NASA's Artemis II moon rocket is back on the move, as the space agency prepares the spacecraft for a potential launch before its April deadline.

This is the second time that the 322-foot-tall (98 meters) Space Launch System and Orion capsule stack has rolled out to the launchpad this year, the first having taken place on Jan. 17. But following two wet dress rehearsals and two leaks, NASA decided to wheel the rocket back to the Vehicle Assembly Building for repairs.
