This is our first in a series called Terra Nullius. Huh? It’s Latin for ‘Nobody’s Land’. We will be exploring how rules are made for contested territory. If a land belongs to no one, does that mean it’s just up for grabs?

This week we’re starting with outer space, speaking with an expert in space law, Heather Allansdottir. But why should we care about space when the planet we are standing on is falling to shreds?

Currently, outer space belongs to no one. We have an Outer Space Treaty which was developed during the Cold War. But the treaty isn’t durable enough for a second generation of space exploration which includes private actors, not just nation states. Powerful companies, countries and individuals are in a desperate scramble to make it theirs. According Heather, we have about a two-year window to enshrine outer space as a commons, otherwise it will fall to chaos actors and tech billionaires.

In our next Terra Nullius episode, we’ll be talking about governing the skies and the companies that think you want drone-delivered coffee to your backyard.
