Even entire derelict satellites are drifting through space, having long fulfilled their purpose. In fact, an astonishing [60 percent of our planet's roughly 6,000 satellites]() are no longer in operation. That's a problem, as any collision could end in disaster — or the dreaded knock-on effect known as Kessler syndrome, a cascade of collisions generating new pieces of dangerous space debris that could render Earth's orbit uninhabitable. That's why Russian physicist Egor Loktionov is suggesting a highly unusual intervention: using space-based lasers to melt non-operational satellites into plasma, the [*Academic Times* reports](). ## Zap! Zap! As detailed in [a paper]() soon to be published in the journal *Acta Astronautica*, Loktionov has been testing several different spacecraft materials and how they react to pulses of laser emissions. "Many ways to capture debris have been suggested to date, few are tested and none really practiced," Loktionov told *The Academic Times*. "Laser space debris removal, to my mind, should provide a cheaper, more reliable and flexible way to do the job." ## Space Clean Up "If shot from space, lasers would pose close to zero hazards," Loktionov told the *Academic Times*. "We suggest considering more precise impacts with space-borne lasers or our recycling concept." The concept, as [Loktionov suggested in research published 2019](), would reuse space debris in the form of melted plasma as fuel for laser thruster-powered spacecraft. The proposal is as relevant as ever because our space debris problem is about to get a lot worse with the likes of SpaceX and Amazon planning to launch extensive constellations of broadband internet-beaming satellites. That means no stone should be left unturned in the quest to find a way to make a dent in our growing space junk problem — no matter how far out the concept. **READ MORE:** [Orbital lasers could melt defunct satellites without polluting space]() \[*The Academic Times*\] **More on space debris:** *[Europe Is Launching a Giant Claw to Grab Space Junk]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
