Artemis 2 is scheduled to launch in the coming weeks with four astronauts who will spend ten days in orbit around the Moon.
Artemis 2 will be the first human flight beyond low Earth orbit since Apollo 17 in 1972 if it launches as planned.
Artemis 1 required three wet dress rehearsals between April and June and scrubbed its first two launch attempts in late summer because of propellant leaks.
Artemis 2 is the first crewed mission of the Artemis lunar exploration campaign and will carry three Americans and one Canadian.
Building Mobile Launcher 2 rather than modifying the first platform will allow the first platform to be used for additional SLS Block 1 flights.
