Curiosity (rover) conditions favorable for microbial life, including investigation of the role of water; and planetary habitability studies in preparation for human exploration. In December 2012, "Curiosity" two-year mission was extended indefinitely. On August 5, 2017, NASA celebrated the fifth anniversary of the "Curiosity" rover landing and related exploratory accomplishments on the planet Mars. The rover is still operational, and as of , "Curiosity" has been on Mars for sols ( total days) since landing on August 6, 2012. "(See current status.)" "Curiosity" design will serve as the basis for the planned Mars 2020 rover. As established by the Mars Exploration Program,
Crewed Mars rover the 2010s. The 1980s era Case for Mars design suggest a medium range rover with two compartments, one which could be depressurized and opened up to the Mars atmosphere, and a driving compartments which could remain pressurized during this time. The same study also suggested a bigger long duration rover with tracks and robotic arms, in addition to other types in that Mars surface human mission concept. Airlock design, especially for EVA is an area of study for pressurized rovers. Design ideas for crewed and/or pressurized rovers: Additional possible technologies: A 2004 analysis of a human Mars surface mission suggested
