The maiden voyage of SLS is set for November 16, kicking off NASA's return to the Moon and setting the stage for crewed missions.
The launch of the SLS megarocket will kick off a series of missions in which NASA seeks to return humans to the Moon.
The dress rehearsal for Artemis 1 starts on Saturday, with propellant loading expected on Monday.

Artemis astronauts will require sophisticated vehicles to support their lunar expeditions.
