Out, damn spot!

A couple of weeks ago, Victoria Silverwolf offered us a tidbit on the latest solar eclipse.  I've since read a bit more about the scientific side of things and thought I'd share what I've learned with you.

It was the first total solar eclipse to be seen over heavily populated areas of U.S. since 1925, greeted by millions of viewers who crowded the beaches, towns, and islands where viewing was most favorable.  The eclipse cut a nearly 100 mile wide swath through Mexico, Florida, Georgia, the Carolinas, Virginia, and Nantucket Island, Mass.  It was 96% total in New York City and 95% in the nation's capital.

Below the image, the headline reads Partial Eclipse as seen in North County.  The caption reads The partial eclipse seen by teh North County Saturday morning is superimposed over the Palomar College Dome Gym in this collage by staff photographer Dan Rios.  The maximum ecliplse in this area was roughly 30 per cent at 9am as shown in the fourth sun from the left.  Seven states were treated to a full eclipse.

But ground viewing was only the beginning.  NASA employed a flotilla of platforms to observe the eclipse from an unprecedented variety of vantages.  A barrage of sounding rockets (suborbital science probes) were launched during the eclipse to take measurements of the Earth's atmosphere and ionosphere.

In space, radio signals from Mars probe Mariner 6, currently on the far side of Sun, were measured to determine how the eclipse affected communications and to study changes in charged particles in earth’s atmosphere.

Two Orbiting Solar Observatories, #5 and #6, pointed their instruments at the Sun to gather data on the solar atmosphere, while Advanced Test Satellite #3 took pictures of the Moon's shadow on the Earth from more than 20,000 miles above the surface.  Three American-Canadian satellites, Alouette 1, Alouette 2, and Isis 1, all examined the change the eclipse caused in the Earth's ionosphere.

Earthside telescopes got into the mix, too: Observers from three universities and four NASA centers at sites in Virginia and Mexico not only got great shots of the solar corona, but also of faint comets normally washed out in the glare of the Sun.

I can't imagine anyone in 1925 but maybe Hugo Gernsback could have foreseen how much attention, and from how many angles such attention would be applied, during the 1970 eclipse.  It's just one more example of how science fiction has become science.

Waiting for the dawn

The last two months of The Magazine of Fantasy and Science Fiction weren't too hot.  Does the latest issue mark a return of the light or continued darkness?  Let's find out…

In just three weeks, on 15 March, World Expo 1970 will open in Osaka, Japan, the first time that a world’s fair has been held in Asia. This event is intended to welcome the world to Japan as a celebration of the massive strides the country has made in national re-development since the War. One of Japan’s latest achievements took place only two weeks ago – the launch of its first satellite!

Yes, Japan has now joined the Space Club, as the first Asian nation to put a satellite into orbit. Not only that, but Japan becomes only the fourth country to have launched its own satellite using a home-grown launch vehicle!

The small satellite, named Ohsumi for the peninsula on the island of Kyushu from which it was launched, was lofted on a four-stage Lambda 4S solid-fuel rocket on 11 February. The launch site, known as the Kagoshima Space Centre, is located in Kagoshima Prefecture at the southernmost end of the island of Kyushu, near Uchinoura. It’s been the home of Japan’s space launch activities since 1962.

At this point, you are probably thinking that you’ve never heard anything before about Japanese space activity – and that would be no surprise, as the Western media, unfortunately, pays little attention to Asian nations outside of reporting on conflicts and (supposed) Communist threats. So you might be surprised to know that Japanese interest in space exploration goes back to the mid-1950s.

Recently, The Traveller covered the launch of the TIROS-M weather satellite, noting that the rocket’s payload also included a small Australian-made ham radio satellite, OSCAR-5 (Orbiting Satellite Carrying Amateur Radio), also known as OSCAR-A.

It was exciting to be in “Mission Control” at the University of Melbourne when the satellite was launched in the evening (Australian time) on 23 January. You should have heard the cheers! After all, Australis-OSCAR-5 (AO-5), as we call it, is Australia’s second satellite. It’s also the first amateur radio satellite built outside the United States and the first OSCAR satellite constructed by university students – in this case, members of the Melbourne University Astronautical Society (MUAS).

Radio Hams and Satellite Trackers

Commencing in 1961, the first OSCAR satellite was constructed by a group of American amateur radio enthusiasts. Cross-over membership between MUAS and the Melbourne University Radio Club (MURC) encouraged the students to begin tracking OSCAR satellites, moving quickly on to tracking and receiving signals from many other US and Soviet satellites.

One of MUAS’ achievements was the first regular reception in Australia of images from TIROS and Nimbus meteorological satellites. By 1964, they were supplying satellite weather images daily to the Bureau of Meteorology, before it established its own receiving facilities.

"How Do We Build a Satellite?"

After tracking OSCARs 3 and 4 in 1965, the MUAS students decided to try building their own satellite. “No one told us it couldn’t be done, and we were too naive to realise how complex it would be to get the satellite launched!”, an AO-5 team member told me at the launch party. MUAS decided to build a small ‘beacon’ satellite which would transmit telemetry data back to Earth on fixed frequencies.

Even before Australia’s first-launched satellite, WRESAT-1, was on the drawing board, the Australis satellite project commenced in March 1966. Volunteers from MUAS, MURC and university staff worked together to design and build the satellite, with technical and financial assistance from the Wireless Institute of Australia and a tiny budget of $600. The Australian NASA representative also gave the project invaluable support. The students acquired electronic and other components through donations from suppliers where possible: the springs used to push the satellite away from the launcher were generously made by a mattress manufacturer in Melbourne. Any other expenses came out of their own pockets!

