This has really been bothering me..

The first time I was in the queue for Mission:Space, I saw the giant rotating circle, and was certain it was part of the set from Horizons with the floating boy and his dog. When I mentioned this to a cast member, they said it wasn't that, and that it was instead a set piece from Mission to Mars. I believe them, but at the same time, it seemed like an awfully big coincidence. Does anyone know if this is definitely true?

The 'gravity wheel' is from the 2000 film Mission to Mars. I also know there is a 'nod' to Horizons ON the wheel (the Horizons logo is on display at the center of the wheel). So you are kind of both right :)
