Artemis II crew and backup crew hold a banner with NASA and industry leaders during a supplier and media day event on Monday, Dec. 16, 2024, inside the Vehicle Assembly Building at the agency’s Kennedy Space Center in Florida. The Artemis II crew and backup crew participated in the event days after teams with NASA’s Exploration Ground Systems transport lifted the agency’s 212-foot-tall SLS (Space Launch System) core stage from the facility’s transfer aisle into High Bay 2 where it will remain while teams stack the two solid rocket boosters on top of mobile launcher 1.
