On July 27, 2010 Russian cosmonauts Fiodor Yurchikhin and Mikhail Kornienko performed the extra vehicle activities (EVA – space walk).
The cosmonauts installed a new TV-camera which is to monitor ATV rendezvous and docking to the Zvezda module of the Russian segment of the ISS. They also connected the "Rassvet” module’s control and data harness to the "Zarya” module, and laid Kurs system cabling between the 2 modules (Rassvet and Zarya).
The EVA lasted 6 hours and 43 minutes.
