NASA’s Nancy Grace Roman Space Telescope arrives at NASA’s Kennedy Space Center in Florida for final preparations before launch. Multiple outlets report the observatory reaches the center on June 21 and begins a prelaunch processing period that is expected to last about 70 days. During this phase, NASA conducts integration and testing steps needed to prepare the telescope for liftoff and operation in orbit. The telescope, described across sources as a $4.3 billion observatory, is intended to join NASA’s roster of major space observatories, following earlier missions such as Hubble, Webb, Spitzer, and Chandra. Launch is planned on a SpaceX Falcon Heavy rocket later this summer. Spaceflight Now specifies a target launch date of no earlier than August 30, while other reports describe the launch timing more generally as occurring later this summer or in August. After the prelaunch work is completed, the telescope will be mounted and prepared for the Falcon Heavy flight to begin its planned science mission from orbit.
