<br><br>Abstract<br><br>The Stardust mission successfully returned to Earth samples<br>of Comet Wild 2. Preliminary analysis of these samples<br>indicate that many of the minerals in the comet were formed<br>at much higher temperatures than expected in the comet
<br>formation region of our solar nebula. I will discuss what<br>these materials are telling us about the dynamical evolution<br>of our solar nebula and present a model for their origin that<br>is consistent with our astrophysical understanding of how
<br>planetary systems form.<br><br clear="all"><br>
