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

Leave a comment

One Step

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

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

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


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

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

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

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

No News is…

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

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

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

Coming Attractions

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

But hope springs eternal…  See you then!

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

2 Comments


by Gideon Marcus

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

Two for the Price of One

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

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

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

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

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

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

Destination Unknown

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

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

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

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

The Balloon Goes Down

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

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

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

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

2 Comments


by Gideon Marcus

Baby's first step… Take Four

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

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

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

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

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

A breath of very thin fresh air

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

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

Until now. 

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

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

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

The Cosmos opening up for Kosmos

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

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

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

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

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

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

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

[March 24, 1963] Bumper Crop (A bounty of exciting space results)

5 Comments


by Gideon Marcus

February and March have been virtually barren of space shots, and if Gordo Cooper's Mercury flight gets postponed into May, April will be more of the same.  It's a terrible week to be a reporter on the space beat, right?

Wrong!

I've said it before and I'll say it again.  Rocket launches may make for good television, what with the fire, the smoke, and the stately ascent of an overgrown pencil into orbit…but the real excitement lies in the scientific results.  And this month has seen a tremendous harvest, expanding our knowledge of the heavens to new (pardon the pun) heights.  Enjoy this suite of stories, and tell me if I'm not right…

How hot is it?

Mariner 2 went silent more than two months ago, but scientists are still poring over the literal reams of data returned since its rendezvous with Venus.  The first interplanetary mission was a tremendous success, revealing a great deal about the Planet of Love, whose secrets were heretofore protected by distance and a shroud of clouds. 

Here's the biggie: Preliminary reports suggested that the surface temperature of "Earth's Twin" is more than 400 degrees Fahrenheit.  It turns out that was a conservative estimate.  In fact, the rocky, dry landscape of Venus swelters at 800 degrees — possibly even hotter than the day side of sun-baked first planet, Mercury.  It's because the planet's dense carbon dioxide atmosphere acts like a heat blanket.  There's no respite on the night side of the hot world either; the thick air spreads the temperatures out evenly.

Thus, virtually every story written about Venus has been rendered obsolete.  Will Mariner 3 destroy our conception of Mars, too?

Just checking the lights

On February 25, the Department of Defense turned little Solrad 1 back on after 22 months of being off-line.  The probe had been launched in conjunction with a navigation satellite, Transit, back in June 1960.  For weeks, it had provided our first measurements of the sun's X-ray output (energy in that wavelength being blocked by the Earth's atmosphere and, thus, undetectable from the ground).  DoD has given no explanation for why the probe has been reactivated, or why it was turned off in the first place.  Maybe there's a classified payload involved?

Radio News from the Great White Spacecraft

Last September, the Canadians launched their first satellite — the "top-sounder," Alouette, whose mission was to measure the radio-reflective regions of our atmosphere from above.  The results are in, and to any HAM or communications buff, its huge news.

It turns out that the boundaries of the ionosphere are rougher at higher latitudes than at lower latitudes.  Moreover, Alouette has determined that the Van Allen Belts, great girdles of radiation around our planet, dip closer to the Earth at higher latitudes.  This heats up the ionosphere and causes the roughness-causing instability. — the more active the electrons, the poorer the radio reflection.  Now we finally know why radio communication is less reliable way up north.  The next step will be learning how to compensate for this phenomenon so that communication, both civil and military, can be made more reliable.

Sun Stroke Warning

After a year in orbit, NASA's Orbiting Solar Observatory is still going strong, with 11 of 13 experiments still functioning.  The satellite has probably returned more scientifically useful data than all of the ground-based solar observatories to date (certainly in the UV and X Ray spectra, which is blocked by the atmosphere).

Moreover, OSO 1 has returned a startling result.  It turns out that solar flares, giant bursts of energy that affect the Earth's magnetic field, causing radio storms and aurorae, are preceded by little microflares.  The sequence and pattern of these precursors may be predictable, in which case, OSO will give excellent advance warning of these distruptive events.

