Overview
- The Nancy Grace Roman Space Telescope arrived at Kennedy Space Center on June 21 and was transferred into the Payload Hazardous Servicing Facility to begin final launch processing.
- NASA is targeting a no-earlier-than Aug. 30 launch on a SpaceX Falcon Heavy from LC-39A, a date the agency says moves the program roughly eight months ahead of its formal May 2027 commitment.
- Technicians will run a roughly 70-day campaign that includes cleanroom servicing, testing the observatory’s six solar arrays, inspecting thermal blankets, loading about 290 gallons of hydrazine propellant, and encapsulating Roman for launch.
- The telescope’s sea transport saw two onboard cooling units struggle, forcing an unscheduled stop to add rental chillers, a handling issue NASA says has been addressed but that highlights schedule risk during processing.
- Roman carries a 300-megapixel Wide Field Instrument and a coronagraph demonstrator designed to survey billions of galaxies, find hundreds of thousands of exoplanets, and study dark energy from the Sun–Earth L2 point, and any delays could ripple across summer launch plans and science timelines.
