I’ve always felt a sense of stewardship toward this place we know as our home, Earth. That feeling came to fruition most intensely while on a trip to Alaska in 2015, when I saw the way certain indigenous groups live in harmony with our planet despite the terrible environmental and societal damage caused by colonization. I thought: ‘We, as humanity, will not survive if we do not embrace stewardship over ownership.’
Ownership asks us to make claims to rights, whereas stewardship asks us to make claims to responsibilities. The effect on the environment, and our ability to use it harmoniously and sustainably, is determined by whether we adopt an ethos of ownership or of stewardship.
As an astrodynamicist, who studies the motion of natural and human-made bodies in space, I knew space was a neglected ecosystem that needed to be protected. If this next frontier is full of junk, we won’t be able to fully explore or tap into the innovations that space can provide. That will jeopardize our ability to reliably know more about ourselves and our planet — knowledge that stems uniquely from space-based data.
Armed with this knowledge, and inspired by indigenous traditions of environmental stewardship, I became — what I like to call — a space environmentalist.
Creating empathy for space
So how do we solve this growing concern of space debris and not repeat the same mistakes we’ve made on Earth? How can you become a space environmentalist too?
For an average citizen, being part of the solution can feel overwhelming — but we all have a role to play. It begins with taking note of what’s happening, spreading awareness and learning more about how interconnected everything actually is. Everyone needs to understand that what we do in one location on Earth influences our oceans, our air and yes, space. And we need to act accordingly.
I co-founded and serve as chief scientist at Privateer, a company which supports these efforts by developing proprietary tools to monitor human-made objects in space. We aim to show people the evidence of this interconnectedness so that they are more reluctant to say, “that’s not my problem,” and we want to guarantee a safe and accessible future for humanity’s space resources.
Ultimately, space sustainability is more than just tracking satellites and debris accurately. It’s vital that these data are used to support the responsible and harmonious use of space. We must find ways to share space between private companies, government agencies and academia across nations, generations and cultures.
Space is a global commons. It belongs to no one.
At the end of the day, we all need to become space environmentalists.
