I don’t want a repeat of the Apollo program: a flag-and-footprints mission where we go there, look around, and then come home for another 40 years. I want to go there and stay there. Apollo was done as a race, and the goal of a race is to win. It wasn’t sustainable. We need to be able to figure out how to get there and be there, and that takes more than just big rockets. We need a good plan, and I’m not really sure what we had up until this point is that plan.
Building a heavy-lift rocket that can take us to the Moon, Mars, and near-Earth asteroids is not really easy. It’s not like we can dust off the old Saturn V plans and start up the factories again. All that tech is gone, superseded, and we might as well start from scratch with an eye toward newer tech. This budget is calling for that, as well as relying heavily on private companies.
