We summarize the progress to date of our Legacy Science Program entitled "TheFormation and Evolution of Planetary Systems" (FEPS) based on observationsobtained with the Spitzer Space Telescope during its first year of operation.In addition to results obtained from our ground-based preparatory program andour early validation program, we describe new results from a survey fornear-infrared excess emission from the youngest stars in our sample as well asa search for cold debris disks around sun-like stars. We discuss theimplications of our findings with respect to current understanding of theformation and evolution of our own solar system.
