Luna 7
''Luna 7'' (E-6 or Ye-6 series) was an uncrewed space mission of the Soviet Luna program, also called Lunik 7. Mission The ''Luna 7'' spacecraft was intended to achieve a soft landing on the Moon. However, due to premature retrofire and cutoff of the retrorockets, the spacecraft impacted the lunar surface in Oceanus Procellarum. Unlike its predecessors, Luna 7 successfully carried out its mid-course correction on October 5 on the way to the Moon, in anticipation of a soft-landing two days later. However, immediately prior to planned retro-fire during the approach to the lunar surface, the spacecraft suddenly lost attitude control and failed to regain it. Automatic programmed systems then prevented the main engine from firing. As controllers observed helplessly, ''Luna 7'' plummeted to the lunar surface at a very high speed, crashing at 22:08:24 UT on October 7, 1965, west of the Kepler crater, relatively near the actual intended target. Impact coordinates were . Later inves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luna Program
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. The programme accomplished many firsts in space exploration, including first flyby of the Moon, first impact of the Moon and first photos of the far side of the Moon. Each mission was designed as either an orbiter or lander. 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$6–10 billion (equivalent to US$– billion in ). The Luna 25 mission also continues ...

Spacecraft Launched In 1965
A spacecraft is a vehicle that is designed to fly and operate in outer space. Spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit (space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific research are space prob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Missions To The Moon
Missions to the Moon have been numerous and include some of the earliest space missions, conducting exploration of the Moon since 1959. The first partially successful lunar mission was Luna 1 (January 1959), the first probe to leave Earth and fly past another astronomical body. Soon after that the first Moon landing and the first landing on any extraterrestrial body was performed by Luna 2, which intentionally impacted the Moon on 14 September 1959. The far side of the Moon, which is always facing away from Earth due to tidal locking, was seen for the first time by Luna 3 in (7 October 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, and in 1968 Zond 5 became the first mission to carry terrestrial lifeforms (tortoises) to close proximity of the Moon through a circumlunar approach. The first crewed missions to the Moon were pursued by the Soviet Union and the United States, be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Celestial Navigation
Celestial navigation, also known as astronavigation, is the practice of position fixing using stars and other celestial bodies that enables a navigator to accurately determine their actual current physical position in space or on the surface of the Earth without relying solely on estimated positional calculations, commonly known as dead reckoning. Celestial navigation is performed without using satellite navigation or other similar modern electronic or digital positioning means. Celestial navigation uses "sights," or timed angular measurements, taken typically between a celestial body (e.g., the Sun, the Moon, a planet, or a star) and the visible horizon. Celestial navigation can also take advantage of measurements between celestial bodies without reference to the Earth's horizon, such as when the Moon and other selected bodies are used in the practice called "lunars" or the Lunar distance (navigation), lunar distance method, used for determining precise time when time is u ...

Kepler (lunar Crater)
Kepler is a Lunar craters, lunar impact crater that lies between the Oceanus Procellarum to the west and Mare Insularum in the east. To the southeast is the crater Encke (crater), Encke. Kepler is named for the 17th century German astronomer and mathematician Johannes Kepler. Description Kepler is most notable for the prominent ray system that covers the surrounding Lunar mare, mare. The rays extend for well over 300 kilometers, overlapping the rays from other craters. Kepler has a small wikt:rampart, rampart of ejecta surrounding the exterior of its high rim. The outer wall is not quite circular, and possesses a slightly polygonal form. The interior walls of Kepler are slumped and slightly wiktionary:terrace, terraced, descending to an uneven floor and a minor central rise. One of the rays from Tycho (crater), Tycho, when extended across the Oceanus Procellarum, intersects this crater. This was a factor in the choice of the crater's name when Giovanni Riccioli was creating hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spacecraft Attitude Control
Spacecraft attitude control is the process of controlling the orientation of a spacecraft (vehicle or satellite) with respect to an inertial frame of reference or another entity such as the celestial sphere, certain fields, and nearby objects, etc. Controlling vehicle attitude requires actuators to apply the torques needed to orient the vehicle to a desired attitude, and algorithms to command the actuators based on the current attitude and specification of a desired attitude. Before and during attitude control can be performed, spacecraft attitude determination must be performed, which requires sensors for absolute or relative measurement. The broader integrated field that studies the combination of sensors, actuators and algorithms is called ''guidance, navigation and control'', which also involves non-attitude concepts, such as position determination and navigation. Motivation A spacecraft's attitude must typically be stabilized and controlled for a variety of reasons. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oceanus Procellarum
Oceanus Procellarum ( ; from ) is a vast lunar mare on the western edge of the near side of the Moon. It is the only one of the lunar maria to be called an "Oceanus" (ocean), due to its size: Oceanus Procellarum is the largest of the maria ("seas"), stretching more than across its north–south axis and covering roughly , accounting for 10.5% of the total lunar surface area. Characteristics Like all lunar maria, Oceanus Procellarum was formed by ancient volcanic eruptions resulting in basaltic floods that covered the region in a thick, nearly flat layer of solidified magma. Basalts in Oceanus Procellarum have been estimated to be as young as one billion years old. Unlike the other lunar maria, however, Oceanus Procellarum may or may not be contained within a single, well-defined impact basin. Around its edges lie many minor bays and seas, including Sinus Roris to the north, and Mare Nubium, Mare Humorum and to the south. To the northeast, Oceanus Procellarum is separated ...
