The space-age idea is all hype to raise money for who knows what. After all, even if it were safe, how many of us will ever get to go, right?
Back in the 1950s, there was all kinds of propaganda pushed about how the then-children would be flying all over the solar system and further when they became adults. Many of those "then-children" have died of "old-age" without even seeing the beginnings of what they envisioned as children.
Go back and look at the science-fiction books from back then. Check the dates on the stories listed at
http://www.luminist.org/archives/. There are loads of sci-fi books listed there. The biggest sci-fi of all was the idea that we would be going. And now they are starting the sci-fi all over again.
Back in the 1950s and early 1960s, they had a method to go anywhere in the solar system and beyond. They had the beginnings of a practical program for "going where no-one has ever gone before." But instead of developing it into something practical and safe, they cancelled it. See

The whole space idea is hype designed to get people to willingly give of their time and money so some companies can get richer.
