WFIRST is a proposed infrared space telescope designed to study Dark Energy, our galaxy and to search for planets. WFIRST was the leading recommended large space-based project in the recent decadal survey, combining elements from the previous Joint Dark Energy Mission with a proposal to search for planets via gravitational lensing and perform infrared surveys. KIPAC scientists were very active in the development of instrumentation for a predecessor proposal JDEM, and are now looking forward to the development of WFIRST. While the schedule for WFIRST is currently uncertain, this ambitious mission may well be launched while the LSST 10 year survey is underway, and the complementarity of a ground-based survey with a space-based survey presents a compelling opportunity to enhance what we learn about Dark Energy.
