Mission Space is a ride where you get to experience what it is like to be a real astronaut going to Mars, except you don't have to spend countless years training and your meals don't come in a toothpaste tube or taste like rubber - unless you get the chicken nuggets at Electric Umbrella. All 4 people are given a vital position on the crew - such as Commander, Engineer, Goofy and Cinderella. But don't worry if you get one that you think is beyond your capability. All jobs have the same requirement - basically that you can press a button when it lights up and the commander tells you to push it. (You would not believe how many fail). You get the feeling that the computer engineers could have easily programmed the computer to "push" the buttons automatically, but were just having fun with the macho tourist "astronauts" and letting us feel like we had something important to do. (Kids get a degree in Computer Science.)
Once inside, you immediately feel claustrophobic until the spinning starts and then you frantically look for an emergency stop button. There is an emergency stop button on Virtual Space Mountain at Disney Quest, but this capsule does not have one and mocks you by having hundreds of buttons, switches and knobs that do absolutely nothing when you press them. Remember, this is the only ride in all of Disney World that includes air sickness bags for each passenger (You are expected to bring your own for IASW).
I always get Orange and Green mixed up. Wouldn't you think Green was the spinning one since that is how you look when you exit? Nope - just the opposite. Anyway, even the Green, non spinning can sometimes upset my wife's stomach, so the best bet, if you really want to go to into space, is stick with space mountain - otherwise medical marijuana is now legal here in Florida.
