Universal Docking Module
The Universal Docking Module (UDM) (russian: Универсальный стыковочный модуль), was a planned Russian docking module for the International Space Station, to be jointly built by RKK Energia and Khrunichev. The ''Prichal'' nodal addition to the ''Nauka'' laboratory, the eventual form of the FGB-2 design upon which the UDM was based, grew out of this proposal. History The original design resembled ''Zarya'' but was larger. It would be 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, later named '' Poisk''. Because one Russian Research Module was 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 and Cargo Module, later named ...

International Space Station
The International Space Station (ISS) is the largest modular space station currently in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). The ownership and use of the space station is established by intergovernmental treaties and agreements. The station serves as a microgravity and space environment research laboratory in which scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. The ISS is suited for testing the spacecraft systems and equipment required for possible future long-duration missions to the Moon and Mars. The ISS programme evolved from the Space Station ''Freedom'', a 1984 American proposal to construct a permanently crewed Earth-orbiting station, and the contemporaneous Soviet/Russian '' Mir-2'' proposal from 1976 with similar aims. The ISS is the ninth space station to ...

Nauka (ISS Module)
''Nauka'' ( rus, Наука, p=nɐˈukə, litt. ''Science''), also known as the Multipurpose Laboratory Module-Upgrade (MLM-U; Russian: Многоцелевой лабораторный модуль, усоверше́нствованный, or ''МЛМ-У'') or simply Multipurpose Laboratory Module (MLM), is a module of the International Space Station (ISS). The MLM-U is funded by Roscosmos. In the original ISS plans, ''Nauka'' was to use the location of the Docking and Storage Module (DSM). Later, the DSM was replaced by the '' Rassvet'' module and ''Nauka'' was moved from '' Zarya''s nadir port to ''Zvezda''s nadir port. The launch of ''Nauka'', initially planned for 2007, was repeatedly delayed. By May 2020, ''Nauka'' was reported to be planned for launch in the second quarter of 2021, after which the manufacturer's warranties of some of ''Nauka''s components, such as engines, would have expired. ''Nauka'' was finally launched on 21 July 2021, 14:58 UTC, along with the ...

Zarya (ISS Module)
''Zarya'' (russian: Заря, , Dawn), also known as the Functional Cargo Block or FGB (from the russian: "Функционально-грузовой блок", , ''Funktsionalno-gruzovoy blok'' or ''ФГБ''), is the first module of the International Space Station to have been launched.NASA, International Space StationZarya(accessed 19 Apr. 2014) The FGB provided electrical power, storage, propulsion, and guidance to the ISS during the initial stage of assembly. With the launch and assembly in orbit of other modules with more specialized functionality, it is primarily used for storage, both inside the pressurized section and in the externally mounted fuel tanks. The ''Zarya'' is a descendant of the TKS spacecraft designed for the Russian ''Salyut'' program. The name ''Zarya'' ("Dawn") was given to the FGB because it signified the dawn of a new era of international cooperation in space. Although it was built by a Russian company, it is owned by the United States. Construct ...

Nadir
The nadir (, ; ar, نظير, naẓīr, counterpart) is the direction pointing directly ''below'' a particular location; that is, it is one of two vertical directions at a specified location, orthogonal to a horizontal flat surface. The direction opposite of the nadir is the zenith. Definitions Space science Since the concept of ''being below'' is itself somewhat vague, scientists define the nadir in more rigorous terms. Specifically, in astronomy, geophysics and related sciences (e.g., meteorology), the nadir at a given point is the local vertical direction pointing in the direction of the force of gravity at that location. The term can also be used to represent the lowest point that a celestial object reaches along its apparent daily path around a given point of observation (i.e. the object's ''lower culmination''). This can be used to describe the position of the Sun, but it is only technically accurate for one latitude at a time and only possible at the low latitudes. T ...

Russian Research Module
The Russian Research Module (RM) was to be a Russian component of the International Space Station (ISS) that provided facilities for Russian science experiments and research. History The original designs of ISS featured two research modules shaped like a rounded ''Zarya'' Functional Cargo Block, but Russian budget problems caused one of them along with the Universal Docking Module to be cancelled early in the program, leaving only one Research Module. This Research Module was scheduled to be built and launched in 2010 or later. In 2007 it was decided that, due to the continuing budget problems, the last Research Module was to be cancelled as well. According to the schedule the module with scientific designation for the Russian Orbital Segment became the FGB-2 based Multipurpose Laboratory Module ''Nauka'' approved after the cancellation of the original RM1 and RM2. Additionally the Russian Orbital Segment contains two smaller modules, initially named Mini-Research Module (MRM ...
