Mare Moscoviense
; ) is a lunar mare that sits in the Moscoviense basin. It is one of the very few maria on the far side of the Moon. Geology Like Mare Marginis, this mare appears to be fairly thin. However, it is clearly centered within a large impact basin. It is also much lower than either the outer basin floor or the farside highlands. The great depth of this mare beneath the nearby highlands probably explains why mare units are so rare on the lunar farside. Very few basins on the farside were deep enough to allow mare volcanism. Thus, while large impact basins are found on both the nearside and farside, large maria are mostly found on the nearside. Mare lavas apparently could reach the surface more often and more easily there. The basin material is of the Nectarian epoch, while the mare material is of the Upper Imbrian epoch. Following the SELENE mission, scientists proposed that volcanism in Mare Moscoviense was active for at least ~1.5 Ga following the formation of the Moscoviense basin ...

Moscovy
The Grand Principality of Moscow, or Muscovy, known as the Principality of Moscow until 1389, was a late medieval Russian monarchy. Its capital was the city of Moscow. Originally established as a minor principality in the 13th century, the grand principality was transformed into a centralized Russian state in the late 15th century. Moscow became a separate principality when Daniel (), the youngest son of Alexander Nevsky, received the city and surrounding area as an appanage. By the end of the 13th century, Moscow had become one of the leading principalities within the Vladimir grand principality, alongside Tver. A struggle between the princes of Moscow and Tver began after Mikhail of Tver became grand prince in 1304. Yury () contested the title and was later made grand prince in 1318 by the khan of the Golden Horde, who held suzerainty over the princes. However, Yury lost the title four years later. Ivan I of Moscow, Ivan I () regained the title of grand prince and w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lunar Maria
The lunar maria ( ; mare ) are large, dark, basaltic plains on Earth's Moon, formed by lava flowing into ancient impact basins. They are less reflective than the "highlands" as a result of their iron-rich composition, and hence appear dark to the naked eye. The maria cover about 16% of the lunar surface, mostly on the side visible from Earth. The few maria on the far side are much smaller, residing mostly in very large craters. The traditional nomenclature for the Moon also includes one (ocean), as well as features with the names ('lake'), ('marsh'), and ('bay'). The last three are smaller than maria, but have the same nature and characteristics. The names of maria refer to sea features ( Mare Humorum, Mare Imbrium, Mare Insularum, Mare Nubium, Mare Spumans, Mare Undarum, Mare Vaporum, Oceanus Procellarum, Mare Frigoris), sea attributes ( Mare Australe, Mare Orientale, Mare Cognitum, Mare Marginis), or states of mind ( Mare Crisium, Mare Ingenii, Mare Serenit ...

Alexei Leonov
Alexei Arkhipovich Leonov. (30 May 1934 – 11 October 2019) was a Soviet and Russian cosmonaut and aviator, Soviet Air Forces, Air Force major general, writer, and artist. On 18 March 1965, he became the first person to conduct a Extravehicular activity, spacewalk, exiting the Space capsule, capsule during the Voskhod 2 mission for 12 minutes and 9 seconds. He was also selected to be the first Soviet person to Soviet crewed lunar programs, land on the Moon although the project was cancelled. In July 1975, Leonov commanded the Soyuz program, Soyuz capsule in the Apollo–Soyuz mission, which docked in space for two days with an American Apollo command and service module, Apollo capsule. Leonov was twice Hero of the Soviet Union (1965, 1975), a Major General of Aviation (1975), laureate of the USSR State Prize (1981), and a member of the Supreme Council of the United Russia party (2002–2019).

Leonov (crater)
Leonov is a small lunar impact crater that lies to the south of Mare Moscoviense, one of the few maria on the far side of the Moon. This crater has a heart-shaped outline due to an outward bulge along the northwest side. The rim of Leonov is worn, and several tiny craterlets lie along the edge. The inner walls and interior floor are relatively featureless. In 1970, the crater was named after Russian cosmonaut Alexei Leonov, the first human to perform an extravehicular activity Extravehicular activity (EVA) is any activity done by an astronaut in outer space outside a spacecraft. In the absence of a breathable atmosphere of Earth, Earthlike atmosphere, the astronaut is completely reliant on a space suit for environme ... (EVA or "spacewalk") in Earth orbit in 1965.

Freundlich-Sharonov Basin
The Freundlich-Sharonov Basin is a Pre-Nectarian impact basin on the far side of the Moon. It is named after the younger craters Freundlich near the northwest margin and Sharonov near the southwest margin. It lies east of Mare Moscoviense basin and northwest of Korolev basin. The basin is not obvious on lunar photographs, although it was discovered from analysis of Lunar Orbiter photographs. At the center is the small mare Lacus Luxuriae, just south of the oblique crater Buys-Ballot. Also at the center is a mass concentration (mascon), or gravitational high. The mascon was first identified by Doppler tracking of the Lunar Prospector spacecraft. Other craters within the basin include Anderson, Virtanen, Zernike, Dante, and the smaller Šafařík. Morse and Spencer Jones are at the margins.

