Our group seeks to understand the origin of the Solar System in the broader context of the local Galaxy through analyses of extraterrestrial materials (rocks and dust from asteroids and comets, circumstellar and interstellar grains, and samples of the solar wind).

We are a part of the Physics Department and the McDonnell Center for the Space Sciences at Washington University in St. Louis, and collaborate closely with the Department of Earth and Planetary Sciences.

MetSoc Meeting in Moscow

Last week, three members of our group were in Moscow presenting their work at the annual Meteoritical Society meeting, always my favorite scientific conference. I was happy to see Sasha Krot awarded the Leonard Medal — I was fortunate enough to get to work with Sasha at the University of Hawaii.

Columbia in St. Louis

I took my three-year-old soon to the St. Louis Science Center today to see the Columbia capsule from Apollo 11, two days prior to the 49th anniversary of Apollo 11’s launch. He asked about why it looked all “burned” and he could tell from my extreme enthusiasm how awesome it was.
