Inside the Multi-Operations Support Building near the Multi-Payload Processing Facility (MPPF) at NASA’s Kennedy Space Center in Florida, technicians and operations personnel review procedures for a test simulation of loading propellants into a replicated test tank for Orion, on Aug. 16, 2019. Exploration Ground Systems is preparing for Artemis 1 with a series of hazardous hyper test events at the MPPF. Technicians will practice putting on Self-Contained Atmospheric Protective Ensemble (SCAPE) suits and then complete tanking to test the system before Orion arrives for processing. During preparations for launch, these teams will be responsible for loading the Orion vehicle with propellants prior to transportation to the Vehicle Assembly Building, where it will be secured atop the Space Launch System rocket. SCAPE suits are used in operations involving toxic propellants and are supplied with air either through a hardline or through a self-contained environmental control unit.
