RENEE MONTAGNE, HOST:
Good morning. I'm Renee Montagne with a story of a stellar MacGyvering. The International Space Station was faced with a malfunctioning electrical unit and couldn't screw down a new one because the exterior bolts were covered in debris. After two astronauts were stuck outside for hours, they hit on an idea - scrub the bolts clean with a toothbrush. It was a thrifty fix for the $100 billion space station and luckily the toothbrush was a spare. It's MORNING EDITION. Transcript provided by NPR, Copyright NPR.
