Billionaire's battle over space
SpaceX founder Elon Musk has defended the so-called space race among some of the world’s richest men, saying space represents hope for so many. The comments came one day after Virgin Galactic founder Richard Branson made history as the first person to blast off in his own spaceship. He beat Jeff Bezos, the richest person on the planet, by a slim margin – just nine days. Bezos will follow Branson's lead and head to space on Blue Origin's New Shepard's 16th flight into space.
