Mars Phoenix Lander successfully landed on the Red Planet Mars on Sunday 25th May 2008, Phoenix will be the first spacecraft to study the Martian arctic plains and Phoenix landed farther north on Mars than any previous mission, at a site expected to have ice-rich permafrost beneath the surface, but within reach of the lander's robotic arms, which are used to search for signs of life, past or present. Of 11 previous attempts that various nations have made to land spacecraft on Mars, only five have succeeded. Nasa's Mars Exploration Mission before Phoenix :
