Members of NASA’s mission management team, launch team, and contractor Jacobs participate in the 11th terminal countdown simulation for the Artemis I launch inside Kennedy Space Center’s Launch Control Center on Oct. 14, 2021. It marked the first time these teams conducted the simulation together. During Artemis I, the agency’s Orion spacecraft will lift off from Kennedy aboard NASA’s most powerful rocket – the Space Launch System – to fly farther than any spacecraft built for humans has ever flown. Through NASA’s Artemis missions, the agency, along with commercial and international partners, will establish a sustainable human presence on the Moon to prepare for missions to Mars.
