NASA Artemis I Umbilical Release and Retract Test

Engineers at KSC successfully completed the Umbilical Release and Retract Test on Sept. 19 inside the Vehicle Assembly Building (VAB) in preparation for the Artemis I mission. During the test, several umbilical arms extended to connect the Space Launch System (SLS) rocket and the mobile launcher. They swung away from the rocket, just as they will on launch day. The umbilicals will provide power, communications, coolant, and fuel to the rocket and the Orion spacecraft while at the launch pad until they disconnect and retract at ignition and liftoff.
