US-SPACE-ARTEMIS II

Mobile launcher 1 containing the massive Artemis II Space Launch System (SLS) rocket and Orion spacecraft arrives at the Vehicle Assembly Building from Launch Pad 39B after a rollback that lasted over ten hours at the Kennedy Space Center in Cape Canaveral, Florida, on February 25, 2026. NASA said on February 25 that it would roll its 322-foot (98-meter) SLS rocket off the launchpad in Cape Canaveral, Florida after teams detected issues with helium flow. The decision means further delays for the highly anticipated Artemis 2 mission, which will last approximately 10 days and see three Americans and one Canadian fly around Earth's satellite.