Korolev (lunar Crater)
Korolev is a large lunar impact crater of the walled plain or basin type. It is a basin of Nectarian age. Korolev is named for Soviet rocket engineer Sergei Korolev. It lies on the far side of the Moon, and the northern part of its floor crosses the lunar equator. Notable nearby craters include Galois just to the southeast, Das to the south-southeast, Doppler attached to the southern rim, and Kibal'chich to the northeast. Rays of the crater Crookes (to the southwest) cover parts of the basin. The outer rim of Korolev is heavily worn and eroded, with a multitude of small craters lying across the wide rim and the low inner wall. The interior floor is relatively flat compared to the surrounding terrain, but is pock-marked with many craters of varying sizes. The most notable of these interior craters are Korolev M in the southern part of the floor, and Korolev D next to the northeast rim. Within the interior of Korolev is the remains of a second, inner ring. This is roughly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Komarov (crater)
Komarov is a lunar impact crater that lies across the southeastern edge of Mare Moscoviense, on the northern hemisphere of the far side of the Moon. It is a complex feature with an irregular appearance. The northern rim of Komarov bulges outwards into the mare, giving the crater a pear shape. The regions around the northeastern and southern rims are rugged and uneven, and the crater floor in between has been resurfaced by lava flows that have completely submerged the western third of the interior. This surface is marked by a pattern of multiple rilles that run primarily in a north–south direction, but are cracked like a drying mud bed. Along the interior of the eastern rim is a cleft-like formation that curves along the inner rim. The northwestern rim has an outer rampart where it slopes down to the plain of the neighboring mare. The crater is named after Soviet cosmonaut Vladimir Komarov Vladimir Mikhaylovich Komarov (, ; 16 March 1927 – 24 April 1967) was a Soviet ...

Tereshkova (crater)
Tereshkova is a relatively small lunar impact crater on the far side of the Moon. It is located along the western perimeter of the Mare Moscoviense, and to the southeast of the crater Feoktistov. It is named for cosmonaut Valentina Tereshkova, the first woman in space. Normally craters are named after dead people; Tereshkova is among the first group of living people to have a crater named for them. The rim of this crater resembles a rounded hexagon in outline. There is a small, cup-shaped crater near the outer edge of the southern rim. The eastern ramparts of this crater merge with the edge of the Mare Moscoviense. The rim edge is worn, but only tiny craterlets pit the surface of the edge and the crater interior. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Tereshkova.

Titov (crater)
Titov is a relatively small lunar impact crater on the far side of the Moon. The most unusual aspect of this crater is that it is located entirely within the Mare Moscoviense, one of the few maria found on the far side of the Moon. It lies to the northwest of the crater Komarov, in the northern half of the mare. It is named for cosmonaut Gherman Titov, the second person to orbit the Earth. This is a worn crater that is almost entirely surrounded by basaltic lava flows. The interior of this crater has been resurfaced by lava, and it has the same low albedo Albedo ( ; ) is the fraction of sunlight that is Diffuse reflection, diffusely reflected by a body. It is measured on a scale from 0 (corresponding to a black body that absorbs all incident radiation) to 1 (corresponding to a body that reflects ... as the surrounding terrain.

Apollo 13
Apollo 13 (April 1117, 1970) was the seventh crewed mission in the Apollo program, Apollo space program and would have been the third Moon landing. The craft was launched from Kennedy Space Center on April 11, 1970, but the landing was aborted after an oxygen tank in the Apollo command and service module#Service module (SM), service module (SM) exploded two days into the mission, disabling its electrical and life-support system. The crew, supported by backup systems on the Apollo Lunar Module, lunar module (LM), instead looped around the Moon in a circumlunar trajectory and returned safely to Earth on April 17. The mission was commanded by Jim Lovell, with Jack Swigert as Apollo command and service module#Command module (CM), command module (CM) pilot and Fred Haise as Apollo Lunar Module, Lunar Module (LM) pilot. Swigert was a late replacement for Ken Mattingly, who was grounded after exposure to rubella. A routine stir of an oxygen tank ignited damaged wire insulation insid ...

Gravity Recovery And Interior Laboratory
The Holy Grail (, , , ) is a treasure that serves as an important motif in Arthurian literature. Various traditions describe the Holy Grail as a cup, dish, or stone with miraculous healing powers, sometimes providing eternal youth or sustenance in infinite abundance, often guarded in the custody of the Fisher King and located in the hidden Grail castle. By analogy, any elusive object or goal of great significance may be perceived as a "holy grail" by those seeking such. A mysterious "grail" (Old French: ''graal'' or ''greal''), wondrous but not unequivocally holy, first appears in ''Perceval, the Story of the Grail'', an unfinished chivalric romance written by Chrétien de Troyes around 1190. Chrétien's story inspired many continuations, translators and interpreters in the later-12th and early-13th centuries, including Wolfram von Eschenbach, who portrayed the Grail as a stone in ''Parzival''. The Christian, Celtic or possibly other origins of the Arthurian grail trope are u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
