More and more the Atlas V appears to be “the vehicle of choice for manned missions.” Key quote:
NASA could have gone down this path last decade and possibly shaved years — and billions of dollars — off the development time of a capability to carry astronauts to the space station.

R.I.P: Roger Boisjoly, 73, has died.
Boisjoly was the engineer who in 1985 warned NASA about the danger of launching the shuttle in cold weather, that the solid rocket booster’s joints might not seal correctly under those conditions, thereby causing a catastrophic failure. Sadly, he was ignored, even ostracized, and on January 28, 1986, Challenger broke apart 74 seconds after launch, killing seven astronauts.

Getting close: Virgin Galactic hopes to begin the first powered flight tests of SpaceShipTwo this coming summer.
“Over the next few months we’re integrating parts and pieces of the hybrid rocket motor into the SpaceShipTwo airframe, completing ground testing of the rocket motor, and then [will] try and start powered flight over the summer,” [chief executive officer and president George] Whitesides told SPACE.com. Those rocket-powered flights, he said, will continue for some period of time. Whitesides said it looks possible “to get up to space altitude by the end of the year, if all goes well.”
The company is also building a second WhiteKnightTwo and SpaceShipTwo,
New dates, March 20 and May 15 respectively, have been set for the ISS launches of SpaceX’s Dragon capsule and the next manned Soyuz capsule.

The launch date for Dragon, however, is far more tentative.
The head of Russia’s space agency makes news again
The following stories are all the result of statements made by Vladimir Popovkin, the head of Roscosmos, the Russian Federal space agency, during a radio interview yesterday.
- Popovkin admits that U.S. radar had nothing to do with the Phobos-Grunt failure.
- Russia is “seriously considering” a repeat of its Mars-500 mission, this time on ISS.
- Russia might also land a man on the Moon by 2020.
This is the same guy that only a few weeks ago was throwing accusations at the U.S. for the failure of Phobos-Grunt.
What should we make of these statements? First, everything Popovkin says is aimed at fund-raising. Whatever his background, he is a political appointee whose job is to generate interest and funding for Russia’s space program. Everything he says in public must be weighed against this reality. That he first tried to shift the blame to the U.S. for Phobos-Grunt’s loss was an effort to absolve his program from any blame and thus reduce the possibility that the Russian government might cut his funding. Now that his agency has gotten approval of its insurance payment for the failure, however, he is free to say otherwise.
Second, these announcements give us a clear indication of where the Russia space effort is heading, and that effort looks both thoughtful and intelligent.

The Orion test capsule arrived in Alabama for tests, covered in fan signatures.
You think Americans aren’t interested in space travel? Get this: The Orion test capsule arrived in Alabama for tests, covered in fan signatures.
Orion and NASA’s space launch system might not get us there, but that doesn’t matter in this case. The public is expressing its desire for space travel quite clearly. All they need is someone to provide it to them at a reasonable cost.

The Great Moonbuggy Race
The Great Moonbuggy Race is an engineering competition that requires a team of six students to design a “proof-of-concept” wheeled rover that will race over a half mile of simulated lunar terrain. In April, two team members, one male and one female, will drive the completed vehicle in competition at the U.S. Space and Rocket Center in Huntsville, Alabama. This contest will present design challenges that are similar to those encountered by the original lunar rover team. This is the 16th year of competition for high school teams, but it will be the first year for Chicago’s public high school students.

The Russians now say the next manned flight to ISS will be delayed a month, until the end of April, due to defects found in the Soyuz capsule.
The Russians now say the next manned flight to ISS will be delayed a month, until the end of April, due to defects found in the Soyuz capsule.
The story suggests some confusion over what caused the cracks, either defects to the capsule itself or a mistake in the testing process.
A commission set up to probe the setback said violations of the testing procedure caused the damage to the reentry vehicle incident, earlier reports said. Either excessive pressure was applied by the personnel, or the shell of the reentry vehicle had defects or was improperly welded up.
Romney puts forth his space plans at a rally in Florida
In a campaign rally Friday in Florida, Mitt Romney put forth his perspective on the state of the American space program, and what he plans to do about it.
The speech is about 16 minutes long. It is worth listening to it in its entirety.
In it, Romney outlined the reasons he thinks a robust space program is important: defense, innovation, exploration, and the ability to respond to potential natural threats from space. Having done so, however, he then refused to outline any specific actions he would take to address these issues, saying instead that once in office he will bring together the right kinds of space experts who will then advice him on the right kind of plan to achieve all these important goals.
I appreciate his refusal to pander. At the same time, his vagueness does not make me enthusiastic. Moreover, he is only offering us the same thing we have seen numerous times before, another blue ribbon panel study outlining a plan. It would make me far happier if he already understood better the problems of the space program, and could articulate the actions he wishes to take, as Gingrich did.

“This re-entry capsule now cannot be used for manned spaceflight.”
“This re-entry capsule now cannot be used for manned spaceflight.”
This postponement of the next two Russian manned missions to ISS looks like a serious problem. For cracks to form in a finished capsule when tested under pressure suggests significant production failures that had gone unnoticed during assembly. In fact, this problem is far more serious than the launch failure that occurred last year. The Russians have to not only find a capsule they can trust to use on the next flight, they have to track down the errors that allowed a capsule to be built that is so obviously flawed it cracked when put in use.

The full Gingrich speech on space
As noted by one commenter, the full Gingrich speech on space is available here on C-SPAN.
I have now listened to the whole speech, and can say without hesitation that everything I wrote in my previous post was correct. Gingrich is knowledgeable about space, science, and history. He is basing his proposals on past successful models where the U.S. government did nothing but buy the product developed by private individuals or companies. These proposals actually continue as well as accelerate the Obama administration’s efforts. And he is not proposing a giant pork program.
His proposal to have a moon base by 2020 is unquestionably campaign talk that won’t happen. Nonetheless, this proposal is aimed at energizing the American aerospace industry by focusing the government’s goals, which will then need to be purchased by the government from private companies. He also made it very clear he wants to shrink the NASA bureaucracy, reducing its budget while devoting ten percent of that savings (equal to billions of dollars) for prizes. The example of a $10 billion tax-free prize for the first to get to Mars was only for illustration. As he said,
The model I want us to build is largely is the model of the ’20s and ’30s, when the government was actively encouraging development but the government wasn’t doing anything. The government was paying rewards, it was subsidizing the mail. … We had enormous breakthroughs in aviation in the ’20s and ’30s at very little cost to the government because lots of smart people [outside the government] did it.
I beg everyone to listen to this speech, in its entirety. It illustrates a thoughtful man who understands history. Gingrich might not be a perfect man, and he certainly is not the perfect candidate for President, but don’t tell me what you think of him if you refuse to listen to him. For two decades too many people have eagerly expressed opinions about him without really listening to what he has actually said or done. And what he says here is reasonable, intelligent, and certainly worthy of consideration.
