PASADENA, Calif. – NASA’s Phoenix Mars Lander has ended operations after repeated attempts to contact the spacecraft were unsuccessful. A new image transmitted by NASA’s Mars Reconnaissance Orbiter shows signs of severe ice damage to the lander’s solar panels.
“The Phoenix spacecraft succeeded in its investigations and exceeded its planned lifetime,” said Fuk Li, manager of the Mars Exploration Program at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. “Although its work is finished, analysis of information from Phoenix’s science activities will continue for some time to come.”
During its mission, Phoenix confirmed and examined patches of the widespread deposits of underground water ice detected by Odyssey and identified a mineral called calcium carbonate that suggested occasional presence of thawed water. The lander also found soil chemistry with significant implications for life and observed falling snow. The mission’s biggest surprise was the discovery of perchlorate, an oxidizing chemical on Earth that is food for some microbes and potentially toxic for others.
