Assessment of Mars exploration rover landing site predictions

Article Abstract:

Analyses of the remote sensing data that was used to select the Mars Exploration Rover landing sites at Gusev crater and at Meridiani Planum is carried out. The results show that basic engineering parameters important for safely landing spacecraft such as elevation, atmospheric profile, bulk density, rock distribution and slope can be constrained using available and targeted remote sensing data.

Aeolian processes at the Mars Exploration Rover Meridian Planum-landing site

Article Abstract:

An in situ examination of a martian bright wind streak, which provides evidence consistent with a previously proposed formational model for such features, are presented. It is shown that the widely used criterion for distinguishing between aeolian saltation- and suspension-dominated grain behavior is different on Mars and that estimated wind friction speeds between 2 and 3 ms(super -1).

Indication of drier periods on mars from the chemistry and mineralogy of atmospheric dust

Article Abstract:

The mars exploration rovers have permanent magnets to collect atmospheric dust for investigation by instruments on the rovers. The dust on the magnet contains magnetite and olivine, this indicates a basaltic origin of the dust and shows that magnetite, not maghemite is the mineral mainly responsible for the magnetic properties of the dust.
