Red Moon? (The launch of Mechta; 1-03-59)

Bet on the Russians to throw us a curve.

Last month, I crowed that America had won the Space Race in 1958 with the launching of Score, the first communications satellite, and of the mildly successful Pioneer series.  Well, the Soviets apparently just wanted to give us a false feeling of security, because they have finally launched their own moon probe.  They call it "Mechta" or "Dream," while the press has affectionately (or derisively, as they drink their sour grape punch) dubbed it "Lunik."

It takes a day-and-a-half to get to the moon, so the Reds may yet suffer a Pioneer-style setback halfway there.  Nevertheless, the probe has already broken altitude records.  Moreover, the craft weighs almost 800 pounds, dwarfing anything we put up in 1958.  The U.S.S.R. clearly has a new rocket, and it's a doozy.

Interestingly, the Soviets have been rather cagy as to the exact purpose of this probe.  Is it supposed to impact the moon?  Is it supposed to enter lunar orbit, as was the intention of the American Pioneers?  Or will it just fly by?  All Moscow will say is, "The multi stage cosmic rocket has gone out according to its program on the trajectory of its movement in the direction of the moon."  The excerpt below doesn't clarify much either, though it does sound ambitious:

The Soviets have announced that Mechta is carrying a similar slew of experiments to that carried on the Air Force Pioneers.  These experiments are designed to investigate the intensity of magnetic fields around the Earth and moon, as well as the space in-between.  They include a magnetometer, a geiger counter, a scintillation counter.  There is also a micrometeorite detector on board.  One has to wonder if these instruments are any better than the ones lofted in Pioneers 0-2; while they weigh an order of magnitude more, this may well be because the Soviets are behind us in miniaturization technology.  On the other hand, it may be that the satellite is carrying a secret payload–perhaps there is another dog on board, or maybe a flea circus.

Lunik has made its mark on history already, however–literally.  I am told that the probe released a cloud of sodium gas late last night when it was about a quarter of the way to the moon.  I can think of two reasons for this.  Scientifically, it allows us to determine the effects of the space environment on clouds of sodium gas.  Politically, it proves that the Soviets actually did send a probe to the moon, their news outlets having skewed somewhat left of complete honesty in the past few decades.

So stay tuned.  By January 5th, I shall either report to you of the triumphant success of the first Soviet lunar shot or of its failure.  If the latter be the case, at least it will be in good company.

America SCORES! (12-22-1958)

Unless the Soviets can pull a rabbit out of their hat, it looks like the United States will come out the winner in the Space Race for 1958.

It was only a matter of time before we finally used our Atlas rocket, the nation's first Intercontinental Ballistic Missile (ICBM), to launch a satellite.  With the Atlas, we can finally throw up payloads of similar weights to those launched by the Soviets with their ICBM.

The first Atlas mission, Project SCORE, was launched on December 18, 1958.  It is the heaviest payload ever to be launched by the United States into orbit—a whopping 8000 pounds' worth!  That compares favorably to the 9000 pound payload launched by the Soviet Union in May (Sputnik III).  Of course, those figures are a little less impressive when one realizes that the vast bulk of that weight actually comprises the last stage of the rocket.  Moreover, Sputnik III carried over a ton of instrumentation.  SCORE carries a bare 150 pounds of payload.

What SCORE does, however, is unprecedented.  Quite simply, it is the world's first communication's satellite.

Currently, if one wishes to send a message across the country or the world, one must either use archaic transoceanic cables or, more frequently, send the signal via some sort of radio.  The former method puts strong limits on destination (messages can only go where the cables are strung), and the latter is only as reliable as the atmosphere will allow.  Reception at remote locations is virtually impossible.  But with a satellite, one truly has the high ground.  Messages can be beamed anywhere along the satellite's line of sight, which is essentially limitless. 

Developed jointly by the Air Force and veteran communications company, RCA, SCORE has the ability both to broadcast messages as they are beamed to it from ground stations and to store received messages and transmit them later.  Seeing how it was an Air Force mission, there were probably plenty of classified messages sent and re-transmitted, but the one everybody got to know about was this one, recorded by President Eisenhower the day after launch:

"This is the President of the United States speaking.  Through the marvels of scientific advance, my voice is coming to you from a satellite circling in outer space.  My message is a simple one: Through this unique means I convey to you and to all mankind, America's wish for peace on Earth and goodwill toward men everywhere."

