Last of the First

MA-9. the final Mercury flight

Last year, my erudite buddy Brian Fies and I were discussing (via blogs) that the next few years were going to be chock-a-bloc with 50th anniversaries of the Space Age. May 15th, 2013 marks yet another golden anniversary - - this time an ending, rather than a beginning.

Mandatory image of all manned Mercury launches

The Mercury 7 astronauts were the trailblazers of the American space program. In just six flights (Deke Slayton was sidelined with a heart murmur), the Mercury astronauts tested their vehicles, their navigation skills, and even their own bodies as lone pilots in space.  Although NASA moved ahead with construction of the Gemini two-man vehicle and the Apollo moonship, the results of the Mercury program's flight data would shape all manned space programs to come.

Alan Shepard rode his Mercury craft in a parabolic suborbital flight lasting just fifteen minutes. John Glenn's first orbital flight lasted just a little over four hours. As the Mercury mission continued, the flight durations lengthened.

By May of 1963, NASA felt ready to attempt a 24-hour flight in space. Preparations for such a long-duration mission required the removal of the ship's periscope to provide room for extra oxygen tanks and batteries to power the instruments.  To offset the weight of the extra batteries, redundant attitude thrusters were removed from the nose of the ship.  NASA engineers decided that since the primary thrusters had proven reliable, backup thrusters were no longer necessary.

Cooper was the first American astronaut to be seen
on video, live from space.

Just after 8:04am on May 15, 2013, astronaut Gordon Cooper's MA-9 spacecraft Faith 7 lifted off from Cape Canaveral. Cooper had a full plate of experiments to run through in this mission: tracking a blinking ball that was jettisoned overboard during the first orbit, examining atmospheric drag effects on a tethered balloon trailing the spaceship, collecting blood and urine samples after trying a variety of foodstuffs to see if there were any problems metabolizing things like powdered roast beef or chocolate brownies. The experiments resulted in varied levels of success: Cooper spotted the blinking ball, the balloon never deployed, Cooper didn't open the brownies out of fear that floating crumbs would damage the instruments.

The astronaut managed to doze off for several orbits as the first day in space drew to a close. With his ship powered down to conserve fuel and electricity, Faith 7 drifted lazily along its prescribed path. On the 30th orbit, the first signs of trouble with the ship popped up - - a small panel light indicated that the ship detected a minute change in the g-forces that would signal the beginning of reentry.

Cooper believed the signal was an instrumentation flaw, and ground controllers confirmed that there had been no change to the orbit. During the next orbit, the situation began to deteriorate rapidly. The main circuit buss for the instrument panel shorted out, knocking all navigation controls offline. Cooper was left with a radio, his wristwatch, and his eyeballs to navigate his 17,500 mph ship.
 

Mission accomplished

Fortunately, NASA had trained Cooper for just such an emergency. In contact with John Glenn at the Mercury Control Center, Cooper twisted manual thrust knobs on the sole attitude control system and aligned his retrorockets using a visual gauge on the ship's porthole aimed at the horizon of the Earth. With his stopwatch, Cooper called out a countdown that matched the calculations Glenn had passed up to him from ground controllers. Cooper opened a manual valve as the countdown reached zero, and his three retrorockets fired. Less than twenty minutes later, Faith 7 was bobbing in the Atlantic Ocean, only 4.4 miles from the recovery ship Kearsarge,  -- the closest landing of any Mecury spacecraft to its intended target.

Gordon Cooper would be the last American to launch into orbit by himself, and, until Dave Scott became Command Module Pilot of Apollo 9 in April of 1969, the last American to pilot his own spacecraft in orbit by himself. Project Mercury ended, and was soon eclipsed by the greater challenges of the Gemini missions. May 15th, 1963, though, was the end of America's first tentative steps into space.

A House in Space

An amazing machine, despite all its difficulties.

Forty years ago, I lived about fifty miles north of New York City, in a little town just far away enough from Manhattan for the light pollution to dim and for the Milky Way to shine in the night sky. I didn't know many kids in town as I had just moved there over the previous Christmas, so I spent a lot of time in the evening just enjoying the brilliant stars overhead.

