The combined Endeavour and International Space Station crews are now down to nine following the first Soyuz departure in history while a shuttle was docked to the station.

Following the 4:35 p.m. CDT departure on Monday, an unprecedented photo session from the Soyuz documented the 1 million pound complex while the shuttle remained docked, and the station was commanded to slowly rotate for the photographer.

The Expedition 27 crew members undocked their Soyuz about two hours after Endeavour's astronauts' sleep period had begun. Endeavour's crew had most of the day off.

The Endeavour crew, and now Expedition 28 flight engineer Ron Garan, were awakened at 7:26 p.m. to the song "Svegliarsi La Mattina (Woke Up This Morning)" by the Italian duo Zero Assoluto, uplinked especially for mission specialist Roberto Vittori of Italy.

STS-134 commander Mark Kelly, pilot Greg "Box" Johnson and mission specialists Andrew Feustel and Mike Fincke and Greg Chamitoff will lend their hands to maintenance tasks around the station, installing a new filter inside the Oxygen Generation System to provide continuous carbon dioxide scrubbing whenever the system's recirculation loop is running.

Spacewalkers Fincke and Feustel will review procedures for the STS-134 mission's third spacewalk, scheduled for Wednesday, together with this spacewalk's choreographer Chamitoff. Fincke and Feustel will prepare for the first use of the In-Suit Light Exercise.

Crew members will also take part in two media interviews, the first with San Francisco and Sacramento reporters, and the second with Pittsburgh and Houston reporters.