AO-5 is a fantastic example of Aussie ‘make-do’ ingenuity. A flexible steel measuring tape from a hardware shop was cut up to make the antennae. The oven at the share house of one team member served to test the satellite’s heat tolerance, and a freezer in the university's glaciology lab was unofficially used for the cold soak. Copper circuit boards were etched with a technique using nail varnish, and a rifle-sight was used to help tune the antennae! Various components, including the transmitters and command system, were flight-tested on the university’s high altitude research balloon flights.

A Long Wait for Launch

Australis was completed and delivered to Project OSCAR headquarters in June 1967, well before WRESAT’s launch in November that year. Unfortunately, AO-5 then had to wait a few years for a launch to be arranged by the Amateur Radio Satellite Corporation (AMSAT), which now operates the OSCAR project. However, it is surely appropriate that, as OSCAR-5, it finally made it into orbit with a weather satellite.

After launch from Vandenberg Air Force Base, AO-5 was placed into a 115-minute orbit, varying in altitude between 880 – 910 miles. This means it will be in orbit for hundreds of years – unlike the short-lived WRESAT.

In Orbit at Last!

Battery-powered, Australis-OSCAR-5 weighs only 39 pounds and carries two transmitters, beaming out the same telemetry signal on the two-metre and 10-metre amateur radio bands. Its telemetry system is sophisticated but designed for simple decoding without expensive equipment. The start of a telemetry sequence is indicated by the letters HI in Morse code, followed by data on battery voltage, current, and the temperature of the satellite at two points as well as information on the satellite's orientation in space from three horizon sensors.

AO-5 includes the first use in an amateur satellite of innovations such as a passive magnetic attitude stabilisation system (which helps reduce signal fading), and a command system to switch it on and off to conserve power. Observations are recorded on special standardised reporting forms that are suitable for computer analysis.

Just 66 minutes after launch, the first signal was detected in Madagascar and soon other hams reported receiving both the two and 10-metre signals on the satellite's first orbit. At “Mission Control” in Melbourne, we were thrilled when MURC members managed to pick up the satellite’s signals!  By the end of Australis’ first day of operation, AMSAT headquarters had already received more than 100 tracking, telemetry and reception reports.

There was plenty of interest here in Australia.

The two-metre signal failed on 14 February, but the 10-metre transmission continues for now. How much longer AO-5’s batteries will last is anybody’s guess, but the satellite has proven itself to be a successful demonstration of the MUAS students’ technical capabilities, and the team is already contemplating a more advanced follow-on satellite project.

[January 4, 1970] Word for the Day: ARPANET


by Victoria Lucas

OK, kiddies, the word for today is ARPANET. Well, yes, good point, it’s not a word, is it? It’s an acronym jammed into an abbreviation. But a juicy one.

I found out what it means because Mel (my husband) and I have these friends in Orinda, California (a town east of Berkeley, nice place). Sharon is more of a stand-up comedian than a housewife, who uses her housewifery–-and sometimes herself–-as the butt of her jokes. Dick Karpinski is a fuzzy bear of a man who is the first computer programmer I ever met. We don’t get to their place too often, since it’s off our beaten track between SF/Berkeley and Fortuna that we usually run on the weekends and holidays (or when neither of us has an active temp job in the Eureka area).

Richard Karpinski works for the University of California at San Francisco, supporting users of the IBM 360 and other tasks

At a recent visit, Dick was quite excited, and Sharon was complaining about her “three years of back ironing.” I don’t have much to say about the ironing, but once Dick had explained to me the reason for his excitement I admitted to some buoyancy myself. I wonder how you will feel about it.

With its initial transmission in October last year, ARPANET (Advanced Research Projects Agency Network) is the first large-scale, general-purpose computer network to link different kinds of computers together without a direct connection. Not only that, but different kinds of networks are coming online following this one. But who cares, right? I mean who of us has ever even seen a computer?

FAR OUT!

Up to now you could only connect the same kind of computers, and then only by special-purpose cables and outlets in the same building, unless you could connect your computer to a "modem” (modulator-de-modulator) that converts digital (computer talk) to analog (telephone signaling) and back again when connected to your telephone line. The same protocols and hardware can connect a computer to “terminals,” boxes that can interact with a computer but do not have the smarts to actually process data. Multiple people could use the same computer at the same time (the miracle of "time sharing" that Ida Moya talked about a few years back, but again, only at the same site or by telephone. No matter what, connections were direct: point to point and dedicated. If you wanted to interact with another computer, you had to go to another terminal hooked up, directly or via modem, to the new machine.

But what if you wanted to access multiple other computers from a single terminal? What if you wanted your computer to talk to another, farflung computer of a different make (ie connect an IBM to a CDC?) Here’s where Dick had to bring out his yellow pad and start writing and drawing.

Dick draws a box on his pad. “One computer, right?”* he says. “And here’s another” as he draws another box to make #2. Now you could connect a single terminal to any number of computers using a newly developed "protocol" for connection. (A protocol, drawn as lines from that word toward the boxes, is a set of rules or instructions about how to do something, and it’s above a program, which is more of a detailed list of steps to use when doing something.) Rather than using specific hardware, the protocol allows computers to "speak" a common language, over phone-lines lines… regardless of computer make or location!

As Dick, the “Nitpicker Extraordinaire,” might have written at the top of his pad (I’m a little fuzzy about how the conversation progressed), the first set of computers involved in the evolution of this network would have belonged to the US Department of Defense as part of its Advanced Research Projects Agency (ARPA), an almost direct result of the success of Sputnik. When NASA (National Aeronautics and Space Agency) was formed in 1958, most of ARPA’s projects and funding were moved to that group. That left ARPA with high-risk or far-out projects, such as computer networking. I can't tell you which computers are involved, nor the details of the protocol (even if I understood them) because they're classified. The main reason for the ARPA network is to test the survivability of communications in the event of a nuclear war. Because if one big computer is destroyed, someone could just use their terminal to contact a different one to complete a process.

