Curiosity is a car-sized rover designed to explore the crater Gale on Mars as part of NASA’s Mars Science Laboratory mission (MSL).[3] Curiosity was launched from Cape Canaveral on November 26, 2011, at 15:02 UTC and landed on Aeolis Palus inside Gale on Mars on August 6, 2012, 05:17 UTC.[7][8][13] The Bradbury Landing site was less than 2.4 km (1.5 mi) from the center of the rover’s touchdown target after a 560 million km (350 million mi) journey.[9][14] 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.[15][16]
In December 2012, Curiosity’s two-year mission was extended indefinitely,[17] and on August 5, 2017, NASA celebrated the fifth anniversary of the Curiosity rover landing.[18][19] The rover is still operational, and as of May 11, 2020, Curiosity has been on Mars for 2760 sols (2835 total days) since landing on August 6, 2012. (See current status.)
Curiosity’s design serves as the basis for the planned Perseverance rover, which will carry different scientific instruments.
