TL;DR: The Stardust spacecraft collected thousands of particles from comet 81P/Wild 2 and returned them to Earth for laboratory study, and preliminary examination shows that the nonvolatile portion of the comet is an unequilibrated assortment of materials that have both presolar and solar system origin.

TL;DR: In this paper, the authors show that the surface enrichment is the result of a minor amount of transport and deposition by aqueous processes on the surface of olivine-bearing basalts.

TL;DR: The Mars Exploration Rover Opportunity has investigated the landing site in Eagle crater and the nearby plains within Meridiani Planum, and the rocks are interpreted to be a mixture of chemical and siliciclastic sediments formed by episodic inundation by shallow surface water, followed by evaporation, exposure, and desiccation.

TL;DR: The alpha proton x-ray spectrometer (APXS) on board the rover of the Mars Pathfinder mission measured the chemical composition of six soils and five rocks at the Ares Vallis landing site, finding rocks are similar in composition to terrestrial andesites and close to the mean composition of Earth's crust.
