Morphological evidence for ancient channelized flows (fluvial and fluvial-like landforms)
exists on the surfaces of all of the inner planets and on some of the satellites of the Solar …

Laboratory measurements of physical properties of planetary ices generate information for
dynamical models of tectonically active icy bodies in the outer solar system. We review the …

Gale Crater contains a 5.2 km-high central mound of layered material that is largely
sedimentary in origin and has been considered as a potential landing site for both the MER …

The terms mélange and broken formation have been used in different ways in the literature.
The lack of agreement on their definition often leads to confusion and misinterpretations. An …

Perchlorate salts (mostly magnesium and sodium perchlorate) have been detected on Mars'
arctic soil by the Phoenix lander, furthermore chloride salts have been found on the …

New high-resolution spectral and morphologic imaging of deposits on walls and floor of Ius
Chasma extend previous geomorphic mapping, and permit a new interpretation of aqueous …

A model for the formation and distribution of sedimentary rocks on Mars is proposed. In this
model (ISEE-Mars), the rate-limiting step is supply of liquid water from seasonal melting of …

Written by two of the best US researchers in the field, this text investigates issues of
astrobiological relevance in the context of cold aqueous planetary geochemistry. At the core …

Earth's biological and environmental evolution are intertwined and inseparable. This
coevolution has become a fundamental concept in astrobiology and is key to the search for …

We review the reservoirs of methane clathrates that may exist in the different bodies of the
Solar System. Methane was formed in the interstellar medium prior to having been …
