On Monday, NASA will launch the Artemis I moon rocket.
The first mission in a complicated series of missions designed to facilitate further human exploration of the moon and eventually Mars will be launched by NASA on Monday morning.
The Artemis I project will launch an unmanned capsule around the moon for 42 days before it splashes back into the Pacific Ocean.
The first Space Launch Systems mission will be launched during this operation.
Artemis I's main mission: testing Orion's new heat shield as it reenters Earth's atmosphere at 25,000 mph.
The capsule must survive the fiery plunge throughout the process, which is expected to be one of the quickest reentries to date.
The massive SLS rocket is years late and billions of dollars over budget. According to NASA's internal watchdog, the Office of Inspector General, each launch will cost taxpayers $4.1 billion.
The Kennedy Space Center's two-hour launch window begins at 8:33 a.m. Forecasters believe the weather is looking good.
