And the stars look very different today

The Internet is agog with the release of Canadian astronaut Chris Hadfield's video cover of David Bowie's "Space Oddity" - - a musical interpretation filmed almost entirely onboard the International Space Station.



Hadfield is seen floating in the Tranquility module's cupola, the Japanese Kibo module, and the hatchway to a waiting Soyuz spacecraft. A  unattended, velcro-studded guitar spins languidly through the station, while Hadfield sings lyrics of a space pilot surrounded by technology, viewing a Universe beyond all imaginings.

When people think about the "importance" of manned space flight, it's usually about having someone on hand to repair broken equipment and second-guess computer errors far from home. The true reason people are in space, I believe, is for moments such as this video. We need people in space to interpret and humanize the exploration so that we, as a planet, can share the experience. Folks like Chris Hadfield take the known (a Bowie song, a guitar, a piano) and show us the unknown (looking out the window and seeing a planet) with the reference point of our culture. It's why everyone remembers Alan Shepard's golf shots on the Moon during Apollo 14. It's why we still watch archival footage of Dave Scott and Jim Irwin driving the first lunar rover across the Moon's surface during the Apollo 15 trip. It's even why Ron Howard made the Apollo 13 movie - - when something goes wrong in space, the only time we really care is if there are people onboard.

Hopefully, someday before the centennial of human spaceflight, a human being will make a cover video of David Bowie's "Life on Mars?" -- from the surface of that planet. Certainly another cultural moment everyone on our planet will enjoy.

"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.

Thirty Pounds of Science

Previously on Citizen O'Kane, I wrote about how the Soviets beat the United States into orbit because President Eisenhower didn't want to win the Space Race on the shoulders of a reconstituted Nazi V-2 missile. The von Braun team, based in Huntsville at the Redstone Arsenal, were forced to cripple their experimental rockets with payloads of sand instead of propellant, just to make sure a competing Navy Vanguard program would get dibs on the first orbital mission.

After the October 4th, 1957 launch of the Soviet Sputnik satellite, all bets were off. Vanguard was nowhere near ready to be launched, and the Department of Defense gave the go-ahead to von Braun's rocket men to gear up for a launch as soon as possible. No more sand-bagged fourth stages, no more launch azimuths ending in the South Atlantic - - this time, the destination was Earth orbit.

The back half was just a rocket motor that wasn't jettisoned,
out of concern it might bang into the payload in orbit.

The folks on the von Braun team also wanted to make the payload more than just a beeping radio transmitter. The goal needed to be science related to make the project more than just a stunt. Fortunately, a payload group at the California Institute of Technology's Jet Propulsion Lab (under the direction of Dr. William Pickering) had been working on a satellite design for several years. The 30-lb satellite, powered by an experimental mercury battery and built with some of the first transistors ever manufactured, would carry out several experiments once in orbit.

Some of the more intricate experiments were designed by Dr. James Van Allen of the University of Iowa. Dr. Van Allen incorporated a cosmic ray counter and a geiger counter to track the elusive celestial energy particles that were rarely detectible at sea level. Due to the lack of space on the satellite, Dr. Van Allen omitted a data recorder, which eliminated continuous observations except when the satellite passed over a receiving station. The results from these observations were erratic and unexplained, until Dr. Van Allen made the remarkable discovery that massive magnetic bands emanating from the poles seemed to deflect most of the rays. The bands, now called the Van Allen Belts, are probably the greatest discovery of the early Space Age. The Belts reshaped our basic understanding of how Earth's magnetic field  - - they're why life can continue on the planet without being destroyed by celestial radiation.

All that previously unknown information became possible 55 years ago this evening, when von Braun's Juno booster hoisted Pickering's satellite with Van Allen's experiments into their first orbital mission. And we haven't stopped exploring since that evening.