The Moon missions were over. With the cancellation of Apollos 18-20, I didn't think there would be another lunar landing until after I was out of high school. On May 14th, the final Saturn V would launch NASA's Skylab orbital workshop into space. I managed to talk a guidance counselor at my school into letting me watch the launch on a school TV during lunch time. It looked like this:

 

After the Saturn disappeared into the cloud deck, horrible things started to happen. The micrometeroid shield running the length of the converted S-IV-B stage sheared off the side of the lab, yanking one of the extensible solar panels with it.  The remnant cables of the missing solar panel coiled around the ship, knotting over the other solar panel and preventing its deployment. It would take two of the three planned missions to repair the Skylab enough for it to do many of the experiments for which it was designed.

Despite the near-disaster at launch, Skylab proved to be a remarkable workshop. By the end of the program, the United States had gained an 84-day record of continuous habitation in space. Many of the lessons learned would be put to use decades later on both Shuttle missions and in the construction of the International Space Station.

There's lots of minutiae to talk about in the history of Skylab but I just wanted to mention something I experienced with my own eyes. Before the first crew arrived at the station at the end of May, 1973, there was a detailed series of articles in the New York Times about what had gone wrong with the ship, and what the plan for the repairs would be. At the end of the article, there was a list of viewing times in the NY area for spotting both Skylab and the S-II Saturn stage that had pushed the ship into orbit. I remember standing in my front yard in the darkness, waiting to see if anything would be visible in the night sky.

Suddenly a dim bead of light appeared from the southwest, followed by another, much brighter light traveling at about the same speed. The S-II was slightly ahead of Skylab, as it was continuing in a slightly lower (and therefore faster) orbit. I had never seen two objects orbiting the Earth at the same time, and it struck me that this would probably be a common sight when I was older, as the sky filled with many orbiting Shuttles and stations.

I was wrong about the number of ships I'd see, but I was correct that I'd see multiple ships in space at the same time in my old age. By 2009, I was living in Massachusetts, and I remembered the Skylab flyover from so many years ago as I watched the Space Shuttle Discovery maneuver to dock with the International Space Station.

The ISS outshines the accomplishments of Skylab in just about every way, but Skylab's pioneering experiences (both operationally and in its repair) made the later achievements of the ISS possible.

"Поехали!"

Yuri Alexevich Gagarin
First Man in Space

It was a political act. It had little to do with piloting. It was a dangerous stunt that almost cost a man his life, but it was the moment that began all manned spaceflight that followed. Fifty-two years ago today, Yuri Gagarin was strapped into an eight-foot-wide, aluminum-alloy sphere and launched into Earth orbit.

Gagarin was a tiny fellow, barely 5' 2". He was assigned the mission mostly because he didn't add much to the payload of the automated spacecraft. Sergei Korolev, the Chief Designer of the Soviet space program, said a final command to him before Gagarin climbed into the spacecraft: "Come back."

The ship Gagarin rode into space was called Vostok, which means "East" but also carries the idea of "Dawn" - - the beginning of a new day. The Vostok wasn't originally designed as a crewed spaceship - - Korolev's engineers based its construction on the requirements for a reconnaissance satellite, capable of hoisting several hundred pounds of cameras, lenses, and film into orbit. The ship was supposed to counter the American Corona project, which was already returning miles of photographic intelligence about Soviet air bases back to the CIA. Korolev managed to tack on the manned aspect of Vostok as a selling point to the Soviet politburo, who liked the secondary role for what it was: a great tool for propaganda about "space exploration," while concealing Vostok's primary purpose as a spy ship.

Because Vostok's chief purpose was for unmanned missions, the control and operation of the ship was entirely automatic. A cosmonaut's role as pilot, then, was superfluous. Korolev worried about "interference" by pilots during flight, so the onboard controls were locked down with a password. As a compromise between the designers and the flight controllers, the ship carried a sealed envelope containing the manual override code. Cosmonauts were forbidden to open the envelope without approval from the mission operators back on Earth. I'm not exactly sure how they would stop a cosmonaut from opening the envelope.

