Lunar Base
A moonbase is a facility on the surface of the Moon, enabling human activity on the Moon. As such, it is different from a lunar space station in orbit around the Moon, like the planned Lunar Gateway of the Artemis program. Moonbases can be for robotic or human use, in both cases not necessarily including lunar habitation facilities. A base might be a step towards colonization. Missions to the Moon have so far realized only temporary single-mission bases, ( Tranquility Base being the first), as well as some small permanent installations. Plans for establishing facilities on the Moon that could enable sustained human activity at the Moon have been proposed and are actively pursued nationally and increasingly internationally by space agencies. Chinese concepts In 2020, China proposed the International Lunar Research Station (ILRS), a somewhat similar proposal to the Moon Village, with Roscosmos and ESA showing interest. The first steps toward establishing the ILRS will be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moon Colony
Colonization of the Moon or Lunar settlement is a process, or concept employed by some proposals, for claiming robotic or human exploitation and settlement on the Moon. Laying claim to the Moon has been declared illegal through international space law and no state has made such claims, despite having a range of probes and artificial remains on the Moon. While a range of proposals for missions of lunar colonization, exploitation or permanent exploration have been raised, current projects for establishing permanent crewed presence on the Moon are not for colonizing the Moon, but rather focus on building moonbases for exploration and to a lesser extent for exploitation of lunar resources. The commercialization of the Moon is a contentious issue for national and international lunar regulation and laws (such as the Moon treaty). History Colonization of the Moon has been imagined as early as the first half of the 17th century by John Wilkins in ''A Discourse Concerning a New P ...

Lunar Resources
The Moon bears substantial natural resources which could be exploited in the future. Potential lunar resources may encompass processable materials such as volatiles and minerals, along with geologic structures such as lava tubes that together, might enable lunar habitation. The use of resources on the Moon may provide a means of reducing the cost and risk of lunar exploration and beyond."Moon and likely initial in situ resource utilization (ISRU) applications." M. Anand, I. A. Crawford, M. Balat-Pichelin, S. Abanades, W. van Westrenen, G. Péraudeau, R. Jaumann, W. Seboldt. ''Planetary and Space Science''; volume 74; issue 1; December 2012, pp: 42—48. Insights about lunar resources gained from orbit and sample-return missions have greatly enhanced the understanding of the potential for in situ resource utilization (ISRU) at the Moon, but that knowledge is not yet sufficient to fully justify the commitment of large financial resources to implement an ISRU-based campaign.

Lunar Habitation
Lunar habitation is any human social and material structure and activity on the Moon making human habitation on the Moon. Therefore, it is more than the particular surface space habitats and more specific than the moonbases which can consist of any facility. History Lunar habitats have been designed for many different proposed moonbases. The only lunar habitats that sofar have been erected were the temporary Apollo Lunar Modules, such as ''Eagle'' of Tranquility Base, the very first. Advantages, disadvantages, problems and potential solutions Setting up structures on a natural body would provide ample sources of material for their construction, particularly for purposes such as shielding from cosmic radiation. The energy required to send objects from the Moon to space is much less than from Earth to space. This could allow the Moon to serve as a source of construction materials within cis-lunar space. Rockets launched from the Moon would require less locally produced propel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entering A Lunar Outpost
A checked tone, commonly known by the Chinese calque entering tone, is one of the four syllable types in the phonology of Middle Chinese. Although usually translated as "tone", a checked tone is not a tone in the phonetic sense but rather a syllable that ends in a stop consonant or a glottal stop. Separating the checked tone allows ''-p'', ''-t'', and ''-k'' to be treated as allophones of ''-m'', ''-n'', and ''-ng'', respectively, since they are in complementary distribution. Stops appear only in the checked tone, and nasals appear only in the other tones. Because of the origin of tone in Chinese, the number of tones found in such syllables is smaller than the number of tones in other syllables. In Chinese phonetics, they have traditionally been counted separately. For instance, in Cantonese, there are six tones in syllables that do not end in stops but only three in syllables that do so. That is why although Cantonese has only six tones, in the sense of six contrasting variatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chang'e 8
Chang'e ( ; , alternatively rendered as Chang-Er or Ch‘ang-o), originally known as Heng'e, is the Chinese goddess of the Moon. She is the subject of several legends in Chinese mythology, most of which incorporate several of the following elements: Houyi the archer, a benevolent or malevolent emperor, an elixir of life, and the Moon. She was married to Houyi. In modern times, Chang'e has been the namesake of the Chinese Lunar Exploration Program. Tales There are many tales about Chang'e, including a well-known story about her that is given as the origin of the Mid-Autumn Festival. In one version, in a very distant past, Chang'e was a beautiful woman. Ten suns had risen together into the skies and scorched the Earth, thus causing hardship for the people. Houyi the archer shot down nine of them, leaving just one Sun, and was given either two or one with enough for two elixirs of immortality as a reward. He did not consume it straight away, but let Chang'e keep it with her, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russia
Russia (, , ), or the Russian Federation, is a transcontinental country spanning Eastern Europe and Northern Asia. It is the largest country in the world, with its internationally recognised territory covering , and encompassing one-eighth of Earth's inhabitable landmass. Russia extends across eleven time zones and shares land boundaries with fourteen countries, more than any other country but China. It is the world's ninth-most populous country and Europe's most populous country, with a population of 146 million people. The country's capital and largest city is Moscow, the largest city entirely within Europe. Saint Petersburg is Russia's cultural centre and second-largest city. Other major urban areas include Novosibirsk, Yekaterinburg, Nizhny Novgorod, and Kazan. The East Slavs emerged as a recognisable group in Europe between the 3rd and 8th centuries CE. Kievan Rus' arose as a state in the 9th century, and in 988, it adopted Orthodox Christianity from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the '' Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called ''khôra'' (i.e. "space"), or in the ''Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of plac ...

