Hundreds of ancient lake basins detected on Mars via orbital remote sensing represent rare
oases of hydrosphere–atmosphere–lithosphere interactions with great astrobiological …

This study surveys the evolution of martian impact crater paleolakes through time by
establishing their age, comparing their locations, and describing the formation of lacustrine …

We review the radiometric ages of the 16 currently known Martian meteorites, classified as
11 shergottites (8 basaltic and 3 lherzolitic), 3 nakhlites (clinopyroxenites), Chassigny (a …

It has long been suggested that hydrothermal systems might have provided habitats for the
origin and evolution of early life on Earth, and possibly other planets such as Mars. In this …

Paleolakes in impact craters on Mars are characterized at global scale using the Viking
Orbiter data. We identified 179 paleolakes in impact structures formed by the influx of water …

A radiative transfer model is used to quantitatively investigate aspects of the martian
ultraviolet radiation environment, past and present. Biological action spectra for DNA …

We report on numerical modeling results of postimpact cooling of craters with diameters of
30, 100, and 180 km in an early Martian environment, with and without the presence of …

We conducted a petrologic study of apatite within 12 Martian meteorites, including 11
shergottites and one basaltic regolith breccia. These data were combined with previously …

A fundamental long‐standing question regarding Mars history is whether the flat and low‐
lying northern plains ever hosted an ocean. The best opportunity to solve this problem is …

Impacts of asteroids and comets posed a major hazard to the continuous existence of early
life on Mars, as on Earth. The chief danger was presented by globally distributed ejecta …
