The 2015 Report by the Science Definition Team and the WFIRST Study Office for the Wide-Field Infrared Survey Telescope-Astrophysics Focused Telescope Assets has been released to the pubic. It is the result of a of study into how the transfer of the Astrophysics Focused Telescope Assets (AFTA) to NASA can enable a truly compelling version of the Wide Field Infrared Survey Telescope (WFIRST), the top priority space mission identified in the 2010 National Academy of Sciences’ (NAS) decadal survey, New Worlds New Horizons (NWNH).

This report summarizes the science program of WFIRST-AFTA, presents a design reference mission, overviews the mission concept, describes recent progress in advancing the technical readiness of the key components, and shows how WFIRST-AFTA complements other planned ground-based and space-based telescopes to create an observing systems for the 2020s that will transform our understanding of the universe.
