The first moon rocket launch by NASA's Space Launch System was scheduled for Tuesday.
The organization is being forced by Hurricane Ian to move SLS into a vertical steel structure for protection.
The rocket will have to travel 4 miles in 10 hours, which might add another month to its postponement.
To get its new moon rocket to the launchpad, NASA had to overcome administrative obstacles, technological difficulties, and leadership upheavals.
The 30-story-tall, $50 million Space Launch System (SLS) rocket was created by NASA over the course of 17 years to support its new Artemis lunar mission program.
The agency was prepared to attempt its maiden liftoff again on Tuesday after years of delays and two scrubbed launch attempts.
