[February 16, 1969] Triumph, Tough Luck and Turmoil (European Space Update)



by Kaye Dee

The accelerating pace of the US and Soviet space programmes over the past few months has drawn our attention away from space developments in other parts of the world, especially with the excitement of the historic Apollo 8 lunar mission so recently behind us and Apollo 9’s in-orbit test flight (finally!) of the Lunar Module next month. But there have been many developments on the European space scene since I wrote about it in May last year, so I think it’s time for an update!

Triumph: ESRO 1A Finally in Orbit
My previous European space report noted that the European Space Research Organisation’s (ESRO) first satellite, ESRO 2B, reached orbit ahead of ESRO 1A, the latter satellite delayed due to difficulties in the development of its instrumentation payload. But ESRO 1A was finally launched on 3 October 1968 from Vandenberg Air Force Base in California, using a Scout launch vehicle.

Fired into a 90° polar orbit, with an initial apogee of 930 miles and a perigee of 171 miles, ESRO 1A is designed for a nominal lifetime of six months. However, it is already looking likely that the satellite will survive much longer and possibly still be in orbit when its follow-up twin ESRO 1B is launched later this year (presently planned for some time in October).

The ESRO1 missions were first outlined in 1963 at scientific meetings of COPERS (Commission Préparatoire Européenne de Recherche Spatiale, which is the French name for the European Preparatory Commission for Space Research, a predecessor of ESRO), but the programme has been developed as a joint venture between NASA and ESRO. NASA provided the Scout vehicle for ESRO 1A, although ESRO will purchase the Scout launcher for the ESRO 1B flight.

Designed by ESRO, the construction of both ESRO 1 satellites is all-European: Laboratoire Central de Telecommunications (Paris) is the prime contractor, with assistance from Contraves AG (Zurich), and Antwerp-based Bell Telephone Manufacturing Company, with final testing taking place at ESRO’s ESTEC facility. Weighing about 187 pounds, the cylindrical, non-stabilised ESRO 1 satellites are 30 inches in diameter and 36.6 inches tall (specifically designed to fit within the Scout vehicle fairing) and powered by solar-cells.

ESRO 1A (‘Aurora’) and ESRO 1B (‘Boreas’) have been designed to study how the auroral zones respond to geomagnetic and solar activity. Their payloads are directly derived from earlier sounding rocket experiments measuring the radiation characteristics of the upper atmosphere. In orbit, the satellites’ axis of symmetry is magnetically aligned along the Earth's magnetic field. They can make direct measurements as high-energy charged particles from the Sun and deep space plunge from the outer magnetosphere into the atmosphere (ESRO 1B will be placed in a lower orbit that 1A to provide comparative data at different altitudes). The satellites can also investigate the fine structure of the aurora borealis and correlate studies on auroral particles, auroral luminosity, ionospheric composition, and heating effects.

ESRO 1A carries seven scientific experiments chosen to measure a comprehensive range of auroral effects. Identical or similar experiments will be carried on ESRO 1B.

Tough Luck: Another ELDO Launch Failure…
Unfortunately, the European Launcher Development Organisation (ELDO) has yet to taste the same success as ESRO, with repeated failures in its Europa satellite launcher test flights, which I've covered in detail in previous articles.

Despite the loss of both Europa F6/1 and F6/2 due to failures of the French ‘Coralie’ second stage, the Europa F7 flight was scheduled for a November launch last year, as the first vehicle to fly with all three of the rocket’s stages active. This eighth firing in the ELDO test programme marked the beginning of Phase 3 of the Europa test flights. It would be the first attempt to launch ELDO’s Italian-built STV (Satellite Test Vehicle) satellite into orbit, as well as the first time that the ELDO down-range guidance and tracking station at Gove in the remote Arnhem Land region of the Northern Territory (primarily developed by Belgium) would actively participate in a Europa launch.

The failure of the Coralie stage to separate during the F6/2 launch, due to an electrical fault, meant that modifications had to be made to prevent a recurrence of the issue. So there was plenty of tension (and frustration) in the air when last-second delays halted two attempts to launch F7 on 25 November. Both aborts occurred just 35 seconds before the rocket was due to lift off, and were caused by the discovery of a fault in the Coralie staging system between the first and second stages – nobody wanted a repeat of F6/2!

A launch attempt on 27 November was cancelled due to another fault, as was a fourth attempt on the 28th, which was caused by a faulty indication in a pressure switch system in the engines of the British Blue Streak first stage.

