A busy week of science, maintenance and preparations aboard the International Space Station kicked off Monday with a reboost of the orbital complex.

On Monday afternoon, the Zvezda Service Module's engines were fired to raise the space station to the correct altitude for the upcoming Soyuz TMA-11 and Space Shuttle Discovery dockings in October.

Earlier Monday, Flight Engineer Clay Anderson conducted a ham radio session with students at the Heidelberg University for Applied Sciences in Heidelberg, Germany.

Over the weekend, Anderson conducted a "Saturday Science" session with the Analyzing Interferometer for Ambient Air (ANITA) payload. Developed by the European Space Agency, ANITA determines concentrations of up to 32 different trace gases in the station's atmosphere.

With the Progress 25 undocking on Sept. 18, the aft port of the Zvezda service module is open and ready for the relocation of the Soyuz TMA-10 on Thursday. The relocation opens up the Zarya nadir, or earth-facing, port for the arrival of Expedition 16 in its Soyuz TMA-11 on Oct. 12.
