Jet Propulsion Laboratory team members celebrate Mars Rover's safe landing in Pasadena, California

Scientists work inside the Spaceflight Operations Facility for NASA's Mars Science Laboratory Curiosity rover at Jet Propulsion Laboratory (JPL) in Pasadena, California on August 5, 2012. The Curiosity robot is equipped with a nuclear-powered lab capable of vaporizing rocks and ingesting soil, measuring habitability, and potentially paving the way for human exploration, and was designed to assess whether Mars ever had an environment able to support small life forms called microbes.
