TL;DR: Samples from the Rocknest aeolian deposit were heated to ~835°C under helium flow and evolved gases analyzed by Curiosity's Sample Analysis at Mars instrument suite, suggesting that oxygen is produced from thermal decomposition of an oxychloride compound.

TL;DR: In this paper, the authors report detection of background levels of atmospheric methane of mean value 0.69 ± 0.25 ppbv at the 95% confidence interval (CI).

TL;DR: Comparison between measurements in the modern atmosphere and those of martian meteorites such as ALH 84001 implies that the martian reservoirs of CO2 and H2O were largely established ~4 billion years ago, but that atmospheric loss or surface interaction may be still ongoing.

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.

TL;DR: In this article, the authors derived a spatially and temporally comprehensive set of in situ observations of CO2, CH4, and N2O obtained from 1992 to 1998 from the NASA ER-2 aircraft and balloon flights.
