Scientists have designed a lightweight aluminum material inspired by eggshells that could one day help protect spacecraft from fast-moving pieces of space debris. Nearly one million pieces of debris larger than 1 centimeter are believed to be orbiting near Earth. These fragments can travel at extremely high speeds, so even a relatively small object can […] The post Eggshell-Inspired Aluminum Shield Could Protect Spacecraft from High-Speed Debris appeared first on Knowridge Science Report .
