I think people can value different things. Because you value things that are different from someone else doesn't make them wrong. You can say that the perceived and actual risk are two high for me to take the chance. But it feels like you're not respecting the autonomy of the children or the astronaut.

I also don't understand what you mean by "no right to make that decision". It sounds like you mean, parents are never justified in taking risks that involve the potential for death, even if their family is on board.

So I asked my parents about this since it's only been like 10 years since they've been 50. My mother said that if it's her job and she's been involved in this for a long time she would go. And that she would just have a conversation with her children. She also said it would be way better than joining the military or being a black hawk pilot. My dad would be super on board to go to the moon.
