Nancy Grace Roman Space Telescope Key Ring

The next great NASA space telescope that will follow Hubble and the James Web Space Telescope or JWST will be launched in the mid 2020’s. This is the Nancy Grace Roman Space Telescope or NGRST, formerly called the Wide-Field Infrared Survey Telescope or WFIRST. The Roman telescope will have a primary mirror the same size as Hubble’s but a field of view that is 100 times greater. It is expected to find about 2,600 new exoplanets and will measure light from a billion galaxies over its mission lifetime of 5 years that could be extended another 5 years. It’s namesake, Dr. Nancy Grace Roman, is an astronomer known as the “Mother of Hubble for her work in getting the Hubble Space Telescope approved by Congress.