Finally, on the fifth attempt, Europa F7 lifted off on 30 November (Australian time; still 29 November in Europe), but this flight, too, was doomed to be short-lived. The second stage separated and functioned perfectly: this time it was the West German ‘Astris’ third stage that caused the failure.

The Astris stage separated and ignited as expected but burned for just seven seconds (instead of the planned 300 seconds) before it exploded. Investigations as to the cause of the failure are ongoing, but at present there are three possible causes under consideration: rigid pressurisation pipes that may have fractured; an explosive bolt, part of the WREBUS flight safety destruct system, that may have been inadvertently been triggered by a stray electrical current; or a rupture of the tank diaphragm in the third stage, which separates the fuel and oxidiser. The diaphragm may have been weakened during pre-flight preparations. At present we can only await the outcome of the investigations and hope that they do not delay the launch of Europa F8, currently scheduled for June or July this year.

…And a Satellite Lost
While it was not the main objective of the F7 flight, it is particularly disappointing that the Italian test satellite did not reach orbit, as it would have become the second satellite launched from Woomera, exactly one year after Australia’s own WRESAT.

The octagonal prism-shaped STV satellites (successors will be flown on Europa F8 and F9) have been built for ELDO by Fiat Aviazione. The 472 pound satellite carries instruments to characterise the launch environment of the Europa vehicle, providing information on the conditions and stresses that future satellites launched on Europa vehicles will need to be capable of surviving.

Despite the loss of both the rocket and the satellite, ELDO has been referring to Europa F7 as a “successful trial”, as it has enabled its engineers to acquire data about the performance of the Coralie second stage in flight and came close to placing a satellite into orbit. ELDO representatives are saying that, the Europa vehicle has “emerged for the first time as a practical proposition.”

Turmoil: the State of European Space Policy
Last May, I asked whether Britain had lost its way in space, and whether European space plans would flourish or wither, due to changing views on the future direction of Europe’s space activities and reductions in funding. Since then, the outlook has become even more uncertain, with disagreements over juste retour project work allocations and the ELDO budget creating turmoil.

In November last year, Ministers, space organisation representatives and space experts from 16 European countries, as well as Australia and Canada, met for the third European Space Conference, held in Bonn, West Germany. At this meeting, a proposal was put forward to merge ELDO and ESRO to form a pan-European space authority by early 1970, which would be known as the European Space Agency.

This idea proved popular with many of the attending nations, but less so with Britain, which expressed the view that it was unlikely that Europe could launch satellites economically. As noted last year, Britain has already announced its intention to withdraw from ELDO, although it has committed to continue supplying Blue Streak first stages for the Europa II vehicle.

However, the British Government has offered to back a revised European space programme designed to yield “practical results”. Britain wants Europe to concentrate on developing applications satellites for weather forecasting, telecommunications, and scientific research, giving up the development of independent European launchers in favour of using American vehicles.

The British proposal includes an offer to contribute to a project for an “information transfer satellite” to be completed by 1975, providing a point-to-point television relay service between London and Paris for the European Broadcasting Union. In addition, Britain would participate in a long-term applied research programme to improve European industrial space capability, in conjunction with funding an immediate economic study of the market for applications satellites. The quid-pro-quo for British support for this ambitious “practical space programme” is that the UK must be released from its present financial commitment to ELDO. This is certainly ironic, given that Britain was the driving force behind the original creation of ELDO!

ELDO's Budget Crisis
After the failure of Europa F7, the ELDO Council met on 19-20 December to vote on the organisation’s 1969 budget, with Britain again the fly in the ointment, declaring that it would not support the new “austerity plan” compromise budget proposed by West Germany to cover the final two years of the Europa-1 development programme.

Using a loophole in the ELDO Convention to characterise the German proposal as a “further programme” (ie: it was not part of the original ELDO programme that it had signed up to), Britain declared that it had “no interest” in the plan and so was not obliged to contribute to it financially. It would only support the 1969 budget if its outstanding contribution to ELDO was reduced to £10 million for the years 1969, 1970 and 1971.

Italy took a similar line, supporting the British view and declaring itself “not interested”, and would not vote for the 1969 budget. In addition, Italy formally rejected as inadequate an offer to become the prime contractor of the apogee motor in the Symphonie communications satellite programme.

