Unable to reach a comparable geological contact farther south on Mars, NASA’s Curiosity rover has now approached an alternative site for investigating a geological boundary. Curiosity has been exploring on Mars since 2012.
- Curiosity is a car-sized robotic rover exploring Gale Crater on Mars as part of NASA’s Mars Science Laboratory mission (MSL).
- The rover’s goals include: investigation of the Martian climate and geology; assessment of whether the selected field site inside Gale Crater has ever offered environmental conditions favorable for microbial life, including investigation of the role of water; and planetary habitability studies in preparation for future human exploration.
- On June 24, 2014, Curiosity completed a Martian year—687 Earth days—after finding that Mars once had environmental conditions favorable for microbial life.
