Leaving Earth is dangerous. Aircraft crash all the time.
Leaving the atmosphere is at least 10X as dangerous. Virgin Galactic and others spending millions to make it safe enough to have a few minutes up in a vacuum and weightless with live passengers.
Getting to orbit uses huge rockets costing hundreds of millions and is at least 10X again more dangerous. Spending any time in space station costs more tens of millions and could mean death quickly by many factors. Just getting back to Earth safely is a real challenge.
Leaving Earth area and orbiting the Moon costs billions, is another 100X as dangerous--you will be gone almost a week and sun storm radiation could kill, equipment could fail, and entering Earth atmosphere will be at tremendous speed.
Landing on moon and walking around for a few minutes is another 10X as dangerous, and costs almost double as just orbiting. Getting back to command ship alive is not very easy at all.
And in all the trips, the surroundings are about being stuck in front seat of a large sedan, or in a station that is like a fair sized apartment. In a space suit, you are packed like a sardine. And in all those places, nothing smells very good at all, you might be nauseous, and the food is not great. I can't imagine how much fun it isn't to use the toilet, even if there is one.
Been watching space progress since early 1958. Being in cockpit of a Navy F4 fighter/bomber and doing carrier landings 51 years ago was more than dangerous enough for me.
Met and talked with astronauts when they visited planetariums where I worked.
