Mesmerized by Mars

This is just a little interview with Dave Beaty, the chief scientist for Mars exploration at the Jet Propulsion Laboratory in Pasadena. He explains some of the new programs and what motivates him to focus on Mars. One interesting question was whether he believed that life could exist without water. He acknowledges that "alternative lifestyle" may be possible. However, due to the similar raw materials present on both planets, he more interested in if organisms on Mars would be similar to organisms on earth. I find it interesting that we expect to find something that would be familiar , when actually we may find something completely "alien".
