Scientists have discovered tiny carbon nanotubes that are incredibly strong and conductive. These nanotubes could be used to make lighter and stronger materials for spacecraft. The researchers are trying different methods to make these nanotubes in large quantities, like using lasers or chemical reactions. So far, the laser method makes the cleanest nanotubes, but not a lot of them. The arc method makes more nanotubes, but they are not as pure. The chemical method is still being tested, but it looks promising. The researchers are also working on ways to clean and purify the nanotubes. These nanotubes could be used in many different things like electronics, batteries, and lightweight materials.
