David R. Scott
David Randolph Scott (born June 6, 1932) is an American retired test pilot and NASA astronaut who was the seventh person to walk on the Moon. Selected as part of the third group of astronauts in 1963, Scott flew to space three times and commanded Apollo 15, the fourth lunar landing; he is one of four surviving Moon walkers and the last surviving crew member of Apollo15. Before becoming an astronaut, Scott graduated from the United States Military Academy at West Point and joined the Air Force. After serving as a fighter pilot in Europe, he graduated from the Air Force Experimental Test Pilot School (Class 62C) and the Aerospace Research Pilot School (Class IV). Scott retired from the Air Force in 1975 with the rank of colonel, and more than 5,600 hours of logged flying time. As an astronaut, Scott made his first flight into space as a pilot of the Gemini 8 mission, along with Neil Armstrong, in March 1966, spending just under eleven hours in low Earth orbit. H ...

NASA Astronaut
The NASA Astronaut Corps is a unit of the United States National Aeronautics and Space Administration (NASA) that selects, trains, and provides astronauts as crew members for U.S. and international space missions. It is based at Johnson Space Center in Houston, Texas. History The first U.S. astronaut candidates were selected by NASA in 1959, for its Project Mercury with the objective of orbiting astronauts around the Earth in single-man capsules. The military services were asked to provide a list of military test pilots who met specific qualifications. After stringent screening, NASA announced its selection of the "Mercury Seven" as its first astronauts. Since then, NASA has selected 22 more groups of astronauts, opening the corps to civilians, scientists, doctors, engineers, and school teachers. As of the 2009 Astronaut Class, 61% of the astronauts selected by NASA have come from military service. NASA selects candidates from a diverse pool of applicants with a wide variety of ...

Low Earth Orbit
A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth. The term ''LEO region'' is also used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. All crewed space stations to date have been within LEO. From 1968 to 1972, the Apollo program's lunar missions sent humans beyond LEO. Since the end of the Apollo program, no human spaceflights have been beyond LEO. Defining characteristics A wide variety of sources define LEO in terms of altitude. The altitude of an object in an elliptic orbit can vary significantly along the orbit. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neil Armstrong
Neil Alden Armstrong (August 5, 1930 – August 25, 2012) was an American astronaut and aeronautical engineer who became the first person to walk on the Moon in 1969. He was also a naval aviator, test pilot, and university professor. Armstrong was born and raised in Wapakoneta, Ohio. A graduate of Purdue University, he studied aeronautical engineering; his college tuition was paid for by the U.S. Navy under the Holloway Plan. He became a midshipman in 1949 and a naval aviator the following year. He saw action in the Korean War, flying the Grumman F9F Panther from the aircraft carrier . In September 1951, while making a low bombing run, Armstrong's aircraft was damaged when it collided with an anti-aircraft cable, strung across a valley, which cut off a large portion of one wing. Armstrong was forced to bail out. After the war, he completed his bachelor's degree at Purdue and became a test pilot at the National Advisory Committee for Aeronautics (NACA) High-Speed Fligh ...

Gemini 8
Gemini 8 (officially Gemini VIII) With Gemini IV, NASA changed to Roman numerals for Gemini mission designations. was the sixth crewed spaceflight in NASA's Gemini program. It was launched on March 16, 1966, and was the 14th crewed American flight and the 22nd crewed spaceflight overall. The mission conducted the first docking of two spacecraft in orbit, but also suffered the first critical in-space system failure of a U.S. spacecraft which threatened the lives of the astronauts and required an immediate abort of the mission. The crew returned to Earth safely. Flown by pilot David Scott and command pilot Neil Armstrong, the flight marked the second time a U.S. civilian flew into space and the first time a U.S. civilian flew into orbit. Background Command pilot Neil Armstrong resigned his commission in the U.S. Naval Reserve in 1960. His flight marked the second time a U.S. civilian flew into space (after Joe Walker on X-15 Flight 90), and the first time a U.S. civilian flew in ...

Outer Space
Outer space, commonly shortened to space, is the expanse that exists beyond Earth and its atmosphere and between celestial bodies. Outer space is not completely empty—it is a near-perfect vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays. The baseline temperature of outer space, as set by the background radiation from the Big Bang, is . The plasma between galaxies is thought to account for about half of the baryonic (ordinary) matter in the universe, having a number density of less than one hydrogen atom per cubic metre and a kinetic temperature of millions of kelvins. Local concentrations of matter have condensed into stars and galaxies. Studies indicate that 90% of the mass in most galaxies is in an unknown form, called dark matter, which interacts with other matter through gravitational but not electromagnetic forces.