Downmass

The word "stevedore" has a great heritage. It comes from the Spanish word "estevador," for "one who stuffs things." Being a stevedore was an occupation for many people working at seaports, where loads of cargo needed stuffing into the holds of freight ships.
Stevedores getting ready to stuff the stuff in with the other stuff on the ship.
 The job of stevedore shouldn't be confused with that of the longshoreman. Longshoremen unload freight ships, stacking the cargo on docks for delivery to warehouses. It's a different skill set, and actually made for two distinct unions during the 19th and 20th Centuries.

Most of us have only a cinematic understanding of  modern dock operations. We think not much has changed since the days of On the Waterfront, where burly, Vic Taybeck-looking guys would offload a ship full of wooden crates with hand-held freight hooks and hemp rope hoists.
If containerized shipping had been established in the 50's, maybe Lee J. Cobb
wouldn't have gotten into that big fist fight with Marlon Brando on the Hoboken docks.


The world's moved on, though. Since 1969, when the US Department of Defense established a standard size for containerized freight, a revolution in cargo transport has changed every job at ports throughout the world. Gone are the days of guys shoving wooden crates into excelsior-lined hulls. Today, the roles of both stevedore and longshoreman have been combined into that of crane operators, a mechanical method of loading and unloading ships without requiring a bunch of guys to crawl all over the cargo. While the number of folks employed by the dockside industry has declined, the amount of merchandise and material shipped worldwide has grown exponentially, expanding employment in related fields such as logistics, transportation, and warehousing.
Today: less Elia Kazan movies, more Denny's Claw games

All this leads up to something going on in outer space next week. On October 7th, SpaceX will launch the first production mission of its Dragon cargo ship to the International Space Station. The previous launch of Dragon was an experiment to see if the process would work - - this time, the cargo is for real.
SpaceX Dragon: this time, it's professional.


Why are the Dragon missions so important? Besides being the precursor to future manned American trips to the ISS, the Dragon is unique among its cargo-carrying rivals (Europe's ATV, Japan's H-III, and the stalwart Russian Progress modules) in that it not only can bring cargo to the ISS, but also bring equipment back to Earth. The other cargo ships are built for one-way trips. They don't have heat shields, parachutes, or any method of surviving re-entry. Even the manned ship, Soyuz, is only capable of returning less than 110 lbs of station equipment back to Earth, and that would only be small things that could fit through the Soyuz's narrow 27-inch hatch.
Puny 27" Soyuz hatch.

Dragon, by comparison, is a proverbial supertanker of downmass cargo. Instead of using the Soyuz probe-and-drogue connector, or even the Shuttle's old PMA linkup, the hatch to Dragon connects directly with any available Common Berthing Mechanism (CBM) port, which allows for a full 50-inch pass through width for equipment. H-III and ATV also use the CBM ports, but as I said before, they can't bring anything back home. The Dragon's downmass capacity (6,614 lbs) equals half the amount it can carry into orbit (13,228 lbs); in fact, this first production ship is going to bring more down than it carries up.
Un-be-freakin'-lievable 50" Dragon CBM hatch.
 How is this such a game changer? Simply, because it's brought the return of downmass capability to ISS operations back to the station program that's been missing since the retirement of the Shuttles last year. Experiments that didn't fit through Soyuz's tiny hatch, or weighed more than 110 lbs were stuck in orbit or doomed to fiery destruction in the old one-way cargo ships. Dragon, built specifically to accomodate the standard ISS experiment rack, makes possible the completion of dozens of station experiments that can now be studied back on Earth. Equipment is now capable of making round trips, so expensive, disabled hardware can be returned to Earth, repaired, and sent back into orbit on a future freight run - - all at a cost about 1/100th of a Shuttle mission.
Round-trip ticket, baby.


A dozen cargo missions by Dragon are scheduled for next year, followed by manned Dragon missions six months to a year after that. The routine-ness and simplicity of Dragon missions will finally make ISS missions safer and more affordable. Like its ocean-going counterpart, the two-way containerization of space cargo will change the economics of space -- for the better.

