The official story, as Bert2theSpark has mentioned, is as follows...
Welcome to the future! In 3016 Forbidden Valley was chosen as the new home for a new space port operated by Galactica - The Universe’s first spaceflight voyager.
Partnering with Air Space Technologies to develop a multi-dimensional portal using the Resort’s iconic flying coaster as the propulsion device, Galactica will send passengers soaring through interstellar space for the first time in history, providing unrivalled access to the limitless wonders of space as never experienced before.
Personally, I think Forbidden Valley needs work. If they were to build upon the theme, it could become one of the best areas in the park, however, since Ripsaw's removal and the closure of Sub-Terra, it has become an area in drastic need of rejuvenation. The two versions could work well together, especially if the park was to expand onto the car park, but more attractions are needed!
