05.25.08 — A NASA spacecraft today sent pictures showing itself in good condition after making the first successful landing in a polar region of Mars.
Radio signals received at 4:53:44 p.m. Pacific Time (7:53:44 p.m. Eastern Time) confirmed that the Phoenix Mars Lander had survived its difficult final descent and touchdown 15 minutes earlier. In the intervening time, those signals crossed the distance from Mars to Earth at the speed of light. The confirmation ignited cheers by mission team members at NASA’s Jet Propulsion Laboratory, Pasadena, Calif.; Lockheed Martin Space Systems, Denver; and the University of Arizona.
Phoenix carries science instruments to assess whether ice just below the surface ever thaws and whether some chemical ingredients of life are preserved in the icy soil. These are key questions in evaluating whether the environment has ever been favorable for microbial life. Phoenix will also study other aspects of the soil and atmosphere with instrument capabilities never before used on Mars. Canada supplied the lander’s weather station.