Not Because They are Easy, but Because They are Hard

Nuno Bettencourt was the lyricist and frontman for the 80's rock band, Extreme. He wrote lots of glam metal rock ballads, but achieved his greatest success with an acoustic pop song.

Bettencourt felt that the phrase "I love you" was becoming meaningless. In a 1991 interview with the Albany Herald, he said, "People use it so easily and so lightly that they think you can say that and fix everything, or you can say that and everything's OK. Sometimes you have to do more and you have to show it – there's other ways to say 'I love you.'"  The result was the hit song More Than Words.

True, words can be meaningless if not backed up with actions, but sometimes words spark and inspire enormous actions.

Today marks the 50th anniversary of a speech that defined and explained the reasons why America decided to go to the Moon. President John F. Kennedy, speaking to a class of future engineers and scientists at Rice University, stood at a podium in the middle of a football stadium on a hot September morning and summarized the history and mission of American explorers. The scope was huge, covering 50,000 years in the first two minutes of the speech, then continuing through the period from the establishment of the Plymouth Bay Colony by William Bradford, and extending to the investigations of the Moon and the planets beyond which continues a half-century later.

Historians can point to a handful of Presidential addresses that encapsulate a moment in time clearly and succinctly. Abraham Lincoln, penning thoughts about the dedication of a national cemetery, summarized the reasons for the Civil War and its higher purposes in the 262 words that form the Gettysburg Address. Franklin Roosevelt, responding to a surprise attack by an enemy on the other side of the planet, formulated a speech that marked the Pearl Harbor assault as a "day of infamy" forever.

The Rice University speech by President Kennedy is undoubtedly on a par with these other historic addresses. JFK spoke not only to the Rice students, but to America and the world:

William Bradford, speaking in 1630 of the founding of the Plymouth Bay Colony, said that all great and honorable actions are accompanied with great difficulties, and both must be enterprised and overcome with answerable courage.
The simple idea here is that going to the Moon is nothing new - - Americans have worked on tough projects before, and will do so in the future. Tying the Space Age to the founding of the country explained this new reach to the unknown as a familiar habit for the nation.
 If this capsule history of our progress teaches us anything, it is that man, in his quest for knowledge and progress, is determined and cannot be deterred. The exploration of space will go ahead, whether we join in it or not, and it is one of the great adventures of all time, and no nation which expects to be the leader of other nations can expect to stay behind in the race for space.

Those who came before us made certain that this country rode the first waves of the industrial revolutions, the first waves of modern invention, and the first wave of nuclear power, and this generation does not intend to founder in the backwash of the coming age of space.
 Remember, at the time of this speech, the Soviet Union was far ahead of America in manned spaceflight. They had spent more than several days in space - our three manned orbital flights totaled less than 12 hours. The sense of behind-ness rankled the nation.
We mean to be a part of it--we mean to lead it. For the eyes of the world now look into space, to the moon and to the planets beyond, and we have vowed that we shall not see it governed by a hostile flag of conquest, but by a banner of freedom and peace. We have vowed that we shall not see space filled with weapons of mass destruction, but with instruments of knowledge and understanding.
Kennedy continued the comparison between our conflict with the Soviets on Earth, and the new, unconquered frontier of space:
There is no strife, no prejudice, no national conflict in outer space as yet. Its hazards are hostile to us all. Its conquest deserves the best of all mankind, and its opportunity for peaceful cooperation that may  never come again.
The President then put out the Big Questions of the thesis:
But why, some say, the moon? Why choose this as our goal? And they may well ask why climb the highest mountain? Why, 35 years ago, fly the Atlantic?
On the trip into Houston - - realizing his audience -- Kennedy penciled in an additional Big Question:
Why does Rice play Texas?
And then he answered those questions with an epic response that will probably be quoted as long as Americans travel into space:
We choose to go to the Moon.
We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard.
Because that goal will serve to organize and measure the best of our energies and skills, Because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too. 
 Bettencourt was right that actions are more important than words. But I think, sometimes, the words matter, too.