Tax money at work, indeed!

Galaxy, Galaxy, Burning Bright

In the late 1950s, astronomers began discovering some of the brightest objects in the universe.  It wasn't their visible twinkle that impressed so much as their tremendous radio outbursts.  What could these mysterious "quasi-stellar sources" be?

Now we have a pretty good guess, thanks to a recent scientific paper.  Cal Tech observers using the Mt. Wilson and Mt. Palomar observatories turned their gaze to object 3C 273, a thirtheenth magnitude object in the constellation of Virgo.  It turns out that 3C 273's spectrum exhibits a tremendous "red shift," that is to say, all of the light coming from it has wavelengths stretched beyond what one would expect.  This is similar to the decrease in pitch of a railroad whistle as the engine zooms away from a listener.

The only way an object could have such a redshift is if it were of galactic proportions and receding from us at nearly 50,000 km/sec.  This would place it almost 200,000,000 light years away, making it one of the most distant (and therefore, oldest) objects ever identified.

At some point, astronomer Hubble's contention that the universe is expanding is likely to be confirmed.  These quasi-stellar objects ("quasars"?) therefore represent signposts from a very young, very tiny universe.  What exciting times we live in!

Five years of Beep, Beep

St. Patricks Day, 1958 — Vanguard 1 was the fourth satellite in orbit, but it was the first civilian satellite, and it is the oldest one to remain up there.  In fact, it is the only one of the 24 probes launched in the 1950s that still works.

What has a grapefruit-sized metal ball equipped with a radio beacon done for us?  Well, plenty, actually.  Because it has been tracked in orbit so long, not only have we learned quite a bit about the shape of the Earth (the variations in Vanguard's orbit are due to varying gravities on the Earth, the measurement of which is called "geodetics"), but the satellite's slow decay also tells us a lot about the density of the atmosphere several hundred miles up.

So, while Sputnik and Explorer might have had the first laughs, Vanguard looks likely to have the last for a good long time.

Telstar's little brother does us proud

RCA's Relay 1, launched in December, is America's second commercial communications satellite.  It ran into trouble immediately upon launch, its batteries producing too little current to operate its transmitter.  Turns out it was a faulty regulator on one of the transponders; the bright engineers switched to the back-up (this is why you carry a spare!), and Relay was broadcasting programs across the Atlantic by January.  660 orbits into its mission and 500 beamed programs later, NASA announces that Relay has completed all tests. 

Nevertheless, why abandon a perfectly good orbital TV station?  Relay will continue to be used to transmit shows transcontinentally, especially now that Telstar has finally gone silent (February 21).  There is even talk that Relay could broadcast the Tokyo Olympics in 1964, if it lasts that long!

In a sea of Blue, a drop of Red

On March 12, 3-12 at the Spring Recognition Dinner of Miracle Mile Association, in Los Angeles, Cal Tech President, Lee DuBridge, noted that the United States has put 118 probes into space, while the Russians have only lofted 34 (that we know of).  He also pointed out that virtually no scientific papers have resulted from the Soviets' "science satellites." 

As if in reply, on March 21 the Soviets finally, after 89 days without a space shot, launched Kosmos 13.  (To be fair, it's been kind of quiet on the American side, too).  The probe was described as designed to "continue outer space research."  No description of payload nor weight specifications were given.  Its orbit is one that allows it to cover much of the world.  While it may be that some of the Kosmos series are truly scientific probes, you can bet that, like America's Discoverer program, the Kosmos label is a blind to cover the Russians' use of spy satellites.  Oh well.  Turnabout is fair play, right?

[July 29, 1962] What a Diff'rence a Month Made (July 1962 in spaceflight)

12 Comments

[if you’re new to the Journey, read this to see what we’re all about!]


by Gideon Marcus

Sometimes, the future comes so fast, it bewilders.