Helium-3
Helium-3 (3He see also helion) is a light, stable isotope of helium with two protons and one neutron (the most common isotope, helium-4, having two protons and two neutrons in contrast). Other than protium (ordinary hydrogen), helium-3 is the only stable isotope of any element with more protons than neutrons. Helium-3 was discovered in 1939. Helium-3 occurs as a primordial nuclide, escaping from Earth's crust into its atmosphere and into outer space over millions of years. Helium-3 is also thought to be a natural nucleogenic and cosmogenic nuclide, one produced when lithium is bombarded by natural neutrons, which can be released by spontaneous fission and by nuclear reactions with cosmic rays. Some of the helium-3 found in the terrestrial atmosphere is also an artifact of atmospheric and underwater nuclear weapons testing. Much speculation has been made over the possibility of helium-3 as a future energy source. Unlike most nuclear fusion reactions, the fusion of heli ...

Isotope
Isotopes are two or more types of atoms that have the same atomic number (number of protons in their nuclei) and position in the periodic table (and hence belong to the same chemical element), and that differ in nucleon numbers ( mass numbers) due to different numbers of neutrons in their nuclei. While all isotopes of a given element have almost the same chemical properties, they have different atomic masses and physical properties. The term isotope is formed from the Greek roots isos ( ἴσος "equal") and topos ( τόπος "place"), meaning "the same place"; thus, the meaning behind the name is that different isotopes of a single element occupy the same position on the periodic table. It was coined by Scottish doctor and writer Margaret Todd in 1913 in a suggestion to the British chemist Frederick Soddy. The number of protons within the atom's nucleus is called its atomic number and is equal to the number of electrons in the neutral (non-ionized) atom. Each at ...

Chang'e Program
The Chinese Lunar Exploration Program (CLEP; ), also known as the Chang'e Project () after the Chinese moon goddess Chang'e, is an ongoing series of robotic Moon missions by the China National Space Administration (CNSA). The program incorporates lunar orbiters, landers, rovers and sample return spacecraft, launched using Long March rockets. Launches and flights are monitored by a telemetry, tracking, and command (TT&C) system, which uses radio antennas in Beijing and antennas in Kunming, Shanghai, and Ürümqi to form a VLBI antenna. A proprietary ground application system is responsible for downlink data reception. Ouyang Ziyuan, a geologist, chemical cosmologist, and the program's chief scientist, was among the first to advocate the exploitation not only of known lunar reserves of metals such as titanium, but also of helium-3, an ideal fuel for future nuclear fusion power plants. Ye Peijian serves as the program's chief commander and chief designer. Scientist Sun Ji ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CNSA
China National Space Administration (CNSA; ) is the government agency of the People's Republic of China that is responsible for civil space administration and international space cooperation, including organizing or leading foreign exchanges and cooperation in the aerospace field. An administrative agency under the Ministry of Industry and Information Technology, its headquarters are located in Haidian, Beijing. Founded in 1993, CNSA has pioneered a number of achievements in space for China despite its relatively short history, including becoming the first space agency to land on the far side of the Moon with Chang'e 4, bringing material back from the Moon with Chang'e 5, and being the second agency who successfully landed a rover on Mars with Tianwen-1. As the governing body of civil space activities, China National Space Administration does not execute any space program. The China Aerospace Science and Technology Corporation executes China's state space programs instead. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