Space Pedantry

I apologize: I'm a nitpicker. I'm pedantic, to use the crossword puzzle term. Little things make me twitch like Herbert Lom in the Pink Panther movies.

Nothing gets me more nitpicky than errors in space reporting. People who write technical articles about space are supposed to simplify explanations so that the general public can understand matters of orbital mechanics and engineering, but it doesn't mean that the writers need to be inaccurate.

My latest twitchiness revolves around the COTS-2 Dragon spacecraft, due to meet up with the International Space Station on Friday. Dragon is a history maker, being the first commercial cargo ship to arrive with a billable payload for the ISS.

Where does the craziness erupt? It's when TV reporters describe the linking as "docking" the spacecraft to the station. It's not a docking. In fact, avoiding a docking situation is exactly why the Dragon is such an attractive ship to both NASA and the other space station partners. Dragon has been built specifically NOT to dock with the station.

Docking is when a ship under its own power connects with another ship. Think of a boat on the water as it pulls up to, well, a dock: the boat steers and alters its speed so that it can connect with the cleats on the pier deck. The Apollo Command and Lunar Modules docked in lunar orbit.

Docking


Berthing is when something at sea is snatched out of the open water and placed in a slip, or on a deck. Imagine a cargo ship being unloaded in a harbor. The harbor crane is berthing the cargo containers by stacking them in piles on the shore.The cargo containers are not under their own power - - the crane is doing all the work. The Dragon spacecraft is berthed with the ISS.

Berthing


This doesn't seem like it should be a big deal - - docking vs. berthing - - but in the history of space station operations, it's a best practice when the cargo can be berthed instead of docked.

Why? Because way back in 1997, a docking collision almost wiped out the Mir space station, and the six people on board. Progress ship M-34 had a stuck thruster and wound up ripping a gash in the starboard side of the Mir station, causing a sudden vacuum in the Spektr module and a series of lengthly repairs for the station. Although Russia still uses Progress ships to resupply the ISS, they use minimal thrusts to bring the spacecraft within the "danger zone" (the KOS or "Keep Out Sphere") of the station.

Progress SMASH!


Newer ships are designed around a berthing model. First, the ship will arrive from the underside, or R-bar axis of the station. Why? Let's take a look at the R-bar and see:


The R-bar is a line that runs from the bottom of the station through the center of the planet Earth. Any ship arriving from this direction will fall back towards Earth as the thrust is reduced. So, it's a safe vector if you want to get close to the space station without bumping into it.

Dragon will climb up the R-bar line until it crosses inside the KOS. Astronauts on board the ISS will reach out with the Canadarm and tuck the ship into a port on the bottom of the Harmony module. The connector for the ship and the station is called, aptly enough, a Common Berthing Mechanism, or CBM. Dragon's port hinges will click into place with the ISS mechanism, and -boom- mission accomplished!

So, if you get up early Friday morning to watch all this orbital ballet, you'll be able to yell at the TV with a sense of authority as you correct the woefully misinformed news reader. Hooray for you!

The Day the Space Age Didn't Start

September 20th, 1956 would have been the birthday of The Space Age, if not for a Presidential directive and a few pounds of sand.

Let's start a bit further back in history, because this story is mostly about, of all things, aerial surveillance and military intelligence. The 1940's ended with the Soviet Union exploding an atomic bomb, which took the United States and the rest of the world pretty much by surprise. The newly-elected President of 1953, Dwight Eisenhower, made it a top priority that the US government would no longer tolerate "surprises" in military intelligence. Ike demanded a clear picture of what the Soviets were up to: what their A-bomb inventory was, how many long-range bombers they had, that kind of thing. Congress, also appalled by the lack of strategic information, agreeed. Of course, this kind of information would require some sort of sophisticated aerial reconnaissance.

One of the most difficult problems in surveillance of another country by a military aircraft was that the act of overflight would, at least in the early 1950s, be considered an overt act of war. Sending USAF planes over the USSR would be the perfect trigger for the world's first nuclear exchange.

