NASA Emailed a New Wrench To the ISS

NASA

You know that moment where you overhear a loved one talking about something they really need, and realize you just stumbled onto the perfect thoughtful Christmas present? That’s what just happened on the ISS, where an astronaut recently opined about needing a wrench—and then received one over email and printed it out.

We’ve heard a lot about the ISS’s new 3D printer, which was built and delivered by a California company called Made In Space. Though the printer spit out the first of many test objects back in November, those files were delivered to the ISS on board a cargo supply—not through wireless communication with Earth, as it eventually the goal with the printer.

But that changed this week, when the founder of Made In Space, Mike Chen, was listening to ISS radio communication and heard ISS Commander Barry Wilmore talking about how he needed a wrench. As Chen explains on Backchannel:

We had overheard ISS Commander Barry Wilmore (who goes by "Butch") mention over the radio that he needed one, so we designed one in CAD and sent it up to him faster than a rocket ever could have. This is the first time we’ve ever "emailed" hardware to space.

Because it’s a lot faster to send digital data (which can travel at the speed of light) to space than it is to send physical objects (which involves waiting months to years for a rocket), it makes more sense to 3D-print things in space, when we can, instead of launching them.

So the Made In Space team jumped into Autodesk Inventor, mocked up the wrench, and sent it along to NASA—which transmitted it to the ISS, where Wilmore was able to print the tool out on the 3D printer. It’s pretty incredible to see a technology like this actually making good on some of the most well-worn claims of rapid prototyping—but also pretty cool that an astronaut got a Christmas present. Aww. [Backchannel]
