Turning Space Debris into New Spacecraft: The Circular Economy Solution
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Researchers propose transforming space debris into reusable materials for spacecraft through a circular economy approach that reduces waste and creates sustainable systems for future space exploration.
📈 One key stat: 65% of space debris comes from fragmentation events like collisions and explosions, creating a self-reinforcing cycle that poses escalating risks to orbital sustainability.
💬 One key quote: “As space activity accelerates, from mega-constellations of satellites to future lunar and Mars missions, we must make sure exploration doesn’t repeat the mistakes made on Earth,” says senior author and chemical engineer Jin Xuan of the University of Surrey.
1️⃣ The big picture: Space experts warn that current spaceflight practices create unsustainable environmental burdens both on Earth and in orbit. Each rocket launch consumes valuable materials while releasing greenhouse gases and ozone-depleting chemicals into the atmosphere. When satellites and spacecraft reach end-of-life, they’re rarely recycled but instead shifted to graveyard orbits or left as orbital debris. Researchers now propose applying circular economy principles to space activities by designing spacecraft for durability, repair, and recycling. This approach could transform how we manage space resources and reduce the growing problem of space junk.
2️⃣ Why is this good news: A circular space economy applies the familiar reduce, reuse, and recycle principles to satellites and spacecraft design. Space stations could be reimagined as multipurpose hubs supporting refueling, repairs, and manufacturing of new components, decreasing the number of launches required. Technologies like nets or robotic arms could capture and retrieve debris for material recycling while reducing collision risks. Digital tools and AI systems could guide better design choices, reduce waste, and help spacecraft avoid existing debris. This sustainable approach protects both Earth’s resources and the long-term future of space activities.
3️⃣ What’s next: Building a circular space economy requires innovation at every level – from reusable materials and modular spacecraft design to data systems tracking hardware aging in space. International collaboration and new policy frameworks must encourage reuse and recovery beyond Earth. The next phase connects chemistry, design, and governance to make sustainability the default model for space operations.
