Martian Surface and Atmosphere Workshop

open access: yesEos, Transactions American Geophysical Union, 1992
The NASA‐sponsored Martian Surface and Atmosphere Through Time Study Project convened its first major meeting at the University of Colorado in Boulder, September 23–25, 1991. The workshop, co‐sponsored by the Lunar and Planetary Institute (LPI) and the Laboratory for Atmospheric and Space Physics at the University of Colorado, brought together an ...

Hypogravity simulation using the Variable Gravity Suspension System: A technical report

open access: yesExperimental Physiology, EarlyView.
Abstract Human movement has evolved within Earth's gravitational environment (1 g; −9.81 m s−2). Future human exploration of terrestrial bodies, including the Moon (0.17 g; −1.62 m s−2) and Mars (0.38 g; −3.71 m s−2), will require astronauts to live and work within reduced gravitational environments (hypogravity).

Catalytic/Protective Properties of Martian Minerals and Implications for Possible Origin of Life on Mars

open access: yesLife, 2018
Minerals might have played critical roles for the origin and evolution of possible life forms on Mars. The study of the interactions between the “building blocks of life„ and minerals relevant to Mars mineralogy under conditions mimicking the

Evolution of Water Reservoirs on Mars: Constraints from Hydrogen Isotopes in Martian Meteorites

open access: yes, 2014
Martian surface morphology implies that Mars was once warm enough to maintain persistent liquid water on its surface. While the high D/H ratios (~6 times the Earth's ocean water) of the current martian atmosphere suggest that significant water has been ...

Hypotheses for near-surface exchange of methane on Mars [PDF]

open access: yes, 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 ...

Seasonal Ice Cover Could Allow Liquid Lakes to Persist in a Cold Mars Paleoclimate

open access: yesAGU Advances, Volume 7, Issue 1, February 2026.
Abstract Geomorphic and stratigraphic studies of Mars prove that extensive liquid water flowed and pooled on the surface early in Mars' history. Martian paleoclimate models, however, have difficulty simulating climate conditions warm enough to maintain liquid water on early Mars.
