You show a Hollywood quote, I'll raise you a better one:
Space: the final frontier. These are the continuing voyages of the starship Enterprise. Their ongoing mission: to explore strange new worlds; to seek out new lifeforms and new civilizations; to boldly go where no man has gone before
You missed the 'volunteer' part it seems. People have volunteered for expeditions with uncertain outcomes since, well, forever. Some people do their utmost best to tempt fate by climbing skyscrapers and masts without any safety devices, they jump off cliffs in clothing which gives them a slight advantage over gravity, they get into devices which are supposed to keep them alive at depths which would crush them to ¼ of their size if they were to be exposed and more. People used to embark on sailing vessels to trek to unknown places, a practice which started when sailing vessels became a thing. People want to explore frontiers and some people are willing to take great risk to be among the first to do so.
No silly quote from a Hollywood production will keep them from following their drive to boldly go where no man has gone before. Or woman, for that matter.