Launch Day

On the morning of April 12th, 1961, Yuri Gagarin rode a bus to the base of the R-7 rocket that would launch his Vostok into the sky. He saluted Korolev, shook hands with several ground support personnel, and then climbed a ladder up to the Vostok's hatch. The ground team screwed on the hatch, and then needed to remove and reseat the hatch when they noticed it hadn't quite sealed properly. At 8:07am local Baikonur Time, the twenty engines of the R-7 Semyorka booster ignited, and Gagarin's ship lifted off the pad. He shouted "Поехали!" ("pyoucali!" or "Let's go!") into his microphone as the ship cleared the launch site.

Six minutes after launch, both the boosters and the protective cover around Gagarin's ship separated from Vostok 1. The cosmonaut's first opportunity to view the Earth from space revealed a cloud-covered morning over central Russia. "I can see the Earth. The visibility is good. I can almost see everything. There's a certain amount of space under the cumulus cloud cover," he reported back to Baikonur before flying out of radio range.

Unlike the American network of ships and ground stations spread across the world, the Soviet program had only a small group of ships scattered along Gagarin's intended flightpath. With limited data being returned to the control site, Korolev's people weren't sure if Vostok was in a stable orbit for nearly a half hour after launch.

Things were equally mysterious for Gagarin. Since he had only a few instruments to inform him about his ship's status, Gagarin could only rely on whatever information the ground controllers could radio to him during the brief moments when they were in touch via the relay ships. As he flew within communications range of a radar station in southeastern Siberia, Gagarin asked,  "What can you tell me about the flight? What can you tell me?" The station radioed back that they had nothing to report and that Korolev (code-named "Number Twenty") had no instructions for him. Vostok-1 continued its flight as it headed down the length of the Pacific Ocean.

At the half-way point over the Straits of Magellan, the Vostok attitude control system identified the Sun rising in the eastern sky. The ship aligned itself for retrofire, arming the service module's sole remaining engine. Korolev's mission designers had an unusual backup plan in the event of the rocket's failure during reentry: the selected orbit would decay naturally in 7-10 days, so they loaded Gagarin's crew module with a week's worth of food and oxygen to wait out the "organic" landing mode.



Fortunately, the retrorocket ignited successfully, chopping the orbital parameters to intersect with a ground track down to Siberia. Immediately after retrofire, though, came the mission's greatest failure. The service module containing the navigation and propellant equipment failed to detach from the descent sphere. As the upper atmosphere began to buffet the two modules, the sphere began to whip around the service module at an ever-increasing rate. Gagarin was experiencing more than 8 g's of lateral force, compounded by the deceleration effects of the atmospheric reentry. Ground controllers lost contact with the ship as it passed over Egypt. They wouldn't be able to communicate until the Vostok ship passed through the ionization layer.

The buffeting snapped the connection between the service and descent modules, and Gagarin's ship managed to right itself to deploy the ship's parachute. As the ship approached an altitude of 23,000 feet, the cosmonaut ejected from the descent module, just as cameras and film would be jettisoned on unmanned reconnaissance missions. Gagarin descended separately from his ship because Korolev's spacecraft designers couldn't figure out how to build a parachute capable of landing both payload and ship safely. It was an embarrassing compromise for Korolev, and this aspect of the mission plan was kept from the West for decades.

In the Saratov region of western Siberia, two farm girls saw a pair of parachutes descending overhead. A man suspended by one of the parachutes landed on a nearby hill. Dressed in an orange suit with a large white helmet, the farm girls began to back away as he approached. They had heard about the American pilot Gary Powers and didn't want to be involved with another spy pilot. "Don't be afraid!" yelled Gagarin, lifting his visor. "I'm Russian!" Gagarin's  25,000 mile flight ended on a Siberian farm a little more than an hour and a half after it began.


Fifty two years later, the world celebrates the birth of manned spaceflight with Yuri's Night, a series of parties and star-gazing that anyone is free to join in and participate. Although Americans tend to ignore the achievements of other nations in space, this is truly an international event to appreciate. Gagarin's quick jaunt into space motivated Americans to reach for the Moon, and built the foundation for the world's cooperative program: the International Space Station. Go and enjoy Yuri's Night tonight, and think about the little guy who took that first flight.

We had Everything in the World Drop Out

Here's a sad thought: as of 2010, more than half the country was not yet alive when America landed on the Moon. Folks my age, the people who witnessed the Apollo missions, are the exception, not the rule.

As such, the Apollo missions are a matter of remote history, consigned in popular culture to the same ranks of historic ignorance as the War of 1812 or the life of William H Taft.

