Getting a man on the moon was not a feasible aspect for the Soviets. Among the well known memes of almost suicidal material/construction standards and safety precautions, the biggest issue was simple, They just didn't have the engine for it. Initial propositions for the feat was presented shortly after Nasa made the announcement. At the start the plan was for a multitude of launches using the reliable and proven Soyuz rocket, constructing in orbit a trans-lunar vehicle. Then corners started getting cut as time went on. Plans involved conveluted space walks to transfer between vehicles. Soyez test missions were carried out which were cosmonauts teeth would be broken on impact and even the famous story of Gagarin's friend Vladimir Mikhaylovich Komarov death took place during this time, where he screamed in rage at the brass for entombing him in the craft. Development of a Saturn-1 counterpart was also in place, the N1, however the under-funded program was a failure from the start, again, the engine issue. They didn't have a legendary Rocketdyne F-1, still the most powerful rocket engine ever made. So they relied on a couple dozen smaller, less powerful engines for the N-1. This created a spider-web of plumbing and pumps to divert the fuel and liquid oxygen to each of the chambers, resulting in a multitude of issues. There were 4 launches, and 4 massive explosions shortly after. The program was was suspended in '74, and in '76 officially cancelled. Thus ending the Soviet bid to put a man on the moon.
