Standing atop the mobile launcher, NASA’s Space Launch System (SLS) rocket and Orion spacecraft arrive at Launch Pad 39B at the agency’s Kennedy Space Center in Florida on March 18, 2022. The Artemis I stack was carried from the Vehicle Assembly Building to the pad – a 4.2-mile journey that took nearly 11 hours to complete – by the agency’s crawler-transporter 2 for a wet dress rehearsal ahead of the uncrewed launch. Artemis I will test SLS and Orion as an integrated system prior to crewed flights to the Moon. Through Artemis, NASA will land the first woman and the first person of color on the lunar surface, paving the way for a long-term lunar presence and serving as a steppingstone on the way to Mars.

The base of the mobile launcher for Artemis I is in view on Launch Pad 3B at NASA’s Kennedy Space Center in Florida on Oct. 23, 2020. Workers on scaffolding are preparing for a launch countdown demonstration. The nearly 400-foot-tall mobile launcher will remain at the pad while engineers with Exploration Ground Systems and Jacobs complete several tasks, including a timing test to validate the launch team’s countdown timeline, and a thorough, top-to-bottom wash down of the mobile launcher to remove any debris remaining from construction and installation of the umbilical arms. Artemis I will test the Orion spacecraft and Space Launch System as an integrated system ahead of crewed flights to the Moon. Under the Artemis program, NASA will land the first woman and the next man on the Moon in 2024.
