The entire space station is protected
Shipper Orbital ATK is relying on the United Launch Alliance&Light Pink Wool faux fur fabric Atlas V to haul up the goods. 5 on the all-time spacewalking list. Then flight controllers in Houston moved it to a new and better location Sunday. NASA is hoping to take advantage of an extra seat in the Russian Soyuz spacecraft that's due to launch with two astronauts next month and return in September.
That's amazing," Whitson radioed. The spacewalkers hooked up heater cables to the port Thursday. Altogether, she's spent more than 500 days off the planet, also more than any other woman. A shipment with replacement parts needed for that spacewalk is on hold because of rocket concerns at Cape Canaveral, Florida.As Whitson and Kimbrough installed the three remaining shields, Mission Control quickly came up with a TV MacGyver-like plan for a patch.A Russian holds the top spot: Anatoly Solovyev with 16 spacewalks for a grand total of 82 hours. But the getaway items are usually small, like bolts..The 57-year-old Whitson has been in orbit since November. Frustration was evident in Whitson's voice as she told Mission Control about the mishap. Mission Control monitored the shield as it drifted away and, a couple hours later, determined it posed no risk to the 250-mile-high outpost. It was visible in the distance as a white dot. The first flight could occur as early as next year.
It eventually will re-enter the atmosphere and burn up. The astronauts filled the gap using the cover that they had just removed from the relocated docking port. Williams is one of four NASA astronauts who will make the initial test flights of the SpaceX Crew Dragon and Boeing Starliner capsules.It was not immediately clear how the shield got away, said NASA spokesman Dan Huot.The cover is made of the same material as the shielding, according to Mission Control, and just as capable of protecting against potential strikes by bits of space debris and providing thermal control."You guys came up with a fantastic plan — on short notice.
As the drama unfolded, Peggy Whitson set a record for the most spacewalks by a woman — eight — and the most accumulated time spent spacewalking — just over 53 # hours. The lost fabric shield is relatively large: It weighs 18 pounds and, when unfolded, measures about 5 feet by 2 feet and is about 2 inches thick. She was delighted, though, by how well everything turned out. It was disconnected during a spacewalk last Friday by Kimbrough, the space station's commander and a six-time spacewalker. It's supposed to be tethered to the station or spacewalker at all times. Spacewalkers have lost things before, including an entire tool kit in 2008.
The bundled-up shield somehow came loose as Whitson and Shane Kimbrough worked to install micrometeorite protection over a spot left exposed when a new docking port was relocated. The entire space station is protected, in some fashion, against possible debris strikes.Whitson is now No.She's scheduled to return to Earth in June, but may stick around an extra three months, until September. This is her third space station stint.Cape Canaveral: Spacewalking astronauts carried out an impromptu patch job outside the International Space Station on Thursday, after losing a vital piece of cloth shielding when it floated away.NASA, meanwhile, has indefinitely delayed a spacewalk that had been scheduled for next week.The relocated docking port will serve as one of two parking spots for commercial crew capsules under development by SpaceX and Boeing.Midway through the seven-hour excursion, Whitson surpassed the record for women of 50 hours and 40 minutes of total accumulated spacewalking time, held by former station resident Sunita Williams
