The Artemis II crew is inside the rocket and ready for launch to the Moon from the Kennedy Space Center in Florida.
The Space Launch System rocket is poised to blast off Wednesday evening with a two-hour launch window beginning at 6:24 p.m. EDT.
Artemis astronauts Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen will be on board. They’ll hurtle several thousand miles beyond the moon, hang a U-turn and then come straight back.
