Mars' Atmosphere from Curiosity The Sample Analysis at Mars (SAM) instrument on the Curiosity rover that landed on Mars in August last year is designed to study the chemical and isotopic composition of the martian atmosphere. Mahaffy et al. (p. 263) present volume-mixing ratios of Mars' five major atmospheric constituents (CO2, Ar, N2, O2, and CO) and isotope measurements of 40Ar/36Ar and C and O in CO2, based on data from one of SAM's instruments, obtained between 31 August and 21 November… 
Isotope Ratios of H, C, and O in CO2 and H2O of the Martian Atmosphere
TLDR
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.
Isotopic Composition of CO2 in the Atmosphere of Mars: Fractionation by Diffusive Separation Observed by the ExoMars Trace Gas Orbiter
Isotopic ratios in atmospheric CO2 are shaped by various processes throughout Mars' history, and can help understand what the atmosphere of early Mars was like to sustain liquid water on its surface.
Primordial argon isotope fractionation in the atmosphere of Mars measured by the SAM instrument on Curiosity and implications for atmospheric loss
TLDR
Results imply a substantial loss of atmosphere from Mars in the posthydrodynamic escape phase as well as excellent evidence that “Mars” meteorites are indeed of Martian origin.
Isotopes of nitrogen on Mars: Atmospheric measurements by Curiosity's mass spectrometer
TLDR
The meteorite mixing line is more consistent with the atmospheric composition measured by Viking than by MSL, and recent MSL/SAM measurements of the40Ar/14N ratio are incompatible with the Viking ratio.
Seasonal Variations in Atmospheric Composition as Measured in Gale Crater, Mars
The Sample Analysis at Mars (SAM) instrument onboard the Mars Science Laboratory Curiosity rover measures the chemical composition of major atmospheric species (CO2, N2, 40Ar, O2, and CO) through a

Stable Isotope Measurements of Martian Atmospheric CO2 at the Phoenix Landing Site
TLDR
Measurements of the isotopic composition of the martian atmospheric CO2, made in situ by the Mars Phoenix Lander, indicate that CO2 is heavily influenced by modern volcanic degassing and equilibration with liquid water, which suggests that low-temperature water-rock interactions have been dominant on Mars.
The composition of the atmosphere at the surface of Mars
We have confirmed the discovery of N2 and 40Ar by the Entry Science Team, and we have also detected Ne, Kr, Xe, and the primordial isotopes of Ar. The noble gases exhibit an abundance pattern similar
