Mars 5M
Mars 5M, also known as Mars 79 (, or ) was a cancelled Mars sample return mission that the Soviet Union was planning in the 1970s. History Mars 5M grew out of the Mars 5NM and Mars 4NM missions that were canceled along with their intended launch vehicle, the N1 rocket, in 1974. The following year, Soviet Minister of Defence Dmitry Ustinov, at the urging of Alexander Pavlovich Vinogradov, directed Lavochkin to develop 5M as a sample return mission to launch in 1980. The launch vehicle was to be the heavy Proton A proton is a stable subatomic particle, symbol , Hydron (chemistry), H+, or 1H+ with a positive electric charge of +1 ''e'' (elementary charge).

Mars
Mars is the fourth planet from the Sun. It is also known as the "Red Planet", because of its orange-red appearance. Mars is a desert-like rocky planet with a tenuous carbon dioxide () atmosphere. At the average surface level the atmospheric pressure is a few thousandths of Earth's, atmospheric temperature ranges from and cosmic radiation is high. Mars retains some water, in the ground as well as thinly in the atmosphere, forming cirrus clouds, frost, larger polar regions of permafrost and ice caps (with seasonal snow), but no liquid surface water. Its surface gravity is roughly a third of Earth's or double that of the Moon. It is half as wide as Earth or twice the Moon, with a diameter of , and has a surface area the size of all the dry land of Earth. Fine dust is prevalent across the surface and the atmosphere, being picked up and spread at the low Martian gravity even by the weak wind of the tenuous atmosphere. The terrain of Mars roughly follows a north-south ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sample Return Mission
A sample-return mission is a spacecraft mission to collect and return samples from an extraterrestrial location to Earth for analysis. Sample-return missions may bring back merely atoms and molecules or a deposit of complex compounds such as loose material and rocks. These samples may be obtained in a number of ways, such as soil and rock excavation or a collector array used for capturing particles of solar wind or cometary debris. Nonetheless, concerns have been raised that the return of such samples to planet Earth may endanger Earth itself. To date, samples of Moon rock from Earth's Moon have been collected by robotic and crewed missions; the comet Wild 2 and the asteroids 25143 Itokawa, 162173 Ryugu, and 101955 Bennu have been visited by robotic spacecraft which returned samples to Earth; and samples of the solar wind have been returned by the robotic ''Genesis (spacecraft), Genesis'' mission. In addition to sample-return missions, samples from three identified non-terrestr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Union
The Union of Soviet Socialist Republics. (USSR), commonly known as the Soviet Union, was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 until Dissolution of the Soviet Union, it dissolved in 1991. During its existence, it was the list of countries and dependencies by area, largest country by area, extending across Time in Russia, eleven time zones and sharing Geography of the Soviet Union#Borders and neighbors, borders with twelve countries, and the List of countries and dependencies by population, third-most populous country. An overall successor to the Russian Empire, it was nominally organized as a federal union of Republics of the Soviet Union, national republics, the largest and most populous of which was the Russian SFSR. In practice, Government of the Soviet Union, its government and Economy of the Soviet Union, economy were Soviet-type economic planning, highly centralized. As a one-party state go ...

Mars 5NM
The Mars program was a series of uncrewed spacecraft launched by the Soviet Union between 1960 and 1973. The spacecraft were intended to explore Mars, and included flyby probes, landers and orbiters. Early Mars spacecraft were small, and launched by Molniya rockets. Starting with two failures in 1969, the heavier Proton-K rocket was used to launch larger 5 tonne spacecraft, consisting of an orbiter and a lander to Mars. The orbiter bus design was likely somewhat rushed into service and immature, considering that it performed very unreliably in the Venera variant after 1975. This reliability problem was common to much Soviet space hardware from the late 1960s and early 1970s and was largely corrected with a deliberate policy, implemented in the mid-1970s, of consolidating (or "debugging") existing designs rather than introducing new ones. The names of the "Mars" missions do not need to be translated, as the word "Mars" is spelled and pronounced approximately the same way in Eng ...

N1 (rocket)
The N1 (from , "Carrier Rocket"; Cyrillic: Н1) was a super heavy-lift launch vehicle intended to deliver payloads beyond low Earth orbit. The N1 was the Soviet counterpart to the US Saturn V and was intended to enable crewed travel to the Moon and beyond, with studies beginning as early as 1959. Its first stage, Block A, was the most powerful rocket stage ever flown for over 50 years, with the record standing until Starship's first integrated flight test. However, each of the four attempts to launch an N1 failed in flight, with the second attempt resulting in the vehicle crashing back onto its launch pad shortly after liftoff. Adverse characteristics of the large cluster of thirty engines and its complex fuel and oxidizer feeder systems were not revealed earlier in development because static test firings had not been conducted. The N1-L3 version was designed to compete with the United States Apollo program to land a person on the Moon, using a similar lunar orbit rendezvou ...

Dmitry Ustinov
Dmitriy Fyodorovich Ustinov (; 30 October 1908 – 20 December 1984) was a Soviet politician and a Marshal of the Soviet Union during the Cold War. He served as a Central Committee secretary in charge of the Soviet military–industrial complex from 1965 to 1976 and as Minister of Defence of the Soviet Union from 1976 until his death in 1984. Ustinov was born in the city of Samara to a Russian working-class family in 1908. Upon reaching adulthood, he joined the Communist Party in 1927 before pursuing a career in engineering. After graduating from the Institute of Military Mechanical Engineering in 1934, he became a construction engineer at the Leningrad Artillery Marine Research Institute. By 1937, he transferred to the Bolshevik "Arms" Factory where he ultimately rose to become the director. While serving as People's Commissar of Armaments during World War II, he achieved distinction within the party's ranks by successfully overseeing the evacuation of Leningrad's industr ...

Biography Alexander Vinogradov was born in a family of state ("economic") peasants (employees) in Yaroslavl province or, according to other sources, in St. Petersburg. At the end of agricultural work, the whole Vinogradov family would go to St. Petersburg to earn money, and for the summer they would come home to Petretsovo where parents would engage in farming.

Proton (rocket Family)
Proton (, 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 , making it one of the most successful heavy boosters in the history of spaceflight. The components of all Protons are manufactured in 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 among the rocket's first payloads ...
