Jul 26, 2024 · Yesterday, NASA announced that a rock spotted on Mars by its Perseverance rover contained some of the best signs yet that ancient microbial life may have once existed on the Red Planet.
Nov 19, 2023 · Theoretical model calculations predict that the high H2 and high Si concentrations of the hydrothermal fluids can be attributed to serpentinization of the troctolites and subsequent hydrothermal...
Apr 1, 2019 · We developed an algorithm to retrieve methane abundance (volume mixing ratio) on Mars from the PFS short wavelength channel (SWC) spectra.

Nov 28, 2019 · Impacts on early Mars can produce H2 and CH4 in the thermal plume. In a thick CO2 atmosphere, collision‐induced absorptions between CO2‐H2 and CO2‐CH4 can boost the greenhouse effect.
Oct 12, 2018 · The observations of CH 4 in Mars' atmosphere turn the theoretical musings of possible life on Mars into a necessary investigative component for interpreting observational data. The findings elevate the possibility of hydrothermal activity on Mars, which could furnish habitable environments by providing liquid water and redox energy to sustain life.
