The Cores to Disks (c2d) Legacy program will be described, and first results of this program will be presented. The c2d program focuses on the formation of low-mass stars in nearby (within about 300 pc) clouds. It covers the range of star formation from the earliest, starless cores up to a stars about 10 million years old. In addition to targeting about 150 known compact cores, we will survey with IRAC and MIPS (3.6 to 70 micron) the entire areas of five of the nearest large molecular clouds for new candidate protostars and substellar objects as faint as 0.001 solar luminosities. We will also observe with IRAC and MIPS about 190 systems likely to be in the early stages of planetary system formation(ages up to about 10 Myr), probing the evolution of the circumstellar dust, the raw material for planetary cores. Spectroscopy with IRS of new objects found in the surveys and of a select group of known objects will add vital information on the changing chemical and physical conditions in the disks and envelopes. The resulting data products will include catalogs of thousands of previously unknown sources, multiwavelength maps of about 20 square degrees of molecular clouds, photometry of about 190 known young stars, spectra of at least 170 sources, ancillary data from ground-based telescopes, and new tools for analysis and modeling. Support for this work, part of the Spitzer Space Telescope Legacy Science Program, was provided by NASA through Contract Number 1224608 issued by the Jet Propulsion Laboratory, California Institute of Technology under NASA contract 1407.
