The revolutionary breakthrough will come with rockets that are fully and rapidly reusable. We will never conquer Mars unless we do that. It'll be too expensive. The American colonies would never have been pioneered if the ships that crossed the ocean hadn't been reusable.
In the case of Apple, they did originally do production internally, but then along came unbelievably good outsourced manufacturing from companies like Foxconn. We don't have that in the rocket business. There's no Foxconn in the rocket business.
Some rockets turn faster than others, depending upon the trajectory. In this case it is going to go almost straight up until it is out of sight.
I realized that a methane-oxygen rocket engine could achieve a specific impulse greater than 380.
I always see what’s... wrong. Would you want that? When I see a car or a rocket or spacecraft, I only see what’s wrong. I never see what’s right. It’s not a recipe for happiness.
