Humans have dreamed of traveling the stars since the early days of science fiction, and while we’ve managed to set humans down on the moon, launched space stations around Earth, and countless probes have touched down on the alien worlds in our solar system, we’ve been stuck in low-Earth orbit since the end of the Apollo program.
