Spacecraft Exploration
Numerous channels eroded into the flanks of the crater's central mound could give access to the layers for study. Gale is the landing site of the Curiosity rover, delivered by the Mars Science Laboratory spacecraft, which was launched 26 November 2011 and landed on Mars at Gale Crater on the plains of Aeolis Palus on 6 August 2012. Gale was previously a candidate landing site for the 2003 Mars Exploration Rover mission, and has been one of four prospective sites for ESA's ExoMars.
In December 2012, scientists working on the Mars Science Laboratory mission announced that an extensive soil analysis of Martian soil performed by the Curiosity rover showed evidence of water molecules, sulphur and chlorine, as well as hints of organic compounds. However, terrestrial contamination, as the source of the organic compounds, could not be ruled out.
