2 cosmonauts set new Russian spacewalk endurance record.
On August 16 Russian cosmonauts Fjodor Yurchikhin and Alexander Misurkin performed a spacewalk. The spacewalk began at 14:36 UTC when the cosmonauts opened the hatch of the Russian "Pirs” module of the International Space Station. The cosmonauts extended a telescoping space crane to help move large cable reels from "Pirs” to "Zarya”. The cosmonauts unreeled and routed two long power lines and an ethernet cable along the outside of the Russian "Zarya” module that will be connected to the new Russian "Nauka” module after its arrival next year. Misurkin also mounted a space exposure experiment pallet on a handrail outside the Russian ”Poisk” module. The spacewalk lasted 7 hours and 28 minutes. The hatch of the Russian "Pirs” module was closed at 22:05 UTC. 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 July 1990. Two NASA astronauts hold the record for longest spacewalk ever conducted, a marathon eight-hour 56-minute excursion in 2001.
