NASA plans to roll its huge moon rocket back to the launchpad at Florida’s Kennedy Space Center on Thursday evening, setting the stage for four astronauts’ much-anticipated journey around the moon.

The Artemis II rocket, which will send astronauts around the far side of the moon, is returning to the launch pad after an issue forced NASA to roll the rocket back for repairs last month.

Teams worked for hours beginning early morning Friday, March 20 to slowly roll the towering Space Launch System rocket across a 4-mile span of the Kennedy Space Center.
