The Progress 10 craft, which arrived at the Station in early February, departed from the aft port of the Zvezda Service Module at 5:48 p.m. CDT (2248 GMT) after hooks holding the Progress to Zvezda had been commanded to unlatch. As the Progress undocked, the ISS was flying 240 statute miles over eastern China. The Progress was filled with items no longer needed on the Station and trash. The Progress will automatically fire its engines later this evening to drop out of orbit and will burn up in the atmosphere.
Aboard the ISS, Expedition 7 NASA ISS Science Officer Ed Lu was asleep at the time of undocking, but ISS Commander Yuri Malenchenko was allowed by flight controllers to remain awake to monitor the autonomous operation.
The departure of Progress 10 sets the stage for tomorrow's scheduled launch of a new Progress resupply ship to the ISS. Progress 12 is due to liftoff from the Baikonur Cosmodrome in Kazakhstan Thursday at 8:48 p.m. CDT (148 GMT Aug. 29). It will dock to the Zvezda aft port on Saturday night at 10:45 p.m. CDT (345 GMT Aug. 31).
The new Progress will carry a half ton of food, fuel, supplies and water for Malenchenko and Lu and science gear for European Space Agency astronaut Pedro Duque of Spain, who is scheduled to launch October 18 from Baikonur on the Soyuz TMA-3 craft with Expedition 8 Commander Mike Foale and Expedition 8 Soyuz Commander and Flight Engineer Alexander Kaleri. Duque will spend eight days aboard the ISS conducting science experiments under a commercial contract between ESA and the Russian Aviation and Space Agency. Duque will return to Earth on Oct. 28 with Malenchenko and Lu.
The new Progress is also filled with personal items and hardware for Foale and Kaleri, who are scheduled to spend almost 200 days aboard the ISS.
Another Progress vehicle currently docked to the Pirs Docking Compartment will undock from the ISS on September 4 to clear the way for the arrival of Foale, Kaleri and Duque in the Soyuz TMA-3 on October 20.
