Walt Disney had the idea for Space Mountain in the early 1960's but he had to wait 11 years for technology to develop to the point that he could actually build the ride.
Space Mountain was the worlds first computer controlled roller coaster. It is an indoor roller coaster that is mostly in total darkness. The ride is supposed to simulate a rocket ship ride through space passed many parts of our solar system.
Disney hired astronaut Gordon Cooper as a creative consultant for the ride.
While the darkness and lighting effects make the ride seem fast it has a relatively low top speed of 28 miles per hour nearly matching the little kids roller coaster ride Goofy's Barnstormer at 25 mph. In comparison the Splash Mountain coaster reaches 40 miles per hour. The current worlds fastest roller coaster, Formula Rossa at Ferrari World in Abu Dhabi reaches a top speed of 149 mph.
Gordon Cooper was a NASA astronaut who flew twice in space, during the Mercury and Gemini programs. On his last flight, Gemini 5, Cooper and crewmate Pete Conrad set what was then a world endurance record of the time of 190 hours 56 minutes.
Cooper flew on Mercury 9, the last flight of the Mercury program. His flight flew 22 orbits around the earth in 34.5 hours.
Cooper later commanded the Gemini 5 mission which set a record by spending 8 days in space and traveling 3.3 million miles in orbits around the earth.
Gemini capsules were launched into space on board Titan II rockets that reached top speeds of 18,030 mph.

Dupont. The booster was used to launch the Gemini VSpacecraft from Cape Kennedy, Florida, and re-entered the earth's atmosphere 450 miles N.E. of Cape Kennedy.
