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


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!

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

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.




[Feb. 18, 1961] Lost and Found (Explorer 9 and Discoverer 20)

February is definitely making up for January's relative paucity of space flights; this week, in particular, has been noteworthy. 

I'd held off reporting on NASA's February 16 launch of Explorer 9 since, well, NASA lost it.  You see, the satellite's beacon was tracked through half an orbit, but then the signal was lost, and no one could confirm that the thing was still up there.  Yesterday, the vehicle was tracked optically, and it looks as if the probe will be able to fulfill its mission.

'What mission?' you ask.  Explorer 9 is a big, polka-dot balloon.  Unlike Echo, whose main purpose is to bounce communications signals across continents, Explorer 9 is an incredibly simple experiment.  By tracking the path of the balloon, scientists can tell a great deal about the air density of the upper atmosphere and the effect of the sun and solar wind thereon.  They will also be able to refine their gravity maps of the world by tracing the satellite's dips and rises as it travels.  It is the very simplicity of this satellite that allows it to function even without a functioning beacon.  As for the polka-dots, they are designed to help regulate the temperature of the 11-foot wide aluminum/mylar sphere.

Perhaps more exciting than the satellite itself is the rocket that launched it.  It was a cheap, civilian-made, four-stage, solid-fuel rocket called Scout.  The exciting bit is that it's the first purpose-built booster that isn't a knock-off of a missile (technically, that honor might go to Vanguard, but it traces its origins to the Viking sounding rocket, itself an evolution of the V2).  It's cheaper than the military missiles, too.  This launch is actually the second try of the Scout and balloon sat, the first ending in failure during ascent back in December.  The mission also marks the christening of a new orbital launch facility at Wallops Island, Virginia.  That base has been a sounding rocket pad for a long time, but now it joins Cape Canaveral and Vandenberg Air Force Base as an origin for true spaceflight missions.

In other news, the Air Force launched its twentieth Discoverer yesterday atop a Thor Agena rocket of decidedly military origin.  Once again, the capsule-return probe went into polar orbit, the kind that is best for espying global weather conditions…or enemy army bases.  The flyboys plan to wait an unprecedented four days to recover the capsule, which reportedly contains emulsions for detecting radiation, and probably also for catching a glimpse of Khruschev's new Model A.  More on that as it crosses my desk.

In the meantime, I'm finishing up this month's IF, and picked up a recent reprint of A.E.Van Vogt's The War against the Rull.  We'll see if I get those reviews done before the next space spectacular.