Historical trivia: Tom Hanks didn't go to the Moon
with Kevin Bacon and Bill Paxton.

Surveyor 3 was the first spacecraft to
purposefully dig a trench on the Moon.
That doesn't include all the spacecraft that accidentally
dug a trench on impact.

Most people have a poor understanding of the history of Apollo. Their limited knowledge is derived almost exclusively from motion pictures such as Ron Howard's Apollo 13, a movie that, while accurate in most details, left behind a general idea that the only Bad Thing that ever happened on the way to the Moon was the Apollo 13 mission. The movie also gave the impression that Apollo astronauts were merely helpless passengers on a deep space journey, constantly hoping and praying that ground crews would come up with ideas to rescue them.

In fact, NASA's astronauts were not only veteran test pilots, but skilled aeronautical engineers, capable of diagnosing complex electrical systems and flight navigation software. The mission immediately prior to Apollo 13 put these myriad skills to the test in a life or death situation, just moments after launch. And the entire near cataclysm was witnessed by no less an audience than the President of the United States, 43 years ago on November 14, 1969.

The Apollo 12 mission was designed to be the first manned lunar landing with a precise target destination in mind. Unlike Armstrong and Aldrin's goal of merely landing on the flattest part of the Moon, astronauts Pete Conrad and Alan Bean would aim for a 300 square yard touchdown zone near the landing site of the unmanned Surveyor 3 spacecraft. The mission would test the limits of the crew's navigating and piloting skills, as well as the hardware's computing and event handling abilities.

Cmdr. Pete Conrad was arguably the best choice to lead this mission. The veteran naval aviator and test pilot had previously crewed the long-duration Gemini 5 mission, as well as the Gemini 11 Agena docking mission, a flight that briefly made Conrad and copilot Richard Gordon record holders for having traveled farthest from planet Earth. Conrad was a comedian and a prankster, but he also had a reputation for keeping a cool head and working through problems, even during the most dire emergencies. He was reliable when situations were no longer "nominal."

Don't disappoint the President.

Launch weather on the morning of Apollo 12's scheduled liftoff was hardly nominal. An advancing front had pushed a low cloud deck over Merritt Island during the evening, and set visibility conditions at the brink of flight rule acceptability. Unfortunately for NASA, politics sometimes trumped caution. President Richard Nixon, Chief Executive of the United States and holder of the Pen of Budget Appropriations Approval was in town for the launch that day, and to disappoint someone who was in charge of deciding the future of the agency would be an unwise move. So, despite the dodgy weather, the all-Navy crew was loaded into the 365-ft tall Saturn V and the countdown continued in the rain.

At T-0:00, with 7.5 million pounds of thrust, Apollo 12 thundered off the launch pad into the clouds. Just thirty seconds later, the ship would go transonic, pushing through maximum aerodynamic pressure inside the storm.

Launch commit... liftoff!

 Thirty six and one half seconds into the flight, the Something Bad part happened. Here's a transcript:

000:00:37 Gordon (onboard): What the hell was that?
000:00:38 Conrad (onboard): Huh?
000:00:39 Gordon (onboard): I lost a whole bunch of stuff; I don't know.

What happened was that a bolt of lightning seared through the clouds and the spacecraft, riding the trail of rocket vapor back to the launch pad. A second bolt of lightning repeated the journey a few seconds later.

000:00:50 Gordon (onboard): I can't see; there's something wrong.
000:00:51 Conrad (onboard): AC Bus 1 light, all the fuel cells-
000:00:56 Conrad (onboard): I just lost the platform.

Conrad was looking at a mess on his control panel. Every possible alarm signal was lit. The entire electrical system, previously being powered by fuel cells in the Apollo Service Module, seemed to be out. The navigation system (the pilots' familiar 8-ball) was spinning endlessly in a useless gimbal lock. And still the ship hadn't exploded... yet. Either the alarms were wrong or they were about to experience the first out-of-control Moonship. Conrad briefly explained the situation to Mission Control.

000:01:02 Conrad: Okay, we just lost the platform, gang. I don't know what happened here; we had everything in the world drop out.

Gordon, the Command Module Pilot, didn't think it was a hardware problem, but he wasn't sure what to do about the instrumentation problem.

