Since the mobile launcher returned in October from Launch Pad 39B to the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida, work has been underway for upcoming stacking operations of NASA’s SLS (Space Launch System) Moon rocket.

To prepare for launch, the mobile launcher is undergoing optical scans, system checkouts, and umbilical refurbishment, including installation of the aft skirt electrical umbilicals.

The booster segments soon will move from the Rotation, Processing and Surge Facility to the VAB via a transporter. The aft assemblies, or bottom portions of the five segment boosters, will be situated in the facility’s transfer aisle then lifted atop the mobile launcher in High Bay 3.

The examinations and preparations of the mobile launcher and rocket elements lay the groundwork for Artemis II crewed test flight around the Moon.
