The Russians have confirmed that their scientists have successfully drilled into Lake Vostok in Antartica.

The Russians have confirmed that their scientists have successfully drilled into Lake Vostok in Antarctica.

Still no results, but this is not surprising, as these scientists will need time to analyze their data.

Update: More details from Science:

On Saturday, the drill had encountered water at about 3766 meters depth, but the team determined that it was a water lens sitting above the surface of the lake rather than the lake itself. The team collected water samples from the lens, and then kept drilling until reaching the lake surface itself. As expected, the pressurized water of the lake rose about 30 to 40 meters through the borehole and froze, plugging the borehole; the team will return next fall to retrieve the plug and examine it for signs of life.

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.

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.”

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,

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.

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.

Laser-guided bullets

Laser-guided bullets.

Invented by engineers at the US government’s Sandia National Laboratories, the self-guided bullet homes in on a laser spot trained on a target from up to 1.4 kilometres away from its firing point. If the target is a moving truck, say, and it moves after the bullet is fired, the laser illumination as seen by a laser sensor in the bullet’s nose instructs the bullet to finely twist tiny rudder-like fins on its rear end to keep it on target.

The Great Moonbuggy Race

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.

“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.
