Summary
30 August 2026 is the target launch date for NASA’s Nancy Grace Roman Space Telescope on a SpaceX Falcon Heavy from Kennedy Space Center, with the observatory already finished, fuelled and ready ahead of its May 2027 commitment.
Roman’s 2.4-metre mirror matches Hubble’s, but its roughly 300-megapixel near-infrared camera captures an area about 100 times larger in one exposure, making it a fast survey telescope rather than a narrow deep-space observer like Webb.
A billion galaxies will be mapped to measure dark energy’s effects on cosmic expansion, while repeated monitoring of about 200 million stars toward the Milky Way’s centre is expected to uncover well over 1,000 exoplanets through microlensing.
A separate coronagraph technology demo will test deformable mirrors that suppress starlight to directly detect nearby planets, a step toward future missions aimed at imaging Earth-like worlds.
After launch, Roman will head to the Sun-Earth L2 point 1.5 million kilometres away and spend months in commissioning before its wide-field surveys begin, with its biggest scientific payoffs likely to take years.
