Hey edkyle99Perhaps I expressed myself wrong.These (very intresting) missions launch (and unfurl) a solar sail.What I'm asking is, if ever there has been a mission that made the sail in space. Meaning the stuff that is actualy launched is something closer to a stock rod of aluminized Mylar then a sail. So not the actual sail but the materials to make a sail.Perhaps a device capable to thermally evaporated a thin films of aluminin (AKA a solar sail)Still thank you for your comment
There has never been a mission involving manufacturing a solar sail in space. While watching the National Geographic documentary Destination Space, I happened to see computer generated imagery of a NASA design study for a giant solar sail measuring half a mile wide, and it's unclear whether a gigantic solar sail would need to be assembled in space or on earth.