This recalcitrance on the part of Britain and Italy has plunged ELDO into a budget crisis, and the organisation has been operating on a contingency funding basis since 31 December. Practical considerations, and the terms of the ELDO Convention, indicate that the impasse needs to be resolved within three months, at which point a budget must be approved or the original treaty becomes invalid.

An excerpt from the journal Nature, reporting on ELDO's budget crisis

A meeting of the relevant Ministers from all seven ELDO member states is currently scheduled for 26 February to seek a political solution to the problem and find a way forward for Europe’s space ambitions before they fragment. What’s that Chinese proverb? “May you live in interesting times”!

An Australian Postscript: No WRESAT-2
In my article on the launch of Australia’s first satellite at the end of November 1967, I mentioned that the Weapons Research Establishment was planning to put a proposal to the Australian Government for the establishment of an Australian space programme, managed by the WRE. This proposal went to the Cabinet for consideration last year, but was rejected by the Government on the basis of cost, despite the modest budget it was proposing. This is not the first proposal for an Australian space programme that has been rejected by Cabinet, which seems to have little appetite for funding Australian civil space projects. To the frustration of all those involved, it looks like WRESAT-1 will not, after all, be followed by WRESAT-2.

Signing off
Well, in the vernacular of your beloved Walter Cronkite, "That's the way it is." I'm sorry I haven't happier news to report just yet, but you'll hear it here first when I have it!

(And my thanks to my Uncle Ernie, the philatelic collector, for providing the selection of space covers (envelopes) that I have used to illustrate this article.)


[November 30, 1967] One door closes… (December 1967 Analog and Australia joins the Space Race!)


by Gideon Marcus

Mags or paperbacks?

The latest issue of Yandro has got a nice piece from Ted White reviewing the latest (and best?) tome on science fiction by Alexei Panshin.  The best part of White's article is his gentle but lengthy disagreement over the status of magazines versus paperbacks.  Both White and Panshin agree that the paperback novel format is The Next Big Thing (indeed, it's already here), but they disagreed on their role and prospects.

Panshin sees the science fiction digests as a continuation of the pulps, with all the negative connotations attached thereto.  He thinks they will eventually die.  White strongly disagrees.  Firstly, he notes that pulp does not equal bad–many extremely talented authors got their start cranking out a half million words for the old mags.  Indeed, White says magazines are now populated by a stable of established writers who have perfected their trade while the paperbacks, since they are a buyer's market, will publish anything.  Essentially, the books have taken the role the magazines had in the glut days of the early '50s.

White goes on to say that paperbacks are great, but 1) mags are the main outlet for short stories, and some authors are just better at the short form, and 2) editors keep mags going for the love of it.  This means they are likely to survive longer than purely economic considerations would suggest.

It's a good piece.  I'd give it a read.

The issue at hand

Speaking of which, should you give the strikingly covered latest issue of Analog a read?  Well, if you're one of the 30,000 subscribers who gets it delivered, sure go ahead.  If you're eyeing it at a newsstand, you'll want to read further…

Dragonrider (Part 1 of 2), by Anne McCaffrey

In Weyr Search, the first installment of this serial-in-all-but-name, we were introduced to planet Pern.  It is a fraught former Earth colony, severed from its homeworld for thousands of years and ravaged periodically by rhizomic attacks from a nearby world.  The only defense against the "threads" are fire breathing dragons ridden by telepathically connected humans.

The problem is it's been four centuries since the last attack and the "weyrs" of dragronriders have been allowed to go fallow.  Only Benden Weyr is left, and it is woefully undermanned and underdragoned.

This latest installment in the saga of Pern opens up sometime after the last.  Lessa, heir to the Hold of Ruatha and now Weyrlady by virtue of her communion with the dragon queen Ramoth, has shacked up with the F'lar, head of the dragonriders.  Not because the two like each other, but because that's the law: Weyrladies and Weyrleaders must get hitched.

The thread has begun to fall, and the dragons are sorely taxed to meet the challenge, teleporting in and out of the frigid between to intercept the alien spores.

(Note: What do you call it when a dragon relieves itself between?  An ICBM!)

Despite the perseverence of F'lar's crew, the thread has the upper hand–until Lessa accidentally discovers that dragons not only can teleport and telepath, but they can also time travel, too!  (telechron?) As one might expect, this changes the whole equation…but maybe not for the better.


by John Schoenherr

I dunno.  I was expecting a rousing Battle of Britain story, with never so much being owed by so many to so few.  The thread would start gradually, the brave fighters would fight to their limits, and through ingenuity and tenacity, eventually win.  The story would get extra points for being by and from the viewpoint of woman, a rare thing in science fiction, particularly in the mag that Campbell built.

