Carbon stars, intermediate-mass asymptotic giant branch stars that have experienced deep dredge-up, represent a unique window on the Galactic history between 0.5 and 2 Gyr ago. Space Interferometry Mission will be used to find parallax distances to Galactic carbon stars. This will enable the isolation of carbon star streams analogous to moving groups and the subsequent identification of the main sequence turnoff stars that were congenital with the carbon stars. With the ages and initial abundances known, Galactic carbon stars will become useful tools for constraining stellar evolution like the Magellanic Cloud carbon stars are today. However, Galactic carbon stars have a higher initial metallicity and a better spread in age, making them even more useful, especially for application to extragalactic carbon star studies and integrated-light applications.
