Adventure in Space: ISS Astronauts Install Fifth Roll-out Solar Blanket to Boost Power (cbsnews.com) 25
The international space station is equpped with four 39-foot blankets (11.8-meters), reports CBS News. The first one was delivered in December of 2000 — and now it's time for some changes:
Two astronauts ventured outside the International Space Station Friday and installed the fifth of six roll-out solar array blankets — iROSAs — needed to offset age-related degradation and micrometeoroid damage to the lab's original solar wings.
Floating in the Quest airlock, veteran Stephen Bowen, making his ninth spacewalk, and crewmate Woody Hoburg, making his first, switched their spacesuits to battery power at 9:25 a.m. EDT, officially kicking off the 264th spacewalk devoted to ISS assembly and maintenance and the seventh so far this year. NASA is in the process of upgrading the ISS's solar power system by adding six iROSAs to the lab's eight existing U.S. arrays. The first four roll-out blankets were installed during spacewalks in 2021 and 2022. Bowen and Hoburg installed the fifth during Friday's spacewalk and plan to deploy the sixth during another excursion next Thursday.
The two new iROSAs were delivered to the space station earlier this week in the unpressurized trunk section of a SpaceX cargo Dragon. The lab's robot arm pulled them out Wednesday and mounted them on the right side of the station's power truss just inboard the starboard wings... As the station sailed 260 miles above the Great Lakes, the 63-foot-long solar array slowly unwound like a window shade to its full length. Well ahead of schedule by that point, the spacewalkers carried out a variety of get-ahead tasks to save time next week when they float back outside to install the second new iROSA.
They returned to the airlock and began re-pressurization procedures at 3:28 p.m., bringing the 6-hour three-minute spacewalk to a close. With nine spacewalks totaling 60 hours and 22 minutes under his belt, Bowen now ranks fifth on the list of the world's most experienced spacewalkers.
"Combined with the 95-kilowatt output of the original eight panels, the station's upgraded system will provide about 215,000 kilowatts of power."
