Water alteration of rocks and soils on mars at the spirit rover site in Gusev crater

Article Abstract:

The investigations of soils, rock coatings and rock interiors by the Spirit rover from sol 1 to sol 156, from its landing sites to the base of the Columbia hills are reported. The physical and chemical characteristics of the material that are analyzed provide evidence for limited but unequivocal interaction between water and the volcanic rocks of the Gusev rocks.

Solar eclipses of Phobos and Deimos observed from the surface of Mars

Article Abstract:

The small Martian satellites Phobos and Deimos orbit in synchronous rotation with inclinations of only 0.01 and 0.92 relative to the planets equatorial plane. The observations of six transits of Phobos and Deimos across the solar disk from cameras on Mars aboard the Mars Exploration Rovers, Spirit and Opportunity are presented.
