SOLRAD 2
SOLRAD (SOLar RADiation) 2 was the public designation for a combination surveillance and solar X-rays and ultraviolet scientific satellite, the second in the SOLRAD program developed by the United States Navy's Naval Research Laboratory. The SOLRAD scientific package aboard the satellite provided cover for the GRAB (Galactic Radiation and Background) electronic surveillance package, the mission of which was to map the Soviet Union's air defense radar network. SOLRAD 2 was launched along with Transit 3A atop a Thor-Ablestar rocket on 30 November 1960, but both satellites failed to reach orbit when the booster flew off course and was destroyed, raining debris over Cuba, which prompted official protests from the Cuban government. As a result, future SOLRAD flights were programmed to avoid a Cuban flyover during launch. Background In 1957, the Soviet Union began deploying the S-75 Dvina surface-to-air missile, controlled by Fan Song fire control radars. This development mad ...

Naval Research Laboratory
The United States Naval Research Laboratory (NRL) is the corporate research laboratory for the United States Navy and the United States Marine Corps. It was founded in 1923 and conducts basic scientific research, applied research, technological development and prototyping. The laboratory's specialties include plasma physics, space physics, materials science, and tactical electronic warfare. NRL is one of the first US government scientific R&D laboratories, having opened in 1923 at the instigation of Thomas Edison, and is currently under the Office of Naval Research. As of 2016, NRL was a Navy Working Capital Fund activity, which means it is not a line-item in the US Federal Budget. Instead of direct funding from Congress, all costs, including overhead, were recovered through sponsor-funded research projects. NRL's research expenditures were approximately $1 billion per year.

Project Vanguard
Project Vanguard was a program managed by the United States Navy Naval Research Laboratory (NRL), which intended to launch the first artificial satellite into low Earth orbit using a Vanguard rocket. as the launch vehicle from Cape Canaveral Missile Annex, Florida. In response to the launch of Sputnik 1 on 4 October 1957, the U.S. restarted the Explorer program, which had been proposed earlier by the Army Ballistic Missile Agency (ABMA). Privately, however, the Central Intelligence Agency (CIA) and President Dwight D. Eisenhower were aware of progress being made by the Soviets on Sputnik from secret spy plane imagery. Together with the Jet Propulsion Laboratory (JPL), ABMA built Explorer 1 and launched it on 1 February 1958 ( UTC). Before work was completed, however, the Soviet Union launched a second satellite, Sputnik 2, on 3 November 1957. Meanwhile, the spectacular televised failure of Vanguard TV3 on 6 December 1957, deepened American dismay over the country's position in ...

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fan Song
The Fan Song is the NATO reporting name for SNR-75 series of trailer-mounted E band/ F band and G band fire control and tracking radars for use with the Soviet SA-2 Guideline surface-to-air missile system. Description The Fan Song radars are capable of tracking a single target at a time, and can guide up to three missiles at once to it. The radars feature two orthogonal antennas, one for azimuth and one for elevation, which can operate in a track-while-scan mode. These antennas transmit 10 × 2 degree or 7.5 x 1.5 degree beams and perform a 'flapping' motion as they scan their sectors. The Fan Song E includes two additional parabolic dishes for narrow beam and LORO tracking modes.

Surface-to-air Missile
A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground to destroy aircraft or other missiles. It is one type of anti-aircraft system; in modern armed forces, missiles have replaced most other forms of dedicated anti-aircraft weapons, with anti-aircraft guns pushed into specialized roles. The first attempt at SAM development took place during World War II, but no operational systems were introduced. Further development in the 1940s and 1950s led to operational systems being introduced by most major forces during the second half of the 1950s. Smaller systems, suitable for close-range work, evolved through the 1960s and 1970s, to modern systems that are man-portable. Shipborne systems followed the evolution of land-based models, starting with long-range weapons and steadily evolving toward smaller designs to provide a layered defence. This evolution of design increasin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
S-75 Dvina
The S-75 (Russian: С-75; NATO reporting name SA-2 Guideline) is a Soviet-designed, high-altitude air defence system, built around a surface-to-air missile with command guidance. Following its first deployment in 1957 it became one of the most widely deployed air defence systems in history. It scored the first destruction of an enemy aircraft by a surface-to-air missile, with the shooting down of a Taiwanese Martin RB-57D Canberra over China on 7 October 1959 that was hit by a salvo of three V-750 (1D) missiles at an altitude of 20 km (65,600 ft). This success was credited to Chinese fighter aircraft at the time to keep the S-75 program secret. This system first gained international fame when an S-75 battery, using the newer, longer-range, higher-altitude V-750VN (13D) missile was deployed in the 1960 U-2 incident, when it shot down the Lockheed U-2, U-2 of Francis Gary Powers overflying the Soviet Union on May 1, 1960. The system was also deployed in Cuba during the C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
