A few years ago, there was a panic about lithium-ion batteries that exploded and could do things like take down a jetliner. On a recent trip, an airline asked passengers to turn in any devices with batteries that had been banned because of safety concerns. These are indicators of a widely understood downside of lithium-ion batteries, ubiquitous in cell phones, laptops, and other electronic hardware—they can easily catch fire very spectacularly. However, a team at the Aerospace Company is working on an idea to turn this potentially catastrophic event into an asset—by using it to deorbit defunct satellites.
Could puncturing a satellite’s battery help it deorbit faster?
