Two decades after its discovery, cosmic acceleration remains the mostprofound mystery in cosmology and arguably in all of physics. Either theUniverse is dominated by a form of dark energy with exotic physical propertiesnot predicted by standard model physics, or General Relativity is not anadequate description of gravity over cosmic distances. WFIRST emerged as a toppriority of Astro2010 in part because of its ability to address the mystery ofcosmic acceleration through both high precision measurements of the cosmicexpansion history and the growth of cosmic structures with multiple andredundant probes. We illustrate in this white paper how mission design changessince Astro2010 have made WFIRST an even more powerful dark energy facility andhave improved the ability of WFIRST to respond to changes in the experimentallandscape. WFIRST is the space-based probe of DE the community needs in themid-2020s.
