06:15 PM EDT, 08/16/13: Cosmonauts return to airlock to conclude marathon spacewalk
Cosmonauts Fyodor Yurchikhin and Alexander Misurkin returned to the safety of the International Space Station's Pirs airlock compartment Friday after a trouble-free spacewalk, setting a new Russian endurance record with a seven-hour 29-minute excursion.
The cosmonauts ran ahead of schedule most of the day, successfully unreeling and routing two long power lines and an ethernet cable along the outside of the Zarya storage module that will be connected to the new Nauka laboratory after its arrival next year.
Misurkin also mounted a space exposure experiment pallet on a handrail outside the upper Poisk module.
The cosmonauts extended a telescoping space crane early on to help move large cable reels from Pirs to Zarya. They originally planned to leave the Strela 1 boom extended, but flight controllers opted to lengthen the spacewalk to give the cosmonauts time to retract it.
The spacewalk began at 10:36 a.m. (GMT-4; time revised by Russian mission control) and ended at 6:05 p.m. when the Pirs airlock hatch was closed.
The seven-hour 29-minute duration set a new Russian spacewalk record, eclipsing the old mark of seven hours and 16 minutes set by two cosmonauts outside the Mir space station in 1990. Two NASA astronauts hold the record for longest spacewalk ever conducted, a marathon eight-hour 56-minute excursion in 2001.
Today's EVA was the 172nd devoted to station assembly and maintenance since construction began in 1998, the sixth so far this year, the seventh for Yurchikhin and the second for Misurkin. Today's EVA pushed Yurchikhin's total time outside to 45 hours and 55 minutes, moving him up to 12th on the list of most experienced spacewalkers.
As it now stands, 112 astronauts and cosmonauts representing nine nations have logged 1,082 hours and 51 minutes of ISS EVA time -- 45.1 days -- building and servicing the space station.
The next major assembly task will be attachment of the Nauka -- "science" -- multi-purpose laboratory module.
The Russians originally planned to launch the MLM aboard a Proton rocket at the end of the year, but officials say the flight is expected to slip several months into the spring of 2014.
During the past several spacewalks, astronauts and cosmonauts have been installing cables and attachment fittings needed to route power and data to and from the new module, which will replace the Pirs airlock and docking compartment.
The Russians eventually plan to launch a multi-hatch node that will be attached to Nauka's Earth-facing end, providing additional ports and the attachment point for a Russian solar power module that will extend to the right side of the space station.
Yurchikhin and Misurkin plan to venture back outside next Thursday to install a telescope mounting platform and to remove docking components from Pirs.
03:00 PM EDT, 08/16/13: Ethernet cable installed
Cosmonauts Fyodor Yurchikhin and Alexander Misurkin have completed installation of an ethernet cable along the side of the Zarya module that will eventually tie a new Russian laboratory module into the station's computer network.
The only major task remaining in the crew's time line is to install the second of two power cables that also will be used by the Nauka lab module. The spacewalkers continue to run ahead of schedule with no technical problems of any significance.
02:15 PM EDT, 08/16/13: First power cable installed
Halfway through a planned six-and-a-half-hour spacewalk outside the International Space Station, cosmonauts Fyodor Yurchikhin and Alexander Misurkin have installed the first of two power cables that will be needed by a new Russian laboratory module.
The spacewalkers now are working to install an ethernet cable before running a second power line the length of the Zarya storage and propulsion module. A space exposure experiment was installed on the Poisk module earlier and overall, the cosmonauts are running about a half hour ahead of schedule.
10:50 AM EDT, 08/16/13: Russian spacewalk 34 begins
Two cosmonauts opened the hatch of the Pirs airlock compartment Friday to kick off a planned six-and-a-half-hour spacewalk outside the International Space Station to install wiring that will be needed by a new Russian laboratory module. They also planned to install a materials science space exposure experiment.
Veteran cosmonaut Fyodor Yurchikhin and Alexander Misurkin opened the hatch at 10:39 a.m. EDT (GMT-4) to officially begin Russian spacewalk 34. For identification Yurchikhin, call sign EV-1, is wearing an Orlan spacesuit with red stripes while Misurkin, EV-2, is wearing a suit with blue markings.
The primary goals of the spacewalk are to install two power lines and an ethernet cable that eventually will be connected to the new Russian laboratory module. The lab, known as Nauka, or "science," will replace the Pirs compartment on the Earth-facing port of the Zvezda command module.
The Russians originally planned to launch the lab module aboard a Proton rocket at the end of the year, but officials say the flight is expected to slip several months into the spring of 2014.
During the past several spacewalks, astronauts and cosmonauts have been installing cables that will route power and data to and from the new module. That work will continue during Russian EVA-34.
First out of the hatch, Misurkin will stand by while Yurchikhin passes out a cable carrier and two sets of power lines, a spool of ethernet cable, gap spanners, cable attachments and the space exposure experiment.
The flight plan calls for Yurchikhin and Misurkin to move around the Pirs module and to attach the reel with the two power cables to the end of the Russian Strela 1 space crane.
Misurkin then will move up Strela 1 to the upper Poisk module, on the opposite side of Zvezda from Pirs, temporarily stowing the science pallet and other gear on a handrail before moving to the crane operator's post.
Misurkin then plans to manually extend the crane, carrying Yurchikhin and the cable reel to the interface between the Zarya module and the U.S. segment of the station.
After tethering the boom, Yurchikhin will retrieve a nearby cradle to secure the Strela 1 more firmly. After removing the safety tether, the cosmonaut will relocate a cable connector installed during a previous spacewalk and attach cable guides on the Zarya module.
Misurkin, meanwhile, plans to mount the space exposure pallet on the side of the Poisk module, to attach two connector patch panels and to install a gap spanner between Poisk and Zarya. At that point, Misurkin will make his way forward to join Yurchikhin on Zarya.
With Yurchikhin feeding power line No. 1 from the cable reel, Misurkin plans to route it down Zarya to Poisk, securing it with the cable guides installed earlier. Once at Poisk, Misurkin will plug cable No. 1 into a patch panel and secure any excess cable to a nearby handrail.
Yurchikhin, meanwhile, will secure any cable remaining on the reel to a Zarya handrail. He then will move down Zarya to Poisk, taking up any slack he finds in the cable.
With cable No. 1 secured, Yurchikhin will route the MLM ethernet cable down Zarya's hull, attaching it to previously installed cable clamps. Misurkin will feed the cable from its reel as Yurchikhin moves down the module, attaching it to a Zarya handrail near the U.S.-Russian interface.
Misurkin will take up any slack in the ethernet cable before Yurchikhin routes power cable No. 2 along Zarya back to the FGB patch panel. After the cable is installed and the slack taken out, the two cosmonauts will head back to Pirs to close out the spacewalk.
This is the 172nd spacewalk devoted to station assembly and maintenance since construction began in 1998, the sixth so far this year, the seventh for Yurchikhin and the second for Misurkin. The cosmonauts plan their third spacewalk together next Thursday.
Going into today's excursion, 112 astronauts and cosmonauts representing nine nations had logged 1,075 hours and 22 minutes of ISS EVA time, or 44.8 days.
