Phoenix Mars Lander
A craft sent to Mars' frozen plains north of the planetâ€™s Arctic Circle to look at conditions that are conducive for life, including the presence of liquid water, organic molecules, energy sources, and chemicals that make up our life form. Phoenix will study the conditions by digging perhaps two or three feet into the frozen soil. Phoenix will also operate a weather station. Its readings will provide new information on the interplay between the planetâ€™s polar ice caps, its frozen ground, and its atmosphere.
