abstract = {With the discovery of bona fide extraterrestrial materials
in the Stardust Interstellar Dust Collector, NASA now has a
fundamentally new returned sample collection, after the
Apollo, Antarctic meteorite, Cosmic Dust, Genesis, Stardust
Cometary, Hayabusa, and Exposed Space Hardware samples.
Here, and in companion papers in this volume, we present the
results from the Preliminary Examination of this collection,
the Stardust Interstellar Preliminary Examination (ISPE). We
found extraterrestrial materials 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. While the
preponderance of evidence, described in detail in companion
papers in this volume, points toward an interstellar origin
for some of these particles, alternative origins have not
yet been eliminated, and definitive tests through isotopic
analyses were not allowed under the terms of the ISPE. In
this summary, we answer the central questions of the ISPE:
How many tracks in the collector are consistent in their
morphology and trajectory with interstellar particles? How
many of these potential tracks are consistent with real
interstellar particles, based on chemical analysis?
Conversely, what fraction of candidates are consistent with
either a secondary or interplanetary origin? What is the
mass distribution of these particles, and what is their
state? Are they particulate or diffuse? Is there any
crystalline material? How many detectable impact craters
(>100 nm) are there in the foils, and what is their size
distribution? How many of these craters have analyzable
residue that is consistent with extraterrestrial material?
And finally, can craters from secondaries be recognized
through crater morphology (e.g., ellipticity)?},