000:01:09 Gordon (onboard): I can't - There's nothing I can tell is wrong, Pete.

000:01:12 Conrad: I got three fuel cell lights, an AC bus light, a fuel cell disconnect, AC bus overload 1 and 2, Main Bus A and B out.

This was no way to get to the Moon. Apollo 12 hadn't reached orbit yet - - they still were low enough to use their Launch Escape Tower and abort the mission. Conrad fingered the abort handle on the arm of his chair and pondered options.

Artist - astronaut Al Bean's interpretation of that moment.

 In the right-hand seat, Lunar Module Pilot Al Bean noodled through the dials on his side of the ship. Bean spotted a voltage indicator from the fuel cells that showed there was still energy in the system.  
000:01:21 Bean (onboard): I got AC.
000:01:22 Conrad (onboard): We got AC?
000:01:23 Bean (onboard): Yes.
000:01:24 Conrad (onboard): Maybe it's just the indicator. What do you got on the main bus?
000:01:26 Bean (onboard): Main bus is - The volt indicated is 24 volts.

Twenty four volts wasn't enough to run the mission, but it also meant that the electricity might be shorting out somewhere in the panel or in one of the circuits. The question was how to isolate the electrical problem without detonating the tons of fuel just behind them that was in the process of shoving them toward the Moon.
  

EECOM and veteran chain smoker John Aaron.

In Houston, a  NASA physics major named John Aaron suddenly realized this scenario was somewhat familiar. Aaron was the Electrical, Environmental and Consumables Manager (EECOM) for this flight, and he had seen a launch problem like this during a mission simulation back in 1968. The problem was that the primary equipment used to convert hardware electrical loads to power levels that could be read by the monitoring dials (known as "signal conditioning equipment") was broken. Fortunately, Apollo was equipped with backup, auxiliary equipment. Aaron knew the problems with all the different system alarms could be fixed with the flick of a switch. Aaron keyed his microphone to talk to CAPCOM Gerry Carr. "Try SCE to AUX," he said.

Astronaut CAPCOM Gerry Carr had no idea what that sentence meant. Neither did Flight Director Gerry Griffith, serving as Flight Director on his very first mission. "Tell them that," he told Carr.


000:01:36 Carr: Apollo 12, Houston. Try SCE to auxiliary. Over.
000:01:39 Conrad: Try FCE to Auxiliary. What the hell is that?
000:01:41 Conrad: NCE to auxiliary...

Carr corrected Conrad:

000:01:43 Carr: SCE, SCE to auxiliary.

Conrad also never heard that command before this mission. Fortunately, Al Bean knew what they were talking about. Bean had been part of the same simulation run that John Aaron remembered, and knew where the switch was on the many confusing panels of the Command Module. Al turned the switch, and the control panel reset itself. 

000:01:48 Bean (onboard): It looks - Everything looks good.
000:01:50 Conrad (onboard): SCE to Aux.
000:01:52 Gordon (onboard): The GDC is good.

Guidance and telemetry were back online, or rather, the astronauts were now able to see what Guidance and telemetry was trying to tell them. Conrad didn't have to pull the abort handle and stop the mission. Immediate crisis averted, they finally had time to take in what had just happened:
000:06:43 Gordon (onboard): Man, oh man ...
000:06:44 Bean (onboard): Isn't that a ...
000:06:45 Conrad (onboard): Wasn't that a Sim[ulation] they ever gave us?
000:06:46 Gordon (onboard): Jesus!
000:06:50 Conrad (onboard): [Laughter].
000:06:51 Gordon (onboard): That was something else. I never saw so many...
000:06:52 Conrad (onboard): [Laughter].
000:06:54 Gordon (onboard): ...There were so many lights up there, I couldn't even read them all.
000:06:55 Conrad (onboard): [Laughter].
000:06:57 Gordon (onboard): There was no sense reading them because there was - I was - I was looking at this; Al was looking over there ...
000:07:02 Conrad (onboard): Everything looked great [laughter] except we had all the lights on...

High-speed  launchpad cameras revealed the twin lightning strikes
that nearly wrecked the mission.

