Technology
Technology is the application of Conceptual model, conceptual knowledge to achieve practical goals, especially in a reproducible way. The word ''technology'' can also mean the products resulting from such efforts, including both tangible tools such as Kitchen utensil, utensils or machines, and intangible ones such as software. Technology plays a critical role in science, engineering, and everyday life. Technological advancements have led to significant changes in society. The earliest known technology is the stone tool, used during prehistory, followed by the control of fire—which in turn contributed to the Brain size, growth of the human brain and the development of language during the Pleistocene, Ice Age, according to the cooking hypothesis. The invention of the wheel in the Bronze Age allowed greater travel and the creation of more complex machines. More recent technological inventions, including the printing press, telephone, and the Internet, have lowered barriers to ...

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 ...

Jim Lovell
James Arthur Lovell Jr. ( ; born March 25, 1928) is an American retired astronaut, naval aviator, test pilot and mechanical engineer. In 1968, as command module pilot of Apollo 8, he became, with Frank Borman and William Anders, one of the first three astronauts to fly to and orbit the Moon. He then commanded the Apollo 13 lunar mission in 1970 which, after a critical failure en route, looped around the Moon and returned safely to Earth. He has acted in a few movies, such as ''The Man Who Fell to Earth'' (1976) and '' Apollo 13 (film), Apollo 13'' (1995; uncredited). A graduate of the United States Naval Academy in Annapolis, Maryland, in the class of 1952, Lovell flew F2H Banshee night fighters.

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] |
Luna 3
Luna 3, or E-2A No.1 (), was a Soviet spacecraft launched in 1959 as part of the Luna programme. It was the first mission to photograph the far side of the Moon and the third Soviet space probe to be sent to the neighborhood of the Moon. The historic, never-before-seen views of the far side of the Moon caused excitement and interest when they were published around the world, and a tentative ''Atlas of the Far Side of the Moon'' was created from the pictures. These views showed mountainous terrain, very different from the near side, and only two dark, low-lying regions, which were named Mare Moscoviense (Sea of Moscow) and Mare Desiderii (Sea of Desire). Mare Desiderii was later found to be composed of a smaller mare, Mare Ingenii (Sea of Cleverness), and several other dark craters. The reason for this difference between the two sides of the Moon is still not fully understood, but it seems that most of the dark lavas that flowed out to produce the maria formed under the Eart ...

Luna 2
''Luna 2'' (), originally named the Second Soviet Cosmic Rocket and nicknamed Lunik 2 in contemporaneous media, was the sixth of the Soviet Union's Luna programme spacecraft launched to the Moon, E-1 No.7. It was the first spacecraft Moon landing, to touch the surface of the Moon, and the first human-made object to make contact with another celestial body. The spacecraft was launched on 12 September 1959 by the Luna (rocket), Luna 8K72 s/n I1-7B rocket. It followed a direct ascent, direct path to the Moon. In addition to the radio transmitters sending telemetry information back to Earth, the spacecraft released a sodium vapour cloud so the spacecraft's movement could be visually observed. On 13 September 1959, it impacted the Moon's surface east of Mare Imbrium near the craters Aristides, Archimedes (crater), Archimedes, and Autolycus (crater), Autolycus. Prior to impact, two sphere-shaped pennants with USSR and the launch date engraved in Cyrillic were detonated, sending penta ...

Mission Control Center
A mission control center (MCC, sometimes called a flight control center or operations center) is a facility that manages spaceflight, space flights, usually from the point of launch until landing or the end of the mission. It is part of the ground segment of spacecraft operations. A staff of flight controllers and other support personnel monitor all aspects of the mission using telemetry, and send commands to the vehicle using ground stations. Personnel supporting the mission from an MCC can include representatives of the attitude control system, electric power, power, spacecraft propulsion, propulsion, thermal, attitude dynamics and control, attitude dynamics, orbital operations and other subsystem disciplines. The training for these missions usually falls under the responsibility of the flight controllers, typically including extensive rehearsals in the MCC. Government-operated Mission Control Centers ;America * Launch Control Center, NASA Launch Control Center controls NASA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yuri Gagarin
Yuri Alekseyevich Gagarin; Gagarin's first name is sometimes transliterated as ''Yuriy'', ''Youri'', or ''Yury''. (9 March 1934 – 27 March 1968) was a Soviet pilot and cosmonaut who, aboard the first successful Human spaceflight, crewed spaceflight, became the first person to journey into outer space. Travelling on Vostok 1, Gagarin completed one orbit of Earth on 12 April 1961, with his flight taking 108 minutes. By achieving this major milestone for the Soviet Union amidst the Space Race, he became an international celebrity and was awarded many medals and titles, including his country's highest distinction: Hero of the Soviet Union. Hailing from the village of Klushino in the Russian Soviet Federative Socialist Republic, Russian SFSR, Gagarin was a foundryman at a steel plant in Lyubertsy in his youth. He later joined the Soviet Air Forces as a pilot and was stationed at the Luostari/Pechenga (air base), Luostari Air Base, near the Norway–Russia border, Norway–Soviet ...

Vostok 1
Vostok 1 (, ) was the first spaceflight of the Vostok programme and the first human spaceflight, human orbital spaceflight in history. The Vostok 3KA space capsule was launched from Baikonur Cosmodrome on 12 April 1961, with Soviet astronaut, cosmonaut Yuri Gagarin aboard, making him the first human to reach orbital speed, orbital velocity around the Earth and to complete a full orbit around the Earth. The orbital spaceflight consisted of a single orbit around Earth which skimmed the upper atmosphere at at its lowest point. The flight took 108 minutes from launch to landing. Gagarin parachuted to the ground separately from his capsule after ejecting at altitude. Background The Space Race between the Soviet Union and the United States, the two Cold War superpowers, began just before the Soviet Union launched the world's first artificial satellite, Sputnik 1, in 1957. Both countries wanted to develop spaceflight technology quickly, particularly by launching the first successf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ionosphere
The ionosphere () is the ionized part of the upper atmosphere of Earth, from about to above sea level, a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar radiation. It plays an important role in atmospheric electricity and forms the inner edge of the magnetosphere. It has practical importance because, among other functions, it influences radio propagation to distant places on Earth. Travel through this layer also impacts GPS signals, resulting in effects such as deflection in their path and delay in the arrival of the signal. History of discovery As early as 1839, the German mathematician and physicist Carl Friedrich Gauss postulated that an electrically conducting region of the atmosphere could account for observed variations of Earth's magnetic field. Sixty years later, Guglielmo Marconi received the first trans-Atlantic radio signal on December 12, 1901, in St. John's, Newfoundland (now in Canada) usin ...
