NASA Curiosity Rover MSL (PBR)

Curiosity is a car-sized rover designed to explore the crater Gale on Mars as part of NASA’s Mars Science Laboratory mission (MSL). The rover’s goals include an investigation of the Martian climate and geology; assessment of whether the selected field site inside Gale has ever offered environmental conditions favorable for microbial life, including investigation of the role of water; and planetary habitability studies in preparation for human exploration. The rover is still operational as of this posting (Feb 2019).
