PGM-17 Thor
The PGM-17A Thor was the first operational ballistic missile of the United States Air Force (USAF). Named after the Norse god of thunder, it was deployed in the United Kingdom between 1959 and September 1963 as an intermediate-range ballistic missile (IRBM) with thermonuclear warheads. Thor was in height and in diameter. It was later augmented in the U.S. IRBM arsenal by the Jupiter. The Thor and later Delta families of space launch vehicles used boosters derived from the initial Thor missile. History Fearful that the Soviet Union would deploy a long-range ballistic missile before the U.S., in January 1956 the USAF began developing the Thor, a intermediate-range ballistic missile. The program proceeded quickly as a stop-gap measure, and within three years of inception the first of 20 Royal Air Force Thor squadrons became operational in the UK. The UK deployment carried the codename 'Project Emily'. One of the advantages of the design was that, unlike the Jupiter MRBM, the ...

Discoverer 10
Discoverer 10, also known as Corona 9007, was an American optical reconnaissance satellite launched on 19 Feb 1960 at 20:15:14 GMT, the seventh of ten operational flights of the Corona KH-1 spy satellite series. Background "Discoverer" was the civilian designation and cover for the Corona satellite photo-reconnaissance series of satellites managed by the Advanced Research Projects Agency of the Department of Defense and the U.S. Air Force. The primary goal of the satellites was to replace the U-2 spyplane in surveilling the Sino-Soviet Bloc, determining the disposition and speed of production of Soviet missiles and long-range bombers assess. The Corona program was also used to produce maps and charts for the Department of Defense and other US government mapping programs. The first series of Corona satellites were the Keyhole 1 (KH-1) satellites based on the Agena-A upper stage, which not only offered housing but whose engine provided attitude control in orbit. The KH-1 pay ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Echo 1A
Project Echo was the first passive communications satellite experiment. Each of the two American spacecraft, launched in 1960 and 1964, were metalized balloon satellites acting as passive reflectors of microwave signals. Communication signals were transmitted from one location on Earth and bounced off the surface of the satellite to another Earth location. The first transmissions using Echo were sent from Goldstone, California to Holmdel, New Jersey on 12 August 1960. The last Echo satellite deorbited and burned up in the atmosphere on 7 June 1969.Astronautix.com, ''Echo'' Background The concept of using orbital satellites to relay communications predated space travel, first being advanced by |
Discoverer 13
Discoverer 13 was an American optical reconnaissance satellite launched on 10 Aug 1960 at 20:37:54 GMT. The last of five test flights of the Corona KH-1 spy satellite series, it was the first fully successful flight in the Discoverer series. On 11 Aug, after 17 orbits, the satellite's reentry capsule was recovered in the Pacific Ocean by the ''Haiti Victory''. Its payload, an American flag, was presented to President Eisenhower four days later.

Discoverer 12
Discoverer 12 was an American optical reconnaissance satellite launched on 29 Jun 1960 at 22:00:44 GMT. The fourth of five test flights of the Corona KH-1 spy satellite series, it was lost when the second stage failed during launch.

Galactic Radiation And Background
Galactic Radiation and Background (GRAB) was the first successful United States orbital surveillance program, comprising a series of five Naval Research Laboratory electronic surveillance and solar astronomy satellites, launched from 1960 to 1962. Though only two of the five satellites made it into orbit, they returned a wealth of information on Soviet air defense radar capabilities as well as useful astronomical observations of the Sun. Development In 1957, the Soviet Union began deploying the S-75 Dvina surface-to-air missile, controlled by Fan Song fire control radars. This development made penetration of Soviet air space by American bombers more dangerous. The United States Air Force began a program of cataloging the rough location and individual operating frequencies of these radars, using electronic reconnaissance aircraft flying off the borders of the Soviet Union. This program provided information on radars on the periphery of the Soviet Union, but information o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transit (satellite)
The Transit system, also known as NAVSAT or NNSS (for ''Navy Navigation Satellite System''), was the first satellite navigation system to be used operationally. The radio navigation system was primarily used by the U.S. Navy to provide accurate location information to its Polaris ballistic missile submarines, and it was also used as a navigation system by the Navy's surface ships, as well as for hydrographic survey and geodetic surveying. Transit provided continuous navigation satellite service from 1964, initially for Polaris submarines and later for civilian use as well. In the Project DAMP Program, the missile tracking ship USAS American Mariner also used data from the satellite for precise ship's location information prior to positioning its tracking radars. History The Transit satellite system, sponsored by the Navy and developed jointly by DARPA and the Johns Hopkins Applied Physics Laboratory, under the leadership of Dr. Richard Kershner at Johns Hopkins, was the fir ...

Thor-Delta
The Thor-Delta, also known as Delta DM-19 or just Delta was an early American expendable launch system used for 12 orbital launches in the early 1960s. A derivative of the Thor-Able, it was a member of the Thor (rocket family), Thor family of rockets, and the first member of the Delta (rocket family), Delta family. The first stage was a PGM-17 Thor, Thor missile in the DM-19 configuration. The second stage was the Delta (rocket family), Delta, which had been derived from the earlier Able (rocket stage), Able stage. An Altair (rocket stage), Altair solid rocket motor was used as a third stage. The basic design of the original Vanguard upper stages, featuring a pressure-fed nitric acid/UDMH, regeneratively cooled engine, was kept in place, but with an improved AJ10-118 engine. More significantly, the Delta stage featured cold gas attitude control jets allowing it to be stabilized in orbit for restart and more precise burns. The Thor-Delta was the first rocket to use the combinat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Discoverer 11, also known as Corona 9008, was an American optical reconnaissance satellite launched on 15 Apr 1960 at 20:30:37 GMT. The eighth of ten operational flights of the Corona KH-1 spy satellite series, it successfully employed the first space-worthy camera film; however, Discoverer's film return capsule was lost during reentry on 16 Apr when the satellite's spin motors exploded.

Thor-Ablestar
The Thor-Ablestar, or Thor-Able-Star, also known as Thor-Epsilon was an early American expendable launch system consisting of a PGM-17 Thor missile, with an Ablestar upper stage. It was a member of the Thor (rocket family), Thor family of rockets, and was derived from the Thor-Able. The Ablestar second stage was an enlarged version of the Able (rocket stage), Able, which gave the Thor-Ablestar a greater payload capacity compared to the Thor-Able. It also incorporated restart capabilities, allowing a multiple-burn trajectory to be flown, further increasing payload, or allowing the rocket to reach different orbits. It was the first rocket to be developed with such a capability and development of the stage took a mere eight months. Nineteen Thor-Ablestar were launched between 1960–1965, of which four failed, and a fifth resulted in a partial failure, as only one of two payloads separated from the upper stage. The first failure was the launch of Courier 1A, an experimental commun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