This rushing feeling I've had all month must be similar to what my grandparents felt when the Wright Brothers first took off.  For millennia, people have dreamed of flight, envying the birds.  Yet flying was always the province of make-believe, of fanciful stories.  Then, on one day in 1903, airplanes became a reality, and the world was transformed.

Ditto space travel.  That dream has been alive since the Ancient Greeks, yet it was entirely a theoretical concern until the Soviets pierced the heavens with their first beeping Sputnik.  It is easy to forget, now that there have been well over one hundred successful orbital missions, that just five years ago, there had been none.

The advances made just this month are tremendous, each one as significant as the breakthroughs I've just detailed.  Let's review:

Ma Bell, Orbital Division

Unless you've been living under a rock the last few weeks, you can't have missed virtually non-stop coverage of the first civilian communications satellite, AT&T's Telstar.  Launched July 10, it circles the Earth every 90 minutes; for 20 minutes of every orbit, North America and Europe are linked via the dappled spheroid.

Now, it's not as if the two continents had been completely cut off before.  However, the only way to communicate was via undersea phone line (expensive, not useful for television), or shortwave radio (no pictures).  If the UK wants to watch reruns of The Twilight Zone, or if we wanted to see airings of Danger Man or Supercar, we have to wait for videotapes to be shipped/airmailed across the Pond.  News from abroad is often days out of date.

That's about to change.  Starting with a fairly humdrum broadcast of a flag in France, Telstar's programming has now included a host of shows including a Presidential address and a sports match.  And everyone can receive them (so long as the local stations rebroadcast the feed).  Over the next few years, expect satellite coverage to become continuous.  Arthur C. Clarke's dream of comsats fixed in the sky, 22,500 miles overhead, will soon become a reality, and the world shall be connected as never before.

Jousting Space Shutterbugs

Since April, the Soviets have been orbiting a series of disparate probes under the unified designation, "Kosmos," the latest being Kosmos 7, which launched yesterday.  Details on these flights have been sketchy, and while they are all billed as scientific missions, it is beyond doubt that some or all of them have been spy satellites.  I infer this based on the fact that at least one of them was deorbited and recovered a few days after launch – the same modus operandi as our Discoverer film-return satellites.

Speaking of which, yesterday we launched the 47th in the Discoverer series.  As usual, the Air Force did not announce the flight, but it was in the papers anyway.  It's really hard to hide a rocket launch in the middle of California.

It is unlikely that the two satellites took pictures of each other, but wouldn't that be a snapshot to develop?

Getting to Space the Old-Fashioned Way

Until this month, the only way into the deep black was at the tip of a rocket, as Messrs. Shepard, Grissom, Glenn, Carpenter, Gagarin, and Titov can attest.  But on July 17, Major Robert White flew his X-15 rocket plane to an altitude of 59 miles.  For NASA, that's close enough to outer space to count, and they're giving the Major a pair of astronaut wings to wear on his flight suit. 

White experienced three minutes of weightlessness during his flight, and the stars were brilliant and unwinking at the journey's apex.  While this is close to the highest the X-15 can ever fly, it strongly suggests that, in the not too distant future, the next generation of spaceplanes will zoom into orbit from a conventional runway.

Just try not to live right under the take-off point.  That could get loud.

Bits and Pieces

The Apollo moonship design is moving right along.  One lingering question, however, was how the thing would get to the moon.  After all, it is the heaviest manned spacecraft yet developed.  The original concept involved building a giant version of the already giant Saturn booster.  This eight-engine monster is dubbed Nova, and it would take Apollo directly to the moon.  Appropriately, this mode is called "Direct Ascent."

A cheaper idea involves using two Saturn C-5s (a simpler, 5-engine variant), one carrying the Apollo, and the other carrying the fuel.  The two would meet in Earth orbit before jetting off to the moon.  This mode is called "Earth Orbit Rendezvous."

