Are there dangers in going to space?
O course there is.
Going to space always has dangers. Going to the Moon in 1969 had plenty of dangers but NASA Neil Armstrong etc still diid it anyway, were very successful and the astronauts came back to earth safely and lived very long happy lives after that.
The point is NASA and other countries has steadied the Moon more than any other object in space. They are not starting a Moon Gateway just based on knowing nothing the moon. They are doing it based on deep knowledge acquired over decades.
