Crossing large spans of water was very dangerous, because of storms, getting lost, running out of food etc. Nowadays, crossing large spans of empty space is also very dangerous, but the dangers are a bit different. Regardless, I can see many similarities between crossing the Atlantic ocean in the 1400s and going to the moon 500 years laters.
Although you could travel the land. Perhaps not cross the Sahara but if you lived in the Roman world, you could quite easily take some years to walk off the edge of the map and just explore. There would of course be a good chance of death from illness, animal or person, but equally like today, you may also meet plenty of kind people who would let you stay and maybe even share their knowledge of the area and culture.
I like the idea that some people did. Just disappeared into the unknown on an adventure, found happiness and success there and never returned.
It was a lot later (1300s), but Ibn Battuta seems to have done just that. Guy leaves Morocco and just keeps going on and on, till he ends up in China. Though perhaps even more incredibly he actually does come all the way back. The historicity of his accounts is disputed and maybe only a part of it is true, but even if he only got as far as India, I still find it fascinating to imagine doing at that time.
There are viking inscriptions and stuff at the hagia sophia, that's a hell of an adventure for the time!
there is an infinite difference between "you can technically do it but you're 99% likely to die" and "you literally cannot even reach the edge of the atmosphere without a vehicle engineered and built by 5000 people"
You’re right that there are many big differences. Launching a rocket into space could be compared with building a major cathedral back in the day. People did both, but not very often, because those projects are very demanding. Ships were also super expensive, but we built those all the time, so obviously the requirements weren’t quite as high.
Also attitudes have shifted quite a lot in the recent centuries, so losing a few sailors isn’t quite the same as losing an astronaut. Nowadays, safety is taken a lot more seriously which makes the project even more expensive.
