This comprehensive ebook provides a complete guide to the ongoing plans for NASA's Mars 2020 rover mission. The Mars 2020 mission would explore a site likely to have been habitable, seek signs of past life, fill a returnable cache with the most compelling samples, and demonstrate technology needed for the future human and robotic exploration of Mars. There is a reproduction of the "Mustard Report" - the report of the Mars 2020 Science Definition Team (SDT) headed by Jack Mustard.
