Grace Roman

• NASA is scheduled to launch the Nancy Grace Roman Space Telescope on August 30, 2026, using a SpaceX Falcon Heavy rocket. • The telescope features a mirror similar in size to Hubble's but possesses a field of view approximately 100 times wider, allowing it to map dark energy and search for exoplanets. • By monitoring roughly 200 million stars for gravitational microlensing, the mission aims to discover over 1,000 planets, specifically targeting cold, distant worlds that current detection methods often miss.

• NASA engineers have successfully completed the final inspection of the Nancy Grace Roman Space Telescope's primary mirror, which passed all tests. • Following this final check, the telescope is now being prepared for shipment to its designated launch site in Florida. • This milestone ensures the telescope's optical systems are fully operational before it begins its mission to study dark energy and exoplanets.

• NASA announced in December 2025 that construction of the Nancy Grace Roman Space Telescope is complete, with a scheduled launch by May 2027 or potentially as early as fall 2026. • During its five-year primary mission, the observatory aims to discover approximately 100,000 new transiting planets and create the largest catalog of rogue worlds in history. • This mission is significant because it will drastically expand the known exoplanet population and provide unprecedented data on planets drifting without host stars.
