TL;DR: In this paper, the potential ionizing radiation damage to these important chemicals, tested their effectiveness following gamma radiation exposure doses up to the anticipated Europa Lander rating requirement of 300 krad(Si), were sealed in glass ampules under vacuum.

TL;DR: Results demonstrate that flash pyrolysis yields more diversity and greater abundances of TMAH thermochemolysis products than does the SAM-like ramp pyrolynsis method, and the presence of calcium perchlorate does not significantly impact the recovery rate of fatty acids with TMAh thermochemistryolysis under laboratory conditions, which is promising for the detection of fatty fatty acids via T MAH thermochemicalolysis with the SAM and MOMA instruments on Mars.

TL;DR: In this paper, a strong linear correlation between wt. % Cl detected by APXS and moles O2 detected by SAM during pyrolysis, indicating the presence of oxychlorine species in Gale Crater and, very likely, globally on Mars.

TL;DR: In this article , an evolved gas analysis (EGA) data from the Sample Analysis at Mars (SAM) instrument suite indicated Fe•rich smectite, carbonate, oxidized organics, Fe/Mg sulfate, and chloride in sedimentary rocks from the Glen Torridon (GT) region of Gale crater that displayed phyllosilicate spectral signatures from orbit.

TL;DR: In this article , the authors presented the first quantification of bulk organic carbon in Mars surface sedimentary rocks, enabled by a stepped combustion experiment performed by the Curiosity Rover in Gale crater, Mars.