Talk to any computer anywhere, without a telephone

While this exciting technology is limited to the ARPA for the moment, technology tends to spread to civilians eventually. Just think about it! The ARPA network and others like it will make it possible to distribute programs and data widely without printing it out and mailing it. As long as a computer can talk back, you can get and send data from and to it. Even more amazing, the initial transmission speeds showed that messages were being sent to a place 350 miles away 500 times faster than local data was traveling before. It was so fast that the initial speed caused a system crash, followed by a rebuild to handle the velocity, all during the very first transmission. It's not faster than light, but it's a darn sight better than having a computer operator working on far-out national research projects for ARPA fall asleep on his or her keyboard waiting for an answer.

What miracles could you work with a fast, smart, terminal that could connect to any computer in the world? Now that’s exciting!

*To Dick’s other friends. Yes, I know Dick, but I don’t remember any specific conversation like this. Any mistakes or misrepresentations are my responsibility.

Being #2… stinks

On the scene at the launch of Apollo 12, President Nixon assured the NASA technicians that America was #1 in space, and that it wasn't just jingoism—it was true!

Well, even a stopped clock, etc.  In fact, all accounts suggest the Soviet space program had some serious setbacks last year, the results of which will be felt through at least to 1971.  Schedules got shifted as large rockets were earmarked for purely military service in response to the escalating (now calmed) Sino-Soviet crisis.  But the biggest issue was reported in Aviation Weekly last month: apparently, the Soviets lost a Saturn-class booster on the launch pad before liftoff last summer.  I hadn't even heard that such a thing was in development!  The rocket's loss has set back the USSR's manned space program by at least a year, resulting in tepid non-achievements like their recent triple Soyuz mission rather than the construction of a space station or a trip to the Moon.

A rocket being launched into space.
This is actually the rocket from the Soviet film The Sky Calls (American title: Battle Beyond the Sun)

It didn't help that the Soyuz pads were occupied during the summer as the Soviets tried to match our lunar efforts.  It may well be that their Saturn was rushed to service too soon, and similar gun-jumping may have caused the loss of the Luna 15 sample-return mission.

Speaking of which, in September, the Soviets launched Kosmos 300 and 305.  Both of them were heavy satellites that went into the orbit usually used for lunar Zond missions.  And then they reentered shortly thereafter…in pieces.  It's not certain if these were to be circumlunar flights or retries of Luna 15.  Either way, they didn't work out, either.

Meanwhile, the Apollo mission moves blithely along.  Apollo 13 will go to the Moon next March to Fra Mauro, a landing site photographically scouted out by the Apollo 12 folks.  This chapter of the Space Race is well and truly over, won by the forces of democracy championed by such luminaries as Spiro Agnew.

That's a good rock

Speaking of Apollo 12, you may recall earlier this month I talked about analysis of the Moon rocks brought back by Apollo 11.  A similar report has come out about the rocks brought back by Conrad and Bean.  Dr. Oliver A. Schaeffer of New York State Univ. at Stony Brook says they are only 2.2 to 2.5 billion years old—1-2 billion years younger than the Armstrong and Aldrin's samples.  This means some kind of surface activity was ongoing on the comparatively quiet Moon—meteorite strikes and/or vulcanism, we don't know yet.


NASA astronaut Charles "Pete" Conrad, commander of the Apollo 12 mission, holds two moon rocks he and Alan Bean brought back to Earth.  Taken last month at Manned Spacecraft Center's Lunar Receiving Laboratory.

Also, Dr. S. Ross Taylor of Australian National Univ. says the Apollo 12 samples contain about half the titanium as the Apollo 11 rocks and also more nickel, though otherwise, their chemistry is similar.  Thus, the Moon is far from homogeneous, and we have just scratched the surface (so to speak) of the mystery that is the Moon.  As we get more samples from more sites, a better picture will come together, but it will undoubtedly take time; imagine trying to contemplate all of Earth's geologic diversity from just two short digs?

[December 14, 1969] West Germany Joins the Space Race: The Azur Mission


by Cora Buhlert

One Large Step

Last month, in the early hours of November 8 to be precise, West Germany joined the ranks of spacefaring nations and became the eighth country to put a satellite in orbit with the launch of Azur, also known as German Research Satellite GSR A, to return radiation data from its vantage hundreds of kilometers above the Earth.

Cheers erupted at the newly established German Space Operations Center in Oberpfaffenhofen, Bavaria, when footage of Azur taking off into orbit aboard a NASA Scout-B rocket from Vandenberg Air Force Base in California was broadcast on the great viewscreen in the control center. The fact that the launch had been delayed due to a malfunction and fuel leak during a test countdown was forgotten. And even more cheers erupted, when a ground station in Johannesburg, South Africa, made the first contact with Azur.

A Massive Project

Azur weighs 71 kilograms and carries the hefty price tag of eighty million Deutschmarks, which includes the establishment of the German Space Operations Center in Oberpfaffenhofen. The satellite is the result of years of development and cooperation between various companies and agencies. On the administrative side, the West German Ministry of Science, the Deutsche Forschungs- und Versuchsanstalt für Luft- und Raumfahrt (German research and testing agency for air and space travel) and the Gesellschaft für Weltraumforschung (Society for space research) and were all involved, as was NASA who supplied the Scout-B rocket that carried Azur into orbit. The experiments and payload were developed by the Max-Planck-Institut für Aeronomie (Max Planck Institute for aeronomics) and the actual satellite was built by a consortium of West German aerospace companies including Messerschmitt-Bölkow-Blohm GmbH and ERNO Raumfahrttechnik GmbH.

