Artemis II Rollback to VAB Timelapse

This timelapse video captures NASA’s crawler-transporter 2, carrying NASA’s Artemis II SLS (Space Launch System) rocket with the Orion spacecraft secured to mobile launcher 1, rolling back Wednesday, Feb. 25, 2026, to the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida to troubleshoot the flow of helium to the rocket’s upper stage, the interim cryogenic propulsion stage. Once complete, the SLS rocket will roll back to Launch Complex 39B to prepare to launch four astronauts around the Moon and back for the Artemis II test flight.
