Lambda 4-S
Lambda is the name of a series of Japanese carrier rockets. It consisted of the types Lambda 2, LSC-3, Lambda 3, Lambda 3H, Lambda 4S, Lambda 4SC, and Lambda 4T developed jointly by Institute of Industrial Science of the University of Tokyo, Institute of Space and Astronautical Science of the University of Tokyo, and Prince Motor Company, which merged with Nissan in 1966. Lambda series rockets did not have guidance systems, as they had the potential to be converted for offensive military use, thus interpreted as a violation of Article 9 of the Japanese Constitution. However, future Japanese launch vehicles, such as the H-II, were allowed to have guidance systems. Configurations Lambda types differ regarding the upper stages used. The following table shows the actual configurations: Launches Lambda rockets were launched by ISAS, from Kagoshima pad L. On February 11, 1970, the first Japanese satellite Ohsumi was launched using a Lambda 4S rocket. The Lambda 4S was launc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lambda Rocket Launcher
Lambda (; uppercase , lowercase ; , ''lám(b)da'') is the eleventh letter of the Greek alphabet, representing the Dental, alveolar and postalveolar lateral approximants, voiced alveolar lateral approximant . In the system of Greek numerals, lambda has a value of 30. Lambda is derived from the Phoenician alphabet, Phoenician Lamed. Lambda gave rise to the Latin script, Latin L and the Cyrillic script, Cyrillic El (Cyrillic), El (Л). The ancient Alexandrine grammarians, grammarians and dramatists give evidence to the pronunciation as () in Classical Greek times. In Modern Greek, the name of the letter, Λάμδα, is pronounced . In Epichoric alphabets, early Greek alphabets, the shape and orientation of lambda varied. Most variants consisted of two straight strokes, one longer than the other, connected at their ends. The angle might be in the upper-left, lower-left ("Western" alphabets) or top ("Eastern" alphabets). Other variants had a vertical line with a horizontal or sloped ...

H-II
The H-II (H2) rocket was a Japanese satellite launch system, which flew seven times between 1994 and 1999, with five successes. It was developed by NASDA in order to give Japan a capability to launch larger satellites in the 1990s. It was the first two-stage liquid-fuelled rocket Japan made using only technologies developed domestically. It was superseded by the H-IIA rocket following reliability and cost issues. Background Prior to H-II, NASDA had to use components licensed by the United States in its rockets. In particular, crucial technologies of H-I and its predecessors were from the Delta rockets (the manufacturer of the Delta rockets, McDonnell Douglas, later Boeing and the United Launch Alliance, would later use the H-IIA's technologies (the rocket itself is the successor to the H-II) to create the Delta III, albeit short lived). Although the H-I did have some domestically produced components, such as LE-5 engine on the second stage and inertial guidance system, th ...

Space Launch Vehicles Of Japan
Space is a three-dimensional continuum containing positions and directions. In classical physics, physical space is often conceived in three linear dimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as ''spacetime''. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. In the 19th and 20th centuries mathematicians began to examine geometries that are non-Euclidean, in which space is conceived as '' curved'', rather than '' flat'', as in the Euclidean space. According to Albert Einstein's theory of general relativity, space around gravitational fields deviates from Euclidean space. Experimental tests of general relativity have confirmed that non-Euclidean geometries provide a better model for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lambda 4S
The Lambda 4S or L-4S was an experimental Japanese expendable carrier rocket. It was produced by Nissan and the Institute of Space and Astronautical Science and launched five times between 1966 and 1970 with Ohsumi technology demonstration satellites. The first four launches failed, however the fifth, launched on 11 February 1970, successfully placed Ohsumi-5, the first Japanese satellite, into orbit. The Lambda 4S consisted of four stages, with two booster rockets augmenting the first stage. SB-310 rockets were used as boosters, with an L735 first stage. The second stage was a reduced length derivative of the L735, whilst an L500 was used as the third stage. The fourth stage was an L480S. All four stages burned solid propellant. The Lambda 4S could place of payload into low Earth orbit. It was launched from the Kagoshima Space Centre. Following its retirement in 1970, a sounding rocket derived from it, the Lambda 4SC, flew three times in order to test technologies for the ...

