NASA issued an Aug. 24, 2026 media advisory describing coverage plans for the prelaunch and launch activities of its Nancy Grace Roman Space Telescope. At that time, NASA and SpaceX were targeting liftoff for no earlier than 7:26 a.m. EDT on Sunday, Aug. 30, aboard a Falcon Heavy rocket from Launch Complex 39A at Kennedy Space Center in Florida. The agency said launch coverage would begin at 6:20 a.m.

The advisory listed a science briefing and a prelaunch news conference for Saturday, Aug. 29, along with in-person interviews, and a postlaunch news conference planned for 9:30 a.m. on launch day. It also described audio-only coverage and website streaming, noting that all times were Eastern and subject to change based on real-time operations.

NASA said Roman is designed to pair sharp infrared vision with a field of view at least 100 times larger than Hubble's, to study dark energy and dark matter, characterize exoplanets and map billions of galaxies. After separation, the observatory was to travel to the second Sun-Earth Lagrange point, about one million miles from Earth. NASA described a five-year primary mission with a goal of 10 years of operation.
