Since we did this 50 years ago, and technology has greatly advanced since then, shouldn’t this be a simple job, to return to the moon? They really need many years of prep time to do this?
Back in the 60s, NASA didn't have multiple missions like "Muslim outreach"
My guess is that the rockets will need to be built again from scratch, and while we have better technology, these things are sure to take time. Just testing alone will take years. Still, I like the idea of going to the moon. Investing in science and space exploration is much better than trying to stop cows from farting.
We didn't have to meet diversity quotas 50 years ago, EPA regulations, or (fill in the blank make work regulatory agency) requirements ...
The technology is pretty well understood. It takes time and money to turn technology into working hardware, particularly since we wouldn’t just be copying stuff built 50 years ago. (Reverse engineering the old stuff would be even more expensive and take longer.)
