NASA’s gigantic Space Launch System moon rocket, topped with an uncrewed astronaut capsule, began an hours-long crawl to its launchpad Tuesday night ahead of the behemoth’s debut test flight this month.
The 322-foot-tall rocket is scheduled to embark on its first mission to space–without any humans—on Aug. 29. It will be a crucial, long-delayed demonstration trip to the moon for NASA’s Artemis program, the United States’ multibillion-dollar effort to return humans to the lunar surface as practice for future missions to Mars.
