NASA’s Artemis 2 Rocket Rolls to the Pad as Countdown to First Crewed Orion Flight Begins

NASA has moved its SLS rocket and Orion spacecraft to Pad 39B in Florida, marking a key step ahead of Artemis 2—the first crewed Orion flight. The mission, a roughly ten-day free-return circumlunar test carrying three NASA astronauts and one Canadian, will validate life-support and integrated operations ahead of later, landing-focused missions.
