(RIA Novosti) - The 13th crew of the International Space Station successfully completed a spacewalk mission Friday, a source at mission control outside Moscow said.
Valery Lyndin said U.S. and Russian astronauts Jeffrey Williams and Pavel Vinogradov had returned to the ISS after installing a new valve on the Zvezda Service Module for the station's Russian-made oxygen-generation system and a new television camera on the American segment of the ISS, reports Trend.
The mission control extended the spacewalk for about an hour at NASA's request, to allow the astronauts additional time to install the camera, an official with Energia Space Corporation said.
The Soyuz TMA-8 spacecraft took the 13th crew and Brazil's first man in space, Marcos Pontes, to the ISS on April 1. Pontes returned to Earth after a short program with the outgoing ISS crew.
