Mars 2020 (rover)
The Mars 2020 rover mission is a Mars rover mission by NASA's Mars Exploration Program with a planned launch in 2020.〔 It is intended to investigate an astrobiologically relevant ancient environment on Mars, investigate its surface geological processes and history, including the assessment of its past habitability, the possibility of extant life on Mars, and potential for preservation of biosignatures within accessible geological materials. The proposed landing site for the mission is Jezero crater located in the Syrtis Major quadrangle at coordinates .
''Mars 2020'' was announced by NASA on 4 December 2012 at the fall meeting of the American Geophysical Union in San Francisco.〔 The rover's design will be derived from the ''Curiosity'' rover, and will carry a different scientific payload. Nearly 60 proposals for rover instrumentation were evaluated and, on 31 July 2014, NASA announced the payload for the rover.
== Mission ==
The rover is planned to be launched in 2020.〔 The Jet Propulsion Laboratory will manage the mission. The specific payload and science instruments for the mission will be debated and selected by April 2014 through an open competition after the scientific objectives for the mission have been formulated. The mission will also be contingent on receiving adequate funding.〔 Precise mission details will be determined by the mission's science definition team.〔