An amazing, terrifying moment that could have easily ended in failure, or tragedy. Instead, the training and skill of the crew and support staff managed to avert disaster. Oh, and they did manage to land right next to that Surveyor spacecraft just five days later.

Mission Accomplished

A Fistful of Redstones

Fifty-one years ago today, on October 27th, 1961, the largest flying machine ever built by Wernher von Braun's rocket scientists to date smashed into a million pieces two hundred and fourteen miles southeast of Cape Canaveral. This event marked a veritable victory lap for von Braun's team, and also signaled the end of a technological battle between two branches of the United States military.

Don't you love stories that start out this way? I know I do. Let's back up a bit and go over the details.

Military Missiles

After the end of World War II, the three major branches of the military were crazy for establishing missile superiority - - not with other countries, but between the other branches of the US military. The Army led the development race, building Inter-Regional Ballistic Missiles (IRBMs) such as the Redstone and Corporal rockets under the guidance of von Braun's Peenemuende team. The Air Force, denied the benefits of Operation Paperclip, built their own Goddard-derived rockets in the Atlas and Titan series. The Navy, having no budget for a big missile development program, concentrated on their tiny Vanguard missile program.

Picking the next generation of missiles was a matter of using what worked already.

 The success of von Braun's Jupiter rocket after the failure of the Vanguard rocket as a response to the launch of Sputnik put the Army's Redstone / von Braun team in the prime position to build future heavy-lift launch vehicles. The main restraint was that there was still a branch limitation on long-distance rocketry. The Army could still build interregional rockets, but the Air Force's Ballistic Missile Division was the only organization allowed to negotiate for boosters capable of intercontinental or orbital reach. Even after the Redstone group was assigned to the civilian NASA organization, the Air Force restrictions stood in place.

Wernher von Braun's team knew that the next generation of heavy lift vehicles would require multiple stages - - but the upper stages would have to be designed with the mandates of the Air Force in mind. Since upper stages would probably need to be designed around the Air Force's Titan booster, the next generation of the Army's first stage would need to be able to accommodate the Titan's 120-inch wide frame.

What von Braun's team didn't know was that the Air Force was working on a secretly-designed second stage named Centaur. Centaur would be fueled with liquid hydrogen (LH2), the most efficient fuel known to rocket scientists. The problem with LH2 is that although it's efficient, it's not very dense, so the requirements for fuel tank sizes would be significantly larger than the original planned Titan upper stages. In order to accommodate the Centaur upper stage, the von Braun team's new first stage would need to support a 160" diameter frame.

The USAF Centaur was also supposed to power the X-20 Dyna-Soar space glider.

The Huntsville team managed to rework the design of their heavy lift booster to meet the new requirement by wrapping eight Redstone tanks around a central Jupiter tank assembly. The new vehicle, first named Juno V and then Saturn I, would launch with eight Rocketdyne H-1 engines capable of delivering a total thrust of 1.5 million pounds of force. The eight Redstone tanks, plus the Jupiter core were known technologies, so redesigns of new tanks and feed mechanisms weren't necessary. The slight weight disadvantage of multiple tanks had a tremendous offset in multi-year development costs that were avoided.

Wrap a Jupiter rocket with eight Redstones? That's a Saturn I.

 

 Barging In

 The Huntsville rocket scientist slapped together a Saturn I booster in no time, and ready for launch in early 1961. A static test at the Redstone Arsenal broke windows eight miles away from the test stand. The booster was too large to be transported by rail, so the Saturn would travel by barge to Cape Canaveral. In a pre-GPS world, the barge ran into some literal snags, as nautical maps were not accurate enough to note sand bars and shallows along the Gulf Coast route. After un-beaching the barge on several occasions, the Saturn I arrived at Pad 34 in August of 1961.

Heading for Cape Canaveral aboard the barge Compromise. Managed to beach itself four times.

One downside of the Huntsville crew's speed in construction was that the Air Force's upper stage (now called the S-IV) was nowhere near launch-ready in its development process. NASA decided to build a dummy upper stage, filling the large empty tank with water ballast equal to the proposed weight of the S-IV.

A working S-IV upper stage wouldn't be available for launch until 1964.

