Space debris poses a significant threat to operational satellites and the International Space Station, with millions of fragments orbiting Earth at high velocities. To address this challenge, researchers have proposed the concept of a "laser broom," a ground-based laser beam-powered system designed to clear space debris. By directing powerful laser beams at debris, the system heats one side of the object, causing it to shift its orbit and re-enter Earth's atmosphere, where it burns up upon re-entry. This method aims to mitigate the risk of collisions and reduce the accumulation of space junk. en.wikipedia.org
The laser broom concept offers several advantages, including the ability to target multiple debris objects simultaneously and the potential for rapid deployment. However, challenges remain in terms of precision targeting, energy requirements, and ensuring the safety of operational satellites during the debris removal process. Ongoing research and technological advancements are focused on addressing these challenges to make laser brooms a viable solution for space debris mitigation. en.wikipedia.org
