NASA's Roman Space Telescope, Hubble's Successor, Set for September Launch

NASA has completed the Nancy Grace Roman Space Telescope (NGRST), which is ahead of schedule and under budget. The observatory will launch as soon as September 2026 aboard a SpaceX rocket from Kennedy Space Center in Florida. Roman features a 300.8-megapixel infrared Wide Field Instrument and a Coronagraph, with 18 Teledyne H4RG-10 detectors sensitive to near-infrared and visible wavelengths. Its 8-foot mirror matches Hubble's size but captures 300 times more area per image. The telescope will map the universe, study dark energy and dark matter, survey the Milky Way, and discover exoplanets. It will send 11 terabytes of data daily. NASA administrator Jared Isaacman noted Roman will accomplish in one year what would take Hubble 2,000 years. The mission honors astronomer Nancy Grace Roman, known as the 'Mother of Hubble.' Deputy project manager Jackie Townsend said Roman will enable groundbreaking discoveries for decades. Systems engineer Mark Melton suggested Roman could win a Nobel Prize for unforeseen discoveries. The telescope will orbit one million miles from Earth.
