NASA's most powerful space observatory since Hubble lifted off this morning. The Nancy Grace Roman Space Telescope launched at 7:26 AM EDT on August 30, 2026, riding a SpaceX Falcon Heavy rocket from Launch Complex 39A at Kennedy Space Center in Florida.
Roman carries a 2.4-meter primary mirror — the same size as Hubble's — but its infrared camera captures a field of view 200 times wider in a single image. NASA administrator Jared Isaacman noted that Roman's surveying capabilities are over 1,000 times faster than Hubble's: "What would take Hubble 2,000 years to process, Roman can do in a year."
The telescope's primary mission, expected to last five years, has two major goals. First, it will map billions of galaxies to study how the universe's expansion is accelerating, shedding light on the nature of dark energy and dark matter. Second, its onboard coronagraph will block starlight to directly image exoplanets and analyze their atmospheres — a technology demonstration for future Earth-like planet searches.
"We may serendipitously discover entirely new things we don't yet know to look for," said Julie McEnery, Roman's senior project scientist at NASA's Goddard Space Telescope Center.
The launch marks a milestone for NASA's astrophysics program, providing a survey telescope capable of charting 200 times more sky in a single exposure than any previous observatory.
