NASA’s crawler-transporter 2, carrying NASA’s Artemis 2 SLS (Space Launch System) rocket with the Orion spacecraft secured to mobile launcher 1, rolls 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 2 test flight. Image: NASA/Kim Shiflett
NASA hauled its Artemis 2 moon rocket off its seaside pad Wednesday for a slow trip back to a processing facility to track down and fix a helium pressurization problem that has delayed launch of four astronauts on a flight around the moon from this month to at least April 1.
