On Wednesday, NASA emailed the design of a socket wrench to astronauts so that they could print it out in the orbit. According to Made In Space, this is the first tool to be designed on the ground, sent into orbit, printed and used successfully in zero gravity at ISS. This tool was especially designed on-demand, and it does exactly the kind of work that its designers had hoped it would do.
Made In Space co-founder Mike Chen wrote on his blog on Medium, “The socket wrench we just manufactured is the first object we designed on the ground and sent digitally to space, on the fly. This is the first time we've ever 'emailed' hardware to space”.
