Mission to Mercury

Mercury Messenger, a NASA probe, just performed a fly-by of Mercury at a height of 200 kilometers. It's the first spacecraft to visit Mercury since 1975.

Hot space bot uses stirling engine

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.

NASA's Phoenix probe launched Saturday from Cape Canaveral, destination Mars. Its mission is to investigate polar ice. This probe is unique for a couple of reasons: first, it will face a traditional parachute-and-retro-rockets landing, unlike previous endeavors. Second, it will be landing far north of any previous mission. Previous Mars missions have had mixed success, with only about half successfully making it to their destination. It is scheduled to land in May, 2008.

CIA Seeks Probe of Iraq-Al Qaeda Memo Leak The CIA will ask the Justice Department to investigate the leak of a 16-page classified Pentagon memo that listed and briefly described raw agency intelligence on any relationship between Saddam Hussein's Iraqi government and Osama bin Laden's al Qaeda terrorist network, according to congressional and administration sources...and if this probe is like so many others, that will be the end of this news item.

NEAR shoemaker lands and survives. The NEAR Shoemaker spacecraft touched down on a barren space rock called Eros on Monday, in history’s first attempt to land an object on an asteroid. Scientists said the probe still appeared to be sending signals back to Earth after making contact, hinting that the car-sized probe survived the descent. The speed at impact was between 1.5-1.8 m/s. This marks the first time that a US spacecraft was the first to land on another body of the solar system. And, if the server is back up, it's worth checking out the project's website.
