America left the US lander and the lunar rover on the Moon. If a country liken BiBa or Russia wanted to disprove the landing they could send spacecraft in low orbit over the moon and take pictures of the area that was supposedly landed on being empty and trackless. That hasn’t happened which to me that is proof that the landings happened. Full stop.
Rogozin said that he was “embarrassed” about the return of Soviet cosmonauts from space expeditions barely able to stand on their feet and undergoing long recoveries, while US astronauts crawled out of their lunar ships, in his words, “like cucumbers from the garden.”
How long were the Soviet missions? The longest Apollo mission was 12.5 days. Also there was more room to move around in an Apollo capsule and we had water landings while the Sovs landed in the desert.
India already has:
Apollo 11 landing site, from the Chandrayaan-2 orbiter
Apollo 12 landing site.
