Filled with 2.5 tons of food, fuel and supplies for the station's Expedition 13 crew, the ISS Progress 22 automatically docked to the Pirs airlock at 11:25 a.m. CDT as the spacecraft and the station sailed 220 miles above northern Africa. The 22nd Progress to visit the station was launched Saturday from the Baikonur Cosmodrome in Kazakhstan.
Commander Pavel Vinogradov and Flight Engineer Jeff Williams will open the hatch to the supply ship once leak checks are completed later Monday. The crew will begin unloading items Tuesday.
The supplies include food, fuel, oxygen and air, clothing, experiment hardware and spare parts, as well as personal items from the crew's families. The new Progress joins an older Progress supply ship that arrived at the stationís Zvezda Service Module in April. Progress 21 will remain docked until mid-September. It will be used to stow trash, and its supply of oxygen will help replenish the stationís atmosphere when required.
ISS Progress 22 holds 1,918 pounds of propellant for the Russian thrusters, 108 pounds of oxygen and air as a backup supply for the oxygen generated by the Russian Elektron system and 264 pounds of water to augment onboard supplies. The new cargo also includes 2,800 pounds of spare parts, experiment hardware and life support components.
The experiment hardware includes items that will be used by European Space Agency astronaut Thomas Reiter once he arrives via the Space Shuttle Discovery's STS-121 mission. This flight will return the station to three crew members for the first time since 2003.
