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 bulk of the comet 81P/Wild 2 samples returned to Earth by the Stardust spacecraft appear to be weakly constructed mixtures of nanometer-scale grains, with occasional much larger ferromagnesian silicates, Fe-Ni sulfides,Fe-Ni metal, and accessory phases.

TL;DR: Impure reworked evaporitic sandstones, preserved on Meridiani Planum, Mars, are mixtures of roughly equal amounts of altered siliciclastic debris, of basaltic provenance (40−±10% by mass), and chemical constituents, dominated by evaporitic minerals (jarosite, Mg, Ca-sulfates, chlorides, Fe-, Na-solves), hematite and possibly secondary silica (60−± 10%).
