Mars Polar Lander / Deep Space 2

Mars Polar Lander was an ambitious mission to set a spacecraft down on the frigid terrain near the edge of Mars' south polar cap, and dig for water ice with a robotic arm. Piggybacking on the lander were two small probes called Deep Space 2, designed to impact the Martian surface to test new technologies. Mars Polar Lander and Deep Space 2 were lost on arrival Dec. 3, 1999.
