The Expedition 33 crew members living and working aboard the International Space Station made preparations for an upcoming spacewalk and worked with a variety of science experiments Wednesday.

Commander Suni Williams and Flight Engineer Aki Hoshide reviewed procedures with flight control teams and prepared equipment in the Quest airlock for an upcoming spacewalk. During the excursion, Williams and Hoshide will venture out of the Quest airlock on to the exterior of the station to repair an ammonia leak in the P6 truss radiator.

Hoshide worked with the Microbe-III experiment, which monitors the abundance and diversity of fungi and bacteria in the Kibo module. The results will be used to produce a microbiologically safe environment which is essential for a long-time stay in space.

Williams performed some maintenance work on an Iodinated Contingency Water Container, removing gas and transferring water from the container to the Water Processing Assembly storage tank. She also calibrated the oxygen sensor of the Compound Specific Analyzer.

In addition to her maintenance work, Williams deactivated the mixing tubes in the NanoRacks Module 9 payload. NanoRacks provide microgravity research facilities for small standardized payloads aboard the station.

Flight Engineer Yuri Malenchenko worked in the Russian segment of the station, monitoring its systems and performing a variety of housekeeping and maintenance duties.

He also worked with an experiment known as Relaxation, which examines chemical luminescent reactions from jet engine exhaust in the Earth’s atmosphere.

The Zvezda service module fired its engines on Wednesday at 11:24 a.m. EDT during a 19-second reboost. The orbit adjustment places the station in a higher orbit to accommodate the upcoming launch of the Soyuz TMA-06M spacecraft on Oct. 23, as well as the launch of the ISS Progress 49 cargo craft on Oct. 31.

Meanwhile, three additional Expedition 33 flight engineers continue launch preparations at the Baikonur Cosmodrome in Kazakhstan. NASA astronaut Kevin Ford, and Russian cosmonauts Oleg Novitskiy and Evgeny Tarelkin, are set to launch aboard their Soyuz TMA-06M spacecraft on Oct. 23 for a five-month mission on the station.
