Wee Rocky Droplets in Comet Dust Comet dust collected by the Stardust mission Small samples (10-40 microns) cut with micro- knife to make numerous samples for study

Wee Rocky Droplets in Comet Dust X-ray diffraction of small samples show the presence of the high- temperature minerals olivine and pyroxene Oxygen isotopic compositions are similar to carbonaceous chondrites, which formed in the asteroid belt, far from the region of comet formation Holes in sample were made by ion beam during analysis.

Wee Rocky Droplets in Comet Dust Assorted mechanisms may have transported high-temperature silicates to the outer Solar System where comets formed.
