Launch Complex 11
Launch Complex 11 (LC-11) at Cape Canaveral Space Force Station, Florida, is a launch complex used by Atlas missiles between 1958 and 1964. It is the southernmost of the launch pads known as Missile Row. When it was built, it, along with complexes 12, 13 and 14, featured a more robust design than many contemporary pads, due to the greater power of the Atlas compared to other rockets of the time. It was larger, and featured a concrete launch pedestal that was tall and a reinforced blockhouse. The rockets were delivered to the launch pad by a ramp on the southwest side of the launch pedestal. Thirty-two Atlas B, D, E and F missiles were launched on suborbital test flights from LC-11. The first launch to use the complex was Atlas 3B, the first flight of a complete Atlas, which was launched on 19 July 1958. In addition to the suborbital tests, one orbital launch was conducted from the complex. On 18 December 1958, Atlas 10B launched SCORE, the world's first communications sa ...

SCORE (satellite)
SCORE (Signal Communications by Orbiting Relay Equipment) was the world's first purpose-built communications satellite. Launched aboard an American Atlas rocket on December 18, 1958, SCORE provided the second test of a communications relay system in space (the first having been provided by the USAF/NASA's Pioneer 1),) the first broadcast of a human voice from space, and the first successful use of the Atlas as a launch vehicle. It captured world attention by broadcasting a Christmas message via shortwave radio from U.S. President Dwight D. Eisenhower through an on-board tape recorder. The satellite was popularly dubbed "''The Talking Atlas''". SCORE, as a geopolitical strategy, placed the United States at an even technological par with the Soviet Union as a highly functional response to the Sputnik 1 and Sputnik 2 satellites. Background The six-month effort was the first endeavor of the then-new Advanced Research Projects Agency (ARPA) headed by Roy Johnson, and proved that a ...

Cape Canaveral Air Force Station Launch Complex 13
Launch Complex 13 (LC-13) was a launch complex at Cape Canaveral Space Force Station, the third-most southerly of the original launch complexes known as Missile Row, lying between LC-12 and LC-14. In 2015, the LC-13 site was leased by SpaceX and was renovated for use as Landing Zone 1 and Landing Zone 2, the company's East Coast landing location for returning Falcon 9 and Falcon Heavy launch vehicle booster stages. LC-13 was originally used for test launches of the SM-65 Atlas and subsequently for operational Atlas launches from 1958 to 1978. It was the most-used and longest-serving of the original four Atlas pads.The original four Atlas pads were LC-11, 12, 13 and 14. It was inactive between 1980 and 2015. On 16 April 1984, it was added to the US National Register of Historic Places; however it was not maintained and gradually deteriorated. On 6 August 2005 the mobile service tower was demolished as a safety precaution due to structural damage by corrosion.The structure ...

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] |
Communications Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications sate ...

Orbit
In celestial mechanics, an orbit is the curved trajectory of an object such as the trajectory of a planet around a star, or of a natural satellite around a planet, or of an artificial satellite around an object or position in space such as a planet, moon, asteroid, or Lagrange point. Normally, orbit refers to a regularly repeating trajectory, although it may also refer to a non-repeating trajectory. To a close approximation, planets and satellites follow elliptic orbits, with the center of mass being orbited at a focal point of the ellipse, as described by Kepler's laws of planetary motion. For most situations, orbital motion is adequately approximated by Newtonian mechanics, which explains gravity as a force obeying an inverse-square law. However, Albert Einstein's general theory of relativity, which accounts for gravity as due to curvature of spacetime, with orbits following geodesics, provides a more accurate calculation and understanding of the exact mechanics of orbi ...

Blockhouse
A blockhouse is a small fortification, usually consisting of one or more rooms with loopholes, allowing its defenders to fire in various directions. It is usually an isolated fort in the form of a single building, serving as a defensive strong point against any enemy that does not possess siege equipment or, in modern times, artillery, air force and cruise missiles. A fortification intended to resist these weapons is more likely to qualify as a fortress or a redoubt, or in modern times, be an underground bunker. However, a blockhouse may also refer to a room within a larger fortification, usually a battery or redoubt. Etymology The term '' blockhouse'' is of uncertain origin, perhaps related to Middle Dutch '' blokhus'' and 18th-century French '' blocus'' (blockade). In ancient Greece Blockhouses existed in ancient Greece, for example the one near Mycenae. Early blockhouses in England Early blockhouses were designed solely to protect a particular area by the use of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Canaveral Air Force Station Launch Complex 14
Launch Complex 14 (LC-14) is a launch site at Cape Canaveral Space Force Station in Florida. LC-14 was used for various manned and unmanned Atlas launches, including the February 1962, ''Friendship 7'' flight aboard which John Glenn became the first American to orbit the Earth. History LC-14 was the first Atlas pad in operation and hosted the test flights in 1957–58. It was also the only one of the original four pads to never have a booster explode on it. By 1959, it was decided to convert the pad for the Atlas D missile and space launches, and a large service tower was added early in the year. The first Atlas flown from the renovated LC-14 was Missile 7D on May 18; however, a problem with the launcher hold-down arms damaged the missile and caused its explosion shortly after launch. This was traced to improper procedures during the renovation of the pad and was quickly fixed. The first space launch off of LC-14 was the Big Joe Mercury test in September. As the designated Merc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Canaveral Air Force Station Launch Complex 12
Launch Complex 12 (LC-12) at Cape Canaveral Space Force Station, Florida was a launch pad used by Atlas rockets and missiles between 1958 and 1967. It was the second-most southern of the pads known as Missile Row, between LC-11 to the south and LC-13 to the north. Along with Complexes 11, 13 and 14, 12 featured a more robust design than many contemporary pads, due to the greater power of the Atlas compared to other rockets of the time. It was larger, and featured a concrete launch pedestal that was tall and a reinforced blockhouse. The rockets were delivered to the launch pad by means of a ramp on the southwest side of the launch pedestal. Atlas A, C and D missiles were tested from the site. It was also used for orbital launches of Atlas-Able and later Atlas-Agena rockets, and two Project FIRE suborbital tests for Project Apollo, using Atlas D rockets. LC-12's first launch was Atlas 10A on January 10, 1958. During the second half of the year, a larger umbilical service t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Canaveral Space Force Station
Cape Canaveral Space Force Station (CCSFS) is an installation of the United States Space Force's Space Launch Delta 45, located on Cape Canaveral in Brevard County, Florida. Headquartered at the nearby Patrick Space Force Base, the station is the primary launch site for the Space Force's Eastern RangeCAST 1999, p. 1-12. with three launch pads currently active (Space Launch Complexes 37B, 40, and 41).
