NASA's Roman Space Telescope Finishes Construction Ahead of Schedule and Under Budget
NASA has completed construction of the Nancy Grace Roman Space Telescope, finishing ahead of schedule and under budget, with a September launch aboard SpaceX Falcon Heavy to the L2 point. The telescope features a 7.9-foot primary mirror, a 300-megapixel Wide Field Instrument, and a Roman Coronagraph for exoplanet imaging; it will survey the sky 1,000x faster, observe 200x more of the sky per image, and process data 2,000x faster than Hubble, potentially discovering billions of galaxies and tens of billions of stars while expanding infrared astronomy and exoplanet discovery.
