A SpaceX Falcon Heavy rocket is set to launch NASA's Nancy Grace Roman Space Telescope from Florida's Space Coast on Sunday, Aug. 30, 2026. The rocket will carry the telescope, which has a field of view at least 100 times larger than the Hubble Space Telescope. The launch is expected to produce a sonic boom audible in parts of Northeast Florida, including Jacksonville Beach.
The rocket will lift off from Kennedy Space Center or Cape Canaveral Space Force Station, but the sonic boom and plume from the launch could be visible hundreds of miles away. On July 9, 2026, residents in Collier and Leon counties reported seeing the "space jellyfish effect"—a phenomenon caused by sunlight reflecting off rocket exhaust. That launch occurred at 5:21 a.m. and was visible during sunrise.
Visibility of the Falcon Heavy launch will depend on weather, cloud cover, and the rocket's trajectory. If conditions are clear, the plume may be seen as far south as West Palm Beach and as far north as Jacksonville Beach. The "space jellyfish" effect typically occurs during sunrise or sunset launches when sunlight interacts with the rocket's exhaust.
Residents in Jacksonville and other areas are encouraged to check NASA+ content on Amazon Prime Video for real-time updates. Nighttime or early morning launches offer unique photo opportunities, as the rocket's glow will light up the dark sky. The Nancy Grace Roman Space Telescope is designed to study dark energy, exoplanets, and other cosmic phenomena, marking a major advancement in space observation.