Instead, the story is badly paced, lurching from scene to scene.  There is no build-up to the thread strike, no mounting of tension; it is just suddenly upon them.  McCaffrey throws psionic conceits against the wall to see which ones stick (Lessa not only discovers time travel, but she is the only one who can communicate with all of the dragons–unlike the other riders, who can only communicate with their bonded dragon).

Beyond that, the two main characters are thoroughly unlikeable, by turns yelling and sardonically sniping at each other.  An element of violence suffuses their interactions, with F'lar and Lessa's couplings being referred to as not less than rape.  It all feels very Marion Zimmer Bradley.  I've said before that Lessa feels like a wish-fulfillment character for the author.  This hypothesis is only becoming more concerning.

What's frustrating is I feel there could be an interesting story here in the hands of someone else.  Jack Vance has already written a thematically similar tale with his The Dragon Masters.  It's clear that Campbell wants Pern to be the next Dune, complete with striking Schoenherr covers.  Thus far, I'd say McCaffrey isn't up to the task.

I was originally going to give the installment a bare three stars, but I think I've talked myself out of it.

Two stars.

The Destiny of Milton Gomrath, by Alexei Panshin

In this short short, an orphaned garbage collector spends his life convinced that his existence of drudgery is a mistake, and that someone, somehow, will rectify the mistake some day.

Turns out he's right, but that may not be a good thing.

This could be the start of a mildly entertaining Laumer novel.  Instead, it ends right after the first punchline.

Blink and you'll miss it: three stars.

Whosawhatsa?, by Jack Wodhams


by Kelly Freas

Picture a world where a sex change is as complete and easy as an appendectomy…and reversible, to boot!  Now picture the most complicated legal case possible involving a married couple seeking a divorce, both parties of which have swapped genders.  And there are children involved, multiple paramours, probate issues, and a Strong Public Interest.

On the one hand, this story is a drag.  The attempts to make it "funny", mostly consisting of endless scenes in which the judge assigned the case contemplates suicide rather than attempt presiding, are a flop.  Also, one gets the feeling that if women's lib had advanced in the story as much as medical science, most of the legal issues and many of the social ones would be irrelevant.  Particularly if 1) we could extend the legal rights currently afforded women in the federal government to all women, and 2) we could approach homosexuality with a less than medieval attitude.

That said…

There is very interesting exploration of what it means to change genders and the motivations that underly the desire to make such a transition.  While the situation is made as ludicrous as possible, the subjects, for the most part, are taken seriously.  I actually found the piece remarkably progressive, especially for Analog.  Certainly, I've never read anything like it before.

Three stars.

Beak by Beak, by Piers Anthony


by Kelly Freas

An alien spacecraft orbits the Earth, neither communicating nor responding to communications.  Meanwhile, a red parrakeet arrives at the home of a bird-keeper and joins his avian pet family for a time.

This is a pleasant pastoral piece that tries a little too hard to get its message across.  Still, I'll read something like this a thousand times before I'll read Chthon again.

Three stars.

Venus and Mercury—Locked Planets? by R. S. Richardson

Dr. Richardson writes so-so science fiction, but I generally quite like his science fact articles.  This one talks about the newly discovered rotation rates of Venus and Mercury, as well as what they might mean in relation to the history of the solar system.

On the one hand, I learned a bit, and that's significant given that I know a lot of astronomy.  On the other, I felt the pictures were worth a thousand words, and I found myself skimming a lot of the text.  In other words, maybe 20 pages wasn't necessary to make the point (God help us–next month's science article will be 10,000 words!).

Still, four stars.

A Question of Attitude, by Christopher Anvil


by Kelly Freas

A recruit for the interstellar patrol finds himself in an increasingly difficult series of imaginary tests, ones that stick him in mortal peril in a simulated alien planet environment.  He seems to fail each one, ending up "dead", yet the Lt. Colonel in charge of training seems to think he has promise.

Normally, Anvil and Campbell are a toxic combination.  This time around, the story is kind of interesting.  I also rather enjoyed the nihilistic suggestion that the recruit's success is measured in the degree of his failure, and also that passing the tests only means his life is about to get worse.  It fits with the whole zeitgeist of our current engagement in Vietnam.  Even if Joseph Heller did it better.

Three stars.

