The crewmembers were inside Zvezda monitoring the automated docking as ISS flew 220 statute miles above Central Asia near northern Kazakhstan at the time of contact and capture. Once leak checks are completed, Krikalev and Phillips will open the hatch to Progress later today and will begin to unload its contents on Sunday.
The supplies include food, fuel, oxygen and air, clothing, experiment hardware, and Russian spacesuit components. The more than 2,700 pounds of dry cargo contained in this supply ship also include a new water circulation device called a liquids unit for the Station's Elektron, the primary system for supplying oxygen for the crew to breathe and spare parts for the Vozdukh carbon dioxide removal system. Time is set aside in the crew's schedule Sept. 15 for installation of the new liquids unit to attempt to bring Elektron back into service, months after it failed.
The remainder of the Progress payload includes 1,763 pounds of propellant for the Russian thrusters, 242 pounds of oxygen and air in tanks as a backup supply for the oxygen generated by Elektron and 463 pounds of water to augment the supplies left by The Space Shuttle Discovery during the recent STS-114 mission.
Some of the clothing and personal effects delivered to the Station today include items for the next resident crew of the Station, Expedition 12 Commander and NASA Science Officer Bill McArthur and Flight Engineer Valery Tokarev. They are scheduled to launch from the Baikonur Cosmodrome in Kazakhstan Oct. 1 on the Soyuz TMA-7 capsule.
