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.
It would be terrific if it could be done while we have President Trump. More media meltdown as they would have to compare him to JFK.