But it was the plucky underdog idea that was ultimately chosen this month.  Called Lunar Orbit Rendezvous, it requires just one Saturn C-5.  At its tip will be an Apollo, some fuel, and a teeny Lunar Excursion Module (or LEM).  The Apollo, itself, won't land on the moon.  Instead, two astronauts of the three will cram into the LEM for the landing. 

This mode was, at first, deemed too complicated to be practicable.  Computers are getting better these days, however, and the cost savings are significant.  Moreover, there's less to go wrong with one rocket than two.

I'm wholly in favor of this move.  After all, anything with the acronym LEM must be incredible.

Conquered by (the Planet of) Love

The one bit of sad news accompanies the loss of Mariner 1, our first planned mission to Venus.  Launched on July 22, its Atlas Agena rocket, the biggest one we've got right now (save for the still-in-testing Saturn 1), glitched during take-off and had to be destroyed five minutes into the flight.

Unlike Pioneer 5, which two years ago flew to Venus' orbit and demonstrated the possibility of long-range telecommunications, Mariner 1 would have flown by the planet, itself.  It would not have been able to take pictures; the Atlas Agena combination isn't powerful enough to lift a spacecraft with a big enough radio to send scans of photos.  We'll have to wait for the beefier Atlas Centaur for that.

Instead, Mariner 1 is really a retool of the first generation of Ranger moon probes, carrying a slew of particle and electromagnetic wave detectors.  If an "R-type" Mariner makes it to Venus, we won't get a look under the planet's shroud of clouds, but we will, at least, finally know hot the world is and get some information on its magnetic field.

The good news?  Mariner 2 is scheduled for launch next month.  Let's hope that one works – otherwise, we'll have to wait another year and a half for Earth and Venus to be in favorable position for a mission.

Live via Visi-Phone!

Courtesy of Telstar and the miracle of Visi-phone(tm) technology, the Journey had a smashing second Tele-Conference on July 29, covering a wide range of topics: from news of the day, to discussion of the upcoming Hugo Awards, to talking about this Summer's blockbusters.

If you missed the live broadcast, catch the rerun.  Check your local listings for details.

Congratulations go out to Mark Yon and Nathan "Rocky" Anderson for asking the best questions!  You can expect your prizes to arrive over the next few weeks.  And to the rest of our audience, warm thanks from the Galactic Journey staff.  We look forward to seeing you again when we do our third Tele-Conference in 2-3 months.

In the meantime, enjoy this revolutionary new era.  The future is only going to come more quickly, I predict…

[Apr. 30, 1962] Common Practice Period (April Spaceflight Round-up)

7 Comments


by Gideon Marcus

The radio plays Classical music on the FM band now. 

The difference is palpable.  Bach and Mozart on the AM band were tinny and remote.  It was almost as though the centuries separating me and the composers had been attenuating the signal.  This new radio band (well, not so new, but newly utilized) allows transmissions as clear as any Hi-Fi record set could deliver. 

Don't get me wrong; I still listen to the latest pop hits by The Shirelles and The Ventures, but I find myself increasingly tuned into the local classics station.  The sound, and the selections, are just too good to ignore.  The last movement of Robert Schumann's Symphony #1, with its stirring accelerando is playing right now, and it is a fitting accompaniment for the article I am currently composing.

Time was I would write an article on a space mission about once a month.  This wouldn't be a wrap-up, but an article devoted to a single satellite.  But the pace of space launches has increased – there were two successful orbital flights in 1957, nine in 1958, 13 in 1959, 20 in 1960, 38 in 1961.  There were six flights just last week.  Either I'm going to have to start abbreviating my coverage, or I'll need to start a satellite (no pun intended) column. 

But that's a decision for next year.  Right now, with a bit of musical texturing, let me tell you all about the exciting things that happened in spaceflight, April 1962:

Quartet in USAF Minor

Late last year, President Kennedy put a lid on all military space programs, classifying their details.  This was a break from Ike's policy, which was to publicize them (more or less accurately).  I think Eisenhower's idea was that any space shot was good for prestige.  Also, if we were upfront about military flights, maybe the Soviets would follow suit.

