Clay minerals, recently discovered to be widespread in Mars's Noachian terrains, indicate
long-duration interaction between water and rock over 3.7 billion years ago. Analysis of how …

Abstract The Sample Analysis at Mars (SAM) investigation of the Mars Science Laboratory
(MSL) addresses the chemical and isotopic composition of the atmosphere and volatiles …

As the search for Earth-like exoplanets gathers pace, in order to understand them, we need
comprehensive theories for how planetary atmospheres form and evolve. Written by two well …

Glaces et l'Activité (OMEGA) instrument on the European Space Agency's Mars Express …

Martian meteorites are the only direct samples from Mars, thus far. Currently, there are a total
of 262 individual samples originating from at least 11 ejection events. Geochemical …

The recent identification of large deposits of sulphates by remote sensing and in situ
observations has been considered evidence of the past presence of liquid water on Mars …

Geochemical models for Mars predict carbonate formation during aqueous alteration.
Carbonate-bearing rocks had not previously been detected on Mars' surface, but Mars …

Decades of speculation about a warmer, wetter Mars climate in the planet's first billion years
postulate a denser CO2-rich atmosphere than at present. Such an atmosphere should have …

Meteorite research is fundamental to our understanding of the origin and early history of the
Solar System. This book considers the mechanism and timing of core formation and basaltic …

If the large Late Hesperian outflow channels were eroded by extensive floods, as appears
likely, then large bodies of water must have once occupied the northern plains during that …
