Phoenix Obituary


The Mars lander Phoenix has apparently stopped functioning after five months of data collection. It was the northernmost landing area of any spacecraft sent to Mars. "Apparently", because the mission engineers will continue to monitor for signals sent by Phoenix, but it is likely that the recent dust storms on Mars have not allowed enough sunlight to reach its solar panels to allow the equipment to continue operation. The lander was originally intended to function for three months. The last signal was received November 2, 2008.

It was a very sophisticated remote laboratory, and among its accomplishments were confirming the presence of water-ice below the surface of Mars (it had an arm for digging into the soil), taking over 25 000 photos using the first "atomic force microscope" ever used outside the Earth, doingn chemical analysis of the martian soil, and studying martian weather, including the first ever observation of snow falling from the clouds on Mars! (See this blog September 29). All things Phoenix can be found at http://www.nasa.gov/phoenix .