Eisenhower tried a radical diplomatic step to deflate the concerns about Soviet missile and bomber counting flights: he suggested that all nations adopt an “Open Skies" policy, where overflights by surveillance aircraft from other countries would be permitted over national boundaries. The Soviets rejected the proposal immediately, so Eisenhower was forced to come up with a sneakier way of taking pictures of Soviet airfields.

In 1955, Ike asked Dr. Edwin Land (yes, the Polaroid guy) to put together an intelligence subcommittee for the "President's Technological Capabilities Panel." This group would scope out any wacky, harebrained plots thought up by American scientists and engineers to reduce the provocative nature of the overflights. Land came up with an idea that the designs for a canceled Air Force spy plane, the CL-282, be transferred to the civilian Central Intelligence Agency.  Land convinced Eisenhower that the civilian Central Intelligence Agency, and not the United States Air Force, would provide pilots and operational support for any overflight missions, thus pre-empting the potentially catastrophic shoot-down of a military aircraft with a military pilot on-board. The CIA would then be in charge of reconnaissance operations with this new craft, renamed U-2, and civilian pilots would fly these spy planes on high-flying missions through Soviet airspace. With a fat, secret Congressional budget, the CIA built a handful of U-2 planes inside of a year.
Dr. Land's airplane: the U-2.


Only ten days after the U-2 plane became operational in mid-1956, President Eisenhower ordered the overflights to cease. Signal intercepts of Soviet radar stations indicated that the USSR was aware of the flights, and Eisenhower did not want to risk a shoot-down incident. Despite only flying a week and a half, the U-2 planes gave lots of tantalizing bits of information about airfields deep in the Soviet heartland. Ike needed another alternative to the U-2.

An obvious answer was a satellite, but Eisenhower still worried about the overflight by a spaceship (even one in orbit) as being an act of war. True, the flight would be unmanned, but the government division launching the rocket would be the US Army, led by an ex-Nazi rocket scientist with dirty hands.

Wernher von Braun, the Army's chief rocket designer, had quite a tainted past. He didn't begin his rocket career as a Nazi, but he certainly excelled in his craft during his tenure with them.

Amateur rocket societies flourished in Germany during the 1920’s and 1930’s, the largest of which was Verein für Raumschiffahrt (Society for Space Travel), or VfR. The rocket societies were not created for military research, but were social organizations for like-minded individuals who were interested in the exploration of space and the increase in scientific knowledge. Key German scientists and authors such as Hermann Oberth, Willy Ley, and Max Valier were early members --- so was von Braun.

Boys and their hobbies.
Wernher von Braun, at right, about 1932.



Wernher von Braun realized early on that rockets ran on funding almost as much as they did on fuel. Since rockets were not considered an effective military weapon, the Treaty of Versailles did not restrict the production of ballistic missiles. This omission proved endlessly fascinating to the German Army, who hired von Braun and his cohorts at VfR to build ever-increasing numbers of military rockets.

The German Army ordered the von Braun team  to create a rocket that would be able to carry a 100-kilogram explosive warhead a distance of 260 kilometers. Although too late to have an effect on the outcome of World War II, the von Braun A4 rocket (or V-2 as named by the Nazi hierarchy for “Reprisal Weapon-2”) delivered murderous damage to London and Antwerp at nearly four times the speed of sound. Rocket attacks from Germany killed more than 12,000 people and destroyed over 30,000 homes. Overlooked in the death toll are the fatalities of the 10,000 forced laborers and concentration camp inmates who worked on V-2 production at the Peenemünde and Nordhausen rocket facilities. Stationed in bombproof cave factories, many of the inmates died of pneumonia in the cold, damp working conditions.

Responsibility for these many deaths rested in no small part on the shoulders of von Braun and his staff. They realized their only hope in escaping war crimes charges would be in their ability to negotiate with the victors by trading technical information for their freedom.

