First Umbilical for ML2

The first umbilical – one of many swing arms that will provide power, communications, and propellants to a larger configuration of NASA’s Space Launch System (SLS) rocket – for the agency’s mobile launcher 2 (ML2) arrives at the Launch Equipment Test Facility (LETF) at NASA’s Kennedy Space Center in Florida on Oct. 28, 2021. The umbilical will go through rounds of testing at the LETF to verify it functions properly before getting installed on the ML2 tower. This particular umbilical will provide propellants, environmental control systems, and a variety of purge gasses to the rocket’s Exploration Upper Stage. ML2 will be used to launch SLS Block 1B and Block 2 configurations to the Moon, starting with the Artemis IV mission, allowing NASA to send astronauts and heavy cargo to the lunar surface.