 On the morning of October 26th, 1961, the launch operations crew filled the nine tank assemblies with RP-1 kerosene and liquid oxygen. The only delay in the entire process was a brief hold for clouds and winds that would affect photography. After a one-hour delay, all holds were cleared, and the folks in the blockhouse ignited the eight solid propellent gas generator (SPGG) motors, that fired the liquid fuel pumps and started the H-1 engines. Saturn SA-1 lifted off the Pad 34 "milk stool" and headed out over the Atlantic, reaching an altitude of 84.6 miles only four minutes and nine seconds later. The water ballast accelerated to 3,611 mph before falling back to the ocean in an arc that stretched two hundred miles from Cape Canaveral.

We have liftoff, 27 October 1961, 12:30pm ET

Except for an early engine cutoff due to an underfilling of the tanks, the flight was flawless. The von Braun team displayed a mastery of heavy lift launch systems that would not be superseded by the Air Force ballistic missile group in building the way to the Moon landings.

After the success of SA-1, Saturn was the only way to the Moon for JFK.

 Pad 34 would become the initial platform for Apollo-Saturn development flights, and would provide key data for the follow-on Saturn V Moon ships. And all that work began fifty-one years ago today.

You can visit Pad 34 today on the Kennedy Space Center tour. The milk stool still stands.

Worth a thousand words

It's October 24th, so let's celebrate another space history anniversary.

War as a technology driver is an axiom, and no war seemed to drive technology as much as World War II. The atom was split to defeat Japan, radar technology was mastered to intercept German bombers over Britain, and a host of medical treatments, from antibiotics to skin grafts, were developed to save the lives of soldiers, sailors, and civilians.

Rockets, of course, also made a technological resurgence during World War II. Their absence  from the battlefield (apart from their cousins, the mortars) was due to their ineffectiveness in the War of 1812. Except for being excellent terror weapons (so much so, we turned a song about rockets into our national anthem), rockets did little damage to targets on the ground.

Wernher von Braun and his team of rocket scientists changed all that. Following in the developmental footsteps of American scientist Robert Goddard, von Braun's team created a continuously-improved collection of liquid-fueled missiles in the mid-1930s called the Aggregat series. Aggregat-1 was a 4-foot-tall rocket with a gyroscope in the nose, and incorporated Goddard's turbo-pump ideas to move fuel into the engine. The second group of Aggregat rockets were fully operational and flew in test launches to altitudes over a mile high. The A3 series, although never successfully launched, incorporated both a stabilizing gyroscope, plus two additional "steering" gyroscopes that manipulated thrust vanes placed in the path of the rocket exhaust.

Dr. von Braun, at right, explaining rocketry to his customer base.
"Nazi, Shmatzi," says Wernher von Braun.

Then came the A4, or as the Nazis named it, Vergeltungswaffe 2 (Vengence Weapon 2), or V-2. The V-2 was huge - over 45 feet tall, and capable of carrying a 500-lb. payload 55 miles into the sky, and then hit a target 200 miles away at more than four and a half times the speed of sound. It wasn't very accurate, but the speed and the magnitude of the destruction where it landed was a significant advancement in rocket warfare. By the time World War II ended, three thousand V-2s had killed over seven thousand military and civilians on the ground.

After the war, the United States military snapped up von Braun's rocketeers in Operation Paperclip, shuffling the German rocket scientists off to the desert of White Sands, New Mexico. Here, in what the license plates call the Land of Enchantment, von Braun's scientists were given access to the captured equipment from their V-2 days, and instructed to build follow-on missiles with extended range and payload-carrying abilities.

I thought the V2s were all black-and-white, but many were in yellow jacket color schemes.

Among the captured V-2 equipment were entire, unfired V-2 rockets. The Germans tinkered with the war machines, recalibrating the gyroscopes and aligning the rocket vanes to carry the payloads to higher altitudes.

On October 24th, 1946, the thirteenth post-war V-2 was launched in a near vertical configuration. Inside the nose of the rocket, a 35mm motion picture camera was bolted next to an inspection porthole and aimed perpendicular to the direction of travel. A steel ball bearing in a tube leaned against a lever that sat atop the camera's shutter release. When the engine thrust ceased after 45 seconds, the ball bearing (and everything else in the ship) would experience zero gravity, and would no longer be pressing down on the lever. The shutter clicked at an altitude of 65 miles, and this is the first image created by that action:

High over New Mexico

The camera took another picture every 1.5 seconds for the rest of the trip, as the V-2 coasted up to an altitude of 107.5 miles before falling back to Earth. The ship pranged into the desert floor a few minutes later, destroying the rocket and the camera, but leaving the sturdy frame of the film cassette unscathed.

