Moon landing AND back. Several times. No radiation issues in outer space either. Van Allen belt was kind to him.
And escaping moon's gravitational pull on first try, no problem either. Oh, and they left a camera back there to film the space module's ascent back to Earth which captured the launch in real time using 60s technology (radio waves).
- Aldrin went to the moon and back once (not several times, as you claim).
- There were radiation issues, especially with eyesight. All three astronauts could see regular flickers of light due to charged particles hitting their optic nerves. Closing their eyes would make no difference either.
- They were only outside Earth's atmosphere for several days. Not enough time to get fatal radiation dosage. As I can remember, none of the Apollo astronauts died of cancer.
- The Moon's gravitational acceleration was well known for a few centuries before the Apollo missions. Knowing how to escape the Moon's gravity can be worked out by any 1st year undergrad. Thrust required would be much less than that required to escape Earth's gravity.....no atmosphere on Moon, so no worries about drag either.....
- Television cameras and broadcasting equipment existed as far back as the 1930s. Since there are no obstructions between the near side of the Moon and the Earth, it is relatively easy to broadcast the takeoff of a capsule from the Moon's surface. In 1976 (only 7 years later), Viking 1 and 2 broadcast images from Mars using that same "60s technology".....
It is amazing what you can accomplish when you don't watch distracting YouTube videos from people who have no real accomplishments.....level up....
