Managers from NASA’s Exploration Ground Systems (EGS) and SLS (Space Launch System) Programs hold a baton signifying the hand off of the SLS interim cryogenic propulsion stage to Kennedy’s EGS Program inside the Multi-Payload Processing Facility at NASA’s Kennedy Space Center in Florida on Monday, March 10, 2025, after being transported from United Launch Alliance’s Delta Operations Center at nearby Cape Canaveral Space Force Station. Teams with EGS will begin fueling the upper stage inside the facility ahead of the agency’s Artemis II mission. The interim cryogenic propulsion stage is a liquid oxygen and liquid hydrogen-based system that will fire its RL10 engine to give the Orion spacecraft the big in-space push needed to fly around the Moon and back.
