00:00The Artemis II Space Launch System, the SLS, has started its rollout from one of
00:04NASA's most iconic buildings, the Vehicle Assembly Building, or VAB. The
00:09place is basically a rocket cathedral. Standing at 525 feet tall, the building
00:15comes in as the tallest single-story structure on Earth. The VAB has been at
00:20the center of every major human spaceflight era. Saturn V for Apollo, the
00:25Space Shuttle for decades, and now SLS for Artemis. Artemis II is stacked in
00:29inside the VAB's High Bay 3 on its mobile launcher like a skyscraper made of
00:35rocket stages. Those doors are now open, with the crawler rolling slowly toward
00:40Launch Complex 39B, and then the moon.
