Break-off Phenomenon
The overview effect is a cognitive shift reported by some astronauts while viewing the Earth from outer space, space. Researchers have characterized the effect as "a state of awe with self-transcendence, self-transcendent qualities, precipitated by a particularly striking visual stimulus". The most prominent common aspects of personally experiencing the Earth from space are appreciation and perception of beauty, unexpected and even overwhelming emotion, and an increased sense of connection to other people and the Earth as a whole. The effect can cause changes in the observer's Self-schema, self concept and Value (ethics and social sciences)#Value system, value system, and can be Spiritual transformation, transformative. Immersive virtual reality simulations have been designed to try to induce the overview effect in earthbound participants. Characteristics Broadly, Yaden et al. (2016) state that the most prominent common aspects of the astronauts' experience were appreciation and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colonialism
Colonialism is the control of another territory, natural resources and people by a foreign group. Colonizers control the political and tribal power of the colonised territory. While frequently an Imperialism, imperialist project, colonialism can also take the form of settler colonialism, whereby settlers from one or multiple colonizing metropoles occupy a territory with the intention of partially or completely supplanting the existing population. Colonialism developed as a concept describing European colonial empires of the modern era, which spread globally from the 15th century to the mid-20th century, spanning 35% of Earth's land by 1800 and peaking at 84% by the beginning of World War I. European colonialism employed mercantilism and Chartered company, chartered companies, and established Coloniality of power, coloniality, which keeps the colonized socio-economically Other (philosophy), othered and Subaltern (postcolonialism), subaltern through modern biopolitics of Heterono ...

Earth Day
Earth Day is an annual event on April 22 to demonstrate support for environmental protection. First held on April 22, 1970, it now includes a wide range of events coordinated globally through earthday.org (formerly Earth Day Network) including 1 billion people in more than 193 countries. In 1969 at a UNESCO conference in San Francisco, peace activist John McConnell (peace activist), John McConnell proposed a day to honor the Earth and the concept of peace, to first be observed on March 21, 1970, the Spring (season)#Astronomical and solar reckoning, first day of spring in the northern hemisphere. This day of nature's equipoise was later sanctioned in a proclamation written by McConnell and signed by Secretary General U Thant at the United Nations. A month later, United States senator Gaylord Nelson proposed the idea to hold a nationwide environmental teach-in on April 22, 1970, and hired a young activist, Denis Hayes, to be the national coordinator. The name "Earth Day" wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environmental Movement
The environmental movement (sometimes referred to as the ecology movement) is a social movement that aims to protect the natural world from harmful environmental practices in order to create sustainable living. In its recognition of humanity as a participant in (not an enemy of) ecosystems, the movement is centered on ecology, health, as well as human rights. The environmental movement is an international movement, represented by a range of environmental organizations, from enterprises to grassroots and varies from country to country. Due to its large membership, varying and strong beliefs, and occasionally speculative nature, the environmental movement is not always united in its goals. At its broadest, the movement includes private citizens, professionals, Religion and environmentalism, religious devotees, politicians, scientists, nonprofit organizations, and individual advocates like former Wisconsin Senator Gaylord Nelson and Rachel Carson in the 20th century. Since the 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Apollo Missions
The Apollo program was a United States human spaceflight program carried out from 1961 to 1972 by the NASA, National Aeronautics and Space Administration (NASA), which landed the first List of Apollo astronauts, astronauts on the Moon. The program used the Saturn IB and Saturn V launch vehicles to lift the Apollo command and service module, Command/Service Module (CSM) and Apollo Lunar Module, Lunar Module (LM) spacecraft into space, and the Little Joe II rocket to test a launch escape system which was expected to carry the astronauts to safety in the event of a Saturn failure. Uncrewed test flights beginning in 1966 demonstrated the safety of the launch vehicles and spacecraft to carry astronauts, and four crewed flights beginning in October 1968 demonstrated the ability of the spacecraft to carry out a lunar landing mission. Apollo achieved the first crewed lunar landing on the Apollo 11 mission, when Neil Armstrong and Buzz Aldrin landed their Lunar Module Eagle, LM ''Eagle'' i ...

Lunar Orbit
In astronomy and spaceflight, a lunar orbit (also known as a selenocentric orbit) is an orbit by an object around Earth's Moon. In general these orbits are not circular. When farthest from the Moon (at apoapsis) a spacecraft is said to be at apolune, apocynthion, or aposelene. When closest to the Moon (at periapsis) it is said to be at perilune, pericynthion, or periselene. These derive from names or epithets of the moon goddess. Lunar orbit insertion (LOI) is an orbit insertion maneuver used to achieve lunar orbit. Low lunar orbit (LLO) is an orbit below altitude. These have a period of about 2 hours. They are of particular interest in the exploration of the Moon, but suffer from gravitational perturbations that make most unstable, and leave only a few orbital trajectories possible for indefinite '' frozen orbits''. These would be useful for long-term stays in LLO. Perturbation effects and low orbits Most lunar low orbits below 100 km (60 mi) are unstable. Gravitationa ...