The calculation was simple: if von Braun’s team surrendered to the Soviets, they'd face the wrath of a nation with 27 million war dead. The other choice was to bargain with the Americans, the fellow countrymen of rocket pioneer Robert Goddard. The von Braun team fled to the West, negotiating with their potential benefactors for a cave full of unused V-2 parts, milling machines, crates of technical documentation and engineering advice in exchange for political asylum. As the Germans had done back in the 1940's, the US Army put von Braun and his men to work, rebuilding V-2s and designing interregional ballastic missiles capable of carrying atomic bombs from border countries to downtown Moscow.

From the original V-2 came the Redstone and the Jupiter, suborbital missiles with more power than the original German model. In fact, it would take only a slight bit of tweaking (and funding) to get these new missiles to push a satellite into Earth orbit.

Once again, von Braun followed the research money to its source: in this case, the American taxpayers. Dr. von Braun’s public relations campaign had to move the popular culture away from the “mad scientist” stereotype imbued by earlier newspaper reporting of Robert Goddard’s Moon plans of the 1920s and replace those notions with the idea that space travel was not only practical, but imminent.
Dr. von B's PR campaign.

In 1952, Collier’s Magazine began publishing a series of articles written by von Braun and his colleagues, detailing the processes, potentials, and benefits of a manned space program. The magazine series, painstakingly illustrated with the cinematic realism of artist Chesley Bonestell, gave readers the impression that the government was already involved in building manned spacecraft, and that the only impediment to the conquest of space was additional government funding.

Dr. von Braun proved to be a master of Amercan public relations, eventually convincing Walt Disney to produce a series of TV features about "Man in Space" on Walt's "Disneyland"  series. Millions of Americans watched the  documentary-style programs, which reinforced the idea that America was on the threshold of conquering space.

"That's not my department, Walt,"
says Wernher von Braun.


President Eisenhower requested a print of the Disney program to screen at the Pentagon. However, he still was reluctant to rely on an ex-Nazi to experiment with world-girdling missiles over the Soviet Union. Ike proposed that the United States would orbit a scientific satellite during the International Geophysical Year of 1957. To avoid any semblance of military legacy from the former V-2 engineers, the President also designated the Navy's untested rocket, Vanguard, as the launch platform for the first satellite.

The President's Technological Capabilities Panel laid down the law to the Department of the Army: von Braun's team would in no way be allowed to launch anything into orbit. To make sure of this, the Army dispatched inspectors to Cape Canaveral to make sure there were no extra stages laying around to attach to the top of any Redstone or Jupiter missiles. The configuration of the 4th stage of the Army's Jupiter-C missile was loaded with sand, as extra ballast to prevent an "accidental" satellite.

The Jupiter-C, with its inert fourth stage
up on top.


So, on September 20th, 1956, the US Army launched a four-stage Jupiter missile with an inert top stage. The payload of 30 lbs of sand flew to an altitude of 680 miles at 16,000 mph, only to land in the South Atlantic, having never orbited the Earth. If the sand had been aluminum perchlorate rocket propellant, the Space Age would have begun that day.

The person aided most by this nearly orbital flight was the guy who designed rockets for the Soviet Union: Sergei Korolev. The Soviet Chief Designer made the case to the State Commission that their own plodding space program would need to be streamlined and funded better to put a small, simple satellite into orbit before the Americans. Korolev received permission from the State Commission to concentrate on launching a 184-lb satellite code-named "Object PS" and later renamed Sputnik. Sputnik would achieve orbit 13 months after the Jupiter-C launch.

The US Navy tried to launch their Vanguard about two months after Sputnik went into orbit. It didn't go too well.
Vanguard's peak altitude: 4 feet,
followed by a lot of exploding and burning.

