NASA’s Space Launch System (SLS) solid rocket boosters have grown taller with the addition of the fifth and final pair of motor segments in preparation for the launch of Artemis I later this year. At NASA’s Kennedy Space Center in Florida, engineers with Exploration Ground Systems lowered the final solid rocket booster into place on the mobile launcher on Feb. 23. Up next, the nose assemblies will be placed atop the segments to complete the boosters. The twin boosters will power the first flight of the agency’s new deep space rocket during the launch of Artemis I. This mission is an uncrewed flight to test the SLS rocket and Orion spacecraft as an integrated system, preparing the way for Artemis II and other crewed flights to the Moon.
