...Hugues Leroux; Damien Jacob; Julien Stodolna; Keiko Nakamura-Messenger; Michael E. Zolensky Abstract The Stardust spacecraft successfully returned dust from comet 81P/Wild 2 to Earth in January 2006. Preliminary examination of the samples showed abundant crystalline silicates comparable to those...

... that are considerably out of equilibrium with each other. This is consistent with the idea that cometary materials should have largely escaped extensive parent body processing. The study of samples recently returned from Comet 81P/Wild 2 by the Stardust spacecraft has immensely improved our understanding of cometary...

... of the dust from comet Wild 2 are very similar to those of carbonaceous chondrites, a class of meteorites allegedly derived from primitive, dark asteroids. Comets no longer represent extremely primitive samples of the early Solar System that are radically different from dark asteroids. We enter a new era...

..., and because of the strong correlation of O 2 with H 2 O, it has been suggested that the O 2 is preserved from the interstellar medium ( Bieler et al. 2015 ). Organic materials in some of the dust particles collected by the Stardust spacecraft from comet 81P/Wild 2 are poor in aromatic carbon...
