Discovery astronauts and their hosts on the International Space Station undocked the Raffaello Multi-Purpose Logistics Module from the Station's Unity Node Friday and reberthed it in the Shuttle's cargo bay.

Discovery Commander Eileen Collins, Pilot Jim Kelly and Mission Specialists Soichi Noguchi (Japan Aerospace Exploration Agency), Steve Robinson, Andy Thomas, Wendy Lawrence and Charlie Camarda, also made preparations for Saturday's undocking of the orbiter. Station crewmembers, Commander Sergei Krikalev and NASA Science Officer John Phillips, helped.

Raffaello is loaded with more than 5,000 pounds of items bound for Earth, including equipment, experiment results and even personal gear of crewmembers dating back to Expedition 6, which left the Station in May 2003. Items for return to Earth have accumulated aboard the orbiting laboratory since the last Shuttle visit in December 2002.

Lawrence and Kelly used the station arm to unberth the module and return it to Discovery. The berthing was completed at 9:03 a.m. CDT. Raffaello, one of three pressurized cargo carrying modules built in Italy for use aboard the Shuttle, brought 3,768 pounds of equipment and supplies to the Station.

After Raffaello was secured in Discovery's cargo bay, Camarda and Thomas used the Shuttle arm to hand off the Orbiter Boom Sensor System to the Station arm. Lawrence and Kelly reberthed the OBSS in its position on the starboard sill of the cargo bay.

After that operation, Lawrence radioed congratulations to those on the ground for the performance of the Canadian-built OBSS and robotic arms. She and Kelly radioed down the Halleluiah Chorus from Handel's Messiah to emphasize those congratulatory words.

Discovery is scheduled to undock from the International Space Station at 2:24 a.m. CDT Saturday. Landing at Kennedy Space Center in Florida is scheduled for 3:46 a.m. CDT Monday.

The next STS-114 mission status report will be issued Saturday morning, or earlier if events warrant.