Ohsumi (satellite)
The Ohsumi ( or Ōsumi, おおすみ) satellite, Japan’s first artificial satellite, was launched on February 11, 1970, at 04:25 UTC (Coordinated Universal Time) by the Institute of Space and Astronautical Science, Institute of Space and Aeronautical Science (''ISAS'') from the Kagoshima Space Center, which is located on the Ōsumi Peninsula, Ohsumi peninsula in Japan. This location was chosen for its strategic position in coordinating eastward launches, optimizing the rocket's trajectory. The launch vehicle was the Lambda 4S-5, a rocket developed by the ISAS of the University of Tokyo. Such an achievement marks Japan as the fourth nation to independently place a satellite into orbit. The satellite achieved an Elliptic orbit, elliptical orbit with an apogee of approximately 5,150 km and a perigee of 335 km, conducting experiments to gather data on the ionosphere and testing satellite launch technologies. Although its operational life ended within hours due to power loss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satellite
A satellite or an artificial satellite is an object, typically a spacecraft, placed into orbit around a celestial body. They have a variety of uses, including communication relay, weather forecasting, navigation ( GPS), broadcasting, scientific research, and Earth observation. Additional military uses are reconnaissance, early warning, signals intelligence and, potentially, weapon delivery. Other satellites include the final rocket stages that place satellites in orbit and formerly useful satellites that later become defunct. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which are small CubeSats. Similar satellites can work together as groups, forming constellatio ...

Uchinoura Space Center
The is a space launch facility in the Japanese town of Kimotsuki, Kagoshima Prefecture. Before the establishment of the JAXA space agency in 2003, it was simply called the (KSC). All of Japan's scientific satellites were launched from Uchinoura prior to the M-V launch vehicles being decommissioned in 2006. It continues to be used for suborbital launches, stratospheric balloons and has also been used for the Epsilon orbital launch vehicle. Additionally, the center has antennas for communication with interplanetary space probes. History Established in February 1962, the Kagoshima Space Center (KSC) was constructed on the Pacific coast of Kagoshima Prefecture in Uchinoura (now part of Kimotsuki) for the purpose of launching large rockets with probe payloads. Prior to establishment of KSC, test launches of the Pencil Rocket, Baby Rocket and Kappa Rocket had been performed at the pioneering Akita rocket test facility ( Michikawa) from the mid-1950s to the 1960s. However, pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Article 9 Of The Japanese Constitution
is a clause in the Constitution of Japan outlawing war as a means to settle international disputes involving the state. The Constitution was drafted following the surrender of Japan in World War II. It came into effect on 3 May 1947 during the occupation of Japan by the Allies, which lasted until 28 April 1952. In its text, the state formally renounces the sovereign right of belligerency and aims at an international peace based on justice and order. The article also states that, to accomplish these aims, armed forces with war potential will not be maintained. The Constitution was imposed by U.S. military occupation (Supreme Commander for the Allied Powers) to prevent rearmament of Japan in the post–World War II period. This condition was a similar prohibition placed on post-war Germany, to be overseen by the United Kingdom, after World War I. However, Germany remilitarized anyway in the decades following despite this prohibition under the Weimar Republic and later Adolf Hitle ...

Carrier Rocket
A launch vehicle is typically a rocket-powered vehicle designed to carry a payload (a crewed spacecraft or satellites) from Earth's surface or lower atmosphere to outer space. The most common form is the ballistic missile-shaped multistage rocket, but the term is more general and also encompasses vehicles like the Space Shuttle. Most launch vehicles operate from a launch pad, supported by a launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to high operating costs. An orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles use chemical propellants such as solid fuel, liquid hydrogen, kerosene, liquid oxygen, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guidance Systems
A guidance system is a virtual or physical device, or a group of devices implementing a controlling the movement of a ship, aircraft, missile, rocket, satellite, or any other moving object. Guidance is the process of calculating the changes in position, velocity, altitude, and/or rotation rates of a moving object required to follow a certain trajectory and/or altitude profile based on information about the object's state of motion. A guidance system is usually part of a Guidance, navigation and control system, whereas navigation refers to the systems necessary to calculate the current position and orientation based on sensor data like those from compasses, GPS receivers, Loran-C, star trackers, inertial measurement units, altimeters, etc. The output of the navigation system, the navigation solution, is an input for the guidance system, among others like the environmental conditions (wind, water, temperature, etc.) and the vehicle's characteristics (i.e. mass, control system avai ...
