NASA Mars 2020 landed mission development

In January of 2014, NASA received fifty-eight proposals from U.S. and international teams for science and exploration technology investigations, for consideration for inclusion as part of NASA’s next mobile landed mission to Mars. The results of the competitive procurement were released in late July of 2014: Seven payloads were selected for the investigations that would contribute to meeting the overall objectives of the mission. The extraordinary scientific and technology development interest in the Mars 2020 mission is a direct result of NASA’s sustained and coordinated plan for the exploration of Mars, and ultimately, its search for life elsewhere in the universe. The Mars 2020 Mission will preserve the heritage and directly build upon NASA’s Mars Science Laboratory Mission and Curiosity Rover to implement its mission. In this paper, early development history leading to its development announcement, as well as key development status and design features for its implementation, is summarized.
