Zond 7
Zond 7, a formal member of the Soviet Zond program and unmanned version of Soyuz 7K-L1 manned Moon-flyby spacecraft, the first truly successful test of L1, was launched towards the Moon on a Proton-K D rocket on August 7, 1969, on a mission of further studies of the Moon and circumlunar space, to obtain color photography of Earth and the Moon from varying distances, and to flight test the spacecraft systems. Earth photos were obtained on August 9, 1969. On August 11, 1969, the spacecraft flew past the Moon at a distance of 1984.6 km and conducted two picture taking sessions. On its way back from the moon the spacecraft tested its radio systems by transmitting recorded voices. Zond 7 reentered Earth's atmosphere on August 14, 1969, and achieved a soft landing in a preset region south of Kustanai, Kazakhstan. On its trip the craft carried 4 turtles. A human-like tissue-equivalent phantom for radiation measurements has been placed aboard. The phantom was equipped with 20 ch ...

The Moon
The Moon is Earth's only natural satellite. It is the List of natural satellites, fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia (continent), Australia). The Moon is a planetary-mass object with a planetary differentiation, differentiated Terrestrial planet, rocky body, making it a satellite planet under the geophysical definition of planet, geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant Atmosphere of the Moon, atmosphere, hydrosphere, or Magnetic field of the Moon, magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io (moon), Io being the only satellite in the Solar System known to have a higher surface gravity and density.

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] |
Spacecraft Launched In 1969
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, 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 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Dmitrov
Dmitrov ( rus, Дмитров, p=ˈdmʲitrəf) is a types of inhabited localities in Russia, town and the administrative center of Dmitrovsky District, Moscow Oblast, Dmitrovsky District in Moscow Oblast, Russia, located to the north of Moscow on the Yakhroma River and the Moscow Canal. Population: History Dmitrov is one of the oldest urban areas in Moscow oblast. The town was originally founded by Yury Dolgoruky in 1154, where his son Vsevolod the Big Nest, Vsevolod was born. Its name is explained by the fact that Vsevolod's patron saint was Demetrius of Thessaloniki, St. Demetrius. In the 13th century, the settlement marked a point where the borders of the Grand Duchy of Moscow, Tver, and Pereslavl-Zalessky converged. The settlement itself belonged to the princes of Galich, Russia, Galich-Mersky, located much to the north, until 1364, when it was incorporated into the Grand Duchy of Moscow.

Skip Reentry
Non-ballistic atmospheric entry is a class of atmospheric entry trajectories that follow a non-ballistic trajectory by employing aerodynamic lift in the high upper atmosphere. It includes trajectories such as skip and glide. Skip is a flight trajectory where the spacecraft goes in and out the atmosphere. Glide is a flight trajectory where the spacecraft stays in the atmosphere for a sustained flight period of time. In most examples, a skip reentry roughly doubles the range of suborbital spaceplanes and reentry vehicles over the purely ballistic trajectory. In others, a series of ''skips'' allows the range to be further extended. Non-ballistic atmospheric entry was first seriously studied as a way to extend the range of ballistic missiles, but was not used operationally in this form as conventional missiles with extended range were introduced. The underlying aerodynamic concepts have been used to produce maneuverable reentry vehicles (MARV), to increase the accuracy of some mis ...

Proton (rocket Family)
Proton (Russian: Протон) (formal designation: UR-500) is an expendable launch system used for both commercial and Russian government space launches. The first Proton rocket was launched in 1965. Modern versions of the launch system are still in use as of 2022, making it one of the most successful heavy boosters in the history of spaceflight. The components of all Protons are manufactured at the Khrunichev State Research and Production Space Center factory in Moscow and Chemical Automatics Design Bureau in Voronezh, then transported to the Baikonur Cosmodrome, where they are assembled at Site 91 to form the launch vehicle. Following payload integration, the rocket is then brought to the launch pad horizontally by rail, and raised into vertical position for launch. As with many Soviet rockets, the names of recurring payloads became associated with the launch vehicle itself. The moniker "Proton" originates from a series of similarly named scientific satellites, which were amo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zond 8
Zond 8, also known as L-1 No.14, was the last in the series of circumlunar spacecraft, a member of the Soviet Zond program, designed to rehearse a piloted circumlunar flight, an uncrewed version of Soyuz 7K-L1 crewed circumlunar flight spacecraft. The project was initiated in 1965 to compete with the Americans in the race to the Moon but lost its importance once three astronauts circled the Moon on the Apollo 8 mission in December 1968. Mission Zond 8 was launched on 20 October 1970, at 19:55:39 GMT by a Proton-K / Blok D launcher from Site 81/23 of the Baikonur Cosmodrome, towards the Moon. Zond 8 had a mass of . The announced objectives of Zond 8 were investigations of the Moon and circumlunar space and testing of onboard systems and units. The spacecraft obtained photographs of Earth on 21 October from a distance of . After a mid-course correction on 22 October 1970 at a distance of from Earth. The spacecraft transmitted flight images of Earth for three days. Zond 8 reached ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zond 6
Zond 6 was a formal member of the Soviet Zond program, and an unmanned version of the Soyuz 7K-L1 manned Moon-flyby spacecraft. It was launched on a lunar flyby mission from a parent satellite (68-101B) in Earth parking orbit. The spacecraft carried scientific probes including cosmic ray and micrometeoroid detectors, as well as photographic equipment and a biological payload of flies, bacteria and turtles. The mission was a precursor to a manned circumlunar flight which the Soviets hoped could occur in December 1968, thus beating the American Apollo 8. However, after rounding the Moon, Zond 6 crashed on its return to Earth, due to a parachute failure. Mission Zond 6 was the official designation for Soyuz 7K-L1 s/n 12. It was supposed to photograph the Moon in colour and in black and white, from 8,000 km and 2,600 km ranges, then return to Earth, landing at Tyuratam, only 16 km from the launch pad. It had been a long and difficult road to develop the L1 guidance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zond Program
Zond (russian: Зонд, lit=probe) was the name given to two distinct series of Soviet robotic spacecraft launched between 1964 and 1970. The first series, based on the 3MV planetary probe, was intended to gather information about nearby planets. The second series of test spacecraft was intended as a precursor to remote-controlled robotic circumlunar loop flights, using a stripped-down variant of Soyuz spacecraft, consisting of the service and descent modules, but lacking the orbital module. Two tortoises and other lifeforms aboard Zond 5 were the first terrestrial organisms to travel around the Moon and return to Earth. Missions based on the 3MV planetary probe The first three missions were based on the model 3MV planetary probe, intended to explore Venus and Mars. After two failures, Zond 3 was sent on a test mission, becoming the second spacecraft to photograph the far side of the Moon (after Luna 3). It then continued out to the orbit of Mars in order to test telem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
