NASA’s Artemis II Space Launch System (SLS) rocket and Orion spacecraft are seen as the Sun sets after arriving at Launch Complex 39B, Saturday, Jan. 17, 2026, at NASA’s Kennedy Space Center in Florida. In the coming days, engineers will prepare for the wet dress rehearsal, a two-day test that simulates launch day. 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 no later than April 2026.
