NASA will reveal the astronauts assigned to its Artemis III mission Tuesday during a major announcement at Houston's Johnson Space Center, giving the public its first look at the crew selected for a pivotal step in the agency's return-to-the-Moon program.

NASA officials are scheduled to provide an update on Artemis III and announce the mission's crew during an event beginning at 10:30 a.m. The announcement comes as NASA works toward a revised Artemis architecture that includes a 2027 mission designed to test critical technologies needed before a future Artemis mission returns astronauts to the lunar surface for the first time in more than 50 years.

Artemis III is scheduled to launch in mid-2027 aboard NASA's Space Launch System rocket from Kennedy Space Center in Florida.
