On Sunday, NASA's Phoenix Mars Lander landed on Mars! Phoenix is on a three-month mission to excavate the soil on Mars using its 8-foot-long robotic arm to reach the ice believed to be buried inches to a foot deep. The lander will study whether the landing site could have supported primitive life. Among the things it will look for is whether the ice melted in Mar's history and whether the soil samples contain traces of organic compounds, one of the building blocks of life.
