The 12 Greatest Challenges for Space Exploration 

Humanity began in Africa. But we didn’t stay there, not all of us—over thousands of years our ancestors walked all over the continent, then out of it. And when they came to the sea, they built boats and sailed tremendous distances to islands they could not have known were there. Why?

Probably for the same reason we look up at the moon and the stars and say, “What’s up there? Could we go there? Maybe we could go there.” Because it’s something human beings do.

Space is, of course, infinitely more hostile to human life than the surface of the sea; escaping Earth’s gravity entails a good deal more work and expense than shoving off from the shore. But those boats were the cutting-edge technology of their time. Voyagers carefully planned their expensive, dangerous journeys, and many of them died trying to find out what was beyond the horizon. So why keep doing it? And what are the challenges?
