NASA's Nancy Grace Roman Space Telescope, completed eight months early and under budget, is set to launch in September. It features a wide-field infrared imaging system capable of transmitting 1.4TB of data daily, enabling large-scale surveys of the early universe and nearby asteroids. The project repurposed surplus spy satellite hardware and represents a major advancement in space-based infrared astronomy.
Background
Space-based infrared telescopes like Spitzer have historically focused on high-resolution imaging of small areas, but astronomers have long sought a wide-field survey instrument for large-scale cosmic studies. The Roman Telescope originated from repurposed hardware from the National Reconnaissance Office.
