Engineering:Uzlovoy Module
Uzlovoy Module ″Prichal″ also known as UM (Russian: Узловой Модуль ″Причал″, Nodal Module Berth)[1] is a Russian spacecraft which will form part of the International Space Station, and later the proposed Russian OPSEK space station. Approved in 2011 and scheduled for launch on June 2019[2], it is designed to connect modules of the future OPSEK space station.
Design
The nodal module is intended to serve as the only permanent element of OPSEK, a Russian space station intended to support deep space manned exploration missions to Mars, possibly the Moon, and Saturn. Other OPSEK modules will be replaced as they reach the end of their useful life, whilst the Uzlovoy Module will be refurbished on orbit for an extended period.
The module has six hybrid docking ports. One port is equipped with an active docking port to allow docking with the space station, while the remaining five ports are passive, enabling other spacecraft to dock with the module. The Nadir, or earth-facing, port will support automated transfer of propellants between docked Russian spacecraft and the ROS in both directions, and automated docking of manned and unmanned spacecraft using the Kurs system. The docking compartment has an internal volume of 14 cubic metres.[citation needed]
In the current plans the Zvezda nadir location is scheduled to be used by the Nauka module. Additionally the SO2 was put back in the plans, but relocated to Zvezda zenith location (the location for the cancelled SPP).[3]
Uzlovoy Module
In the mid-2000s, RKK Energia, the manufacturer of the ROS components, again added the UM to the future configuration of the ISS. The proposal involves the addition of a Nodal Module (a significant modification of the UDM design, increasing the number of docking ports from 4 to 6 and taking into account its location at the Nauka nadir and at the same reducing its weight from 20 tons to 4 tons, partly by removing the additional life-support system[4]) and adding two additional science/energy modules to the segment around 2013-2015.[5][6] Despite its small size, this four-ton, ball-shaped module could play an extremely important role in the Russian space program.[3]
The preliminary design was completed on 15 January 2011, when RKK Energia announced that its Scientific and Technical Council, NTS, conducted a meeting which reviewed and approved the preliminary design of the Nodal Module and associated hardware. The meeting also approved the specialized launch craft, a Progress cargo ship designated the Progress M-UM and the adaptation of the Soyuz rocket for the launch of the Progress M-UM spacecraft-module.[7][3]
International Space Station
OPSEK is intended to be partially constructed in orbit whilst attached to the ISS. Equipped with six docking ports, the Uzlovoy Module is planned to remain in orbit whilst all other modules come and go as their life span and mission required.[3][7]
The ball-shaped nodal module will support the docking of two scientific and power modules during the final stage of ISS assembly and provide the Russian orbital segment (ROS) additional docking ports to receive Soyuz and Progress spacecraft, as well as additional modules.
Launch
UM was expected to be incorporated into the ISS in 2018.[3] It will be launched along with the Progress M-UM spacecraft; a modified Progress spacecraft which will be used to deliver it to the space station. A Soyuz-2-1b carrier rocket will be used to place it into orbit. Uzlovoy Module will be docked to the nadir, or Earth-facing, port of the Nauka module. However, launch of Nauka was delayed to early 2018.[2] (As of May 2018) launch is planned for June 2019.[2]