Aerospace Research Pilot School
The U.S. Air Force Test Pilot School (USAF TPS) is the Air Force's advanced flight training school that trains experimental test pilots, flight test engineers, and flight test navigators to carry out tests and evaluations of new aerospace weapon systems and also other aircraft of the U.S. Air Force. This school was established on 9 September 1944 as the Flight Test Training Unit at Wright-Patterson Air Force Base (AFB) in Dayton, Ohio. To take advantage of the uncongested skies, usually superb flying weather, and the lack of developed zones in the event of crashing, the test pilot school was officially moved to its present location at Edwards Air Force Base in the Mojave Desert of Southern California on 4 February 1951. The TPS was created to formalize and standardize test pilot training, reduce the high accident rate during the 1940s, and increase the number of productive test flights. In response to the increasing complexity of aircraft and their electronic systems, the school ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Military Academy At West Point
The United States Military Academy (USMA), also known metonymically as West Point or simply as Army, is a United States service academy in West Point, New York. It was originally established as a fort, since it sits on strategic high ground overlooking the Hudson River with a scenic view, north of New York City. It is the oldest of the five American service academies and educates cadets for commissioning into the United States Army. The academy was founded in 1802, one year after President Thomas Jefferson directed that plans be set in motion to establish it. It was constructed on site of Fort Clinton on West Point overlooking the Hudson, which Colonial General Benedict Arnold conspired to turn over to the British during the Revolutionary War. The entire central campus is a national landmark and home to scores of historic sites, buildings, and monuments. The majority of the campus's Norman-style buildings are constructed from gray and black granite. The campus is a po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apollo 15
Apollo 15 (July 26August 7, 1971) was the ninth crewed mission in the United States' Apollo program and the fourth to land on the Moon. It was the first J mission, with a longer stay on the Moon and a greater focus on science than earlier landings. Apollo 15 saw the first use of the Lunar Roving Vehicle. The mission began on July 26 and ended on August 7, with the lunar surface exploration taking place between July 30 and August 2. Commander David Scott and Lunar Module Pilot James Irwin landed near Hadley Rille and explored the local area using the rover, allowing them to travel further from the lunar module than had been possible on previous missions. They spent 18 hours on the Moon's surface on four extravehicular activities (EVA), and collected of surface material. At the same time, Command Module Pilot Alfred Worden orbited the Moon, operating the sensors in the scientific instrument module (SIM) bay of the service module. This suite of instruments collected da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA Astronaut Group 3
NASA Astronaut Group 3—'The Fourteen'—was a group of fourteen astronauts selected by NASA for the Gemini and Apollo program. Their selection was announced in October 1963. Seven were from the United States Air Force, four from the United States Navy, one was from the United States Marine Corps and two were civilians. Four died in training accidents before they could fly in space. All of the surviving ten flew Apollo missions; five also flew Gemini missions. Buzz Aldrin, Alan Bean, Gene Cernan and David Scott walked on the Moon. Group 3 was the first to waive the requirement of a test pilot background, though military jet fighter aircraft experience was substituted. This applied to Buzz Aldrin, Bill Anders, Gene Cernan, Roger Chaffee, Walter Cunningham and Rusty Schweickart; all the others were test pilots. On average, its members were younger, slightly taller and heavier than the previous two groups, and better educated. Background The launch of the Sputnik 1 satellite ...

List Of Apollo Astronauts
As part of the Apollo program by NASA, 24 astronauts flew 9 missions to the Moon between December 1968 and December 1972. During six successful two-man landing missions, 12 men walked on the lunar surface, six of whom drove Lunar Roving Vehicles as part of the last three missions. Three men have been to the Moon twice, one only orbited both times, while the other two landed once apiece. Apart from these 24 men, no human being has gone beyond low Earth orbit. No woman has been to the Moon, but a number of animals have orbited it, including two tortoises and five mice. Apollo missions 8 and 10– 17 were the nine crewed missions to the Moon. Apollo 4– 6 and AS-201 and AS-202 were uncrewed, while AS-203 is considered a test flight. The Apollo program included three other crewed missions – Apollo 1 (AS-204) did not launch and its crew died in a ground-based capsule fire, while Apollo 7 and Apollo 9 were low Earth orbit missions that only tested spacecraft components and do ...

NASA Distinguished Service Medal
The NASA Distinguished Service Medal is the highest award that can be bestowed by the National Aeronautics and Space Administration of the United States. The medal may be presented to any member of the federal government, including both military astronauts and civilian employees. The NASA Distinguished Service Medal is awarded to those who display distinguished service, ability, or courage, and have personally made a contribution representing substantial progress to the NASA mission. The contribution must be so extraordinary that other forms of recognition would be inadequate. Typical presentations of the NASA Distinguished Service Medal included awards to senior NASA administrators, mission control leaders, and astronauts who have completed several successful space flights. Due to the prestige of the award, the decoration is authorized for wear on active uniforms of the United States military. Another such authorized decoration is the NASA Space Flight Medal.
