Two Russian cosmonauts spent over six and a half hours outside the International Space Station on Friday installing and retrieving scientific payloads. Pavel Vinogradov and Roman Romanenko performed Friday's EVA, lasting 6 hours and 38 minutes and concluding at 4:41 pm EDT (2041 GMT). The two installed a new set of experiments on the exterior of the ISS and retrieved several others, as well as replacing a retroreflector device used as a navigational aid by European ATV cargo spacecraft. The spacewalk went as planned except for one minor mishap near the end of the EVA, when Vinogradov lost his grip on an experimental panel as he was removing it, causing it to drift away from the station out of reach. The EVA was the first for Romanenko but the seven for Vinogradov who, at age 59, became the oldest spacewalker ever.