Psi Assassin, by Mack Reynolds


by Kelly Freas

Lastly, yet another of Reynolds' tales of Section G, the interstellar agency whose job is to make sure no human planet ends up too backwards, lest the race become prey to an ominous but yet unmet alien menace.  This time, a psionic assassin is sent to kill the head of a Latin dictatorship.  The problem: agent Ronny Bronston has already dispatched said leader and taken his identity!

We have all the hallmarks of a Reynolds Section G story: endless historical lectures (that never seem to have any object lessons beyond the mid-20th Century), flippant personalities that leach the story of any gravitas, the lone female agent (Reynolds never lets us forget her sex), and a happy ending.

Reynolds has done decent work with this series, but less often than not.

Two stars.

Doing the math

So who's right?  Alex or Ted?  Based on this month, I'd give the nod to Ted.  While Analog was on the mediocre side, managing just 2.8 stars, other magazines fared much better.  Both Galaxy and New Worlds scored 3.2 stars.  Fantasy and Science Fiction was also pretty good (3.1).  If was a bit tired, but par for the course (2.8), and while Amazing's 2.7 score puts it at the bottom of the pack, it actually is on an upward trend.

You could fill two magazines with all the superior stuff that came out this month, which is a good crop.  Sadly, McCaffrey wrote the only woman-penned piece, and it wasn't very good (though it was better than Poul Anderson's novella in Galaxy).

I give magazines at least a few more years…


But that's not all we have for today.  All the way from Australia comes this exciting stop press in the world of space news!:

“Australia Joins the Space Club!”

Although Australia has supported American and British/European space efforts over the past decade, just yesterday, on 29 November we finally gained our own membership of the Space Club by placing our first satellite, WRESAT-1, into orbit. I’ve written articles previously about the first satellites of France and Italy, so it gives me great pride to report on Australia’s own satellite launch.


WRESAT-1 under construction in at the WRE

WRESAT-1 (WRE Satellite) has been a joint project of the Weapons Research Establishment (WRE) and the University of Adelaide, with significant support from the United States. In 1966, the Advanced Research Projects Agency (ARPA) offered Australia a spare Redstone rocket from the ARPA-led Project Sparta programme at Woomera as a satellite launcher. Sparta has been the final phase of a US/UK/Australian re-entry physics research programme commenced in 1960, investigating radar-echo phenomena created by re-entering missile warheads. The Sparta team even offered to prepare and fire the Redstone for the WRE.

“A Rush Job!”

The scientists and engineers involved in the Australian upper atmosphere research programme took advantage of the proposal to move their instruments from sounding rockets to satellite. However, the Sparta launch offer placed the satellite project on a very tight schedule, as the spacecraft would have to be ready for launch by the end of 1967, when the Sparta project would be complete and the Americans returning home. So, in just 11 months Australia’s, WRESAT has been designed, constructed, tested and was finally launched on 29 November. Its development has been an example of local “make-do” ingenuity, as much of the testing equipment needed was not available in the country.

Australia’s first satellite has been designated WRESAT-1 because my WRE colleagues hope that it will have many successors. Australia doesn’t yet have a space agency like NASA, but the WRE is putting a proposal to the Australian Government for a national space programme, and we hope that it will be funded, with the WRE formally designated as the Australian national space agency.

Given the short development period, WRESAT’s scientific payload consists of instruments similar to those already flown in the Australian sounding rocket programme conducted in conjunction with the University of Adelaide Physics Department. The university team has developed a suite of instruments to study solar and ultra-violet radiation, atmospheric ozone and molecular oxygen density, as well as measuring the temperature of the solar atmosphere.

“Going Up From Down Under”

After an aborted launch attempt on the 28th, the Redstone lifted-off flawlessly on the 29th to place WRESAT into a polar orbit, where it is being tracked, and its telemetry signals recorded, by NASA’s Satellite Tracking and Data Acquisition Network – a service also generously provided free to Australia.


WRESAT soars on its way to orbit from Launch Area 8 at Woomera

Because of its short development time, a solar array could not be designed for WRESAT, and the satellite is only battery-powered. This means it will have a very short operational lifespan, but we expect it to gather a large amount of data on the upper atmosphere that will provide a check on the data already gathered by sounding rockets.

Let’s hope that WRESAT-1 marks the start of Australia’s true Space Age, and that this country will soon “shine as brightly as the Southern Cross”, as President Johnson has put it in his congratulatory telegram on our first national launch!