The latter is of particular interest to me, because ERNO Raumfahrttechnik GmbH is based in my hometown of Bremen, a city with a long and illustrious history of aeronautics engineering. That is, the ERNO headquarters are in Bremen, but actual production facilities, where parts of Azur were manufactured, are located in an industrial park in Stuhrbaum, only some four kilometers from where I live. As a matter of fact, I have often driven past the drab ERNO production halls, which – very likely intentionally – give little indication from the outside of the cutting edge technology being developed and manufactured within.

The Future is Bright… and Blue

Putting a satellite into orbit is a triumph in itself, but Azur also has a research mission beyond purely proving that West Germany can do it. Out of hundreds of suggestions, the Max-Planck-Institut für Aeronomie in the small town of Katlenburg-Lindau selected seven experiments, which are supposed to research cosmic radiation, solar particles and their interaction with the magnetosphere, the Van Allen belt and the aurora borealis. That's also the reason why Azur's orbit crosses the polar regions at an inclination of 103 degrees at a height of between 368 and 1445 kilometres.

One issue was that the satellite designs suggested by NASA proved to be unsuitable for Azur, since its mission would take it across the polar regions, where the external solar panels with a fixed setting would not be able to supply sufficient power to the satellite. So German engineers came up with the solution to cover the entire exterior of the satellite with more than five thousand solar cells. The shimmering blue colour of these solar cells also gave the satellite its name: Azur.

Azur is being fitted to the Scout-B rocket that will carry it into orbit at Vandenberg Air Force Base in California. The distinctive blue colour that gave the satellite its name is clearly visible.

Setbacks and Mysteries

The excitement about the successful launch of Azur was somewhat dampened when it turned out that the settings of many of the scientific instruments aboard had been changed and needed to be reset. The team at the control center in Oberpfaffenhofen reset the all the instruments to their correct parameters, only to find them changed again after every circumnavigation.

There were suspicions that a hostile power, most likely the Soviets, had somehow managed to gain access to Azur and were messing with the settings. The solution to the mystery, however, was far from a James Bond movie, even though espionage did turn out to be at fault, albeit unwittingly. For the control center team noticed that the setting changes always happened whenever Azur was above the US west coast and Alaska, areas where there are a lot of radar stations spying on the USSR. Azur picked up the signals broadcast by those radar stations and misinterpreted them as commands. Requiring a command to be repeated two or even three times before an order is executed would have prevented this issue. However, NASA specialists had assured the West German Azur developers that this wasn't necessary.

Another setback occurred last week, when the onboard magnetic data storage tape recorder failed, so that the data collected by Azur can only be broadcast in real time now. Luckily, a network of German and foreign ground stations means that eighty percent of the data can be received anyway, so the failure of the onboard recorder is only a minor inconvenience.

Space Research in East and West Germany

Azur is projected to collect and broadcast data for at least one year. And though Azur was West Germany's first step into space, it won't be the last, for the next West German satellite, DIAL-WIKA is expected to launch in only four months, this time via a French Diamant-B rocket in cooperation with the Centre national d’études spatiales.

Meanwhile, on the other side of the iron curtain, East Germany is a partner in the Soviet Interkosmos program and supplied several of the instruments aboard the Interkosmos-1 research satellite which was launched in October.

"Space is the final frontier", as the opening narration of a popular American TV-show that has yet to air in Germany puts it. Both East and West Germany have taken their first tentative steps across that final frontier. As we enter the new decade, more steps will follow and maybe we will even see a German astronaut (or cosmonaut) in space one day.

With the Apollo missions taking so much of our attention (there were four flights this year), it is understandable that unmanned missions and science have gotten short shrift.  I'm going to try to address this oversight now.

Far out!

Do you remember Pioneer 6 (launched Dec. 16, 1965) and Pioneer 7 (launched Aug. 17, 1966)?  They are deep space probes designed to observe the Sun from widely different vantage points.  In fact, we've been a bit remiss: since '66, two more identical Pioneers have gone up: Pioneer 8 (December 13, 1967) and Pioneer 9 (November 8, 1968).  A fifth and final Pioneer was launched August 27, 1969, but its carrier rocket exploded.  The loss of that one is pretty bad; whereas the others are all spread out fairly equidistantly around the Sun, more or less as far away from it as the Earth, Pioneer "E" was going to be put in an orbit that kept it close to Earth, where it would be used to give as much as a two-week warning of dangerous flare activity.

Nevertheless, NASA is blazing along with four satellites.  Indeed, thanks to the longevity and spread-out positions of Pioneers 6 and 7, they were able to perform an unique experiment.  On Nov. 6, the two satellites were 175 million miles apart on a common line with the Sun, and scientists observed the difference in behavior of solar wind particles due to their passage through space in opposite directions.  In a similar vein, on Dec. 2, when the spacecraft reached points on a common spiral line leading out from the Sun (the star rotates, so it flings out particles in a spiral rather than linear fashion), scientists measured different kinds of solar particles coming from the same events on the Sun.

We'll have to wait for the journals to publish any papers, but this is the kind of large-scale, long-term science made possible by the Pioneer probes!


Another cool example of Pioneer science

Just four months ago, men first set foot on the Moon, fulfilling a millennia-long dream of humanity as well as culminating a decade-long Space Race between the superpowers. And the question on everyone's lips: how do you top that?

It's important to remember that the flight of Apollo 11 was not the end, but only a beginning—just as John Glenn's orbital flight, Gus Grissom's mission in Gemini 3, Wally Schirra's in Apollo 7 were all beginnings. The Moon Port is open, and it is time to start the exploration of the cosmos in earnest.

