In 2025, NASA (hopefully with CSA as a partner) plans to launch WFIRST, the Wide Field Infrared Survey Telescope. WFIRST is a 2.4 meter telescope with more than a 100 times the field of view of the Hubble Space Telescope. WFIRST will fly with a wide field camera and a coronagraph. The wide field camera is poised to make significant contributions to our understanding of dark energy and to carry out a diverse program of astrophysics. The coronagraph should be able to obtain contrast ratios 1000x better than those previously achieved from space and characterize atmospheres of exoplanets.
