If you aren't doing anything in 3 hours you can attend a meteorite lecture!  

Metamorphism of primitive solar system materials 

Chondritic meteorites represent the most primitive material in the solar system. These chondrites originate from asteroids that did not reach temperatures high enough to melt. Although they escaped melting, some of these primitive asteroids reached temperatures high enough to induce metamorphism - recrystallization of a rock in a solid state. Unlike Earth, where metamorphism is accompanied by pressure and heat, metamorphism on asteroids is driven only by temperature. This metamorphism results in textural and geochemical changes that provide insight into the thermal and physical evolution of small bodies during the solar system's earliest formation.
