TL;DR: Chlorinated hydrocarbons identified in the Sheepbed mudstone by SAM are the reaction products of Martian chlorine and organic carbon derived from Martian sources or exogenous sources such as meteorites, comets, or interplanetary dust particles.

TL;DR: A single scoop of the Rocknest aeolian deposit was sieved and four separate sample portions, each with a mass of ~50mg, were delivered to individual cups inside the Sample Analysis at Mars (SAM) instrument by the Mars Science Laboratory rover's ample acquisition system.
Journal ArticleDOI

TL;DR: The Rocknest aeolian deposit is similar to aeOLian features analyzed by the Mars Exploration Rovers Spirit and Opportunity and implies locally sourced, globally similar basaltic materials or globally and regionally sourced basALTic components deposited locally at all three locations.

TL;DR: In situ measurements at Gale crater made over a 5-year period by the Tunable Laser Spectrometer on the Curiosity rover show large seasonal variation in the background and occurrences of higher temporary spikes that are consistent with small localized sources of methane released from martian surface or subsurface reservoirs.
Journal ArticleDOI
Evidence for indigenous nitrogen in sedimentary and aeolian deposits from the Curiosity rover investigations at Gale crater, Mars.

TL;DR: The detection of nitrate in both wind-drifted fines (RN) and in mudstone (JK, CB) is likely a result of N2 fixation to nitrate generated by thermal shock from impact or volcanic plume lightning on ancient Mars.
