Real robot drama is happening on Mars today. Spirit, racing for her life to find shelter before winter, injured and underpowered after four years of hard labor, may have made her most significant find yet. The broken foot she's dragged behind her for the past two years unexpectedly uncovered evidence of a once-wet Mars with conditions theoretically hospitable for primitive life.

NASA proposes using a Stirling cooler (essentially a Stirling engine in reverse) to keep a probe cool on the surface of Venus, which has had a tendency to melt or smash previous probes. The cooler would maintain a 25cm sphere within the probe at 200°C -- 100°C above the boiling point of water but sufficiently cool for a high-temperature microcontroller to operate. The waste heat radiators on the exterior of the sphere would reach the temperature of 500°C, 40°C above the the normal Venusian surface temperature.

"Somewhere on the planet are ten-year-olds who, someday, will be the first people to set foot on Mars" 300 scientists and space-experts contributed to what's billed as "a realistic vision of the first Human Mission to Mars" -- Race to Mars. Discovery Channel Canada used Hollywood special effects, but for added realism rather than ray-guns and aliens. On the website, you can argue about whether they got it right. www.racetomars.ca

Free at last, free at last, thank Mars almighty Opportunity is free at last. After a several week long struggle, the Mars Opportunity Rover is free from the sand trap many across the world had predicted would bring it to an end.

It looks like NASA may be altering the colors of the Mars Spirit rover photos.

We landed on Mars. The Mars Exploration Rover Spirit has captured its first color image of Mars. It is the highest resolution picture ever taken of another planet. Fascinating.

Mars, take II - Still no word from Beagle 2 (discussed here), unfortunately, as Mars maintains its tough reputation. However, the first of two rovers much larger than 1997's very successful Pathfinder is expected to hit the Martian surface with a giant bounce tonight at 8:35 p.m. PST. Check out the realistic simulation videos of how it will land and get to work, then watch Nasa TV (RealVideo) for live coverage.
