The orbiter Challenger first launched on STS-6. (STS stands for Space Transportation System.) It rolled out to Kennedy Space Center's pad 39A on December 8, 1982.
The rollout is memorable for the ground fog that created a "fairy land" effect, as seen in the above video.
The video has two clips. The first is the official NASA feed. The second is raw footage shot from a NASA helicopter.
Here are two photos from NASA archives of that fogbound rollout.
