gemini goes up.

Meanwhile, the Soviets launched six crewed Vostoks over roughly the same period.  But, they got there "fustest with the mostest," (Gagarin went up a month before Shepard), all of the flights were orbital, Vostok has an endurance at least three times that of Mercury, the Soviets mastered the art of double-launching, and, of course, their program is sophisticated enough to accommodate a non-pilot.  America may have been the first to break the sound barrier, but the Communists were the first to break the space gender barrier.

Our one consolation is that the near real-time appreciation of the Vostok flights was made possible by the existence of American communications satellites.  The TV transmissions from Vostoks 5 and 6 were relayed across the Atlantic via Telstar.  That's a pretty weak "yeah, but." 

Here's a better one.  Let's bring women into the astronaut corps.  In fact, there is already a reserve of thirteen woman pilots who have voluntarily subjected themselves to and passed the same test regimen as the Mercury 7.  Led by NASA consultant, Jerrie Cobb, they've been waiting in the wings for three years now.  They are eager and fit to fly — all they need is the green light from the space agency.  Given that the next class of astronauts will include civilians, there should be no barrier to letting one of these qualified women fly in Gemini and/or Apollo.

There shouldn't be…

[May 16, 1963] Going out with style (Gordo Cooper's Faith 7 Mercury flight)

8 Comments


by Gideon Marcus

Nearly six years ago, the Russians threw down the gauntlet with Sputnik.  Then they upped the ante with the orbit of Yuri Gagarin in April 1961.  It's hard to believe that, in just two years, America has not only answered the Soviet challenge but completed its first manned space program.

For those of us well-heeled in science fiction, the Mercury spacecraft is hardly impressive-looking.  Barely big enough to hold a person (and not a tall one, at that), it is little more than a second space suit with a heat shield and a retrorocket.  And yet, as a first step for America into outer space, its importance cannot be overstated.

For it was those first two Mercury-Redstone flights, Alan Shepard's and Gus Grissom's, which showed that one could survive both the crushing weight of acceleration and the exhilarating freedom from gravity, in close succession, no less.  John Glenn proved an astronaut could orbit repeatedly, and Scott Carpenter demonstrated that spacemen are unflappable when things don't go just right.  Wally Schirra doubled the mission length of his predecessors and perfected fuel conservation and landing accuracy. 

But it was this latest and last Mercury mission, flown by the youngest of the Mercury 7, 36-year old Gordo Cooper, that showed what an astronaut and his spacecraft could really do. 

The original Mercury configuration only allowed for short flights — no more than Schirra's six orbits (nine hours).  Cooper's mission was to get into the endurance range that the Soviet Vostok enjoys — a day and beyond.  That meant more batteries, more water, more oxygen, and more maneuvering fuel.  Some items had to be trimmed, weight being at a premium.  For instance, the largely irrelevant periscope was deleted, saving a precious 76 pounds.  The result was a stocked up, stripped down version of Mercury that Cooper called Faith 7.  NASA was not too happy with this choice, worried about the inevitable headline in the event of mission failure: America Loses Faith.

The flight of Faith was scheduled for April but weather and other considerations pushed the launch back to May.  Finally, early on the 14th, the astronaut suited up and entered his spacecraft.  After many hours of waiting, the flight was delayed until the next day.  There had been a problem with the Bermuda tracking radar.  It does one well to remember that an astronaut is just one of thousands of participants in any given mission, the failure of any one of whom can cause a scrub. 

All systems were go the next morning, however.  After a pleasant two-hour nap in his capsule while the countdown rolled and held without him, Cooper was then pressed into his seat with several times his weight come liftoff time, 8:04 A.M. Eastern Daylight Time.  Less than fifteen minutes later, he became the sixth American to enter Earth orbit.

The flight called for 22 orbits, with go/no-go opportunities after seven and seventeen.  Cooper was the first astronaut who got to sleep in orbit, though he spent the first hour of his designated slumber time snapping pictures of the Himalayas — and astonishing folks on the ground with his visual acuity.  According to the astronaut, he could pick out individual houses and vehicles from orbit. 

