We were a few hundred feet away, very near the VAB (Vehicle Assembly Building), where Artemis was assembled to be then rolled out towards the launch pad.
The Artemis 1 SLS stands 322 feet tall (98 meters) tall and weighs 5.75 million pounds (2.60 million kilograms).
It travels on the Crawler Transporter(CT-2) out to launchpad 39B, about 4 miles away
(this is referred to as "the Rollout")
