Rotationally-Resolved Infrared Spectroscopy of Vesta: It's More Interesting Than You'd Think from the Title

Wednesday, May 4, 2005
Rivkin (MIT Earth, Atmospheric and Planetary Sciences)

Although it is one of the most well-studied objects in the asteroid belt and scientists have the benefit of samples from its surface, Vesta still holds surprises for those who observe it. We observed Vesta over a full rotation in 2004, and archival data from 2003, 2001, and earlier allow us to synthesize a global view of this object. I will present results from these 2-4 micron observations as well as implications for space weathering, impactor contamination, and solar wind implantation on Vesta and other objects.
