Curiosity is a car-sized Mars rover exploring Gale crater and Mount Sharp on Mars as part of NASA's Mars Science Laboratory (MSL) mission.[2] Curiosity was launched from Cape Canaveral (CCAFS) on November 26, 2011, at 15:02:00 UTC and landed on Aeolis Palus inside Gale crater on Mars on August 6, 2012, 05:17:57 UTC.[3][4][5] 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.[6][7]
Mission 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.[8][9]
In December 2012, Curiosity's two-year mission was extended indefinitely,[10] and on August 5, 2017, NASA celebrated the fifth anniversary of the Curiosity rover landing.[11][12] On August 6, 2022, a detailed overview of accomplishments by the Curiosity rover for the last ten years was reported.[13] The rover is still operational, and as of 17 June 2024, Curiosity has been active on Mars for 4217 sols (4333 total days; 11 years, 316 days) since its landing (see current status).
