The comparison of astronauts to explorers of the past is good, but to a point. While exploration in the age of sail was dangerous, lost sailors still had air to breathe, as well as opportunities for finding water and food. We don't have any of this in space. If something goes wrong, you die. Colonizing planets in space will be a lot harder than colonizing faraway lands on Earth.
