Artemis I WDR Update: Final Umbilical Preparations Complete for Artemis I

Final preparations on the umbilicals to ensure connectivity between the mobile launcher, the Space Launch System rocket and Orion spacecraft were completed this evening.

The umbilicals provide power, communications, coolant, and fuel to different parts of the rocket. Additional accessories provide access and stabilize the rocket and spacecraft. During launch, each umbilical releases from its connection point, allowing the rocket and spacecraft to lift off safely from the launch pad.

Teams have also completed a final walkdown at the pad to verify the rocket and ground equipment are in the correct configuration for tanking operations checking to ensure no foreign object debris is present near the rocket that could present a hazard during the test.

The next update will be provided in the morning of April 14, prior to the mission management team’s pre-tanking briefing where they will review the status of operations and determine if they are “go” to proceed toward tanking operations.

Real-time updates will be provided on the Exploration Ground Systems Twitter account with “go” for tanking targeted on April 14. NASA is also streaming live video of the rocket and spacecraft on the Kennedy Newsroom YouTube channel.
