because this will be a really harsh environment. and moondust is pretty rough. yeah, it's really sharp. those are things that we definitely know from apollo. think of taking a glass andjust slamming it down and then crushing it with your feet, and those shards are kind of how it is on the moon since there's no erosion or wind to tumble those little pieces. and that's one of the reasons we're pushing to have suit ports with the spacesuits on the outside of the vehicle. so at the end of these beds back here, there's a door to the vehicle. so you open the door to the vehicle and you're now staring at the back of your suit, and you climb into the back. so now your suit and your cabin are pressurized. you seal it up and then you close the cabin door, so you can go climb in a spacesuit while i stay in here and we don't have to depressurize the cabin.
