One of the key episodes of the Cold War was the space race between the Soviet Union and the United States, which culminated in man's landing on the moon in July 1969. Today there is a certain consensus that this race with political undertones boosted scientific research to unprecedented levels, and a series has recently been released, For all mankind, which asks what would have happened if the Soviets had landed on the Moon before the Americans did. Well, at present, the closest thing to that race of the second half of the twentieth century is the competition between three billionaires, Richard Branson, Jeff Bezos and Elon Musk, to be the first to exploit so-called space tourism, that is, allowing anyone to fly beyond the atmosphere and see the planet Earth from space.
