Mars Science Laboratory Observations of Chloride Salts in Gale Crater, Mars

Gale crater: the Mars Science Laboratory/ Curiosity Rover Landing Site

Gale crater formed from an impact on Mars *3.6 billion years ago. It hosts a central mound nearly 100 km wide and *5 km high, consisting of layered rocks with a variety of textures and spectral properties. The oldest exposed layers contain variably hydrated sulphates and smectite clay minerals, implying an aqueous origin, whereas the younger layers higher on themound are covered by amantle of d...

Mars atmosphere. Mars methane detection and variability at Gale crater.

Reports of plumes or patches of methane in the martian atmosphere that vary over monthly time scales have defied explanation to date. From in situ measurements made over a 20-month period by the tunable laser spectrometer of the Sample Analysis at Mars instrument suite on Curiosity at Gale crater, we report detection of background levels of atmospheric methane of mean value 0.69 ± 0.25 parts pe...
