Meteorites, and the asteroid parent bodies that they come from are some of the fundamental building blocks of the solar system, including the terrestrial planets. They record the earliest history of the solar system, including the first geologic processes involving water and organic carbon. In this talk, Tim Glotch '99 will review what we've learned from carbonaceous chondrite meteorites as well as samples returned by two missions to near-Earth asteroids -- the Japanese space agency's (JAXA's) Hayabusa2 mission and NASA's OSIRIS-REx mission.