Orbit 17 came and went, and Cooper declared himself and his metal steed A-Okay to finish the mission.  But perhaps he had spoken too soon.  Come the 19th orbit, Faith 7 began to fall to pieces.  The cabin temperature rose, instrument readouts became erratic, and the automatic pilot failed completely.  As Cooper approached the end of the mission, he was confronted with a situation no one had ever had to face before: he would return himself from orbit manually.

Of course, that's why NASA hired test pilots for the job.  Cooper was delighted at the opportunity to show his stuff.  His aim and timing of his retrorocket fire was so precise that not only did he make it safely back to Earth, but he came down just a couple of miles from the recovery fleet off Midway Island.  Astronaut Cooper had flown longer and better than an American before him, ending is mission just before 4 P.M. EDT (11 AM local time).

Better still, Cooper had shared none of the deterioration of his spaceship.  Aside from a little pooling of blood in the legs, the astronaut was in good health.  Moreover, he experienced none of the disassociation from reality that psychologists worried would afflict long-term space travelers.  Faith 7 was, despite the breakdowns, a complete success.

In that success, Mercury has signed its own death warrant.  While some have clamored for a multi-day Mercury flight (particularly first astronaut Alan Shepard), the fact is, there just isn't much more to learn with such a minimal craft.  The longer, more involved missions are going to need a more sophisticated spacecraft.  A two-person ship with the ability to maneuver and dock.

It's in development right now, and it's called Gemini.  It flies next year.

[Apr. 29, 1963] When a malfunction isn't (the flight of Saturn I #4 and other space tidbits)

2 Comments


by Gideon Marcus

Baby's first step… Take Four

Out in Huntsville, Alabama, Von Braun's team is busy making the biggest rockets ever conceived.  The three-stage Saturn V, with five of the biggest engines ever made, will take people to the Moon before the decade is out.  But NASA's is justifiably leery of running before walking.  Moreover, there is use for a yet smaller (but still huge!) rocket for orbital Apollo testing and, also, practice building and launching Saturn rocket components.

Enter the two-stage Saturn I, whose first stage has eight engines, like the Nova, but they are much smaller.  Still, altogether, they produce 1.5 million pounds of thrust — that's six times more than the Atlas that will put Gordo Cooper's Mercury into orbit next month.  The Saturn I's second stage will likely also be the third stage on the Saturn V.

The Saturn I has had the most successful testing program of any rocket that I know of.  It's also one of the most maddeningly slow testing programs (I'm not really complaining — methodical is good, and it's not as if Apollo's ready to fly, anyway). 

The fourth in the series lifted off March 28, and they still aren't fueling the second stage.  They've essentially all been tests of stage #1.  This particular test was interesting because they shut off one of the engines on purpose during the flight to see if the other engines could compensate for the loss.  SA-4 continued to work perfectly, zooming to an altitude of 129 kilometers.

SA-4 was the last of the first-stage-only tests.  Henceforth, we'll get to see what the full stack can do. 

A breath of very thin fresh air

We tend to ignore most of the atmosphere.  After all, the air we breathe and most of the weather are confined to the first few kilometers above the Earth.  But the upper regions of the atmosphere contain the ozone layer, which shields us from deadly radiations; the ionosphere, which bounces radio waves back to Earth; beautiful and mysterious noctilucent clouds, only visible after sunset; and of course, spacecraft have to travel through it on their way up and down.  Knowing the makeup of our atmosphere gives us clues to understand climate, the history of the Earth, the interaction of our planet and the sun, and much more.

And yet, aside from the TIROS weather satellites, which only study the lowest level of the atmosphere, there has never been a dedicated atmospheric study satellite.  Sure, we've launched probes to detect radiation and charged particles and the Earth's magnetosphere.  Some have investigated the propagation of radio waves through the ionosphere.  But none have gone into space just to sample the thin air of the upper atmosphere and find out what's up there and how much.

