Rover Readies to Explore Life on Mars

Hosted by

Is there life on Mars? Scientists and science fiction writers have been puzzling over that for years. The answers may come one step closer when a new rover is launched from Cape Canaveral on Saturday. Curiosity is the biggest, most scientifically advanced Rover ever to land on another planet. It's five times bigger than predecessors Spirit and Opportunity and can operate ten times the scientific equipment. David Beaty is chief scientist of the Mars Directorate at NASA's Jet Propulsion Laboratory in Pasadena, California.
