NASA's twin rovers launched separately in 2003 and landed three weeks apart in January 2004. They completed their three-month prime missions in April 2004 and went on to perform extended missions for years. Spirit and Opportunity made important discoveries about wet environments on ancient Mars that may have been favorable for supporting microbial life. Although Spirit ceased communicating with Earth in March 2010, the Opportunity rover continues its work on the Red Planet.
The participants include, among others:
-- Charles Elachi, director, JPL
-- Steve Squyres, professor of astronomy, Cornell University, Ithaca, N.Y., and principal investigator for the Mars Exploration Rover mission
-- John Callas, project manager, Mars Exploration Rover Project, JPL
-- Bill Nye, chief executive officer of the Planetary Society, Pasadena, Calif.
