The trip to Mars is like, what, six months? Is that what the idea is? Yeah, it's about six months. Do you ever anticipate it being quicker than that? Is it possible to make these things faster? Would you have to have solar sails? No, solar sails would be very slow. Would it be? There's only about a six-month period every two years when Earth and Mars are aligned such that you can do the transfer. Yeah, so when you want to go to Mars, you basically accelerate along the same path of Earth, going around the sun, and you time it such that where the tip of the ellipse intersects with Mars, the tip of your ellipse being Mars. And that turns out to be about a six-month journey. I mean, I could sort of see a way to make it happen in, say , three months where the intersection with Mars would not be at the tip of the ellipse but on the edge of the ellipse. Now, that would mean the tip of the ellipse is out near Jupiter. So if you miss Mars, you're going to end up at Jupiter's orbit. That's not good. Yeah, and you're going to be coming in hot.
