NASA’s Space Launch System Receives Another Major Boost

The third of five sets of solid rocket boosters for NASA’s Space Launch System (SLS) rocket were placed on the mobile launcher inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida. The middle segments, painted with the iconic “worm” logo, were lifted onto the launcher by Jacobs and Exploration Ground Systems engineers using the VAB’s 325-ton crane.

The twin boosters will power the first flight of the agency’s new deep space rocket on its first Artemis Program mission. Artemis I will be an uncrewed flight to test the SLS rocket and Orion spacecraft as an integrated system ahead of crewed flights.

Mobile Launcher Arrives at Launch Pad 39B for Tests, Preps for Artemis I

The Exploration Ground Systems and Jacobs teams rolled the mobile launcher, atop crawler-transporter 2, out of the Vehicle Assembly Building for its slow trek to Launch Pad 39B at Kennedy Space Center in Florida on Oct. 20.

The roll began just after midnight, and the mobile launcher arrived at the top of the pad Tuesday morning. This trek to the pad will help prepare the launch team for the actual wet dress rehearsal and launch of SLS and Orion on Artemis I next year. The wet dress rehearsal is when SLS and Orion will be rolled out to the pad atop the mobile launcher to practice fueling operations a couple months before launch. The last time the mobile launcher was rolled to the pad was in December 2019.

During its two-week stay at the pad, engineers will perform several tasks, including a timing test to validate the launch team’s countdown timeline, and a thorough, top-to-bottom wash down of the mobile launcher to remove any debris remaining from construction and installation of the umbilical arms.
