The Mars rovers, with the help of remote-sensing spacecraft, have sniffed out water and found the remains of one or more ancient environments where life could have survived. Indeed, early Mars is looking wetter and wetter. For an expanded version of this section, with references and links not found in the print edition, see www.sciencemag.org/sciext/btoy2004. 
Impact origin of sediments at the Opportunity landing site on Mars
A simple alternative explanation involving deposition from a ground-hugging turbulent flow of rock fragments, salts, sulphides, brines and ice produced by meteorite impact is presented, which can account for all of the features observed without invoking shallow seas, lakes or near-surface aquifers.

The Search for Sustainable Subsurface Habitats on Mars
On Earth, the deep subsurface biosphere of both the oceanic and the continental crust is well known for surviving harsh conditions and environments characterized by high temperatures, high pressures,Expand
Mars Primordial Crust: Unique Sites for Investigating Proto-biologic Properties
Early Mars appears to have been remarkably similar to early Earth, and samples of rock from the first few Ma or first 100 Ma may reveal “missing link” proto-biological forms that could shed light on the transition from abiotic organic chemistry to living cells. Expand
Geographers of Mars
This essay offers a new explanation for the power with which the notion of an inhabited Mars gripped noted scholars and everyday citizens on both sides of the Atlantic and suggests that turn‐of‐the‐century representations of Mars could be productively recontextualized alongside geographical works produced in the same period.

Electromagnetic Propagation of GPR Signals in Martian Subsurface Scenarios Including Material Losses and Scattering
The GPR performance in terms of resolution and maximum penetration depth is evaluated in the considered scenarios for different operating frequencies, thus providing a basic information for the design of systems for future subsurface sounding investigations on Mars. Expand

Diversity of halophilic archaea in the crystallizers of an Adriatic solar saltern.
Haloarchaeal diversity in the crystallizers of Adriatic Secovlje salterns was investigated using gene fragments encoding 16S rRNA and bacteriorhodopsin as molecular markers, indicating higher haloarchAeal diversity than previously reported in such hypersaline environments. Expand
