The great wind scam

The great wind scam. Key quote:

“With demand for power at record levels because of the freezing weather, there have been days when the contribution of our forests of wind turbines has been precisely nothing,” wrote Richard Littlejohn in the Daily Mail Dec. 27. “It gets better,” Mr. Littlejohn continued. “As the temperature has plummeted, the turbines have had to be heated to prevent them from seizing up. Consequently, they have been consuming more electricity than they generate.”

Stardust images of comet locate crater from Deep Impact’s impact

More news from Stardust: scientists have now identified what they think is the crater produced by Deep Impact’s impact in 2005. Key quote:

The images revealed a 150-metre-wide crater at the Deep Impact collision point that was not present in 2005. The crater is a subtle feature in the images, but it appears consistently in multiple views from the spacecraft. “So I feel very confident that we did find the [impact] site,” said mission member Peter Schultz of Brown University in Providence, Rhode Island, at a press briefing on Tuesday. The crater’s features are “subdued” rather than sharply defined, like those of craters made in hard materials like rock. “The message is: This surface of the comet where we hit is very weak,” said Schultz. The crater also has a small mound in its middle, indicating that some of the material thrown up by the impact was drawn by the comet’s gravity back down into the crater, he said: “In a way, it partly buried itself.”

Astronauts simulate Mars landing

Astronauts on the Russian Mars500 simulated Mars mission simulated a Mars landing on Saturday. Key quote:

Three astronauts on the Mars500 simulated mission will make a simulated walk on the Mars “surface” Monday. After working 30 days on the simulated planet, the crew will then embark on a simulated 240-day return trip to Earth. Officials said the 520-day Mars500 mission is designed to test how humans cope with the physical and mental stresses of a long space flight.

Companies team up on new rocket

The competition to build rockets continues to heat up: A U.S. and European partnership is proposing its own new cargo rocket for NASA, using the Ares I first stage and the Ariane 5 second stage. Key quote:

Dubbed Liberty, the launcher looks similar to the Ares I rocket that was being developed for NASA’s Project Constellation, which was cancelled by the Obama Administration. For its first stage it employs the same advanced, five-segment version of the shuttle’s solid rocket booster. But in a move that significantly lowers development costs, the second stage of the rocket is based on the flight-proven core stage of Europe’s Ariane 5 rocket.

Falcon 9 signed to launch Google Lunar X prize competitor

One of the competitor’s for the Google Lunar X prize has signed a contract with SpaceX to use the Falcon 9 to get its spacecraft to the Moon. Key quote:

The Falcon 9 upper stage will sling Astrobotic on a four-day cruise to the Moon. Astrobotic will then orbit the moon to align for landing. The spacecraft will land softly, precisely and safely using technologies pioneered by Carnegie Mellon University for guiding autonomous cars. The rover will explore for three months, operate continuously during the lunar days, and hibernate through the lunar nights. The lander will sustain payload operations with generous power and communications.
