NASA's Roman Space Telescope to map the cosmos with a wide sky survey

NASA's Nancy Grace Roman Space Telescope has been fully assembled and will begin prelaunch work ahead of a fall 2026–May 2027 launch aboard SpaceX's Falcon Heavy from Kennedy Space Center. With an 8-foot mirror and a field of view about 100 times larger than Hubble's, Roman will survey the sky to study dark matter and dark energy while also hunting exoplanets through gravitational lensing in a Galactic Bulge Time-Domain Survey.