Appropriately, the flight of Apollo 12 was planned to mark an incremental expansion upon the prior mission's success. Scheduled for a November 14 launch at 11:22AM Eastern time months in advance, the second lunar mission would include the following improvements:

  • Time spent on the Moon would be 32 hours, half again more than the 21 hours spent by Apollo 11.
  • There would be two Extravehicular Activities (EVAs) rather than one.
  • The astronauts would set up a series of experiments designed to operate for one year from the lunar surface.
  • The Lunar Module (LM) would execute a pinpoint landing at Site 7 in the Sea of Storms, as opposed to the less precise touchdown made by Eagle in July
  • As a result, the astronauts would be able to recover the TV camera from Surveyor 3, which had soft-landed on the Moon two years prior.
  • The Moonwalks would be televised in color this time.
  • After lunar exploration, Apollo 12 would spend an extra day in lunar orbit photographing future landing sites.

In all, Apollo 12 promised to be only slightly more ambitious than its predecessor, but how much more ambitious than a flight to the Moon do you need?

(Un?)Lucky Seven

In 1959, NASA unveiled the identities of the first seven astronauts—the folks who would fly the Mercury capsule into space.  Over the course of two years, from 1961-1963, six of them rode a pillar of flame beyond the Earth's atmosphere, one at a time.

This month, the Soviets orbited seven cosmonauts at once.

[September 28, 1969] Apollo’s New Muses (Women Behind the Scenes in the Apollo Programme)

Seven years ago, the Journey published an article on the Women Pioneers of Space Science.  At long last, Kaye offers a much-needed update, this time focusing on the women who helped make Apollo 11's trip to the Moon possible…


by Kaye Dee

Classical literature tells us that the god Apollo was associated with the Nine Muses, the goddesses who inspired the arts, literature and science.

Our modern Apollo program also has its Muses – trailblazing women working behind the scenes in critical areas of the programme. They deserve to be better known, not just for their own impressive careers to date, but also as role models, inspiring girls and young women who might be interested in science, technology, engineering, mathematics or medicine, but are diverted away from them by the prevailing view that careers in these areas are for men, not women.

The famous ‘Dance of Apollo and the Muses’ by the Italian architect and painter, Baldassare Tommaso Peruzzi

As someone who has had to contend with these stereotypes myself, trying to establish a career in the space sector in Australia, I thought it might be interesting this month to delve into the stories of four of the women working behind the scenes in the Apollo programme: modern-day daughters of Urania, the Muse of Astronomy, Mathematics and the “exact sciences”.

The “Return to Earth” Specialist: Frances “Poppy” Northcutt

Every aspect of a lunar voyage involves moving objects – the Apollo spacecraft, the Earth and the Moon. Calculating the trajectories required for an Apollo mission to meet and go into orbit around the Moon at a particular date and time, is a mind-bending feat. But getting astronauts safely home from the Moon is even more important!

NASA’s specialist in the incredibly complex and precise calculations required to determine the optimal trajectories for the return to Earth from the Moon, minimising fuel and flight time, is Miss Frances Northcutt, who goes by the nickname “Poppy”. She is, perhaps, the only one of these ladies that you might have heard of (at least those of you in the United States), as she was such a “curiosity” during the press and television coverage of the Apollo-8 mission that she has been interviewed many times (and more on this below).

Born in 1943, Miss Northcutt earned a mathematics degree from the University of Texas, then commenced working at TRW in 1965 as a “computress”! Yes, that was her actual job title, although in Australia we’d have just called her a "computer" (a term applied here and in Britain to both men and women doing this kind of intensive calculating work). Miss Northcutt was placed at NASA’s Langley Research Centre, calculating spacecraft trajectories for the Gemini missions. She proved to be so talented in this area that within just six months TRW promoted her to engineering work with its Return to Earth task force, helping to design the computer programmes and flight trajectories to return an Apollo spacecraft from lunar orbit to Earth.

Poppy Northcutt became the first woman to work in this type of role and was soon undertaking the intricate calculations involved in enabling the Apollo astronauts to travel around the Moon and come safely home. The Moon’s lower gravity changes parameters such as fuel usage, as well as the timing of manoeuvres, so the calculations are particularly tricky. Poppy identified mistakes in NASA’s original trajectory plan, performing calculations that reduced the amount of fuel used to swing around the Moon.

When NASA decided that Apollo-8 would become a lunar orbiting mission, the task force team, including Miss Northcutt, moved to Mission Control to instruct the flight controllers on the trajectory calculations and be available to make real-time calculations and course corrections in the event of unexpected incidents during the flight. Assigned to Mission Control's Mission Planning and Analysis room, Miss Northcutt and her team have been an integral part of Apollo-8, 10 and 11 and are now preparing for Apollo-12. She is the only female engineer in the teams that work in the backrooms of Mission Control in Houston, providing support to the flight controllers.

Working Like a Man (but not being paid like one!)

“Computresses” in Miss Northcutt’s original position are classed as “hourly workers”, with their wages capped at working 54 hours per week (in other words, five nine-hour days). Their male counterparts were not only paid more (as we all know, female workers are generally paid between about half and two-thirds of the wages for a man doing the same job), they were also on salaries and paid overtime.

As an ambitious young woman, Miss Northcutt quickly realised that to earn the respect of her male colleagues and be considered a peer, she would have to work the same long hours they did – even if this meant that she was essentially working 10 or more hours a week for no pay!

Her talent and diligence paid off with her promotion to engineer, but, ironically, even though she was still being paid less than her male colleagues, Miss Northcutt tells the story that there was no normal mechanism to approve the pay rise she received with this jump from Computress! Her manager had to keep scheduling the highest possible raise as frequently as he could to bring her up to the full female rate of her new salary. 

