NASA is in final installation and technical testing for the Nancy Grace Roman Space Telescope ahead of its August 30 launch on a SpaceX Falcon Heavy.
The 2.4-meter observatory is built to tackle dark energy, dark matter and exoplanets, with NASA saying it could open new research areas across modern astrophysics.
Roman pairs a Hubble-size mirror with a field of view 100 times wider, while its Wide Field Instrument uses 18 infrared detectors to capture vast cosmic scenes in high detail.
A separate coronagraph will block starlight to study nearby planets and test techniques for future searches for Earth-like worlds.
Once at the Sun-Earth L2 point about 1 million miles away, Roman is expected to complement Hubble and James Webb by surveying distant galaxies and finding up to 100,000 new exoplanets.

If Roman finds 100,000 new exoplanets, how will this change humanity's search for life beyond Earth?
What lessons from Roman's on-budget success can be applied to other massive government science projects?

Overview
NASA's Nancy Grace Roman Space Telescope is nearing launch, with final preparations underway at Kennedy Space Center and all necessary funding secured. The telescope, weighing 10,500 kg, will launch on a SpaceX Falcon Heavy rocket, reflecting NASA's shift to competitive fixed-price contracts. This mission marks a transition from years of planning to real progress, as the telescope was already finished and preparing for launch earlier in the year. The selection of Falcon Heavy highlights the substantial nature of the mission and NASA's evolving approach to space exploration.
