(NASA) – Aboard the International Space Station, the Expedition 20 crew worked Tuesday on maintenance of an oxygen generating system and continued preparations for the arrival of space shuttle Discovery and a new crew member.

Discovery, targeted to launch Aug. 25 on the STS-128 mission, is carrying more than seven tons of supplies, science racks and equipment, as well as additional environmental hardware to sustain six crew members on the orbital outpost. The shuttle will also deliver the newest Expedition crew member, astronaut Nicole Stott, for a three-month stay aboard the station.

Flight Engineer Tim Kopra, who will be returning to Earth aboard Discovery, performed additional inspections of the tools and tethers that the STS-128 astronauts will use during their three planned spacewalks.

Supporting spacewalk preparations, Flight Engineer Mike Barratt conducted a session of onboard training for Simplified Aid for EVA Rescue, or SAFER. Should a spacewalker become untethered during a spacewalk and begin floating away, the small nitrogen-jet thrusters of SAFER could propel the astronaut back to the station.

In the U.S. segment of the station, flight engineers Bob Thirsk and Frank De Winne removed and replaced a filter on the Oxygen Generation System, which was shut down on Aug. 10 when its assembly pump exhibited an unusual rise in pressure. Since the complementary Russian Elektron oxygen generating system will not be reactivated until Friday, the station’s atmosphere is being replenished currently with supplies from the docked Progress cargo craft and from the ignition of solid fuel oxygen generator “candles” nearing the end of their shelf life.

Meanwhile, Commander Gennady Padalka wrapped up some work on the onboard telemetry measurement system in the Zvezda service module. Flight Engineer Roman Romanenko conducted a session with an experiment designed to measure radiation dynamics in the station’s environment.

The crew had time set aside Tuesday for Earth observation and photography, including several opportunities to acquire still photos and videos of Hurricane Bill as it churns through the Atlantic.
