Russian Orbital Segment
The Russian Orbital Segment (ROS) is the name given to the components of the International Space Station (ISS) constructed in Russia and operated by the Russian Roscosmos. The ROS handles Guidance, Navigation, and Control for the entire Station. Current composition The segment currently consists of six modules, which together essentially comprise the base configuration of the cancelled Russian space station ''Mir''-2. The segment is controlled directly from Roskosmos's Mission Control Center in Moscow. The six modules are (in order of launch): * '' Zarya'' (dawn) * ''Zvezda'' (star) * ''Poisk'' (search) * ''Rassvet'' (sunrise, dawn) * ''Nauka'' (science) * ''Prichal'' (berth) The first module, ''Zarya'', otherwise known as the Functional Cargo Block or FGB, was the first component of the ISS to be launched, and provided the early station configuration with electrical power, storage, propulsion, and navigation guidance, until a short time after the Russian service modul ...

Iss Before And After Undocking Of Progress M-um From Prichal (cropped)
The International Space Station (ISS) is a large space station that was assembled and is maintained in low Earth orbit by a collaboration of five space agencies and their contractors: NASA (United States), Roscosmos (Russia), ESA (Europe), JAXA (Japan), and CSA (Canada). As the largest space station ever constructed, it primarily serves as a platform for conducting scientific experiments in microgravity and studying the space environment. The station is divided into two main sections: the Russian Orbital Segment (ROS), developed by Roscosmos, and the US Orbital Segment (USOS), built by NASA, ESA, JAXA, and CSA. A striking feature of the ISS is the Integrated Truss Structure, which connect the station’s vast system of solar panels and radiators to its pressurized modules. These modules support diverse functions, including scientific research, crew habitation, storage, spacecraft control, and airlock operations. The ISS has eight docking and berthing ports for visiting spa ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Soyuz (spacecraft)
Soyuz () is a series of spacecraft which has been in service since the 1960s, having made more than 140 flights. It was designed for the Soviet space program by the Korolev Design Bureau (now Energia (corporation), Energia). The Soyuz succeeded the Voskhod spacecraft and was originally built as part of the Soviet crewed lunar programs. It is launched atop the similarly named Soyuz (rocket family), Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan. Following the Soviet Union's dissolution, Roscosmos, the Russian space agency, continued to develop and utilize the Soyuz. Between the Space Shuttle retirement, Space Shuttle's 2011 retirement and the SpaceX Crew Dragon's 2020 debut, Soyuz was the sole means of crewed transportation to and from the International Space Station, a role it continues to fulfill. The Soyuz design has also influenced other spacecraft, including China's Shenzhou (spacecraft), Shenzhou and Russia's Progress (spacecraft), Progress cargo vehicle. The Soyu ...

Scientific Research On The ISS
Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. Modern science is typically divided into twoor threemajor branches: the natural sciences, which study the physical world, and the social sciences, which study individuals and societies. While referred to as the formal sciences, the study of logic, mathematics, and theoretical computer science are typically regarded as separate because they rely on deductive reasoning instead of the scientific method as their main methodology. Meanwhile, applied sciences are disciplines that use scientific knowledge for practical purposes, such as engineering and medicine. The history of science spans the majority of the historical record, with the earliest identifiable predecessors to modern science dating to the Bronze Age in Ancient Egypt, Egypt and Mesopotamia (). Their contributions to mathematics, astronomy, and medicine entered and shaped the Gree ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Orbital Piloted Assembly And Experiment Complex
The Orbital Piloted Assembly and Experiment Complex (, ''Orbital'nyj Pilotirujemyj Sborochno-Eksperimental'nyj Kompleks''; ОПСЭК, OPSEK) was a 2009–2017 proposed third-generation Russian modular space station for low Earth orbit. The concept was to use OPSEK to assemble components of crewed interplanetary spacecraft destined for the Moon, Mars, and possibly Saturn. The returning crew could also recover on the station before landing on Earth. Thus, OPSEK could form part of a future network of stations supporting crewed exploration of the Solar System. In early plans, the station was to consist initially of several modules from the Russian Orbital Segment (ROS) of the International Space Station (ISS). However, after studying the feasibility of this, the head of Roscosmos stated in September 2017 the intention to continue working together on the ISS. In April 2021, Roscosmos officials announced plans to exit from the ISS programme after 2024, stating concerns ...
