Mars 2020 Rover

A key mission requirement is that it must help prepare NASA for its long-term Mars sample-return mission and crewed mission efforts. The rover will make measurements and technology demonstrations to help designers of a future human expedition understand any hazards posed by Martian dust, and will test technology to produce a small amount of pure oxygen (O2) from Martian atmospheric carbon dioxide (CO2). Improved precision landing technology that enhances the scientific value of robotic missions also will be critical for eventual human exploration on the surface. Based on input from the Science Definition Team, NASA defined the final objectives for the 2020 rover. Those become the basis for soliciting proposals to provide instruments for the rover’s science payload in the spring of 2014.