During Apollo missions, when shifts last around 12 to 13 hours a day in Mission Control, Miss Northcutt usually commences her duty shifts for each mission around the time that the Apollo spacecraft, coasting towards the Moon, prepares to enter the lunar sphere of gravitational influence. During lunar orbit insertion she stands by to assist with new calculations, in the event of an emergency abort, and she reports for duty at Mission Control every day of the lunar phase of the mission and until the astronauts have returned safely to the Earth's sphere of influence. No one can say Poppy Northcutt isn’t pulling her weight, just like a man!

Sexism, Celebrity and Activism

As the only female engineer in Mission Control during the Apollo-8 mission, Miss Northcutt was such a “curiosity” that she received a lot of attention from journalists. While much of this coverage was not seen in Australia, from what I have heard from friends in America, I understand that many of the questions that she received were quite sexist – and even silly.

Miss Northcutt is a very pretty woman and dresses fashionably, so apparently ABC reporter Jules Bergman thought it was more important to ask about her potential to distract her male colleagues from the mission, than to ask about her crucial role: “How much attention do men in Mission Control pay to a pretty girl wearing miniskirts?” Would they have asked a male flight controller if the suit he was wearing turned the heads of the typing pool?! I gather that she gave him a polite brush off response.

A friend in the US took this photo from her television screen, giving me a glimpse of Mr. Bergman's interview with Miss Northcutt

It is bad enough when reporters focus on her appearance and ask her such inane questions, while she operates at the level of her male colleagues, for far less monetary reward. But Miss Northcutt has also reported an instance in which she discovered that the other flight engineers were covertly watching her on a video feed, from a camera trained on her while she was conducting equipment flight tests.

As a result of her personal experiences with sexism, Miss Northcutt has become a strong advocate for women’s rights, and has joined the feminist National Organisation for Women. Even in her early days at TRW, she worked to improve the company’s affirmative action and pregnancy leave policies. “As the first and only woman in Mission Control, the attention I have received has increased my awareness of how limited women’s opportunities are”, she has said. “I’m aware of the issues that are emerging. Working in this environment I can see the discrimination against women.”

TRW is happy to use Miss Northcutt's minor celebrity to promote itself, but not happy enough to pay her the same salary as her male colleagues!

However, while she is not pleased that much of the attention she has received has been focussed on her appearance, or treating her as a rare exception to the male-dominated world of spaceflight, Miss Northcutt has said that she recognises that being a woman visibly occupying a critical position in the space programme does send a very positive message to women and girls: a career in science and technology is possible if you want it – and are prepared to work for it!

Miss Northcutt has received letters and fan mail from around the world (including several marriage proposals, it seems!) She has said that she is motivated to continue to advocate for women’s rights in the workplace by the letters she has received from young women, who have said how much she has inspired them. 

Whoever Heard of a “Software Engineer”? Margaret Hamilton

The Apollo missions not only need precise trajectories for their lunar voyages – they also need software for their onboard flight computers, which control so many aspects of the flight. If you’re not familiar with this term, “software” describes the mathematical programmes that tell a computer how to carry out its tasks, and a “software engineer” applies the engineering design process to develop software for those different tasks.

The Director of Apollo Flight Computer Programming is Mrs. Margaret Hamilton Lickly, who prefers to be known professionally as Margaret Hamilton.I've heard that women in the United States who prefer not to be categorised by their marital status, are now starting to use the designation "Ms.". I don't know if Margaret Hamilton is using this new honorific, but it seems to me appropriate to apply it to her in this article. 

33-year-old Ms. Hamilton is another woman playing a crucial role in NASA’s lunar program. Not only is she a pioneer in software engineering, she even coined the term!


Like Miss Northcutt, Ms. Hamilton is also a mathematician, having studied at the University of Michigan and Earlham College. Shortly after graduating in 1958, she married her first husband, James Hamilton, and taught high school mathematics and French, before taking a job in the Meteorology Department at the prestigious Massachusetts Institute of technology (MIT) in 1959, a few months before the birth of her daughter.

Ms. Hamilton developed software for predicting weather, and in 1961 she moved to MIT’s Lincoln Lab for the Semi-Automatic Ground Environment (SAGE) Project, adapting weather prediction software into a programme used by the U.S. Air Force to search for potential enemy aircraft. At the Lab, she was the first person to get a particularly difficult programme, which no-one had been able to get to run, to actually work! While working on SAGE, Ms. Hamilton began to take an interest in software reliability, which would pay dividends during Apollo-11’s lunar landing.

A Calculated Move

When Margaret Hamilton learned about the Apollo project in 1965, she wanted to become involved in the lunar programme, and moved to the MIT Instrumentation Laboratory, which was developing the Apollo Guidance Computer. She was the first programmer hired for the Apollo work project at MIT and has led the team responsible for creating the on-board flight software for both the Apollo Command and Lunar Modules. She also serves as Director of the Software Engineering Division at the Instrumentation Laboratory.

The Apollo Guidance Computer was installed on both the Command and Service Modules. Astronauts communicated with it using a numeric display and keyboard

While working on the Apollo software, Ms. Hamilton felt that it was necessary to give software development the same legitimacy as other engineering disciplines. In 1966, she therefore coined the term “software engineering” to distinguish software development from other areas of engineering. She believes that this encourages respect for the new field, as well as respect for its practitioners.

On one occasion when her young daughter was visiting the lab, the little girl pushed a simulator button that made the system crash. Ms. Hamilton realised immediately that the mistake was one that an astronaut could make. While Ms. Hamilton has said that she works in a relationship of "mutual respect" with her colleagues, when she recommended adjusting the software to address the issue, she was told: “Astronauts are trained never to make a mistake.” Yet during Apollo-8, astronaut Jim Lovell made the exact same error that her young daughter had!

