Atlas E
The SM-65E Atlas, or Atlas-E, was an operational variant of the SM-65 Atlas, Atlas missile. It first flew on October 11, 1960, and was deployed as an operational ICBM from September 1961 until April 1966. Following retirement as an ICBM, the Atlas-E, along with the SM-65F Atlas, Atlas-F, was refurbished for orbital launches as the Atlas E/F. The last Atlas E/F launch was conducted on March 24, 1995, using a rocket which had originally been built as an Atlas E. As fully operational ICBMs, the Atlas E and F, which differed only in guidance systems, had upgraded engines and inertial control instead of the Atlas D's radio ground guidance. The ignition system was also different from the one used on the D-series, which used a "wet" start, meaning that the propellants were injected into the combustion chamber prior to ignition, and a hypergolic igniter on the fully developed version. The Atlas E/F for comparison used pyrotechnic cartridges and a dry start (ignition coming before propell ...

Convair
Convair, previously Consolidated Vultee Aircraft Corporation, was an American aircraft-manufacturing company that later expanded into rockets and spacecraft. The company was formed in 1943 by the merger of Consolidated Aircraft and Vultee Aircraft. In 1953, it was purchased by General Dynamics, and operated as their Convair Division for most of its corporate history. Convair is best known for its military aircraft; it produced aircraft such as the Convair B-36 Peacemaker and Convair B-58 Hustler strategic bombers, and the Convair F-102 Delta Dagger and Convair F-106 Delta Dart interceptors. It also manufactured the first Atlas rockets, including the rockets that were used for the crewed orbital flights of Project Mercury. The company's subsequent Atlas-Centaur design continued this success and derivatives of the design remain in use as of 2025. The company also entered the jet airliner business with its Convair 880 and Convair 990 designs. These were smaller than conte ...

Orbit
In celestial mechanics, an orbit (also known as orbital revolution) 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 u ...

Navstar 7
Navstar 7, also known as GPS I-7 and GPS SVN-7, was an American navigation satellite which was lost in a launch failure in 1981. It was intended to be used in the Global Positioning System development program. It was the seventh of eleven Block I GPS satellites to be launched, and the only one to fail to achieve orbit. Background Global Positioning System (GPS) was developed by the U.S. Department of Defense to provide all-weather round-the-clock navigation capabilities for military ground, sea, and air forces. Since its implementation, GPS has also become an integral asset in numerous civilian applications and industries around the globe, including recreational used (e.g., boating, aircraft, hiking), corporate vehicle fleet tracking, and surveying. GPS employs 24 spacecraft in 20,200 km circular orbits inclined at 55°. These vehicles are placed in 6 orbit planes with four operational satellites in each plane. Spacecraft The first eleven spacecraft (GPS Block 1) were ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

LGM-25C Titan II
The Titan II was an intercontinental ballistic missile (ICBM) developed by the Glenn L. Martin Company from the earlier HGM-25A Titan I, Titan I missile. Titan II was originally designed and used as an ICBM, but was later adapted as a Medium-lift launch vehicle, medium-lift space launch vehicle (these adaptations were designated Titan II GLV and Titan 23G) to carry payloads to Earth orbit for the United States Air Force (USAF), NASA, National Aeronautics and Space Administration (NASA) and National Oceanic and Atmospheric Administration (NOAA). Those payloads included the USAF Defense Meteorological Satellite Program (DMSP), NOAA weather satellites, and NASA's Project Gemini, Gemini crewed space capsules. The modified Titan II SLVs (Space Launch Vehicles) were launched from Vandenberg Air Force Base, California, up until 2003. Titan II missile Part of the Titan (rocket family), Titan rocket family, the Titan II ICBM was the successor to the Titan I, with double the payload ...

John Anderson Jr
John Anderson Jr. (May 8, 1917 – September 15, 2014) was an American politician who served as the 36th governor of Kansas, from 1961 until 1965.

Cuban Missile Crisis
The Cuban Missile Crisis, also known as the October Crisis () in Cuba, or the Caribbean Crisis (), was a 13-day confrontation between the governments of the United States and the Soviet Union, when American deployments of Nuclear weapons delivery, nuclear missiles in Italy and Turkey were matched by Soviet deployments of nuclear missiles in Cuba. The crisis lasted from 16to28 October 1962. The confrontation is widely considered List of nuclear close calls, the closest the Cold War came to escalating into full-scale Nuclear warfare, nuclear war. In 1961, the US government put PGM-19 Jupiter, Jupiter nuclear missiles in Italy and Turkey. It had trained a paramilitary force of Cuban exiles, expatriate Cubans, which the Central Intelligence Agency, CIA led in an attempt to Bay of Pigs Invasion, invade Cuba and overthrow its government.

Atlas ICBM Launch--'64E; 12-22-62; OSTF-1; 10-9030; 157 (note- Neg Fogged) (15908526150)
An atlas is a collection of maps; it is typically a bundle of maps of Earth or of a continent or region of Earth. Advances in astronomy have also resulted in atlases of the celestial sphere or of other planets. Atlases have traditionally been bound into book form, but today, many atlases are in multimedia formats. In addition to presenting geographical features and political boundaries, many atlases often feature geopolitical, social, religious, and economic statistics. They also have information about the map and places in it. Etymology The use of the word "atlas" in a geographical context dates from 1595 when the German-Flemish geographer Gerardus Mercator published ("Atlas or cosmographical meditations upon the creation of the universe and the universe as created"). This title provides Mercator's definition of the word as a description of the creation and form of the whole universe, not simply as a collection of maps. The volume that was published posthumously one year aft ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Spacecraft Attitude Control
Spacecraft attitude control is the process of controlling the orientation of a spacecraft (vehicle or satellite) with respect to an inertial frame of reference or another entity such as the celestial sphere, certain fields, and nearby objects, etc. Controlling vehicle attitude requires actuators to apply the torques needed to orient the vehicle to a desired attitude, and algorithms to command the actuators based on the current attitude and specification of a desired attitude. Before and during attitude control can be performed, spacecraft attitude determination must be performed, which requires sensors for absolute or relative measurement. The broader integrated field that studies the combination of sensors, actuators and algorithms is called ''guidance, navigation and control'', which also involves non-attitude concepts, such as position determination and navigation. Motivation A spacecraft's attitude must typically be stabilized and controlled for a variety of reasons. It ...
