March 28, 2006

Twin robotic explorers Spirit and Opportunity have added a great deal to our understanding of Mars. Among other things, they have found substantial evidence that at one time, there was water on the surface of the planet. Today on Focus, Cornell University astronomer Steven Squyres talks us through what we know so far and the big question... was there ever life on the Red Planet?