Earthrise
''Earthrise'' is a photograph of Earth and part of the Moon's surface that was taken from lunar orbit by astronaut William Anders on December 24, 1968, during the Apollo 8 mission. Nature photographer Galen Rowell described it as "the most influential environmental photograph ever taken". Details ''Earthrise'' was taken by astronaut William Anders during the Apollo 8 mission, the first crewed voyage to orbit the Moon. For years accounts persisted that mission commander Frank Borman took the picture or at least the first in black-and-white, with the Earth's terminator touching the horizon, before Anders found a suitable 70 mm color film. In fact, all three photographs had been taken by Anders. The land mass position and cloud patterns in this image are the same as those of the color photograph entitled ''Earthrise''. The photograph was taken from lunar orbit on December 24, 1968, 16:39:39.3 UTC, with a highly modified Hasselblad 500 EL with an electric drive. T ...

William Anders
William Alison Anders (17 October 1933 – 7 June 2024) was an American United States Air Force (USAF) major general, electrical engineer, nuclear engineer, NASA astronaut, and businessman. In December 1968, he was a member of the crew of Apollo 8, the first three people to leave low-Earth orbit and travel to the Moon. Along with fellow astronauts Frank Borman and Jim Lovell, he circled the Moon ten times, and broadcast live images and commentary back to Earth, including the Christmas Eve Genesis reading. During one of the mission's lunar orbits, he took the iconic '' Earthrise'' photograph. A 1955 graduate of the United States Naval Academy, Anders was commissioned a second lieutenant in the USAF the same year and became a fighter pilot flying Northrop F-89 Scorpions equipped with AIR-2A nuclear-tipped air-to-air rockets. He hoped to study aeronautical engineering through the Air Force Institute of Technology (AFIT) of Air University, but the Aircraft Nuclear Propu ...

Apollo 8
Apollo 8 (December 21–27, 1968) was the first crewed spacecraft to leave Sphere of influence (astrodynamics), Earth's gravitational sphere of influence, and the first human spaceflight to reach the Moon. The crew orbited the Moon ten times without landing and then returned to Earth. The three astronauts—Frank Borman, Jim Lovell, James Lovell, and William Anders—were the first humans to see and photograph the far side of the Moon and an Earthrise. Apollo 8 launched on December 21, 1968, and was the second crewed spaceflight mission flown in the United States Apollo space program (the first, Apollo 7, Apollo7, stayed in Earth orbit). Apollo8 was the third flight and the first crewed launch of the Saturn V rocket. It was the first human spaceflight from the Kennedy Space Center, adjacent to Cape Canaveral Space Force Station, Cape Kennedy Air Force Station in Florida. Originally planned as the second crewed Apollo Lunar Module and Apollo command and service module, command ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fred Hoyle
Sir Fred Hoyle (24 June 1915 – 20 August 2001) was an English astronomer who formulated the theory of stellar nucleosynthesis and was one of the authors of the influential B2FH paper, B2FH paper. He also held controversial stances on other scientific matters—in particular his rejection of the "Big Bang" theory (a term coined by him on BBC Radio) in favor of the "steady-state model", and his promotion of panspermia as the origin of life on Earth. He spent most of his working life at St John's College, Cambridge and served as the founding director of the Institute of Astronomy, Cambridge, Institute of Theoretical Astronomy at Cambridge. Hoyle also wrote science fiction novels, short stories and radio plays, co-created television serials, and co-authored twelve books with his son, Geoffrey Hoyle. Biography Early life Hoyle was born near Bingley in Gilstead, West Riding of Yorkshire, England. His father Ben Hoyle was a violinist and worked in the wool trade in Bradford, an ...

''The'' is a grammatical Article (grammar), article in English language, English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the Most common words in English, most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a con ...

Overlord
An overlord in the English feudal system was a lord of a manor who had subinfeudated a particular manor, estate or fee, to a tenant. The tenant thenceforth owed to the overlord one of a variety of services, usually military service or serjeanty, depending on which form of tenure (i.e. feudal tenancy contract) the estate was held under. The highest overlord of all, or lord paramount, was the monarch, who due to his ancestor William the Conqueror's personal conquest of the Kingdom of England, ''owned'' by inheritance from him all the land in England under allodial title and had no superior overlord, "holding from God and his sword", although certain monarchs, notably King John (1199–1216) purported to grant the Kingdom of England to Pope Innocent III, who would thus have become overlord to English monarchs. A paramount lord may then be seen to occupy the apex of the feudal pyramid, or the root of the feudal tree, and such allodial title is also termed "radical title" ...