Once again, science fiction has become fact.  Arthur C. Clarke predicted communications satellites in the '40s, and here we are at the dawn of a new era. 

If that era comes.  It must be cynically pointed out that this launch had a second purpose—to show the Soviets that we, too, have the ability to send a nuclear bomb 6,000 miles across the globe.  While this represents a technological achievement and another example of science fiction become fact, I somehow can't be as excited about this development.  It is yet another reminder that, thus far, the exploration of space has been primarily a military endeavor, and our plowshares are barely modified swords.

Oops, Part 4 (12-08-1958)

Well, at least we're consistent.

The past few months, the newspapers have run headline after headline describing America's failures in trying to shoot the Moon.  The Air Force had the first at-bat with its three Pioneers.  #0 blew up so early that it wasn't even dignified with a name.  #1 limped about halfway to the Moon before falling back down.  #2's performance was somewhere in the middle.

If you believe the papers (and/or the Vice President), all of these flights were successes.  After all, any launch, even one that doesn't meet its goals, is a learning experience.  Sarcasm aside, Pioneers I and II were not total washes–they sent back a lot of good data on the Earth's magnetic field and the radiation trapped therein.  Moreover, they went a lot higher than any of our previous probes, certainly higher than anything the Russians have sent up.

The day before yesterday (Dec. 6, 1958) was the Army's chance to step up to the plate.  If hitting the Moon is a Home Run, I'd say they hit a double.  Pioneer III, a teeny 13-pounder launched on a Juno II made it out about 67,000 miles before falling back to Earth.

As always, I collected as many papers as I could and kept my ears glued to the radio.  Early editions simply announced the launch, but it was clear pretty quickly that something had gone wrong.  Apparently, Pioneer's rocket ran out of fuel about four seconds early, which sent the probe off at too low an angle.  Even though Pioneer III left Earth with more speed than Pioneer I, its journey was only half as high.  38 hours after launch, the poor little probe was ashes in the ionosphere. 

Silver lining: A good 22 hours of data was collected from the probe, and it is already adding to our knowledge regarding the two (count them: two!) radiation belts girdling the Earth.  As a matter of fact, those belts are the only phenomenon Pioneer III could report on.  Unlike Pioneers 0-II, which had a whole suite of experiments including even a TV camera, Pioneer III had just one experiment: a pair of Geiger-Muller tubes for counting the cosmic radiation particles hitting the spacecraft.  I am not sure why Pioneer III was such a simple probe.  It may be that the Army got the assignment in a hurry and had to rush things.  It might also be that the Army's Juno II doesn't have the enough strength to lift anything heavier.

In any event, this isn't the last we'll be hearing from the Army.  Pioneer IV will be up sometime soon, though Major General John Medaris, head of the Army's rocket development center in Alabama, had no firm dates for the press.

"See me after Christmas," he told the television people.

Get a load of that puss.  That looks more like a toothache than a booster failure. 

Here's an interesting question: The Space Race has been marked by more failures than successes.  Did anyone ever write a science fiction story that predicted this level of teething pain in a space program?  It seems to me that space vehicles in fiction simply work.  If they don't work perfectly, they have maintenance issues like those that afflict an automobile or perhaps a naval vessel.  This goes back to my previous comments regarding the focus of science fiction on the pilot rather than the large and necessary logistical tail. 

It's a pity we don't see more stories incorporating launch failures.  They could be an exciting dramatic device.

What's in a name? (12-4-1958)

I'm still waiting for my January F&SF to show up, so here's another topical scientific post.  Just call me Willy Ley's poor cousin.

The space stories in today's newspapers are filled with a mixture of alphabet soup and Roman mythology.  Keeping track of what's what can be a headache.  For instance, there has been a lot of confusion regarding the naming of the rocket that launched Explorer I (and III and IV, and tried to launch II and V).  Some accounts called it a Jupiter-C.  Others have since called it a Juno I.  Which is correct?  Is there a Jupiter missile somewhere in there?  Does it even matter? 