Until now. 

Explorer 17 is a big, sputnik-looking ball loaded with a bunch of pressure gauges and other instruments.  Its sole purpose is to measure the the pressure and make-up of the upper atmosphere, from about 170 kilometers up. 

Launched on April 3rd, in its first few days of operation, the probe has more than tripled all previous measurements of neutral gases in Earth's upper atmosphere to date.  For instance, the satellite has discovered that the earth is surrounded by a belt of neutral helium at an altitude of from 250 to 1000 miles, a belt no one was sure it existed.  We suspected it, of course — helium, produced in the Earth's crust by the natural radioactive decay of heavy elements, is very light.  Just as helium balloons go up and up, free helium's normal fate is to eventually escape Earth's gravitational influence, leaving behind the heavier gasses. 

This is the first time this hypothesis had a chance to be proven, and by measuring the density of this helium, we should be able to get an idea of how much helium is generated by the Earth each year.  This, in turn, will tell us something about how much radioactive material is left on Earth.  Isn't that neat?  We send a probe far up into space to learn more about what's going on down here.  Your tax dollar hard at work.

The Cosmos opening up for Kosmos

Pop quiz — what did the Soviets accomplish last year in the Space Race?  Right.  The Soviets made big news with the flashy dual mission of Vostoks 3 and 4.  Anything else?  Can you recall a single space accomplishment for the Communists?  In 1962, the United States launched Telstar, the Orbiting Solar Observatory (OSO), three Explorer science probes, three Ranger moon probes, Mariner 2 to Venus, and a couple dozen military satellites, not to mention the orbital Mercury flights of John Glenn, Scott Carpenter, and Wally Schirra.

This year is a different story.  We Americans haven't slackened our pace, but the Russians have finally picked up theirs.  They've got a probe on its way to Mars, as well as a new series of satellites called Kosmos.  This month, they launched three, getting up to Kosmos 16.  They are touted as science satellites, but there has been precious little data from them made public or that's worked its way into scientific papers.  This suggests that the Kosmos program is really a civilian front for a military program.  That's the fundamental difference between the Western and Eastern space efforts.  While the American military takes up its share of the national space budget, we still make sure there's room for pure science.  The Soviets have chosen between guns and science in favor of the former (though, to be fair, if we could only afford one option, would we have made the same choice?)

So why did it take so long for the Soviets to get into the groove after having such a seemingly commanding lead in the Space Race?  And just what are the Kosmos satellites really doing up there? 

According to a NASA scientist, the lack of announced flights doesn't mean the Russians didn't try.  Our Communist friends are notorious for talking only about their successes.  In fact, the Soviets were trying a new four-stage version of the booster that launched Sputnik and Vostok, and the fourth stage kept failing.  There might have been a few failed moon missions in there, too, that we never heard about.  We probably only learned about Luna 4, launched April 2, because it took off just fine — it just missed its target (the Soviet reporting after lunar flyby was notably subdued). 

As for what Kosmos is, Aviation Weekly and Space Report suggests the series is really two types of satellites based on weight and orbital trajectory.  One is a small class of probe that stays up for months.  They could be akin to our Explorers, but again, they don't produce science (whereas ours have revolutionized our knowledge of near-Earth space).  More likely, they are engineering satellites designed to test various components for future missions: communications, cameras, navigation.

The other class is big — as big as the manned Vostoks.  They only fly a few days, too, and their orbits cover most of the globe.  These could be unmanned tests of the next generation of Soviet manned spacecraft.  But they also could be repurposed Vostoks designed to conduct spy missions.  Perhaps the Soviet Union is sending up cosmonauts with camera in hand (as we have done on the Mercury missions).  Sure, it's more expensive than our Discoverer spy sats, but everything's free in a command economy, right?

