SLS on the pad

The Moon sets behind NASA’s Artemis II SLS (Space Launch System) rocket and Orion spacecraft atop a mobile launcher at Launch Complex 39B at NASA’s Kennedy Space Center in Florida during the Artemis II wet dress rehearsal on Sunday, Feb. 1, 2026. The wet dress rehearsal allows the Artemis II launch team to run through operations to load propellant, conduct a full launch countdown, demonstrate the ability to recycle the countdown clock, and drain the tanks to practice timelines and procedures for launch. The Artemis II test flight will take Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialist Christina Koch from NASA, and Mission Specialist Jeremy Hansen from the CSA (Canadian Space Agency), around the Moon and back to Earth.
