The Nancy Grace Roman Space Telescope (shortened as Roman or the Roman Space Telescope, and formerly the Wide Field Infrared Survey Telescope or WFIRST) is a NASA infrared space telescope currently under development. The design of the Roman Space Telescope is based on one of the proposed designs for the Joint Dark Energy Mission (JDEM) between NASA and Department of Energy (DOE). Roman adds some extra capabilities to the original JDEM proposal, including a search for extra-solar planets using gravitational microlensing. Image Credit: NASA
