Soyuz TM-7
Soyuz TM-7 was a crewed Soyuz spaceflight to Mir.The mission report is available here: http://www.spacefacts.de/mission/english/soyuz-TM7.htm It launched on 26 November 1988, at 15:49:34, and was the start of the fourth long duration expedition to Mir, Mir EO-4. The crew would join the third crew member of EO-4, cosmonaut/physician Valeri Polyakov, who was on Mir for the second half of EO-3. Also launched by Soyuz TM-7 was French astronaut Jean-Loup Chrétien, who would take part in the 24-day French mission known as Mir Aragatz. The spacecraft Soyuz TM-7 remained docked to Mir for the duration of EO-4. At the end of EO-4 in April 1989, due to delays in the launch schedule, Mir was left uncrewed, and all three EO-4 crew members were transported back to Earth.

Soyuz-TM
The Soyuz-TM were fourth generation (1986–2002) Soyuz spacecraft used for ferry flights to the Mir and International Space Station, ISS space stations. The Soyuz spacecraft consisted of three parts, the Orbital Module, the Descent Module and the Service Module. The first launch of the spacecraft was the uncrewed Soyuz TM-1 on May 21, 1986, where it docked with the Mir space station. The final flight was Soyuz TM-34, which docked with the International Space Station and landed November 10, 2002. Background After the Apollo–Soyuz, Apollo-Soyuz Test project in 1976, the Soyuz for crewed flights had the singular mission of supporting crewed space stations. The original Soyuz had a limited endurance when docked with a station, only about 60 to 90 days. There were two avenues for extending the duration of missions past this. The first avenue was to make upgrades to increase the Soyuz spacecraft's endurance. The Soyuz-T could last 120 days and the Soyuz-TM could last 180 days ...

Mir EO-4
Mir EO-4 (also called Principal Expedition 4) was the fourth long-duration expedition to the Soviet space station Mir. The expedition began in November 1988, when crew members Commander Aleksandr Volkov and Flight Engineer Sergei Krikalev arrived at the station via the spacecraft Soyuz TM-7. The third crew member of EO-4, Valeri Polyakov, was already aboard Mir, having arrived in August 1988 part way through the previous expedition, Mir EO-3. The expedition lasted for five months, and at its conclusion Mir was left unmanned until the launch of Mir EO-5 in September 1989. This ended a continuous habitation of the space station which began in February 1987, with the arrival of the crew of Mir EO-2. Background The previous long-duration expedition to Mir, EO-3, was intended to break the record for spaceflight duration of 326 days set by Yuri Romanenko during Mir EO-2. The physician Valeri Polyakov was sent to the station part way through EO-3 so that he could observe the cosmonauts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Degree (angle)
A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane (mathematics), plane angle in which one Turn (geometry), full rotation is 360 degrees. It is not an SI unit—the SI unit of angular measure is the radian—but it is mentioned in the SI Brochure, SI brochure as an Non-SI units mentioned in the SI, accepted unit. Because a full rotation equals 2 radians, one degree is equivalent to radians. History The original motivation for choosing the degree as a unit of rotations and angles is unknown. One theory states that it is related to the fact that 360 is approximately the number of days in a year. Ancient astronomers noticed that the sun, which follows through the ecliptic path over the course of the year, seems to advance in its path by approximately one degree each day. Some ancient calendars, such as the Iranian calendar, Persian calendar and the Babylonian calendar, used 360 days for a year. ...

Inclination
Orbital inclination measures the tilt of an object's orbit around a celestial body. It is expressed as the angle between a Plane of reference, reference plane and the orbital plane or Axis of rotation, 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 degree (angle), degrees. For a satellite orbiting a planet, the plane of reference is usually ...

Apogee
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] |

Pound (mass)
The pound or pound-mass is a unit of mass used in British imperial and United States customary systems of measurement. Various definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly , and which is divided into 16 avoirdupois ounces. The international standard symbol for the avoirdupois pound is lb; an alternative symbol is lbm (for most pound definitions), # ( chiefly in the U.S.), and or ″̶ (specifically for the apothecaries' pound). The unit is descended from the Roman (hence the abbreviation "lb"). The English word ''pound'' is cognate with, among others, German , Dutch , and Swedish . These units are historic and are no longer used (replaced by the metric system). Usage of the unqualified term ''pound'' reflects the historical conflation of mass and weight. This accounts for the modern distinguishing terms ''pound-mass'' and '' pound-force''. Etymology The word 'pound' and its cognates ultim ...

Kilogram
The kilogram (also kilogramme) is the unit of mass in the International System of Units (SI), having the unit symbol kg. It is a widely used measure in science, engineering and commerce worldwide, and is often simply called a kilo colloquially. It means 'one thousand grams'. The kilogram is defined in terms of the second and the metre, both of which are based on fundamental physical constants. This allows a properly equipped metrology laboratory to calibrate a mass measurement instrument such as a Kibble balance as the primary standard to determine an exact kilogram mass. The kilogram was originally defined in 1795 as the mass of one litre of water. The current definition of a kilogram agrees with this original definition to within 30 parts per million. In 1799, the platinum ''Kilogramme des Archives'' replaced it as the standard of mass. In 1889, a cylinder of platinum-iridium, the International Prototype of the Kilogram (IPK), became the standard of the unit of mass for ...

Mass
Mass is an intrinsic property of a body. It was traditionally believed to be related to the quantity of matter in a physical body, until the discovery of the atom and particle physics. It was found that different atoms and different elementary particles, theoretically with the same amount of matter, have nonetheless different masses. Mass in modern physics has multiple definitions which are conceptually distinct, but physically equivalent. Mass can be experimentally defined as a measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied. The object's mass also determines the strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg). In physics, mass is not the same as weight, even though mass is often determined by measuring the object's weight using a spring scale, rather than balance scale comparing it directly with known masses. An object on the Moon would weigh le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
