Why high-speed rail makes no sense. Key quote:
High-speed rail would transform Amtrak’s small drain [on the government] into a much larger drain. Once built, high-speed rail systems would face a dilemma. To recoup initial capital costs — construction and train purchases — ticket prices would have to be set so high that few people would choose rail. But lower prices, even with favorable passenger loads, might not cover costs. Government would be stuck with huge subsidies. Even without recovering capital costs, high-speed rail systems would probably run in the red. Most mass-transit systems, despite high ridership, routinely have deficits.
China on the march! The next flight of their Shenzhou manned spacecraft could be a three week unmanned mission designed to test rendezvous and docking with their soon-to-launch Tiangong 1 space laboratory.
The delay yesterday of the launch of the European cargo ship to ISS might also delay the next Shuttle launch.
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.”

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.”
The images from Stardust’s flyby of Comet Tempel 1 are now available. I think the image below is the best, as it shows many details of the presently inactive comet surface. Scientists will need a bit of time now to compare these features with those imaged during the flyby of Deep Impact back in 2005.
It’s a tie after the first round of Jeopardy!’s computer vs human competition.

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.

More details on Liberty, the Ares/Ariane hybrid rocket proposed by ATK and Alliant to provide crew/cargo capabilities to ISS. Key quote:
[Liberty] would be able to lift 44,500 lb. of payload to the International Space Station, enough for any of the commercial crew capsules under development as potential space shuttle replacements.
Oy. A metal tool came apart last night and its scattered pieces fell on the shuttle Discovery. Fortunately, careful inspection of the orbiter has found no damage.
