The station's 24th Progress unpiloted cargo carrier will bring to the orbiting laboratory more than 1,720 pounds of propellant, about 110 pounds of oxygen, and 3,285 pounds of dry cargo – a total of 5,115 pounds.

P24 will launch from the Baikonur Cosmodrome in Kazakhstan. It is scheduled to reach the station after a flight of just over two days. Docking is to be on Friday, Jan. 19 a little after 10 p.m.

The spacecraft will use the automated Kurs system to dock at the Pirs Docking Compartment. Expedition 14 flight engineer Mikhail Tyurin will stand by at the manual Toru docking system controls, should his intervention become necessary.

Expedition 14 crew members, Commander Mike Lopez-Alegria, Tyurin and Flight Engineer Sunita Williams, finished filling P24's sister cargo carrier, ISS Progress 22, with trash and other discards for its Jan. 16 undocking from Pirs and subsequent destruction on re-entry.

After its unloading, P22 was used as a storage area for a while. Many items brought to the station aboard the space shuttle Discovery on STS-121 in July eventually found a temporary home there until crew members could put them in more permanent places.

ISS Progress 23 remains at the aft compartment of the Zvezda Service Module. It is scheduled to undock in April.

The Progress is similar in appearance and some design elements to the Soyuz spacecraft, which brings crew members to the station, serves as a lifeboat while they are there and returns them to Earth. The aft module, the instrumentation and propulsion module, is nearly identical.

But the second of the three Progress sections is a refueling module, and the third, uppermost as the Progress sits on the launch pad, is a cargo module. On the Soyuz, the descent module, where the crew is seated on launch and which returns them to Earth, is the middle module and the third is called the orbital module.
