TL;DR: The Stardust Interstellar Dust Collector captured seven particles and returned to Earth for laboratory analysis have features consistent with an origin in the contemporary interstellar dust stream and more than 50 spacecraft debris particles were also identified as discussed by the authors.
Journal ArticleDOI
Alteration assemblages in the nakhlites: Variation with depth on Mars
TL;DR: In this paper, the secondary mineral assemblages in the nakhlite meteorites, Lafayette, Governador Valadares (GV), Nakhla, Yamato (Y)-000593 ⁄ Y-000749 have been studied using scanning electron microscopy, transmission electron microscope, and electron probe micro analysis.
Journal ArticleDOI
Widespread oxidized and hydrated amorphous silicates in CR chondrites matrices: Implications for alteration conditions and H2 degassing of asteroids
TL;DR: In this article, the mineralogy and Fe oxidation state of silicates in the matrices of 8 CR chondrites, from type 3 to type 1, were investigated using X-ray Absorption Near Edge Structure (XANES).
Journal ArticleDOI

TL;DR: Achlioptas et al. as mentioned in this paper showed that C2063, 1,154,1,0 (Track 154) and C2061 1,113,5 (Track 113) from the Stardust collection of Comet Wild2's coma have been studied by TEM and NanoSIMS.

TL;DR: The results from the preliminary examination of this collection, the Stardust Interstellar Preliminary Examination (ISPE), were presented in this article, where extraterrestrial materials were found in two tracks in aerogel whose trajectories and morphology are consistent with an origin in the interstellar dust stream, and in residues in four impacts in the aluminum foil collectors.
