People have read stories and watched movies about outer space for decades.
They have enjoyed tales of space travelers, friendly invasions, and hostile encounters with beings from other planets. The characters were larger-than-life heroes or villains. The rocket-powered spacecraft explored the universe or exploded into smithereens. But Earth also has real-life space travelers. Their real-life journeys range from successes to failures. What they have in common is the courage to ride a rocket into the unknown.
