(Newser) – The Phoenix Mars Lander grabbed a small sample of the fine soil of the planet's polar region yesterday. It was only a test "dig and dump"—using the spacecraft's 8-foot-long robotic arm—but paves the way for retrieving and analyzing samples of Martian soil later this week, reports the Arizona Republic.
