Technicians at NASA’s Payload Hazardous Servicing Facility at Kennedy Space Center in Florida offload eight high‑efficiency particulate air (HEPA) wall modules and other ground support equipment on Monday, April 27, 2026, as part of preparations for arrival of NASA’s Nancy Grace Roman Space Telescope. Each 1,800‑pound module enhances the 40-year-old facility’s clean room systems, helping meet the telescope’s stringent cleanliness requirements during prelaunch processing. Teams are targeting launch as soon as early September aboard a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA Kennedy.
