NASA’s Crawler-transporter 2 moves toward the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Friday, Jan. 9, 2026. The crawler will transport NASA’s SLS (Space Launch System) rocket with the Orion spacecraft to Launch Complex 39B ahead of the Artemis II launch which will journey Commander Reid Wiseman,

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.

Just moving out the moon-bound rocket to the launch pad was an incredible engineering feat. Watch how NASA got it done.

The first human spaceflight to the vicinity of the Moon since December 1972 is set to roll out to Launch Complex 39B at the Kennedy Space Center. The Orion spacecraft and its associated Space Launch System rocket,
