Updated and bumped: Six days now, and no word.

Fact meets science fiction: For the last five days there has been no contact with the Russian scientists drilling down more than two miles to Lake Vostok in Antarctica.

The team from Russia’s Arctic and Antarctic Research Institute (AARI) have been drilling for weeks in an effort to reach isolated Lake Vostok, a vast, dark body of water hidden 13,000 ft. below the ice sheet’s surface. The lake hasn’t been exposed to air in more than 20 million years.

Priscu said there was no way to get in touch with the team — and the already cold weather is set to plunge, as Antarctica’s summer season ends and winter sets in. “Temps are dropping below -40 Celsius [-40 degrees Fahrenheit] and they have only a week or so left before they have to winterize the station,” he said. “I can only imagine what things must be like at Vostok Station this week.”

R.I.P: Roger Boisjoly, 73, has died.

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.

Virgin Galactic hopes to begin the first powered flight tests of SpaceShipTwo this coming summer.

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,

The head of Russia’s space agency makes news again

9:33 am

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.

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.

6:45 pm

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.
