These #solar arrays on the International #Space Station are the reason #human inhabitants can enjoy #electricity hundreds of miles above the #Earth. The 262,400 solar #cells that comprise the station’s four sets of arrays make 84 to 120 kilowatts of electricity—that's enough electricity to #power more than 40 homes. When the space station is on its way into space, the solar arrays are folded like an accordion. They are spread out when the station is in #orbit. #photooftheday #ISS #NASA #electric #science #tv #internet 📷 @nasa
