'Curiosity' is a car-sized Mars rover designed to explore the Gale crater on Mars as part of National Aeronautics and Space Administration (NASA) Mars Science Laboratory (MSL) mission. 'Curiosity' was launched from Cape Canaveral (CCAFS) on 26 November 2011, at 15:02:00 Coordinated Universal Time (UTC) and landed on Aeolis Palus inside Gale crater on Mars on 6 August 2012, 05:17:57 UTC. 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.

Gale is a crater, and probable dry lake, at 5.4°S 137.8°E in the northwestern part of the Aeolis quadrangle on Mars. It is 154 km (96 mi) in diameter and estimated to be about 3.5-3.8 billion years old. The crater was named after Walter Frederick Gale, an amateur astronomer from Sydney, Australia, who observed Mars in the late 19th century.

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.
