Progress 1
Progress 1 (Russian language, Russian: ''Прогресс 1''), was a Soviet Union, Soviet unmanned Progress (spacecraft), Progress cargo spacecraft which was launched in 1978 to resupply the Salyut 6 space station. It was the maiden flight of the Progress spacecraft, and used the Progress 7K-TG configuration. It carried supplies for the Salyut 6 EO-1, EO-1 crew aboard Salyut 6, which consisted of Soviet cosmonauts Yuri Romanenko and Georgy Grechko. The cargo carried by Progress 1 also included equipment for conducting scientific research, and fuel for adjusting the station's orbit and performing manoeuvres. Spacecraft Progress 1 was a Progress 7K-TG spacecraft. The first of forty three to be launched, it had the serial number 102. The Progress 7K-TG spacecraft was the first generation Progress (spacecraft), Progress, derived from the Soyuz 7K-T and intended for unmanned logistics missions to space stations in support of the Salyut programme. The spacecraft were also used on ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Salyut 6
Salyut 6 (russian: Салют-6; lit. Salute 6), DOS-5, was a Soviet orbital space station, the eighth station of the Salyut programme. It was launched on 29 September 1977 by a Proton rocket. Salyut 6 was the first space station to receive large numbers of crewed and uncrewed spacecraft for human habitation, crew transfer, international participation and resupply, establishing precedents for station life and operations which were enhanced on Mir and the International Space Station. Salyut 6 was the first "second generation" space station, representing a major breakthrough in capabilities and operational success. In addition to a new propulsion system and its primary scientific instrument—the BST-1M multispectral telescope—the station had two docking ports, allowing two craft to visit simultaneously. This feature made it possible for humans to remain aboard for several months. Six long-term resident crews were supported by ten short-term visiting crews who typically ...

Salyut Program
The ''Salyut'' programme (russian: Салют, , meaning "salute" or "fireworks") was the first space station programme, undertaken by the Soviet Union. It involved a series of four crewed scientific research space stations and two crewed military reconnaissance space stations over a period of 15 years, from 1971 to 1986. Two other ''Salyut'' launches failed. In one respect, ''Salyut'' had the task of carrying out long-term research into the problems of living in space and a variety of astronomical, biological and Earth-resources experiments, and on the other hand the USSR used this civilian programme as a cover for the highly secretive military ''Almaz'' stations, which flew under the ''Salyut'' designation. ''Salyut'' 1, the first station in the programme, became the world's first crewed space station. ''Salyut'' flights broke several spaceflight records, including several mission-duration records, and achieved the first orbital handover of a space station from one crew t ...

List Of Progress Missions
This is a list of missions conducted by Progress automated spacecraft. Progress is an uncrewed Russian (previously Soviet) cargo spacecraft which has been used since 1978 to deliver supplies to Soviet space stations Salyut 6, Salyut 7, Mir, and later to the International Space Station. All launches have occurred from the Baikonur Cosmodrome. More than 150 flights have been launched, all except Progress M-12M, Progress M-27M and Progress MS-04/65P have reached their destinations, with no injuries or loss of life after launch; Progress M-12M and MS-04 failed during launch, whereas Progress M-27M experienced a spacecraft loss of attitude control while in orbit. The Progress M-24 spacecraft collided with Mir during a failed docking attempt in 1994, and Progress M-34 caused serious damage to the Spektr module when it drifted off course during a docking test in 1997. The spacecraft uses the automatic Kurs docking system for rendezvous with its destination space station, where crew a ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Atmospheric Re-entry
Atmospheric entry is the movement of an object from outer space into and through the gases of an atmosphere of a planet, dwarf planet, or natural satellite. There are two main types of atmospheric entry: ''uncontrolled entry'', such as the entry of astronomical objects, space debris, or bolides; and ''controlled entry'' (or ''reentry'') of a spacecraft capable of being navigated or following a predetermined course. Technologies and procedures allowing the controlled atmospheric ''entry, descent, and landing'' of spacecraft are collectively termed as ''EDL''. Objects entering an atmosphere experience atmospheric drag, which puts mechanical stress on the object, and aerodynamic heating—caused mostly by compression of the air in front of the object, but also by drag. These forces can cause loss of mass (ablation) or even complete disintegration of smaller objects, and objects with lower compressive strength can explode. Crewed space vehicles must be slowed to subsonic speeds be ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Orbital Period
The orbital period (also revolution period) is the amount of time a given astronomical object takes to complete one orbit around another object. In astronomy, it usually applies to planets or asteroids orbiting the Sun, moons orbiting planets, exoplanets orbiting other stars, or binary stars. For celestial objects in general, the sidereal period ( sidereal year) is referred to by the orbital period, determined by a 360° revolution of one body around its primary, e.g. Earth around the Sun, relative to the fixed stars projected in the sky. Orbital periods can be defined in several ways. The tropical period is more particularly about the position of the parent star. It is the basis for the solar year, and respectively the calendar year. The synodic period incorporates not only the orbital relation to the parent star, but also to other celestial objects, making it not a mere different approach to the orbit of an object around its parent, but a period of orbital relations ...