The current President has decided that discretion is the better path.  So even though I have it on good authority that four boosters took off from Vandenberg Air Force Base in California (it being rather hard to hide a blast of that magnitude, and the papers are still reporting on them as best they can), I couldn't tell you exactly what was at the tips of those rockets.  It's a fair bet, however, that three of them were reconnaissance satellites, snapping photos of the USSR from orbit.  The last was probably a nuclear missile launch detector called MIDAS.  That's make it the 5th in the series. 

Quartet in USSR Minor

Meanwhile, the Russians, who had not reported any spaceflights since Comrade Titov's flight last summer, suddenly threw up four probes in about as many weeks.  The missions of "Kosmos" 1-4 were "to study weather, communications, and radiation effects during long space flights in preparation for an eventual manned landing."

That sounds good, but while the first three satellites are still up in orbit returning scientific data, the fourth, launched four days ago, landed three days later – after passing over the United States several times.  All we know about it was it was launched from "a secret base" and "valuable data [was] obtained."  Given that Kosmos 4's mission plan bore a striking resemblance to that of our Discoverer capsule-return spy sats, I suspect the first three Kosmos shots were a flimsy camouflage.  What's interesting here is that the Communists feel it necessary to construct a cover-up.  But the fact is, they just can't hide when they launch things into space, any more than we can. 

Solo for English Horn

The first UK satellite, Ariel 1, was successfully launched on April 26, 1962 atop an American Thor Delta booster.  The little probe will investigate the Earth's ionosphere.  You can read all about this mission in Ashley Pollard's recent article.

Mooncrash Sonata

It's two steps forward, one step back for NASA's ill-starred ("mooned?") Ranger program.  Thrice, the lunar probe failed to fly due to a balky Atlas Agena booster.  This time, Ranger 4, launched April 24, 1962, was hurled on a perfect course for the Earth's celestial companion.  The trajectory was so perfect that the craft didn't even require a mid-course correction.

Of course, it wouldn't have mattered if it had.  Upon leaving the Earth, it quickly became apparent that Ranger 4 was brain-dead.  It issued no telemetry, nor did it respond to commands.  NASA dispiritedly tracked the probe's 64-hour trip to the moon, which ended in its impact on the far side. 

Heart-breaking, but it is a sort of semi-victory: At least the rocket works now, and the United States as finally caught up with the Soviets in another aspect of the Space Race (just two-and-a-half years late…)

Saturn (fortissimo)

Speaking of successful rockets, the tremendous Saturn I had another successful test on April 25, 1962.  Like the first, the upper two stages were inert, filled with water for ballast.  This flight has a twist, however.  After the first stage had exhausted its fuel, the dummy stages were detonated and the ensuing watery explosion observed.  This "Operation Highwater" was designed to demonstrate how far the debris of a booster blast would travel.  I imagine it was also a lot of fun.

I have to wonder about the future of the Saturn I.  It has already been determined that the Apollo moon craft will be launched by the much more powerful and generally unrelated Saturn C-5 and Nova boosters.  It seems that the Saturn I is something of a technological dead end, though I'm sure they are at least perfecting their heavy booster launch techniques.

Prelude, Symphony #2

The National Aeronautics and Space Administration is planning another Mercury one-person shot for next month.  It will be an exact duplicate of John Glenn's February flight, down to the three-orbit duration.  To be piloted by Navy aviator Scott Carpenter (the hunkiest of the Mercury 7), the main purpose of the mission is to make sure that the errors that plagued Glenn during his flight are fixed before the little spacecraft takes on longer journeys.  And, of course, then we will have caught up with the Russians in another way – we'll have had two men orbit the planet.

No doubt, Carpenter's flight will be the spaceflight highlight of next month; I have not seen any other missions announced.  Then again, the Reds might have a surprise that'll have us singing a different tune…
