Luna 22
''Luna 22'' (Ye-8-LS series) was an uncrewed space mission, part of the Soviet Luna program, also called ''Lunik 22''. Overview ''Luna 22'' was a lunar orbiter mission. The spacecraft carried imaging cameras and also had the objectives of studying the Moon's magnetic field, surface gamma ray emissions and composition of lunar surface rocks, and the gravitational field, as well as micrometeorites and cosmic rays. Luna 22 was launched into Earth parking orbit and then to the Moon. It was inserted into a circular lunar orbit on 2 June 1974. The spacecraft made many orbit adjustments over its 18-month lifetime in order to optimize the operation of various experiments, lowering the perilune to as little as 25 km. ''Luna 22'' was the second of two "advanced" lunar orbiters, the first of which being ''Luna 19 . The orbiter was'' designed to conduct extensive scientific surveys from orbit. Well in route to the Moon, ''Luna 20'' had to perform a single mid-course correction on 30 May, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Micrometeorite
A micrometeorite is a micrometeoroid that has survived entry through the Earth's atmosphere. Usually found on Earth's surface, micrometeorites differ from meteorites in that they are smaller in size, more abundant, and different in composition. The IAU officially defines meteorites as 30 micrometers to 1 meter; micrometeorites are the small end of the range (~submillimeter). They are a subset of cosmic dust, which also includes the smaller interplanetary dust particles (IDPs). Micrometeorites enter Earth's atmosphere at high velocities (at least 11 km/s) and undergo heating through atmospheric friction and compression. Micrometeorites individually weigh between 10−9 and 10−4 g and collectively comprise most of the extraterrestrial material that has come to the present-day Earth. Fred Lawrence Whipple first coined the term "micro-meteorite" to describe dust-sized objects that fall to the Earth. Sometimes meteoroids and micrometeoroids entering the Earth's atmospher ...

Satellites Orbiting The Moon
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propulsion, ...

Missions To The Moon
As part of human exploration of the Moon, numerous space missions have been undertaken to study Earth's natural satellite. Of the Moon landings, Luna 2 of the Soviet Union was the first spacecraft to reach its surface successfully, intentionally impacting the Moon on 13 September 1959. In 1966, Luna 9 became the first spacecraft to achieve a controlled soft landing, while Luna 10 became the first mission to enter orbit. Between 1968 and 1972, crewed missions to the Moon were conducted by the United States as part of the Apollo program. Apollo 8 was the first crewed mission to enter orbit in December 1968, and it was followed by Apollo 10 in May 1969. Six missions landed humans on the Moon, beginning with Apollo 11 in July 1969, during which Neil Armstrong became the first person to walk on the Moon. Apollo 13 was intended to land; however, it was restricted to a flyby due to a malfunction aboard the spacecraft. All nine crewed missions returned safely to the Earth. While the ...

Luna 23
''Luna 23'' was an unmanned space mission of the Luna program developed by the Soviet Union. Overview ''Luna 23'' was a Soviet Moon lander mission which was intended to return a lunar sample to Earth. Launched to the Moon by a Proton-K/ D, the spacecraft tipped over on its side and was damaged upon landing in Mare Crisium. The sample collecting apparatus could not operate and no samples were returned. The lander continued transmissions for three days after landing. In 1976, ''Luna 24'' landed several hundred meters away and successfully returned samples. The asteroid-like object 2010 KQ is believed to be a rocket that parted the ''Luna 23'' module after launch. ''Luna 23'' was the first modified lunar sample return spacecraft, designed to return a deep core sample of the Moon's surface (hence the change in index from Ye-8-5 to Ye-8-5M). While ''Luna 16'' and ''Luna 20'' had returned samples from a depth of 0.3 meters, the new spacecraft was designed to dig to 2.5 meters. After ...

Luna Programme
The Luna programme (from the Russian word "Luna" meaning "Moon"), occasionally called ''Lunik'' by western media, was a series of robotic spacecraft missions sent to the Moon by the Soviet Union between 1959 and 1976. Fifteen were successful, each designed as either an orbiter or lander, and accomplished many firsts in space exploration. They also performed many experiments, studying the Moon's chemical composition, gravity, temperature, and radiation. Twenty-four spacecraft were formally given the Luna designation, although more were launched. Those that failed to reach orbit were not publicly acknowledged at the time, and not assigned a Luna number. Those that failed in low Earth orbit were usually given Cosmos designations. The estimated cost of the Luna programme in 1964 was US$6–10 billion. Mission types The name ''Luna'' was used to designate a variety of spacecraft designs, to achieve several types of missions: Impactors Impactor spacecraft are designed to h ...

Luna 21
''Luna 21'' (Ye-8 series) was an unmanned space mission, and its spacecraft, of the Luna program, also called ''Lunik 21'', in 1973. The spacecraft landed on the Moon and deployed the second Soviet lunar rover, ''Lunokhod 2''. The primary objectives of the mission were to collect images of the lunar surface, examine ambient light levels to determine the feasibility of astronomical observations from the Moon, perform laser ranging experiments from Earth, observe solar X-rays, measure local magnetic fields, and study mechanical properties of the lunar surface material. Mission ''Luna 21'' carried the second successful Soviet lunar rover, ''Lunokhod 2'', and was launched less than a month after the last Apollo lunar landing. The Proton-K/ D launcher put the spacecraft into Earth parking orbit followed by translunar injection. On 12 January 1973, ''Luna 21'' was braked into a 90 × 100 km orbit about the Moon, at a 60° inclination. On 13 and 14 January, the perilune was low ...

Luna 19
''Luna 19'' (a.k.a. ''Lunik 19'') (E-8-LS series), was an unmanned space mission of the Luna program. ''Luna 19'' extended the systematic study of lunar gravitational fields and location of mascons (mass concentrations). It also studied the lunar radiation environment, the gamma-active lunar surface, and the solar wind. Photographic coverage via a television system was also obtained. Overview ''Luna 19'' was the first of the “advanced” lunar orbiters whose design was based upon the same Ye-8-class bus used for the lunar rovers and the sample collectors. For these orbiters, designated Ye-8LS, the basic “lander stage” was topped off by a wheelless Lunokhod-like frame that housed all scientific instrumentation in a pressurized container. ''Luna 19'' was launched into an Earth parking orbit on 28 September, of the year 1971 and, from this orbit, was sent toward the Moon. ''Luna 19'' entered an orbit around the Moon on 2 October 1971 after two midcourse corrections on 29 Sept ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perilune
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] |
