NASA scientists test Gecko like Grippers in Microgravity

NASA - National Aeronautics and Space AdministrationPasadena, CA – There are no garbage trucks equipped to leave the atmosphere and pick up debris floating around the Earth. But what if we could send a robot to do the job?

Scientists at NASA’s Jet Propulsion Laboratory in Pasadena, California, are working on adhesive gripping tools that could grapple objects such as orbital debris or defunct satellites that would otherwise be hard to handle.

The gecko gripper project was selected for a test flight through the Flight Opportunities Program of NASA’s Space Technology Mission Directorate. As a test, researchers used the grippers in brief periods of weightlessness aboard NASA’s C-9B parabolic flight aircraft in August.

Just as a gecko's foot has tiny adhesive hairs, the JPL devices have small structures that work in similar ways. (Wikimedia Commons)
