“I think it can be done in, in 30 years. Provided there's an exponential increase in the tonnage to Mars, with each successive Mars transfer windows, which is every two years. So every two years, the planets align, and you can transfer to Mars. So I think in, Roughly 15, but maybe as few as 10, but 10 to fifteen-ish Mars transfer windows, if you're seeing exponential increases in the tonnage to Mars with each Mars transfer window, then it should be possible to make Mars self-sustaining in, in about, quote, roughly 25 years.”
