An integrated view of the chemistry and mineralogy of Martian soils
Article Abstract:
Mineralogical and elemental compositions of the Martian soil are indicators of chemical and physical weathering processes. The data obtained from the Mars Exploration Rovers is used to show that bright dust deposits on opposite sides of the planet are part of global unit and not dominated by the composition of local rock.

A large dust/ice ratio in the nucleus of comet 9P/Tempel 1
Article Abstract:
The water vapor content and the cross-section of the dust created by the Deep Impact mission that shot a projectile into comet 9P/Tempel 1 is reported. The corresponding dust/ice mass ratio is probably larger than one, suggesting that comets are icy dirtballs rather than dirty snowballs as commonly believed.
