Mission Overview
Major Mission Goals:

  • Deliver Docking Compartment 1
  • Deliver supplies

    Launch: September 15, 2001 3:35 Moscow time

Docking: September 17, 2001

Mission Details

The Docking Compartment 1 is a small module delivered by a Progress spacecraft propulsion module called Progress M-CO1. Its purpose is to provide an airlock for the Russian side of the station. Previously, in order to exit the Russian segment required shutting off the Service Module forward docking node which is inconvienent to station operations.
The Docking Compartment 1 also provides a platform for a Strela EVA crane, and a docking port for Soyuz spacecraft which allows a Progress to remain docked to the aft Service Module port while a new Soyuz docks to either the Docking Compartment 1 or FGB docking port, while an old Soyuz remains docked to the other port.
In October, two EVA's were carried out to fully activate the Docking Compartment. This included installing the Strela crane, docking target, and disconnecting the old Service Module Kurs automated docking system and reconnecting it to the Docking Compartment's Kurs antenna's.
The Docking Compartment's airlock facilities allow for support and servicing of 2 Orlan space suits (no US EMU compatiblity).
The module was named Pirs, Russian for Pier. One end of the module is designed to dock to the Service Modules hybrid docking assembly while the other end is a standard Drouge port for Soyuz/Progress dockings. A hatch on the side, or the docking Drouge can be used for EVA.

Cargo

The propulsion section carried 870 kg of propellant. The module itself carried about 800 kg of cargo, including 290 kg module equipment (cargo boom, external worksite, portable universal container); 285 kg including spacesuit Orlan-M, life support system equipment; 65 kg of hardware for
performance of space experiments and research Plasma Crystal-3, GTS, and the Andromeda Project Experiment program Russian-French flight to be performed in October during the ISS visiting crew mission; 130 kg, flight data files, sanitary-hygienic and water support systems, and crew health care equipment.
After docking, and before the propulsion module jettisoned, the ISS massed 140.5 tons including Progress M-45, Soyuz-TM-32, Progress M-CO1, Russian Service Module Zvezda, Functional Cargo Module Zarya, U.S. modules Node-1 Unity, US Lab Destiny, Airlock Quest, the P6 truss, Z1 truss, and PMA's 1, 2 & 3 and other minor components.

Future

    The Docking Compartment 1 is planned to have a limited lifetime. It is planned to eventually replace it with a larger module with multiple docking ports to accomidate more modules. At various times in the station project this module has been planned to be the Universal Docking Module, the backup FGB-2. When this module is ready, the Docking Compartment 1 will be jettisoned, unusable due the unique Service Module docking mechanism. Another, Docking Compartment 2 would replace it attached to the new module.
