Mission: SPACE has two versions, Green Team - "Less Intense Training" and Orange Team - "More Intense Training." They used to use an identical story, both simulating a mission to Mars, though they changed the Green Team show to be an orbit around earth. The other major difference is that Orange Team will spin to create G-forces, similar to a "Gravitron" ride that you might see at a fair. You are completely enclosed in the capsule, so you can't really feel the spinning, but it will press you into your seat. It is important to note that it does not spin the entire time. It does during takeoff, slingshot, and atmosphering entry - each segment lasting about 20 seconds. The capsule also shakes and kind of swings out so you feel pressed against your harness (to feel more like weightlessness). Green Team also shakes and swings, but does not spin at at all.
If you do ride Orange Team, it is advisable to keep your head facing directly forward. Do not turn your head to the side to look at your crewmates. That will mess with your equilibrium. This ride actually has air-sickness bags under the console, so if you need it, know that it's there. It's really not that bad if you can take the 20 second bursts of high G-forces.
