The train carrying the two solid rocket boosters that will power NASA’s Space Launch System (SLS) for Artemis missions to the Moon arrives at the Jay Jay rail yard – the connecting link between Kennedy Space Center and the Florida East Coast railway – in Titusville, Florida, on June 12, 2020. The boosters, each comprised of five motor segments, traveled from a Northrop Grumman manufacturing facility in Promontory, Utah, to Kennedy’s Rotation, Processing and Surge Facility, where teams with NASA’s Exploration Ground Systems will process the segments before moving them to the Vehicle Assembly Building for stacking on the mobile launcher. Under the Artemis program, NASA will land the first woman and the next man on the Moon by 2024. The first in a series of increasingly complex missions, Artemis I will test the Orion spacecraft and SLS as an integrated system ahead of crewed flights to the Moon.