Let me clear things up.  The answer shines an interesting spotlight into the politics of naming and the jockeying for position being done by this country's armed services.

Back in 1953, Von Braun and his Alabama team of German expatriates finished the first significant rocketry development since the V2 (which they had also built).  It was the Redstone Medium Range Ballistic Missile (MRBM) with a range of more than a hundred miles.  Von Braun knew he had a vehicle that was powerful enough to send something into orbit, and he lobbied heavily for his "Project Orbiter" so that he, and the Army, could launch the first artificial satellite.  He lost that fight to the Navy, who started work on the Vanguard, based in turn on the Viking sounding rockets, which were based on the V2.

Nevertheless, Von Braun did win the contract to build the longer-ranged successor to the Redstone, the Jupiter Intermediate Ranged Ballistic Missile (IRBM).  This let Von Braun keep Project Orbiter alive, at least under wraps.  The first step toward turning the Redstone into a satellite booster was a series of test launches with Jupiter IRBM components on board.  He called the resulting machine "Jupiter-A," even though at its heart, it was really a Redstone.  This helped ensure launch pad availability, since the Jupiter was a higher-priority program.

Then he added 11 miniaturized solid-rocket boosters called Sergeants (descendants of the WAC Corporal rocket, of course) as a second stage and one more as a third stage.  This new booster was used as a sounding rocket, probing the outer reaches of the atmosphere in short suborbital flights, and was called the "Jupiter-C."  I don't know if there were ever plans for a "Jupiter-B."

Once Sputnik was launched, America was hard-pressed to make a quick response.  Von Braun trotted out the Jupiter-C, all ready to launch a payload.  It wasn't quite enough to get Explorer I into orbit, however, so another mini-Sergeant was attached to the satellite and placed on top of the Jupiter-C third stage.  This technically made the Jupiter-C a four-stage rocket, even though one could argue that the fourth stage was really part of the payload. 

It was important that there be little connection between the military space programs and the civilian space programs, at least in the press.  That's why Vanguard was given the nod for the first satellite launch.  While it was developed by the Navy, it was run under the auspices of the civilian National Research Laboratory.  Jupiter-C was renamed "Juno I" to distance the rocket from its military origins.

It was not a very successful move.  Contemporary newspapers universally referred to the rocket as the Jupiter-C (which, of course, it was).  The name "Juno I" is only now common in retrospective use, as its last flight was on October 23.  It is a useful distinction, however, as Von Braun has taken the 2nd, 3rd and "4th" stages from the Juno I and affixed them to a true Jupiter IRBM, thus creating the "Juno II."  This new vehicle should have about the same lifting capacity as the Air Force's Thor-Able, maybe a little less.  It will launch Pioneer III next week.  Note: Pioneer III has nothing to do with Pioneers 0-II save that they have the same destination, the moon.

All clear?

The short flight of Pioneer II (11-13-1958)

Sometimes the third time isn't the charm.

On November 8, NASA (read: The Air Force), sent the third of its “Pioneers” toward the moon.  For those following the topic, the first one, launched in August, exploded.  The second one, launched last month, strayed from its intended course and made it just halfway to its destination.

There were high hopes for this mission: the new little Pioneer had a couple of new instruments including a proportional counter developed by the University of Chicago for the detection of cosmic rays, and a TV camera designed to take the first picture of the Moon from space. 

Sadly, Pioneer II (the first one was “0”, hence the misnomer), didn't make it either.  Though the first and second stages worked perfectly, the third one simply refused to fire.  The little Pioneer limped up to an altitude of 1550 kilometers before burning up over Africa.  It was an inauspicious ending for the world's ninth space shot, but it was not entirely in vain.  I understand Pioneer II returned some interesting data on micrometeors and orbital radiation.  It will be interesting to compare this information to that collected by Explorer IV and see how they line up.

So where do we go from here?  It seems STL, builder of Pioneers 0-2, has shot its bolt for now.  Von Braun's group has announced that it will be launching its own lunar Pioneers starting next month, and that Venus is in the cards as a destination in the near future.  The Soviets surely have their secret plans, too.  In fact, I have to wonder why the Russians haven't already launched a lunar rocket.  On October 12, a Soviet ambassador congratulated us for launching Pioneer I and explained that the Communists weren't interested in a moon probe.  But four days later, the Soviets hinted that a moon probe was in the works.  Perhaps they are having their own failures, but they are unwilling to share this news with the world. 

