Space is very similar in track type to Matterhorn, in that you are taken up the the top and then basically you coast around in spirals to the bottom, with a few bunny hills in there. There are
YouTube videos, I believe, of people who were on Space when it broke down, and they turned on the lights and basically give the vehicle a shove to get it to coast down to the bottom. So you can see what the ride looks like with lights on. However, as the previous posters have said, it’s much smoother than Matterhorn. It mostly goes in spirals to the right, so especially if you’re seated on the left side, you’ll get shoved into the side of the vehicle on the left. I came home with bruises on my left thigh and arm when we were there a few weeks ago. I love it, though, esp the Hyperspace version! Also, I read somewhere that because you’re in the dark, you feel like you’re going super fast, but really it’s not a very fast roller coaster- like 35 mph, I think?
DH used to love coasters, but he finds Space too intense now. However, he loves BTMRR. It’s fun but not really scary, the drops are not humongous. It’s very noisy, though, esp in the tunnels!
