As pristine condensates from a large number of stars, pre-solar grains provide unique information on the sources, types, compositions and processing histories of dust in the Galaxy. However, their promise remains largely unfulfilled. Here we discuss some of the astrophysical problems for which pre-solar grains might provide important insights and constraints in coming years.