Orbital Inclination
Orbital inclination measures the tilt of an object's orbit around a celestial body. It is expressed as the angle between a reference plane and the orbital plane or axis of direction of the orbiting object. For a satellite orbiting the Earth directly above the Equator, the plane of the satellite's orbit is the same as the Earth's equatorial plane, and the satellite's orbital inclination is 0°. The general case for a circular orbit is that it is tilted, spending half an orbit over the northern hemisphere and half over the southern. If the orbit swung between 20° north latitude and 20° south latitude, then its orbital inclination would be 20°. Orbits The inclination is one of the six orbital elements describing the shape and orientation of a celestial orbit. It is the angle between the orbital plane and the plane of reference, normally stated in degrees. For a satellite orbiting a planet, the plane of reference is usually the plane containing the planet's equator. For pla ...

Apsis
An apsis (; ) is the farthest or nearest point in the orbit of a planetary body about its primary body. For example, the apsides of the Earth are called the aphelion and perihelion. General description There are two apsides in any elliptic orbit. The name for each apsis is created from the prefixes ''ap-'', ''apo-'' (), or ''peri-'' (), each referring to the farthest and closest point to the primary body the affixing necessary suffix that describes the primary body in the orbit. In this case, the suffix for Earth is ''-gee'', so the apsides' names are ''apogee'' and ''perigee''. For the Sun, its suffix is ''-helion'', so the names are ''aphelion'' and ''perihelion''. According to Newton's laws of motion, all periodic orbits are ellipses. The barycenter of the two bodies may lie well within the bigger body—e.g., the Earth–Moon barycenter is about 75% of the way from Earth's center to its surface. If, compared to the larger mass, the smaller mass is negligible (e.g., f ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Low Earth Orbit
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth. The term ''LEO region'' is also used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. All crewed space stations to date have been within LEO. From 1968 to 1972, the Apollo program's lunar missions sent humans beyond LEO. Since the end of the Apollo program, no human spaceflights have been beyond LEO. Defining characteristics A wide variety of sources define LEO in terms of altitude. The altitude of an object in an elliptic orbit can vary significantly along the orbit. ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Soyuz 27
Soyuz 27 (russian: Союз 27, ''Union 27'') was a 1978 Soviet crewed spacecraft which flew to the orbiting Salyut 6 space station, during the mission EP-1. It was the third crewed flight to the station, the second successful docking and the first visitation mission. Once docked, it marked the first time that three spacecraft were docked together. The main function of the EP-1 mission was to swap Soyuz craft with the orbiting crew, in so doing freeing a docking port for a forthcoming supply tanker. Cosmonauts Vladimir Dzhanibekov and Oleg Makarov returned to Earth in the Soyuz 26 spacecraft after spending five days on the station. The descent module is displayed at the Sergei Pavlovich Korolyov Museum of Cosmonautics in Zhytomyr, Ukraine Ukraine ( uk, Україна, Ukraïna, ) is a country in Eastern Europe. It is the second-largest European country after Russia, which it borders to the east and northeast. Ukraine covers approximately . Prior to the ongoing Ru ...