After the Navy's very public failure, Eisenhower okayed von Braun's team to go ahead with an active fourth stage on their Jupiter missile, and a science satellite inside the nose of that top stage. Now renamed a Juno-I, the new launch vehicle hoisted the 30-lb payload into orbit on the last day of January, 1958. The Explorer 1 satellite was a success, sending back telemetry from high Earth orbit about a shell of radiation surrounding the planet. The shell, now called the Van Allen Belt, was named after a University of Iowa scientist who suggested putting a geiger counter inside the satellite.

America didn't get an actual spy satellite into orbit until the final weeks of the Eisenhower administration, but the resulting data told Ike (and select members of Congress) that there was no "bomber gap" with the Soviet Union. The Soviets didn't have much in the way of intercontinental military aircraft, so Congress didn't waste a lot of money building unnecessary anti-aircraft defense systems.

It's easy to be bothered by Eisenhower's intentional delay-of-game, but  two benefits came from America being second into orbit. First, the Soviet launch of Sputnik confirmed their tacit approval of the Open Skies policy, at least with spaceships in Earth orbit. Second, without the Soviets getting into orbit first, there would have been no ensuing Space Race, and consequently no Race to the Moon. I think we should count our blessings and move on.

Fiddle

Just realized it's been 10 years since I started playing the violin. I feel as though, after a whole decade,  I should be a better fiddle player, but I guess most people feel that way about their inadequacies playing their musical instruments.

After I turned 40 I decided I should branch out from my two long-time instruments of piano and guitar. So, I picked the violin because I knew almost nothing about how to play one, but I really liked the sound of a fiddle.

I found a music store near my house in Pennsylvania where they had violin tutors. The store owner paired me up with a Russian musician who taught at several prep schools on the Main Line. At my first lesson, the music teacher asked me if I owned a violin. I said no, I thought I'd wait and discuss it with people who knew about violins and would be able to recommend what the best kind of starter fiddle I should have.

The violin teacher closed the door to the practice room and handed me a business card. "You. Come to my house Saturday. I fix you up. Good price. Tell no one!" Then he handed me his violin and we began the first lesson.

As he suggested, I went to his house that Saturday and he led me to his basement workshop. He had dozens of violins in various states of repair hanging from the ceiling. He picked up a bright red violin. "This  - made by Chinese factory. Is firewood!" He dropped it on his workbench, and then sorted through a bunch of fiddles on a back wall. "This one - 300 years old. You can't afford it." My teacher brought out a black case and opened it up. "This one. Good sound, nice balance. Wood is really good. Made in the 1930s by Nazis. Play!" I picked up the Wehrmacht-era fiddle and ran the bow up the G scale. Really did sound nice. So now I owned a violin.

I played the violin for three years before I found out I preferred playing the fiddle. It's the same instrument, just played with a different attitude. I enjoyed fiddle playing with others, because playing ensemble keeps you honest about keeping up and playing the right notes at the right time.

When I moved into my house in Blackstone, I found out there were nearby fiddle classes in Rhode Island. I joined an intermediate group and went every week to clear my head and focus my fingers. It was fun, and I met a lot of similarly-inclined catgut scratchers who were very forgiving and quite entertaining.

Probably my favorite fiddle moment was being invited to play at a workshop with Jay Ungar and his wife Molly Mason. Jay is famous for his breathtaking song "Ashokan Farewell," which was used as the theme to Ken Burns' PBS show "The Civil War." It was one of my first fiddle tunes, and is still a favorite to play. You probably know the song, if not for the name, then for the tune. Here - allow yourself a few moments to become acquainted with this beautiful piece:




Jay and Molly were in Rhode Island, teaching a one-day seminar for anyone attending a music class in the state. Originally it was supposed to be for middle and high school students only, but when they came up short on the invite list, they added a few more slots for old-timers like me.

Here's a video of me, a few old codgers,  Jay and Molly, and a bunch of school kids sawing our way through one of Jay's other compositions, "The Lovers' Waltz." I think it all came out rather nice.




I'm still playing, but I need to practice more. Maybe after the Blue Cross gig finishes up, I'll take a few days and run through my repertoire.
