Russian Cargo Ship Departs the ISS

Three months after delivering 2 1/2 tons of food, fuel and supplies for the Expedition 40 crew, the unpiloted Russian ISS Progress 55 cargo ship undocked from the International Space Station July 21. Loaded with trash, the Progress was maneuvered by Russian flight controllers to a safe distance away from the station for 10 days of engineering tests. It will be deorbited on July 31 so it can burn up in the Earth's atmosphere over the Pacific Ocean. The crew is expecting the arrival of a new Progress craft on July 23 loaded with fresh supplies.
