Crew members on the International Space Station (ISS) repaired a faulty oxygen generator that earlier had leaked fumes inside the ISS.

Expedition 14 Flight Engineer Mikhail Tyurin installed new valves and cables to repair the Elektron oxygen-generation unit which shut down in mid-September. Tyurin re-activated it after installing the new parts, and the Elektron is supplying oxygen for the cabin atmosphere.

The crew also began gathering tools for a Nov. 22 spacewalk. Spacewalkers will replace and retrieve several science experiments from the hull of the Zvezda Service Module.

Tyurin also plans to hit a golf ball from a bracket on Pirs as part of a Russian commercial activity.
