This month marks 10 years since twin Mars Exploration Rovers (MER), Spirit and Opportunity, landed on Mars.
Contact with Spirit was lost in 2010, but Opportunity still roams the Red Planet.
Tonight, join NASA's Jet Propulsion Laboratory (JPL), Pasadena, California for a live webcast starting at 8 PM to celebrate the decade old rover mission.
The mission command center is located at the JPL, but scientists from all over the United States are involved in the project.
Tonight's live webcast will feature Charles Elachi, the director of JPL, Steve Squyres, professor of astronomy at Cornell University in New York and the principal investigator for the Mars Exploration Rover mission, plus John Callas, project manager of the Mars Exploration Rover Project, and Bill Nye, chief executive officer of the Planetary Society located in Pasadena.
The event will be streamed live at http://ustream.tv/NASAJPL.
NASA says "Spirit and Opportunity made important discoveries about wet environments on ancient Mars that may have been favorable for supporting microbial life."
