NASA conducted a spacewalk today to replace the International Space Station’s batteries. Twelve aging nickel-hydrogen batteries will be replaced with six new lithium-ion batteries, a mission that will take two spacewalks. In today’s, astronauts Shane Kimbrough and Peggy Whitson will be at work for six and a half hours.
If you watched the spacewalk, then you saw the astronauts using NASA’s “pistol-grip tool,” a cordless power drill designed for use in space. Built by Swales Aerospace Inc., it is the staple of NASA’s space tool arsenal. The pistol-grip tool helped build the International Space Station as well as the Hubble Space Telescope, and it’s been at all the repairs along the way. Needless to say, NASA’s cordless power drill needs to do a few things that the one in your garage can’t.Fasteners, News
