Scientists are copying geckos' unique skills in the mission to clean up space junk.
Experts reckon there are 500,000 bits of space rubbish floating around the earth.
Most of them are man-made bits of metal left over from satellites, rockets and other space missions.
They're going at 17,000 miles per hour and are a danger to other satellites and even to the space station!
And leaving junk up there isn't exactly environmentally friendly.
So how can geckos help?
Well, the lizardy reptiles have a special sticky grip which experts hope could be used to grab metal floating around the Earth.