While Ms. Hamilton’s team was able to rapidly correct the problem, for future Apollo missions protection was built into the software to prevent a recurrence. With her interest in software reliability, Margaret Hamilton insisted that the Apollo system should be error-proof. To achieve this goal, she developed a programme referred to as Priority Displays, that recognises error messages and forces the computer to prioritise the most important tasks, also alerting the astronauts to the situation.

In Part 2 of my series of Apollo-11 articles, we saw how, during the descent to the Moon’s surface, the Lunar Module’s computer began flashing error messages, which could have resulted in Mission Control aborting the landing. However, the Priority Displays programme gave Guidance Officer Bales and his support team confidence that the computer would perform as it should despite the data input overloads that it was experiencing, and that the landing could proceed.

Ms. Hamilton and her 100-strong team continue to work on developing and refining the Apollo flight software, and I’m sure that they will contribute to whatever future spaceflight projects NASA develops, stemming from Vice-president Agnew’s recently-delivered Space Task Group report to President Nixon.

“I’ve Got Rocket Fuel in my Blood”: JoAnn Morgan

Mission safety and reliability are, of course, critical, but Apollo-11 could not even have made the historic lunar landing if the mission had been unable to launch in the first place! When Apollo-11 lifted off, there was one lone woman in the launch firing team at Kennedy Space Centre’s (KSC) Launch Control Centre, who helped to ensure that would happen – Instrumentation Controller JoAnn Morgan.

Mrs. Morgan, who was born in December 1940, has described herself as a “precocious little kid” who loved mathematics, science and music, and wanted to become a piano teacher. However, after her family moved to Florida from Alabama, she was inspired by the launch of the first American satellite, Explorer-1, in January 1958, and its significant discovery of the Van Allen Radiation Belts. It was the “opportunity for new knowledge” that space exploration represented that filled the teenager with a desire to be part of the new space programme.

Soon after, JoAnn saw an advertisement for two (US) Summer student internship positions, as Engineer’s Aides with the Army Ballistic Missile Agency at Cape Canaveral. As we know, job openings are often advertised separately for males and females, but this ad only referred to “students” (not “boys”), so she took the chance, decided to apply, and was successful thanks to her strong marks in science and mathematics.

So, at just 17, JoAnn Hardin, as she was then, began working as a University of Florida trainee for the Army at Cape Canaveral Air Force Station. “I graduated from high school on the weekend and went to work for the Army on Monday. I worked on my first launch on Friday night” is how Mrs. Morgan describes the beginning of her NASA career. The Army programme she was working with became part of NASA when it was established in October 1958.

Supportive Male Mentors

While undertaking her degree in mathematics at Jacksonville State University, Mrs. Morgan continued her Summer internships with the NASA team launching rockets at Cape Canaveral. The young student’s potential did not go unnoticed, and she acknowledges that she received significant support in furthering her career from several senior NASA personnel, including Dr. Wernher von Braun, the chief architect of the Saturn V rocket, Dr. Kurt Debus, the first director of Kennedy Space Centre and Mr. Rocco Petrone, Director of Launch Operations at KSC.

Mentors Kurt Debus, left, and Rocco Petrone, right, during the Apollo 7 flight readiness test in the blockhouse at Complex 34

Dr. Debus provided Mrs. Morgan with a pathway to becoming an engineer, and she gained certification as a Measurement and Instrumentation Engineer and a Data Systems Engineer, which enabled her to be employed as a Junior Engineer on the launch team. “It was just meant to be for me to be in the launching business,” she says. “I’ve got rocket fuel in my blood.”

As a young woman joining an all-male group, Mrs. Morgan was fortunate that (unbeknownst to her at the time) her immediate supervisor, Mr. Jim White, insisted that the men on the launch team address her professionally, not be “familiar”, and reportedly told them that “You don’t ask an engineer to make the coffee”! (Which, of course, is often a task that falls to the women in any office).

Professional Disrespect

Despite Mr. White’s efforts to create an environment of respect for his first female engineer, Mrs. Morgan has still described experiencing sexism and harassment, treatment similar to the experiences of Miss Northcutt. With no female restrooms in the launch blockhouses at Cape Canaveral, when she needs to use the restroom, she has to ask a security guard to clear out the men’s room so that she can enter. She has reported receiving obscene phone calls at her station (which disappointingly could only have come from colleagues).

However, like Miss Northcutt, while she has said that she sometimes feels a sense of loneliness as the only woman in the team, Mrs. Morgan “wants to do the best job she can” and works the same long hours as her male colleagues. In 1967, as the Apollo programme was ramping up, her dedication to her work had tragic consequences. The stress and long hours of her job contributed to her miscarrying and losing her first child.

The crowded interior of the blockhouse at Launch Complex 34, where Mrs. Morgan has often worked

Perhaps the most shocking example of professional disrespect and harassment (which could be considered an assault) that Mrs. Morgan has experienced was during a test being conducted at the blockhouse for Pad 34, where the first Apollo missions were set to be launched. When preparing to acquire some test results, she was actually struck on the back by a test supervisor, who aggressively told her that “We don’t have women in here!” She had to appeal to her own supervisor, Mr. Karl Sendler (who developed the launch processing systems for the Apollo programme) to confirm that she could remain. He told her to disregard the test supervisor and continue with her work (though it’s not clear if any action was taken against the offending supervisor).

