There’s a new space race – will the billionaires win?

If there is one thing we can rely on in this world, it is human hubris, and space and astronomy are no exception. Illustration: Elia Barbieri/The Guardian The ancients believed that everything revolved around Earth. In the 16th century, Copernicus and his peers overturned that view with the heliocentric model. Since then, telescopes and spacecraft have revealed just how insignificant we are. There are hundreds of billions of stars in our galaxy, the Milky Way, each star a sun like ours, many with planets orbiting them. In 1995, the Hubble space telescope captured its first deep-field image: this showed us that there are hundreds of billions of galaxies in our known universe, huge wheeling collections of stars dispersed through space. Let’s take the International Astronomical Union’s definition of space as everything in the universe apart from our planet and atmosphere. Asking the question “who owns space?” seems laughable. Hubris at a whole new level. The idea that we could lay claim to the rest of the universe is beyond conceit. It’s like a group of atoms in my little toe becoming sentient and declaring that they now own my whole body. A few years ago, I postulated that space exploration could be divided into three distinct eras. The first was confrontation. It was the second world war that fuelled our first forays into the abyss, as this proved to be an effective way of lobbing munitions further. The space race was born from military competition - in a bid to establish superiority. The second era brought collaboration. The formation of the European Space Agency in 1975 and that symbolic docking between Soviet and American space vehicles symbolised what humanity could achieve collectively. But now we’re on the verge of a third era: commercialisation. Space exploration is no longer just the domain of nations, but of billionaires, private companies and start-ups promising holidays in orbit. Of course, the space industry has been commercial for decades - many communications satellites, Earth-observation systems and some launch vehicles are privately funded and operated. But what’s changing is that humans themselves are now part of the business plan, as we move from exploration to possible exploitation. Private space stations, space tourism, lunar and asteroid mining - this is the new frontier. So the question of ownership suddenly has legal, ethical and economic urgency. Legally speaking, the groundwork for managing space was laid long ago. In the late 1950s and early 60s, as rockets first breached Earth’s atmosphere, the United Nations drafted agreements to govern activities beyond our planet. The Outer Space Treaty of 1967 set out some remarkably idealistic principles: “The exploration and use of outer space, including the moon and other celestial bodies, shall be carried out for the benefit and in the interests of all countries, irrespective of their degree of economic or scientific development, and shall be the province of all mankind.” I would reword it to humankind, but I do like the sentiment. It’s a beautiful vision, but potentially an increasingly...
