A grainy black-and-white image plays across the screen in one of Bob Richards’s earliest memories—spacesuits, a lander and astronauts Neil Armstrong and Buzz Aldrin taking their historic first steps across the lunar surface. Richards, who was barely out of his toddler years at the time, recalls sitting in his family living room north of Toronto while his dad futzed with the rabbit-ear antenna, trying to improve the broadcast streaming over from Buffalo, N.Y. “Apollo 11 was a defining moment for humanity,” says the founder and CEO of Moon Express, a company that hopes to sell transportation to our natural satellite and eventually mine materials there. “The inspiration of Apollo is very prominent in what’s happening today in space.”
