Astronauts Float Outside ISS to Upgrade Batteries to Lithium-Ion in Spacewalk


On the International Space Station, Expedition 50 commander Shane Kimbrough and Flight Engineer Peggy Whitson of NASA floated outside the Quest airlock for a 6 hour 32 minute spacewalk to complete half the work involved with upgrading the ISS’s power supply.

The ISS uses Nickel-Hydrogen batteries and over a complex project will be replaced with modern Lithium-Ion batteries.

Another spacewalk will take place next Friday, January 13th with NASA astronaut Shane Kimbrough and ESA astronaut Thomas Pesquet.
