Astronautas mejoran red electrica de la Estacion Espacial

The International Space Station's solar grid received three new lithium-ion batteries during a spacewalk by astronauts Shane Kimbrough and Thomas Pesquet. Assisted by the robot Dexter, they replaced old hydrogen-nickel batteries. NASA plans to replace 48 batteries over the next few years, with new shipments expected from Japan. These batteries store solar energy to power the station during Earth's night side.