In any event, the world once again has two active space superpowers.  What happens next is anyone's guess…

[Mar. 30, 1963] Mercury waltzes Matilda (the tracking and research station at Woomera, Australia)

2 Comments


by Ida Moya

I’m back from a whirlwind of helping the data analysts at Los Alamos get their FORTRAN formulas running on that balky old IBM Stretch computer. I can see why IBM only made 8 of these things. It is miraculous to have a computer that can fit into a single room, but this stretch (pardon the pun) in computing technology still averages only 17 hours uptime a day — and that’s also a stretch (no more, I promise).

When it breaks, this swarm of white-coated men in ties comes in and fusses around with it with a bunch of special tools, as well as the set of ALDs (Automated Logic Diagrams) that come with every IBM computer. The way those diagrams are produced and updated with punch cards and special line printers is an amazing story, but for another time.

Although we at Los Alamos Scientific Laboratory can comfort ourselves that the Stretch is the fastest computer in the world, I’m still envious of the institutions that have the better-engineered IBM 7090 computers. These are being used for calculations for the exciting Mercury program.


IBM 7090 at the Weapons Research Establishment's headquarters at Salisbury, on the northern outskirts of Adelaide in South Australia.

The Mercury spaceships do not have a computer on board – computers are far too heavy – so for figuring out how to re-enter the earth’s atmosphere the astronauts rely on computations sent by radio from the pair of IBM 7090 computers at the Mercury Control Station at Cape Canaveral. It’s an incredible amount of faith to put in one site, so Mercury control has those two redundant IBM computers, plus another set of computers in New Jersey. A third computer gathering information from the flight is on the other side of the globe — in Adelaide processing tracking data collected at at Weapons Research Establishment in Woomera, Australia. There is also another control center at Muchea, in Western Australia.


Control room of the astronaut tracking station at Muchea in Western Australia, part of US Project Mercury

A lot of people haven’t heard of Woomera, so let me tell you a little bit about it. At Woomera, more is being done than track Mercury astronauts. This part's an open secret, but the Brits and the Aussies are working together there on testing (or doing “trials” as they say) on rockets, missiles, and even atomic weapons. That's why they built this testing range in the middle of nowhere, in the outback of Australia.


Woomera Research Establishment Officer’s mess

A few years ago we had a visit from Bill Boswell, the Woomera director, along with a team from Maths Services, and Mary Whitehead, the leader of the Planning and Data Analysis Group. They were visiting various computer installations at Point Mugu, White Sands, and Cape Canaveral. These are all larger-than life place-names, but they really just represent groups of men and women madly making observations, coding the photographs in a way the computer can understand, and using these results to steer the manned spaceships. Mary and I had time to talk about more prosaic things, like her new apartment (or “flat” as they call it down under) in Woomera village, and the troubles of living so far from civilization.


Mary’s new flat at Woomera

Woomera reminds me a lot of Los Alamos. It is a similar purpose-built town, isolated from the surrounding population by remoteness and security. Entire families live there, with houses, apartments, and schools for the kids. There are clubs and mess halls; a bowling alley and community grocery store. The store sells just canned and packaged food; if you want something fresh the closest produce is 50 miles away. The planners made a lot of efforts to plant trees, most of which failed. Honestly, it sounds awful to me. I love the "Land of Enchantment" (New Mexico), where things actually grow. The two science towns also have odd mixed populations – for Los Alamos, it is the influx of American and foreign scientists, local Hispanos, and the San Ildefonso tribe. In Woomera, it is the influx of British scientists, local Aussies, and the aboriginal people. Personally I think Los Alamos does a better job of integrating the native population.


Community store in Woomera

There’s something about space that is so exciting. Space has it all: exploration, discovery, danger, and destiny. There’s so much more to it than my dry work of computers, trajectory calculations, and strangely named groups that I am so mired in. That’s why I am so excited to find science fiction and Galactic Journey’s reviews, which is opening my mind to our real future in space that this work makes possible.
