And Moon by 2024?! More lies and deceit!
We destroyed the technology! Van Allen belts!
This reads like sarcasm, just needed to add something about your tinfoil hat.
If you destroy your car, can we no longer make any new ones?
The technology is actually way more accessible than it was back then, but our tolerance to risk (both financial and human life) has decreased. This means that NASA will not allow people to fly on the technology we had back then, it would have to be WAY safer first.
Also, the Van Allen belt is just what it says. Its a belt, not a barrier or a sphere. This means you can go around it to miss the most energetic part of it. . . just the way they did it during the Apollo missions.
Further, radiation does not work the way you think it does.
