Do you think it will be easier or harder to build an O'Neill cylinder than a Mars colony? If easier, then I think Moon makes more sense; can be used as supply depot and dry dock for manufacturing.
i appreciate any billionaire addition to the human potential club but this is extremely not true. there’s almost nothing of value on the moon and it can’t (practically speaking) be terraformed. given current technology, mars is the only way forward.https://twitter.com/trengriffin/status/1086740028951162881 …

much much much harder. in terraforming, mars does most of the work itself. mainly what we need to do is warm the southern polar ice cap (frozen CO2).

I consider the things we build to get to the moon, as part of the value proposition of going. The space race was tremendous for material sciences, among many other fields. Mars gets the same benefit, of course.

we’ve already built those things! we’ve had the technology to go to mars and start colonizing for 50 years. time to do it.

Plenty of aluminum and water on the moon. Don't see why you'd go for the moon instead of asteroids though. Asteroids have many more advantages

Mars is the best place to mine if you want to build anywhere above LEO. It’s got abundant resources and “easy” methane fuel ISRU, and it’s 10x easier to launch from than
. The moon can only supply hydralox fuel, and that only at high costs - Show replies

100% agree. When I hear advocacy for going to the moon first, I observe either ignorance or weak / insincere commitment to space exploration. The delta V required to land on moon is roughly equivalent to that needed to reach Mars. This is the real bottleneck not distance.

The Moon is full of the same material resources as the Earth with a fraction of the gravity and zero atmosphere. Launching completed tech/products (either to Mars or back here to Earth) would cost basically nothing.
