Even in the highest of high-tech operations, sometimes it's the simple tool that does the trick.

Astronauts aboard the International Space Station put an ordinary toothbrush to work to solve a problem with a troublesome bolt on the exterior of the satellite, ABC News reported.

Sunita Williams and Akihido Hoshide were struggling to replace the electrical switching unit on the station's eight-panel solar array systems during an "epic, eight-hour spacewalk." The astronauts were unable to tighten a bolt to secure the unit, forcing them to improvise.

Williams and Hoshide suspected the bolt holes may have been filled with metal shavings, preventing them from tightening, so the astronauts strapped the 220-pound unit down using temporary straps and cast around for a solution.

Using the most ordinary of household items, the astronauts attached a toothbrush to a metal pole and went out for a second space walk. Using a combination of the brush and compressed nitrogen, they were able to clear out the obstruction.

Not only did a little bit of ingenuity save the crew extra work, but the the repair time pushed Williams over the previous record-holder to become the woman with the most time spent on a spacewalk.

The Curiosity robot is equipped with a nuclear-powered lab capable of vaporizing rocks and ingesting soil, measuring habitability, and potentially paving the way for human exploration, and was designed to assess whether Mars ever had an environment able to support small life forms called microbes.
