 You know, with today's technology, even with SpaceX's Starship, once that gets going, it's a six to seven month trip. And as we were talking about earlier, George, you know, it's very hard on humans to do that, even in a big spacecraft like that. Sure. And then, of course, once you get there, you need to have water and oxygen and all those things. You can get that on Mars, but you have to work for it. You can extract oxygen from the atmosphere. We've done it once on the Perseverance rover. There's an experiment called MOXIE that did that.
