NASA’s powerful SLS (Space Launch System) rocket core stage for the Artemis II mission arrived on Tuesday, July 23, at the agency’s Kennedy Space Center in Florida. The core stage will help power SLS when it launches four astronauts around the Moon for the first crewed flight of SLS and the Orion spacecraft during the Artemis II test flight.

The core stage, aboard NASA’s Pegasus barge, traveled from the agency’s Michoud Assembly Facility in New Orleans and spent seven days coasting through the Gulf of Mexico and then the Atlantic Ocean before arriving at NASA Kennedy’s Complex 39 turn basin wharf.

The 212-foot-tall SLS core stage, its propellant tanks, avionics, flight computer systems, and four RS-25 engines, were manufactured and assembled at NASA Michoud. Now, teams with NASA Kennedy’s Exploration Ground Systems Program will prepare the rocket stage for integration ahead of launch.

The only rocket that can send the Orion spacecraft, astronauts, and supplies to the Moon on a single launch is the Space Launch System. Its core stage provides more than two million pounds of thrust and the whole rocket provides 8.8 million pounds of thrust to launch Artemis II to the Moon.

Up next, the core stage will roll to NASA Kennedy’s Vehicle Assembly Building, where teams will process it until it is ready for rocket stacking operations.

Follow the livestream of the core stage offload online expected to begin at 9 a.m. Wednesday.
