The discovery of presolar silicates in IDPs and
meteorites has opened new opportunities. Isotopic analyses
of elements other than oxygen are expected to provide new
information on nucleosynthesis in the parent stars of the
grains. Identification of the mineralogy and chemical
composition of the grains can provide constraints on the
stellar atmospheres from which the grains condensed, but
only limited information exists. Finally, the abundance of
presolar grains in different types of meteorites is expected
to provide information on conditions in the early solar
