The Expedition 33 crew members living and working aboard the International Space Station performed a variety of science experiments and maintenance duties Tuesday. They also participated in conferences with flight controllers to discuss a potential spacewalk and the arrival and departure of the SpaceX Dragon cargo craft.

Commander Suni Williams performed an acoustic survey of the station using a Sound Level Meter, manually filled the Flush Water Tank in the Waste and Hygiene Compartment and performed some maintenance on the Water Processing Assembly.

She also worked with the European Modular Cultivation System, which is a large incubator that serves as a growth chamber for plants aboard the orbiting laboratory.

Flight Engineer Aki Hoshide performed an analysis of water from the Water Processing Assembly and installed Radiation Environment Monitors on five Station Support Computers throughout the station.

He also 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 and Hoshide participated in a conference with flight controllers to review spacewalking procedures for a tentative excursion to repair an ammonia leak in the P6 truss radiator.

They also spoke with flight controllers on the ground during a SpaceX Dragon training debriefing conference. The SpaceX Dragon cargo craft was grappled and berthed to the Earth-facing side of the Harmony module on Oct. 10, delivering 882 pounds of supplies, hardware and science experiments to the orbiting laboratory. It is scheduled to return to Earth when it makes its parachute-assisted splashdown Oct. 28 in the Pacific Ocean, 250 miles off the southern California coast.

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 took a hearing assessment and participated in medical experiments to study the effects of the microgravity environment aboard the station on his health. The station crew members participate in a variety of medical experiments to help experts on the ground develop countermeasures to keep the crew healthy during long-duration spaceflight.

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.

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