On August 10, 2015 at 14:17 UTC two Russian cosmonauts Gennadiy Padalka and Mikhail Kornienko began their spacewalk. The cosmonauts had 10 objectives, including installation of padded handrails to make future EVAs easier; installation of fasteners to hold antenna covers in place; the replacement of one antenna; inspections of external experiments and the retrieval of a plasma physics experiment package. They also cleaned one of Zvezda’s windows to remove residue deposited by thruster firings and collected similar residue samples from a solar array panel and the area around vents used by a Russian oxygen generator and carbon dioxide scrubber. There were no problems of any significance and the spacewalkers ran ahead of schedule most of the day. The cosmonauts spent 5 hours and 34 minutes outside the International Space Station. This was the 188th spacewalk devoted to station assembly and maintenance since construction began in 1998. It was also the 48^th spacewalk performed from the Russian segment of the ISS. It was the 10^th EVA for Gennadiy Padalka and the 2^nd EVA for Mikhail Kornienko.
