Kinetic model of carbonate dissolution in Martian meteorite ALH84001 [PDF]
, 2003 The magnetites and sulfides located in the rims of carbonate globules in the Martian meteorite ALH84001 have been claimed as evidence of past life on Mars.

International Astronomical Union Colloquium, 1971 The Martian satellites are some of the most interesting and accessible objects in the solar system, and therefore worth studying or even visiting. As small bodies, on the order of kilometers in diameter (see table I), they may have experienced no internal heating or volcanism, and could therefore be original condensations in the solar system.

Meteoritics &Planetary Science, Volume 60, Issue 3, Page 544-569, March 2025.Abstract Refractory inclusions (RIs) in chondrites are widely used as tracers of early solar system formation conditions. In the context of sample‐return missions, a non‐destructive and non‐invasive analytical tool that can rapidly detect and characterize RIs in space samples during their early phase of study is highly needed.

Chalcophile Element Constraints on the Sulfur Content of the Martian Mantle [PDF]
The sulfur content of the Martian mantle is critical to understanding volcanic volatiles supplied to the surface of Mars and possibly climate. In the absence of Martian mantle rocks, sulfur content of the mantle has been inferred from S contents of ...

The depth of the convective boundary layer and implications for a Walker-like circulation on Mars [PDF]
, 2011 Radio science observations indicate that the depth of the martian convective boundary layer varies strongly with surface height, although the surface temperature does not.

Scattering matrices and expansion coefficients of Martian analogue palagonite particles
, 2008 We present measurements of ratios of elements of the scattering matrix of Martian analogue palagonite particles for scattering angles ranging from 3 to 174 degrees and a wavelength of 632.8 nm.

Meteoritics &Planetary Science, EarlyView.Abstract Dating rocks with a 2σ precision of 200 Ma is required to understand the history of Martian habitability and volcanic activity since ~4000 Ma. In situ K‐Ar dating using a spot‐by‐spot laser ablation technique has been developed for isochron dating on Mars.

Hypotheses for near-surface exchange of methane on Mars [PDF]
, 2016 The Curiosity rover recently detected a background of 0.7 ppb and spikes of 7 ppb of methane on Mars. This in situ measurement reorients our understanding of the Martian environment and its potential for life, as the current theories do not entail any ...
