The selected sites are: In November 2018, it was announced that Jezero crater was chosen as the planned landing site for Mars 2020 rover. A key mission requirement for this rover is that it must help prepare NASA for its Mars sample-return mission (MSR) campaign, which is needed before any crewed mission takes place. Such effort would require three additional vehicles: an orbiter, a
