        How Would You Turn a Bolt in Space?

        Tools such as saws, hammers, and levers are designed to make work easier. Sometimes, the environment in which a person works dictates whether or not a certain tool will get the job done. In the microgravity environment of space, astronauts are often required to do experiments or simple repairs. On Earth, gravity helps anchor a person to the ground, making tightening a bolt a rather simple activity. In this video segment from NASA Brain Bites™, learn why engineers have had to develop different types of bracing systems—a whole new set of tools—to assist astronauts working in space.

        This video is available in both English and Spanish audio, along with corresponding closed captions.
