Aboard the International Space Station, Expedition 30 Commander Dan Burbank worked with the Preliminary Advanced Colloids Experiment-2, or PACE-2, on Monday. Housed in the Fluids Integrated Rack, PACE-2 studies the effects of vibration on particles suspended in fluid in the space environment. This work aids in the development and optimization of crew procedures for the future Advanced Colloids Experiment, also known as ACE.

ACE will fly samples that may have an important impact on our understanding of fundamental physics. An immediate space application for this technology demonstration is in extending the shelf-life of consumables on future long-duration missions.

Burbank also performed routine work with the Total Organic Carbon Analyzer (TOCA), which is necessary for checking drinking water quality. Total Organic Carbon is naturally present in the environment and by itself has no health effects, but it provides a medium for the formation of byproducts that may be harmful.

Flight Engineers Anton Shkaplerov and Anatoly Ivanishin cleaned fan screens and replaced dust filters aboard the outpost. The pair also did regular maintenance on the audio subsystem in the Zvezda service module.

Ivanishin updated antivirus software on one of the station’s laptop computers.

All three crew members spent some time familiarizing themselves with their orbital home.

Three additional Expedition 30 flight engineers – NASA astronaut Don Pettit, Russian cosmonaut Oleg Kononenko and European Space Agency astronaut Andre Kuipers – are scheduled to launch from the Baikonur Cosmodrome in Kazakhstan on Dec. 21.
