Mars: The Quest for Life

Phoenix - a robot geologist equipped to identify water on Mars - is on its way to find out. Carried on the space shuttle Delta II, Phoenix must travel 423 million miles to its final destination in the Martian Arctic. Will Phoenix survive the risky descent through the Martian atmosphere? The search for life is on the line. If successful, Phoenix will provide hard evidence of water on the planet and shift our understanding of life itself. (Discovery)
