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.