Before the launch, the most distant photos of Earth were taken from balloons at an altitude of 13 miles. This mission moved that record to an altitude five times the previous height. This photo, showing the curvature of the Earth, and taken from the edge of space, can easily be considered the first photograph of the Space Age.

Sigh.

I now have the official, required Library of Congress copyright investigation complete so that the Long-Forgotten Movie can be digitally duplicated.

Except, well (using Facebook relationship status-ese) -- it's complicated.

The investigator discovered that, yes, the Famous Rocket Company applied for a copyright, but that was for an *unpublished* work - - almost a year after they donated the film to the Not Very Famous Museum. The museum had already shown the film to close to THREE MILLION cash-paying visitors, so it was hardly "unpublished" anymore. By the timeline, the Famous Rocket Company was trying to copyright a work it had already given away. Based on this history, the Library of Congress researcher declared the film's copyright "questionable."

The Famous Rocket Company listed the Famous Director as "author" but since it's a work-for-hire, that probably takes care of the Famous Director part of the copyright claim equation. 

I feel like an astronaut with a bad comb-over,desperately trying to pry open a VHS tape with a butter knife before re-entry.

So now, the only remaining hurdles are getting something called a "quit-claim" from both the Famous Rocket Company and the Not Very Famous Museum. I've already written to the Famous Rocket Company, asking them to please dismiss their invalid copyright application, so that I can help the Library of Congress preserve this film. If (and yes, that's a huge "if") I can get that particular piece of paper, I'm going to ask the Not Very Famous Museum to do likewise, as they've already thrown out their only copies of the film and they've obviously shown no interest in saving this film anyway. My guess is that the museum is going to take a much longer time to resolve, as no one there seems to want to be in charge of legal matters like copyrights.

It's going to be a long summer. Hope for the best.

I'm writing a book based, in part, on my Master's thesis. Since it's going to be a commercial book, and since there's a chance the subject is actually fascinating, I can't talk about too many details.

Let's use generic phrases so I can talk to you about one part of the research for this book. A long time ago, a Rocket Ship Company hired a Famous Director to make a movie about rocket ships. The Rocket Ship Company donated the movie to a Not Very Famous Museum.

Next, the Rocket Ship Company submitted a copyright notice to the US Copyright Office. Meanwhile, the Rocket Ship Company didn't notice that the Famous Director had put a copyright notice ("copyright (c)Famous Director") under the title of the movie - - right *in* the movie! 

Later on (but still back in the 1970s) the Not Very Famous Museum decided to toss the movie (and all materials related to the movie) into a dumpster. The only existing, complete copy of the film resided at the Library of Congress vault in Culpepper, Virginia.

Decades fly by, and now it's 2012, and I want to get a digital copy of this Library of Congress copy of the movie to finish writing my book. In order to get a copy of this movie (by a Famous Director), I'll have to pay several hundred dollars for a transfer to HD video. But FIRST... I have to determine: who holds the copyright?

Turns out there are agencies in and around the Copyright Office who handle this kind of stuff. So I hired a copyright private eye to figure it all out.

Here are the possible scenarios:

1) The film has no parents - so it's an orphaned film in the public domain (best thing evarrr!)

2) The Rocket Ship Company holds the copyright - could be okay, because I know some people who run the Rocket Ship Company's museum and maybe they'll sign a quitclaim for me. Hooray!

3) The estate of the Famous Director (in this case, a University library) - could be HUGE trouble, because the folks who work at the University archive think everything the Famous Director made must be worth MILLIONS, I tell ya! MILLIONS! (possible worst-case scenario).

4) Not Very Famous Museum holds the copyright - unlikely (they never filed with the Copyright Office) but if they get ownership, it's going to be a big problem because nobody, and I mean NOBODY there understands the slightest thing about quitclaims or intellectual property or making decisions about stuff they didn't know they had. I think I worry about this one more than Option 3.

So, hopefully I'll have a handle on this by Friday. If not, it'll be a very long weekend.
