Two decades after its discovery, cosmic acceleration remains the most profound mystery in cosmology. WFIRST emerged as a top priority of Astro2010 in part because of its ability to address the mystery of cosmic acceleration in powerful ways. Mission design changes since Astro2010 have made WFIRST an even more powerful dark energy facility.
