The Artemis II mission will set several notable human spaceflight records. Astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen will travel farther from Earth than any human in history. They won’t land. That distinction will fall to the next mission in line in NASA’s Artemis program.

With Artemis II, SLS could become the most powerful rocket ever to launch humans. Its four main engines burn roughly 700,000 gallons of ultra-cold fuel, producing enough oomph to keep eight Boeing 747s aloft. Future versions of SLS, if they come to fruition, could deliver even greater power.

Ahead of the historic mission which will return humans around the moon, NASA's giant SLS rocket is set to roll to the KSC launch pad for testing.

NASA has confirmed the upcoming milestones for its historic Artemis II mission—the first crewed flight of the Space Launch System (SLS) rocket and Orion spacecraft, sending four astronauts on a lunar flyby for the first time in over 50 years—with rollout and Wet Dress Rehearsal (WDR) to set the stage for a potential launch in February.

The crawler carrying the SLS rocket and Orion spacecraft was built 60 years ago to haul NASA’s Saturn V rockets, then kept around for the Space Shuttle Program. Now, the vehicle is back to its original purpose of positioning Moon-bound rockets on their launch pads.

First journey around moon with astronauts in more than 50 years could blast off in February
