This Is How Metals Are Cold-Welded In Space

Did you know space can fuse metal? @spacetopia.official Cold welding can happen in space, but only when very clean, bare metal surfaces are pressed together in a vacuum. While the ISS is technically in a vacuum, it isn’t a perfect one,low Earth orbit still has traces of atmosphere, atomic oxygen, and other particles that keep surfaces from staying perfectly clean. On top of that, engineers make sure those conditions never exist. Most ISS parts are coated, treated, or lubricated, and the design a
