"NASA SMD intends to release an Announcement of Opportunity (AO) entitled Mars 2020 Investigations to solicit proposals for investigations for a space flight mission to Mars, to be launched in July/August 2020. The target date for release of the AO is no earlier than (NET) September 16, 2013. The SMD budget for Phases A-D is expected to be approximately $100 million in real year (RY) dollars. Investigations comprised of individual instruments or multiple instruments (suites) may respond to the overall Mars 2020 science objectives to explore and quantitatively assess Mars as a potential habitat for life, to search for signs of past life, and to collect carefully selected samples for possible future return to Earth. Proposals that address objectives for advancing knowledge or technologies for future robotic and/or human exploration of Mars will also be solicited."
