The arrays feed power into eight electrical circuits, two per wing.
The first two-blanket wing was launched in December 2000 with additional sets delivered in 2006, 20. Each wing is made up of two 39-foot-wide blankets extending 112 feet in opposite directions. The space station is equipped with four huge solar wings, two on each side of the lab's power truss. Finally, congratulations to all of Crew 6 on your 100th day on orbit. "Congratulations to Woody on your first spacewalk and to Steve on your ninth. "I want to say congratulations to the team on an exceptional EVA, you guys were fantastic today," radioed Canadian astronaut Jenni Sidey-Gibbons, the mission control CAPCOM, or communicator. 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. 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. 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. Bowen and Hoburg installed the fifth during Friday's spacewalk and plan to deploy the sixth during another excursion next Thursday.Īs 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. The first four roll-out blankets were installed during spacewalks in 20. 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. Crewmate Bowen, with red stripes around the legs of his spacesuit, is visible at top right. Hoburg, center, holds onto a rolled-up 750-pound iROSA solar blanket while the space station's robot arm carried them both to the installation site at the base of a degraded original-equipment array. EDT, officially kicking off the 264th spacewalk devoted to ISS assembly and maintenance and the seventh so far this year. 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.įloating 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.
