Space Station Gets Powerful Boost
Powering the International Space Station (ISS) 24/7, 365 is a challenge — even for the nation’s top scientists at NASA. One unique aspect of this challenge is providing power to the station when solar energy is not an option — that job is left to the space station’s powerful batteries.
NASA astronauts just completed a six and a half hour spacewalk in order to replace the space station’s existing batteries and provide the ISS with a major upgrade. The batteries aboard the ISS are crucial for providing power to the space station when orbital darkness prevents sunlight from reaching the solar cells. |

NASA astronauts installed modern, cutting-edge Lithium-Ion (Li-Ion) batteries to replace the aging Ni-H2 batteries that previously powered the space station. Li-Ion batteries are much lighter and smaller than the Ni-H2 batteries they are replacing and will serve as an immediate upgrade for the ISS.
One Li-Ion battery is as powerful as two Ni-H2 batteries – this means half the number of total batteries are needed to power the ISS and the missions needed to replace the batteries will be cut in half.
