This image provided by NASA shows the full-circle panoramic view of the Phoenix Mars Lander taken during the first several weeks after NASA's Phoenix Mars Lander arrived on an arctic plain on Mars in late May. The Phoenix spacecraft 'tasted' Martian water for the first time, Wednesday July 30, 2008. The robot heated up soil in one of its instruments earlier this week. University of Arizona scientists say the chemical test confirms the presence of ice near the Martian north pole. [Agencies]
