Phoenix:
Phoenix was sent to Mars to search for evidence of past or present microbial life and to study geology and climate on the icy arctic plains of the Martian North Pole. The lander's robotic arm can dig up to half a meter (20 inches) into the martian soil and return it to the spacecraft for analysis. The spacecraft is equipped with a small oven
On May 25, 2008, the spacecraft landed the Vastitas Borealis region near the Red Planet's permanent north polar water-ice cap. The lander performed the first-ever wet-chemical soil analysis beyond Earth, sending back information that will help scientists determine if Mars ever supported life.
