NASA Phoenix Lander Completes Longest Work ShiftJuly 22, 2008 -- Phoenix early Tuesday finished its longest work shift of the mission. The lander stayed awake for 33 hours, completing tasks that included rasping and scraping by the robotic arm, in addition to atmosphere observations in coordination with simultaneous observations by NASA's Mars Reconnaissance Orbiter. "Our rasping test yesterday gave us enough confidence that we're now planning for the next use of the rasp to be for acquiring a sample to be delivered to TEGA," said Phoenix project manager Barry Goldstein of NASA's Jet Propulsion Laboratory, Pasadena, Calif. TEGA is Phoenix's Thermal and Evolved-Gas Analyzer, an instrument that heats samples in small ovens and uses a mass spectrometer to study the vapors driven off by the heating. As preparation for that sample delivery in coming days, the Phoenix team developed plans to command the lander Tuesday evening to conduct 80 scrapings of the bottom of a trench informally named "Snow White." The scraping is designed to freshly expose frozen material and ready the surface for using the rasp. Click Here for videos associated with this press release.  |
THE MISSIONThe University of Arizona is honored to be the first public university to lead a mission to Mars. The Phoenix Mars Mission, scheduled to land May 25, 2008, is the first in NASA's "Scout Program." Scouts are designed to be highly innovative and relatively low-cost complements to major missions being planned as part of the agency's Mars Exploration Program. Learn More |
The Phoenix Mission is led by Principal Investigator Peter H. Smith of The University of Arizona, supported by a science team of CO-Is, with project management at NASA's Jet Propulsion Laboratory and development partnership with Lockheed Martin Space Systems. International contributions are provided by the Canadian Space Agency; the University of Neuchatel, Switzerland; the universities of Copenhagen and Aarhus Denmark; the Max Planck Institute, Germany; and the Finnish Meteorological Institute.
