This essay introduces two concepts for thinking about what earthlings have in common with outer space: terrestrial bias and the nightscape. The aim of these concepts, and this paper, is to explore ways in which shifts in our ordinary language can be used to bring home the importance of protecting the outer space commons, with a particular focus on the orbital commons. This focus on orbital space stems from the fact that it is orbital space that now needs to be protected and managed in light of the booming expansion of the private space industry, and from the fact that our ordinary ways of speaking about space as a common sometimes make us feel as if space is still disconnected from our everyday lives, but only something that will come to matter in some extraterrestrial future. Struggling at once to separate the orbital commons from discourses on space futurism, and to bring the orbital commons down to Earth, this paper aims to suggest new ways of talking about the orbital commons that can help us to see how and why it is already part of our common lives and daily existences, something that we wish to protect not for the future but because it is entangled with forms of life that we already care about, and passionately.
