The 10 booster motor segments that will form the NASA Space Launch System rocket’s twin, five-segment solid rocket boosters for the agency’s Artemis II mission, arrive at Kennedy Space Center on Thursday, Sept. 28, 2023. Due to their weight, the booster motor segments traveled by rail across eight states in specialized transporters to the Florida spaceport. Teams with NASA’s Exploration Ground Systems will process each of the segments at Kennedy in preparation for launch. Artemis II astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen will blast off from Kennedy, traveling around the Moon on the first crewed mission under Artemis that will test all of the Orion spacecraft’s systems.

Eight of the 10 solid rocket booster motor segments for NASA’s Artemis III SLS (Space Launch System) rocket arrive at a rail yard near the agency’s Kennedy Space Center in Florida on Monday, June 8, 2026. The solid rocket boosters traveled by train in specialized transporters to the Florida spaceport and will be transferred from the rail yard to NASA Kennedy’s Rotation, Processing and Surge Facility for processing. The Artemis III mission will launch crew in the Orion spacecraft on top of the SLS rocket to test rendezvous and docking capabilities between Orion and commercial spacecraft needed to land astronauts on the Moon.
