SPIRIT UPDATE: NASA's Spirit Rover Survives Record Cold on Mars - sol 908-914, July 29, 2006:

Spirit remains healthy and continues to make progress on computer upgrades and scientific research, despite winter temperatures colder than any yet experienced during the rover's two and a half years on Mars. Models show that at the coldest part of the Martian night, around 5:00 a.m. Mars time, temperatures near the surface have dipped to approximately minus 97 degrees Celsius (minus 143 degrees Fahrenheit).

With the deepest part of the Martian winter just around the corner, Spirit is collecting about 284 watt-hours of electrical power each sol from the rover's solar array (a hundred watt-hours is the amount of electricity needed to light one 100-watt bulb for one hour). The shortest day, winter solstice in Mars' southern hemisphere, will arrive on Aug. 8, 2006. T
