Oxidized and reduced sulfur observed by the Sample Analysis at Mars (SAM) instrument suite on the Curiosity rover within the Glen Torridon region at Gale crater, Mars

International audienceThe Curiosity rover investigated sulfur from the clay-bearing Glen Torridon region with the Sample Analysis at Mars instrument suite Multiple analyses (evolved gases, isotopes, comparative laboratory research) were used to determine whether sulfur was oxidized or reduced The samples mostly contained oxidized sulfur, but two had results consistent with reduced sulfur, which has implications for habitability Accepted Article This article has been accepted for publication and undergone full peer review but has not been through the copyediting, typesetting, pagination and proofreading process, which may lead to differences between this version and the Version of Record.
