This Catalog summarizes the samples examined in the course of the Preliminary Examination (PE) Team (PET) of the Stardust Mission to comet Wild 2, and the results of the analyses of those samples. The Catalog is intended as a preliminary guide to the samples that are available for allocation to the larger planetary science community. Thus there is very detailed information about the samples that have been removed from the sample tray. In addition, there is enough detail about the samples that remain in the aerogel in the tray to permit investigators to request 'fresher' samples as well.
