The UM (Uzlovoy Module) or NM (Node Module) is a node to be added to the Russian part of the ISS complex. It is also named Prichal. UM will be delivered by a modified Progress space tug, called Progress-M-UM. The UM will be docked to the nadir port of the MLM (Nauka) module, providing four ports to mount additional modules and one docking port for cargo and crew spacecrafts.
The International Space Station programme is tied together by a complex set of legal, political and financial agreements between the sixteen nations involved in the project, governing ownership of the various components, rights to crewing and utilization, and responsibilities for crew rotation and resupply of the International Space Station. It was conceived in 1984 by President Ronald Reagan, during the Space Station Freedom project as it was originally called.
The modified Progress space tug called Progress-M-UM will dock the Prichal node module to the nadir port of the MLM Nauka module on the International Space Station. It will provide four ports to mount additional modules and one docking port for cargo and crew spacecrafts.
Roscosmos cosmonauts Anton Shkaplerov and Pyotr Dubrov will exit the International Space Station through the Poisk airlock to establish external cable connections between the MLM Nauka module and the UM Prichal module.
