NASA announced on 2 September that the Nancy Grace Roman Space Telescope had successfully launched on 30 August from Kennedy Space Center and was on its trajectory to the Sun-Earth L2 point, beginning its five-year mission to map the sky and study dark energy, dark matter and exoplanets. The launch used a SpaceX Falcon Heavy rocket, delivering the 2. 4-meter infrared observatory with a field of view about 100 times larger than Hubble’s. NASA said the telescope’s wide-field camera will survey billions of galaxies and detect thousands of distant exoplanets.

Japan’s space agency JAXA will contribute scientific instruments and operate a ground-station in Nagano to support the mission. The $4-4. 3 billion project follows years of development and aims to improve measurements of the universe’s expansion.

摘要

All four claims about the Nancy Grace Roman Space Telescope were partially confirmed. The telescope's $4 billion budget and planned launch on August 30, 2026, aboard a SpaceX Falcon Heavy were partially confirmed. The claim that the telescope will have a field of view 100 times larger than Hubble was also partially confirmed. Its goals to map dark matter, measure cosmic expansion, and discover thousands of exoplanets were likewise partially confirmed. Finally, the telescope's planned lift-off from Kennedy Space Center was partially confirmed.
