FA, You're a little ahead of the game more than likely. We are more equivalent now to 1975. The moonshot could happen anytime of course in a crisis, but if current trends and cycles continue in a normal way, it could be a few years before we see the rocket launch.
Regarding cycles: The primary ones are 4-4.5 year, 8-9 years, 18 years, 36 years and so on. Three 8/9-year cycles brings up 24 to 27 years, and six 8/9-year cycles brings up 48 to 54 years, which would correspond to the Kondratieff cycle.
If you're looking for a 25-year cycle on gold, I see nothing compelling about the moonshot here.
