Here's a picture of the now-famous improvised bolt cleaner that astronauts on the ISS created out of a toothbrush to use during a recent spacewalk. ABC's Gina Sunseri describes the hack:

A $100 billion space station saved by a simple $3 toothbrush? It was the brainstorm of astronauts Sunita Williams and Akihido Hoshide and NASA engineers on the ground: a tool to clean a bolt that gave them so much trouble during a marathon 8-hour spacewalk last week.

They were trying to replace an electrical switching unit, but on Thursday they couldn't bolt it to the outside of the station.

What to do if there is no hardware store in the neighborhood and the next supply ship is months away? Build it yourself -- so they attached a simple toothbrush to a metal pole and voila! They were able to clean out the bolt's socket today and finish the job. Shades of Apollo 13 -- when engineers threw parts on a table and brainstormed a solution, which saved the crew.

Spacewalking Astronauts Fix Space Station With Toothbrush (via Beyond the Beyond)

I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.

    Uh, no. It’s not like the ISS was going to fall out of the sky.

    There I fixed it.

    Its only a bodge if its a half-assed fix.  
    macgyvered yes, bodged no.

    Good find! I’ve been looking for a pic of that tool. Just added this post to my new site homemadetools.net: http://www.homemadetools.net/space-station-bolt-socket-cleaning-tool .

    I bet any old-school cosmonauts who heard about this ingenious fix must be thinking, “If they only knew…”.

      I can’t find a better picture of it, but if you can make it out the tool the cosmonaut is holding is essentially a stick that helps him press buttons in the Soyuz capsule.
      See, the capsule is designed to be piloted by mission control and the panel was built far enough away that the cosmonauts can’t accidentally press anything and so they have to use a stick to do anything.

      that’s right, they invent the finglonger.

    I don’t know if this is true because Adam Curry claims that this would be impossible on the No Agenda show. I mean really,  how could a toothbrush clean something?

  • http://www.beresourceful.net/ Rusty

    Something tells me that by the time the toothbrush was used this way, it had cost a bit more than $3. Getting things into space is still pretty expensive.

    Ah duct tape.. Another glorious win.

    • bcsizemo

      That’s what I was thinking…and if that isn’t going to work then there is a good chance that some form of JB Weld would.

    • Paul Renault

      First:
      This story has gotten way too much press.  I’m a field technician, and I improvise all the time.  In this case, using a toothbrush to clean parts isn’t innovative. For many cases, it’s standard operating procedure.

      The fact that this, to me, oh-so-obvious fix has gotten so much press, and that the astronauts’ idea notion is called a “brainstorm” is a sad testament to just how low we set the bar…

      Second:
      That’s not duct tape.  Duct tape is silver or gray.   

      When it’s green, it’s ‘gun tape’ – tape that’s used to water-seal the bad-guy-facing ends of guns on ships, so that the salt doesn’t corrode the inside of the barrel.  The shells can fire through the tape with removing it first.

      When it’s black, it’s ‘gaffer tape’.  Gaffers are the electricians (and often lighting people) on movie and theatre sets.  They use black tape so it doesn’t reflect light.

      For every other colour, it’s called ‘book-binding tape’.

      • http://twitter.com/incarnedine_v Dan Hibiki

         looks silver to me.

      • ChicagoD

        I like the part where you take a fun story and make it an angry rant. Got a workaround for that?

      • TWX

         Duct, Gaffer, and Book-binding tape all have different adhesive properties, and they make all in multiple colors.  Certainly silver/grey is most common for duct and black most common for gaffer, but if you’re going to be angry and rant, at least be factually correct.

      • GlyphGryph

         And everyone knows that red cars go faster, too!  Because red cars are sports cars, and black cars are SUVs….

        It’s actually been a LONG time since I’ve seen grey/silver ducktape. Red or blue ducktape are the go to colors in these parts.

      • ChickieD

        But these crazy kids who make the beautiful Duct tape prom outfits use so many pretty colors: http://duckbrand.com/Promotions/stuck-at-prom/2012-Top-10.aspx  I guess they are cheating and using bookbinding tape.

    My friend, brother and I tried (and failed) to build an underwater bubble within which we planned to welcome in the New Year 1999. We spent about 100 man-hours underwater on the task. On more than one occasion, we found ourselves on the ocean floor needing a tool that we’d left “up top”. This would result in an aborted dive, a trip back up, a break to off-gas, refilling of tanks, getting the damn tool, etc. We had a saying, “Everything is harder under water.” No doubt this applies many-fold in space. The entire experience left me with a healthy respect for astronauts.

  • Stooge

    It’s good to see they keep a stock of duct tape, but I can’t understand why the ISS doesn’t have a 3D printing rig. Even without throwing a few tens of millions in NASA R&D at it, the current state of the art seems more than capable of justifying its place up there in terms of mass/volume vs usefulness.

    • TWX

      Space exploration rarely adopts new technology quickly.

      On top of that, current 3d printers seem to be gravity-fed, and use small pellets that could be a real PITA to clean up in a microgravity environment if they get loose.

       I don’t blame them for not having a 3d printer yet.  If you read a lot of military SF you’ll find authors including machine shops in their spacecraft when they reach a certain size or mission life cycle, but since we’re not there yet it doesn’t surprise me that we currently lack most semipermanent fab capabilities in space.

      • Stooge

        Turns out I’m wrong and NASA are planning to take their Electron Beam Freeform Fabrication (EBF3)system for a spin on the ISS soon.

    What were dirt and metal particles doing in the bolt hole in the first place? I would think any hole would be scrupulously cleaned before they sent the thing up there.

     See also Neil Armstrong using a ballpoint to prod a circuit breaker in order to get off the moon.
    All future missions should include a bodge box of Polycaprolactone (Polymorph/Friendly plastic), some Sugru, duct tape and super glue.You know, just in case!

    Can we talk about the toothbrush itself? It looks like something they’d give away at a free dental clinic…
