Final reports of the Stardust Interstellar Preliminary Examination

Andrew J. Westphal, +69 more
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.
Journal ArticleDOI

Stardust Interstellar Preliminary Examination X: Impact speeds and directions of interstellar grains on the Stardust dust collector

Veerle Sterken, +68 more
TL;DR: In this paper, the trajectories of ISD in the solar system and the distribution of the impact speeds, directions, and flux of the ISD particles on the Stardust Interstellar Dust Collector during the two collection periods of the mission were predicted.
Journal ArticleDOI

Stardust Interstellar Preliminary Examination I: Identification of tracks in aerogel

Andrew J. Westphal, +86 more
TL;DR: In this paper, Westphal et al. reported the identification of 69 tracks in approximately 250 cm 2 of aerogelcollectors of the Stardust Interstellar Dust Collector using a distributed internet-based virtual microscope and search engine.
Journal ArticleDOI

Stardust Interstellar Preliminary Examination IV: Scanning transmission X-ray microscopy analyses of impact features in the Stardust Interstellar Dust Collector

Anna L. Butterworth, +69 more
TL;DR: In this paper, the authors report the quantitative characterization by synchrotron soft X-ray spectroscopy of 31 potential impact features in the aerogel capture medium of the Stardust Interstellar Dust Collector.
Journal ArticleDOI

Stardust Interstellar Preliminary Examination IX: High-speed interstellar dust analog capture in Stardust flight-spare aerogel

Frank Postberg, +79 more
TL;DR: In this paper, the results of laboratory hypervelocity impact experiments, during which cosmic dust analog particles (diameters of between 0.2 and 0.4 mu m), composed of olivine, orthopyroxene, or an organic polymer, were accelerated onto Stardust flight-spare low-density (approximately 0.01 g cm(-3)) silica aerogel.
