FULL STORY ======================================================================

NASAs next space telescope, the Nancy Grace Roman Space Telescope, arrived at Kennedy Space Center in late June ahead of its scheduled launch on Aug. 30 atop a SpaceX Falcon Heavy from Launch Complex 39A. Since its arrival at the Cape, the telescope has achieved several launch-processing milestones, including being moved to the Payload Hazardous Servicing Facility and flipped vertical.

Throughout the next weeks, Roman will undergo solar panel deployment tests, insulation and thermal tests, and more to validate the telescopes systems. Following launch, the spacecraft will travel to the Sun-Earth Lagrange Point
2 (L2), where it will conduct wide-field surveys in near-infrared and visible wavelengths.



Constructed and operated by NASAs Goddard Space Flight Center in Greenbelt, Maryland, Romans inner and outer segments were joined in November 2025, marking the telescopes completion. After final testing, checkouts, and packaging were completed, the telescope was ready to be transported to the Kennedy Space Center (KSC) for final launch preparations and launch.

Riding in a protective, environmentally controlled transportation container aboard NASAs Pegasus barge, Roman traveled from Maryland to Florida, arriving at KSCs turn basin on June 21. The 8,200 kg telescope moved to the Payload Hazardous Servicing Facility (PHSF), which had received upgrades in anticipation of Romans arrival.

To reduce the risk that contaminants from the telescopes trip to Florida
would affect future telescope operations, technicians completed an initial cleaning outside the PHSF, followed by another cleaning within an airlock inside the facility. Furthermore, the PHSFs air filtration system scrubbed
the air around the telescope, allowing technicians to safely open the transport containers inner door and expose the telescope to the PHSFsenvironment for the first time.

Days after its arrival at KSC, PHSF technicians removed the containers cover and moved Roman to the facilitys high bay. In the high bay, teams rotated Roman from its horizontal transport position to the vertical position. The following day, large cranes lifted the telescope onto a work platform named the Pantheon. Placing the telescope on the Pantheon gives technicians access to critical telescope components that need to be tested and validated ahead
of launch. Roman is rotated to the vertical position inside the PHSF.

Once on the Pantheon, technicians powered on Roman and its subsystems for the first time since it left Goddard to conduct system checkouts. See Also Roman Space Telescope Updates Space Science Coverage Click here to Join L2

With less than two months left until its targeted launch date, Roman has just a few prelaunch milestones to complete before its ready for launch. Technicians are expected to test the telescopes six solar array panels, inspect and test its insulation systems and thermal blankets, and test its propellant tanks in the coming weeks. Once those tests are complete, technicians will fuel Roman, filling its propellant tanks with approximately 290 gallons of hydrazine. This fuel will enable the spacecraft to perform trajectory-correction burns en route to L2, orbital-correction burns at L2, and most importantly, maneuvers for observations.

After Romans systems have been validated and its propellant tanks filled, the telescope will be encapsulated in a fairing and transported to Launch Complex 39A (LC-39A) for integration with its Falcon Heavy rocket at SpaceXs Horizontal Integration Facility (HIF).

Roman is scheduled to launch on Sunday, Aug. 30, at a yet-to-be-determined time from LC-39A around nine months earlier than initially expected. The two Falcon Heavy side boosters will perform return-to-launch-site landings, with one landing at Landing Zone 40 (LZ-40) and the other at Landing Zone 2
(LZ-2), both located on the grounds of the Cape Canaveral Space Force
Station. It is currently unknown whether or not SpaceX will attempt to
recover the center core.



Once at L2, Roman will undergo a multi-month commissioning phase to ensure
the telescope, its subsystems, and its instruments are functioning properly following launch. Using two instruments the Wide-Field Instrument (WFI) and the Coronagraph Instrument (CGI) Roman will conduct three main wide-field surveys and search for exoplanets. The telescopes capabilities will allow scientists to map billions of galaxies and collect data that will be analyzed for decades to come.