On Console for Apollo-11

The unpleasant incident with the test supervisor prompted many of Mrs. Morgan’s colleagues and senior managers to come forward in expressing acceptance and respect for her as part of the team. Nevertheless, even though she has worked launches for Mercury, Gemini and Apollo, received an achievement award for her work during the activation of Apollo Launch Complex 39, and been promoted to a senior engineer, Mrs. Morgan has frequently found herself rostered for the inconvenient evening shifts. Since her husband is a school teacher and band-leader, this hasn’t always allowed them a lot of time to be together.

Until Apollo-11, Mrs. Morgan was also not selected to be part of the firing room personnel for a launch, usually being stationed at a telemetry facility, a display room or a tracking site for launch. She found this very disappointing, as she always wanted to feel the vibrations from a launch that her colleagues described.

But her desire to experience the incredible shockwave vibrations of a Saturn-V lift-off was finally achieved with the launch of Apollo-11. Recognising that Mrs. Morgan is his best communicator, Mr. Sendler quietly obtained permission from Dr. Debus for her to be the Instrumentation Controller on the console in the firing room for Apollo 11! (This achievement also had the bonus of working day shifts, so that she has been able to spend more time with her husband).

Can you spot the lone woman in a sea of men? In this picture of the Launch Control firing room during Apollo-11, Mrs. Morgan is in the third row, just to the left of centre.

A successful launch is critical to each mission and Mrs. Morgan believes that her prime role in the launch of the historic mission will help to further her career within NASA. Although she has not received the same level of press and television attention as Miss Northcutt, she does hope that even the photos of her in Launch Control – a lone woman in a sea of men – will help to inspire young women to aspire to careers in the space programme, so that, at some time in the future, photos like the ones she is in now “won’t exist anymore.”

Making Packed Lunches for Astronauts: Rita Rapp

You could say that the astronauts are the most fragile component of each Apollo mission. Nutrition is important in keeping crews healthy and functioning during a flight, so space food has to be as appetising as possible, within the constraints of spaceflight and the weightless environment – especially as missions to the Moon, and future space stations and lunar bases will keep astronauts in space for longer and longer periods. 

Physiologist Miss Rita Rapp, head of the Apollo Food Systems team, has been looking after the astronauts' bodies – and stomachs – since she joined NASA in 1960. For the Apollo programme, she has developed the space food and food stowage system designed to keep the astronauts supplied with the right mix of calories, vitamins, and nutrients to enable them to function well in space. One of her goals has been to ensure that crews have something worth eating during their spaceflights.

Born in 1928, Miss Rapp studied science at the University of Dayton and then took a Master’s in anatomy at the St. Louis University Graduate School of Medicine. She was one of the first women to enrol in this school. Graduating in 1953, she took a position in the Aeromedical laboratories at Wright-Patterson Air Force Base, where she began assessing the effects of high g-forces on the human body, especially the blood and renal systems, using centrifuge systems.

In 1960 Miss Rapp joined NASA’s Space Task Group preparing for the Mercury manned spaceflight programme, later transferring to the Manned Spacecraft Centre in Houston. For the Mercury program, she continued her work on centrifugal effects on the human body. She also designed the first elastic exercisers for Mercury and Gemini missions, devised biological experiments for the astronauts to conduct in-flight, and developed the Gemini medical kit.

From Aeromedicine to Space Food

In 1966, as the Apollo programme was ramping up, Miss Rapp joined the Apollo Food Systems team. Although she has continued to work on space health and hygiene projects, in her new role her primary focus became looking at systems for storing food onboard the Apollo spacecraft. Working with dieticians, and commercial companies, she has investigated the ways space food could be packaged and prepared, and become the main interface between NASA’s Food Lab and the astronauts.

Although she tries to use as much commercially available food as possible, Miss Rapp and her team are also continually experimenting with new recipes in the food lab, gradually replacing the earlier “tubes and cubes” style of space food used in Mercury and Gemini with meals that are closer to an everyday eating experience.

She has developed improved means of food preservation, such as dehydration, thermostabilisation, irradiation and moisture control, which allows for a wider range of foods to be suitable for spaceflight, and I have no doubt these useful technologies will find their way into commercial food preparation and onto our supermarket shelves in the not-too-distant future. 


Working with the Whirlpool Corporation, Miss Rapp has developed new forms of food packaging for Apollo, such as the spoon bowls, “wet packs” and cans for thermostabilised food. These containers enable astronauts to eat with more conventional utensils, instead of sucking food out of a tube or plastic bag. Creating a more natural, homelike eating experience is good for the astronauts’ morale and psychological health during missions. You can discover more about Miss Rapp's space food developments in my articles on the various Apollo missions. 

Miss Rapp takes great pride in providing the Apollo crews with the flavours and comforts of home. “I like to feed them what they like, because I want them healthy and happy,” she says. She takes note of their individual food preferences, often devises new recipes and prepares the individual meals of each Apollo astronaut separately. Her home-made sugar cookies, that she bakes herself, are a special favourite of Apollo crews, and additional supplies are included as snacks in the onboard food pantries of the Command and Lunar Modules. She also likes to provide the crews with special food “surprises”, such as the turkey dinner enjoyed by the Apollo-8 crew in lunar orbit on Christmas Eve last year.


Just the Beginning

The women of Apollo who I’ve discussed in this article are trailblazers for women’s participation in mathematics, engineering, and other technical aspects of spaceflight.  While they are not the only women in professional roles in the space sector, female participation in space careers, and in science, engineering, and technology more generally, is still very low.

I hope that by highlighting the exciting Apollo-related careers of the four women above, it will plant a seed in the minds of young girls reading the Journey that they, too, can aspire to careers in scientific and technological fields that are generally thought of only as careers for men. I also hope that growing levels of female participation in the workforce, together with feminist activism, will eventually consign the sexism, discrimination and harassment that women working in all careers experience at present, to the history books—though I won’t hold my breath on it happening any time soon.
