NASA Administrator Jared Isaacman walks in front of the Nancy Grace Roman Space Telescope after it was unveiled to the public at NASA's Goddard Space Flight Center in Greenbelt, Maryland on April 21, 2026. Named after NASA's first chief astronomer, the Nancy Grace Roman Space Telescope will have a field of view at least 100 times larger than Hubble's, potentially measuring light from a billion galaxies in its lifetime. It is expected to be launched in late 2026 or early 2027. (Photo by SAUL LOEB / AFP via Getty Images)