In any event, it is clear that the moon marks the end of the next lap in the ongoing Space Race.  Watch this space for further updates as they occur. I may not be as punctual as David Brinkley, but I am better-looking.

Things to Come (10-31-1958)

These are exciting times we live in.  The drop in published science fiction is (almost) made up for by the increase in space-related articles in my newspaper.  I read an Associated Press piece yesterday that I thought was particularly interesting:

"NEW YORK (AP) Colonies of Earthmen will occupy the Moon, Mars and Venus.  Rockets will be burning their way toward the outer planets, more than three billion miles from Earth.  Engineers will fashion huge space transports, capable of carrying hundreds, perhaps even thousands, of people on space expeditions that may last most of a lifetime.

These are among the predictions for the next 25 years — the coming generation — made yesterday at a panel of nine space experts in astronautics, the journal of the American Rocket Society.

These experts were agreed that the Earth would soon be ringed with satellites and space stations… Huge rockets would roar between continents carrying cargo and passengers in minutes."

The panelists included Dr. York, chief scientist for the Advanced Research Projects Agency (ARPA), Dr. Hugh Dryden, deputy administrator at the newly formed National Aeronautics and Space Administration (NASA, formerly NACA), Dr, Si Ramo, President of Space Technology Laboratories, and Dr. Wehrner von Braun, who had a minor rocketry position during the War and has since gone on to greater things with the U.S. Army.

Now is this a mainstream recognition that science fiction is becoming science fact?  Or is this merely the wishful thinking of a bunch of folks whose business, frankly, is making a living off space travel? 

Are they the same thing?

Either way, there is no question that bigger and better things are just around the corner.  Dr. Dryden opines that there will be people in orbit in just a few years.  Von Braun outlined a 2nd and 3rd generation of rockets in development that will ultimately throw up to 50,000 pounds into orbit at once! 

I know that the Redstone-based Juno I, the famous booster that launched America's first satellite (Explorer I), was retired last week after failing to launch Explorer VI.  Its replacement will have the same upper stages but will be based on the much-larger Jupiter missile.  I don't know if that rocket will be big enough to put a person in orbit, but I'll bet something based on the new Atlas ICBM could do it.

And it's pretty clear that the Soviet rocket that put the ton-and-a-half Sputnik III into space could do it.  Of course, I'm not sure where they'll get the volunteers to fly in the thing if its anywhere near as balky as our rockets have been.  If the first Russian satellite was Sputnik, and the second was Muttnik (because it carried a dog cosmonaut), I'm guessing the first manned ship will be called "Nutnik." 

It may well be that the first person in space won't ride a cannonball but a spaceplane.  I clipped from the paper on October 16th a picture of the Air Force's new aircraft, the X-15.  It's a beautiful ship made by the same people who built the P-51 and the F-86.  It's supposed to fly at Mach 6 or 7 and go up as high as 50 miles above the ground.  Vice President Nixon (remember him?) said of the craft, "We have moved into first place in the race to enter outer space." 

We'll see how long we stay there.

One year after Sputnik (10-21-1958)

On October 4, 1957, the world was stunned by the beep-beep of the first artificial satellite.  Well, maybe stunned is the wrong word, because anyone following the papers throughout the summer saw that the Soviets had announced quite candidly that they had planned to do so. 

It didn't take long for good ol' American know-how, like that provided by good ol' Americans like Wehrner Von Braun, to match the Russians at their game.  Thus, Explorer 1 went up less than three months later. 

Given the promptness of the American reply, one has to wonder if Ike wanted the first satellite to be Soviet…

Last week, if you followed the presses, American took the lead in the Space Race, at least for the time being.  Pioneer-1 blasted off on October 11.  Destination: Moon.

Sadly, the intrepid probe didn't quite make it.  Still, it traveled a good half of the way there, and it returned some pretty interesting science on the way, piercing Van Allen's dangerous clouds of radiation that may pose a permanent barrier to humankind ever establishing an orbital presence. 

I understand that a second Pioneer is scheduled for launch next month.  I'm crossing my fingers and toes!
