The discovery of nickel-, copper-, and zinc-bearing iron sulfides from comet 81P/Wild 2 (Wild
2) represents the strongest evidence, in the Stardust collection, of grains that formed in an …

Carbonaceous matter in Stardust samples returned from comet 81P/Wild 2 is observed to
contain a wide variety of organic functional chemistry. However, some of this chemical …

Transmission electron microscopy examination of 87 large fragments from 16 carrot‐shaped
and bulbous Stardust (SD) tracks was performed to study the range and diversity of …

We have characterized by transmission electron microscopy the mineralogy of samples
extracted from the walls of the Stardust track 80. More than 500 fragments were studied …

We report the presence of preserved primitive fine-grained material containing an enstatite
whisker with the crystallographic characteristics of a primary condensate in a sample of the …

A literature compilation of 1136 low‐Ca pyroxene compositions from chondrules from 12
primitive type 2–3 carbonaceous, ordinary and enstatite chondrite groups define unique …

The oxidation state of transition metal elements is an indicator of the environmental
conditions during formation and history of extraterrestrial materials. We studied the iron …

The fragile structure of chondritic-porous interplanetary dust particles (CP-IDPs) and their
minimal parent-body alteration have led researchers to believe these particles originate in …

The deceleration tracks in the Stardust aerogel display a wide range of morphologies, which
reveal a large diversity of incoming particles from comet 81P/Wild 2. If the large and dense …

Dust from comet 81P/Wild 2 was captured at high speed in silica aerogel collectors during
the Stardust mission. Studies of deceleration tracks in aerogel showed that a number of …
