Comet 81P/Wild 2 under a microscope.

Donald E. Brownlee, +185 more
- 15 Dec 2006 - 
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.
Journal ArticleDOI

Mineralogy and petrology of comet 81P/wild 2 nucleus samples

Michael E. Zolensky, +75 more
- 15 Dec 2006 - 
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.
Journal ArticleDOI

Thermal alteration of hydrated minerals during hypervelocity capture to silica aerogel at the flyby speed of Stardust

TL;DR: In this article, the authors performed laboratory simulations of hypervelocity capture by using light-gas guns to impact into aerogels fine-grained powders of serpentine, cronstedtite, and Murchison CM2.
Journal ArticleDOI

TANPOPO: Astrobiology Exposure and Micrometeoroid Capture Experiments

TL;DR: In this paper, the authors proposed the analyses of interplanetary migration of microbes, organic compounds and meteoroids on the ISS-JEM using ultra low density aerogel.
Journal ArticleDOI

Evaluation of mineralogical alteration of micrometeoroid analog materials captured in aerogel

TL;DR: In this paper, the authors evaluated the intact survivability of high-speed projectiles in aerogel using impact experiments and found that they are mineralogically intact with the aerogels, at least in the interior of each particle, below 4 km/s.
