CAPE CANAVERAL, Fla. – Modifications continue on the Multi-Payload Processing Facility, or MPPF, at NASA's Kennedy Space Center in Florida. Inside the MPPF annex building, construction workers are converting the building to a ground support equipment storage area and work area. The pipes overhead are part of the Environmental Control System. Kennedy's Center Operations Directorate is overseeing upgrades to the MPPF for the Ground Systems Development and Operations Program. The extensive upgrades and modernizations will support processing of Orion spacecraft for NASA's exploration missions. The 19,647-square-foot building, originally constructed in 1995, primarily will be used for Orion hypergolic fueling, ammonia servicing and high-pressure gas servicing and checkout before being transported to the Vehicle Assembly Building for integration with the Space Launch System.
