Universal Docking Module
 |
The Universal Docking Module (UDM) (Template:Lang-ru), was a planned Russian docking module for the International Space Station, to be jointly built by RKK Energia and Khrunichev. The Uzlovoy Module addition to the Nauka module, the eventual form of the UDM, grew out of this proposal.
History
The original design resembled the Functional Cargo Block albeit larger, and would have it docked to the nadir (Earth-facing) Zvezda service module docking port, and have four docking ports to accommodate the two Russian Research Modules and the SO2 docking compartment.
Because the SO2 and a Research Module were cancelled due to lack of funds, this module was also cancelled. The one remaining Research Module was then scheduled to be fitted to the open docking port on Zvezda. Later it was also cancelled and that port was allocated to the Docking Cargo Module. DCM scheduled location was later moved to Zarya.
