Progress MS-03
Progress MS-03 (), identified by NASA as Progress 64P, was a Progress spaceflight operated by Roscosmos to resupply the International Space Station (ISS). It was the first Progress MS to have an external compartment for releasing satellites. History Progress was the first cargo spacecraft to fly in space (1978), and also the first to bring freight back to Earth, thanks to a Raduga capsule. It was developed to supply the Salyut 6 space station and which was subsequently supply the crews of Salyut 7, Mir and from the International Space Station. It enabled space station crews to stay in space by bringing consumables (food, water, fuel, oxygen) and spare parts. The Progress-MS is a uncrewed freighter based on the Progress-M featuring improved avionics. This improved variant first launched on 21 December 2015. It has the following improvements: * New external compartment that enables it to deploy satellites. Each compartment can hold up to four launch containers. This P ...

''Pirs'' was launched on 14 September 2001, and was located on the ''Zvezda (ISS module), Zvezda'' module of the station. It provided the ISS with one Spacecraft docking and berthing mechanisms, docking port for Soyuz (spacecraft), Soyuz and Progress (spacecraft), Progress spacecraft, and allowed egress and ingress for Extra-vehicular activity, spacewalks by Astronaut, cosmonauts using Russian Orlan space suits.

VBK-Raduga
The VBK-Raduga capsule was a reentry capsule that was used for returning materials to Earth's surface from the space station '' Mir''. They were brought to ''Mir'' in the Progress-M cargo craft's dry cargo compartment. For return, the capsule would be substituted for the Progress' docking probe before it left the space station, and then after the Progress-M performed its deorbit burn, the capsule was ejected at 120 km altitude to reenter the atmosphere independently. It would then parachute to a landing area in Russia. Each Raduga was about 1.5 m long, 60 cm in diameter, and had an unloaded mass of about 350 kg. It could return about 150 kg of cargo back to Earth. Use of the Raduga reduced the Progress-M's cargo capacity by about 100 kg, to a maximum of about 2400 kg. The European Space Agency studied a very similar system called PARES (Payload Retrieval System), for use in combination with the Automated Transfer Vehicle The Automated Tran ...

Progress MS-03 Docked To Pirs
Progress is the movement towards a refined, improved, or otherwise desired state. In the context of progressivism, it refers to the proposition that advancements in technology, science, and social organization have resulted, and by extension will continue to result, in an improved human condition; the latter may happen as a result of direct human action, as in social enterprise or through activism, or as a natural part of sociocultural evolution. The concept of progress was introduced in the early-19th-century social theories, especially social evolution as described by Auguste Comte and Herbert Spencer. It was present in the Enlightenment's philosophies of history. As a goal, social progress has been advocated by varying realms of political ideologies with different theories on how it is to be achieved. Measuring progress Specific indicators for measuring progress can range from economic data, technical innovations, change in the political or legal system, and questions bea ...

Kurs (docking Navigation System)
Kurs (Ukrainian and russian: Курс, lit=Course) is a radio control system (type tomahook, etc.) used by the Soviet and later Russian space program. "Kurs" was developed by the Research Institute of Precision Instruments (russian: НИИ Точных Приборов, translit=NII Tochnikh Priborov), Moscow, Legostaew, before 1985 and manufactured by the Kiev Radio Factory ( uk, Київський Радіозавод, translit=Kyyivskyy Radiozavod). History Kurs was the successor to the Igla system and today provides navigation beaconing for Russian space vehicles including the Soyuz spacecraft and Progress spacecraft. The main difference between both systems is that Igla requires the space station to collaborate in the docking maneuver by reorienting itself to point the docking port to the spacecraft, while Kurs allows to dock with a fully stationary space station. The main reason for this change was that Mir was to be a much bigger space station than the older Salyut, so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

During the Middle Ages, Ukraine was the site of early Slavic expansion and the area later became a key centre of East Slavic culture under the state of Kievan Rus', which emerged in the 9th century. The state eventually disintegrated into rival regional powers and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellite Navigation
A satellite navigation or satnav system is a system that uses satellites to provide autonomous geo-spatial positioning. It allows satellite navigation devices to determine their location ( longitude, latitude, and altitude/ elevation) to high precision (within a few centimetres to metres) using time signals transmitted along a line of sight by radio from satellites. The system can be used for providing position, navigation or for tracking the position of something fitted with a receiver (satellite tracking). The signals also allow the electronic receiver to calculate the current local time to a high precision, which allows time synchronisation. These uses are collectively known as Positioning, Navigation and Timing (PNT). One set of critical vulnerabilities in satellite communications are the signals that govern positioning, navigation and timing (PNT). Failure to properly secure these transmissions could not only disrupt satellite networks but wreak havoc on a host of dep ...

Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communicat ...

Luch (satellite)
The ''Luch'' (russian: Луч; lit. ''Ray'') Satellite Data Relay Network (SDRN), also referred to as ''Altair'' and ''Gelios'', is a series of geosynchronous Russian relay satellites, used to transmit live TV images, communications and other telemetry from the Soviet/Russian space station '' Mir'', the Russian Orbital Segment (ROS) of the International Space Station and other orbital spacecraft to the Earth, in a manner similar to that of the US Tracking and Data Relay Satellite System. First generation The first generation of satellites was created by NPO-PM using the satellite platform KAUR-4 (its first use) and had the code name "Altair" (index GUKOS - 11F669). The system was conceived as part of the second generation of the Global Satellite Data Relay Network (Глобальная Космическая Командно-Ретрансляционная система (GKKRS)) and was developed by decree of the Soviet Council of Ministers of February 17, 1976 (th ...

Micrometeoroid
A micrometeoroid is a tiny meteoroid: a small particle of rock in space, usually weighing less than a gram. A micrometeorite is such a particle that survives passage through Earth's atmosphere and reaches Earth's surface. The term "micrometeoroid" was officially deprecated by the IAU in 2017, as redundant to meteoroid. Origins and orbits Micrometeoroids are very small pieces of rock or metal broken off from larger chunks of rock and debris often dating back to the birth of the Solar System. Micrometeoroids are extremely common in space. Tiny particles are a major contributor to space weathering processes. When they hit the surface of the Moon, or any airless body ( Mercury, the asteroids, etc.), the resulting melting and vaporization causes darkening and other optical changes in the regolith. Micrometeoroids have less stable orbits than meteoroids, due to their greater surface area to mass ratio. Micrometeoroids that fall to Earth can provide information on millimeter sc ...
