Two astronauts stepped outside the International Space Station (ISS) on Friday, Jan. 13, to perform a 6-hour spacewalk for changing aging batteries for the power grid of the laboratory. The recent upgrade will boost and keep the ISS running into the next years, according to NASA.
The nearly 6 and a half hour spacewalk was collectively carried out by U.S. astronaut Shane Kimbrough and French astronaut Thomas Pesquet. By the way, this was the fourth spacewalk of Kimbrough's profession and the first one for Pesquet. The duo left the ISS' airlock at around 6:30 a.m. EST to perform the job of changing the batteries and total many other maintenance tasks prior to going back inside the space laboratory just before 12:30 p.m. EST.The astronauts continued the work began during a spacewalk earlier in January to fit an array of 428-pound lithium-ion battery packs to the ISS' solar power system. "The new lithium-ion batteries and adapter plates change the nickel-hydrogen batteries presently used on the station to keep electrical energy produced by the station's solar arrays," NASA mentioned."These new batteries offer an improved power capability for operations with a lighter mass and a smaller volume than the nickel-hydrogen batteries."
The first six of the brand-new 24 lithium-ion batteries were transported to the spaceport station in December aboard a Japanese HTV cargo ship. The remaining 18 brand-new lithium-ion battery packs will be taken to the ISS through Japanese resupply missions in the future.
According to the United States National Aeronautics and Space Administration, it will take three more years to complete the flying area laboratory's power system upgrade that will keep it practical till at least 2024. The ISS is solar energy and draws power from its batteries while flying through darkness. The International Spaceport station is a $100 billion research study lab that is owned and operated by 16 nations and is as big as a five-bedroom house, based on a science news.
