Kakuda Space Center
is a facility of the Japan Aerospace Exploration Agency (JAXA), located in the city of Kakuda in Miyagi Prefecture in northern Japan, specializing in the development and testing of rocket engines and space propulsion systems. The LE-5 (including the LE-5A/LE-5B version), and the LE-7 (including the LE-7A version) rocket enginese were developed at the Kakuda Space Center. History The predecessor to the Kakuda Space Center was established in 1965 as the "Kakuda Branch Laboratory" of the National Aerospace Laboratory of Japan under the aegis of the Science and Technology Agency. In 1978, the National Space Development Agency (NASDA) constructed the "Kakuda Rocket Development Center" on the same campus. Its purpose was to engage in basic research and development to raise the level of Japanese rocket propulsion technology. From the late 1980s, the Center also began research into space plane propulsion, especially scramjet technology and advanced materials research for reusable spa ...

JAXA
The is the Japanese national air and space agency. Through the merger of three previously independent organizations, JAXA was formed on 1 October 2003. JAXA is responsible for research, technology development and launch of satellites into orbit, and is involved in many more advanced missions such as asteroid exploration and possible human exploration of the Moon. Its motto is ''One JAXA'' and its corporate slogan is ''Explore to Realize'' (formerly ''Reaching for the skies, exploring space''). History On 1 October 2003, three organizations were merged to form the new JAXA: Japan's Institute of Space and Astronautical Science (ISAS), the National Aerospace Laboratory of Japan (NAL), and National Space Development Agency of Japan (NASDA). JAXA was formed as an Independent Administrative Institution administered by the Ministry of Education, Culture, Sports, Science and Technology (MEXT) and the Ministry of Internal Affairs and Communications (MIC).

Miyagi Prefecture
is a prefecture of Japan located in the Tōhoku region of Honshu. Miyagi Prefecture has a population of 2,305,596 (1 June 2019) and has a geographic area of . Miyagi Prefecture borders Iwate Prefecture to the north, Akita Prefecture to the northwest, Yamagata Prefecture to the west, and Fukushima Prefecture to the south. Sendai is the capital and largest city of Miyagi Prefecture, and the largest city in the Tōhoku region, with other major cities including Ishinomaki, Ōsaki, and Tome. Miyagi Prefecture is located on Japan's eastern Pacific coast and bounded to the west by the Ōu Mountains, the longest mountain range in Japan, with 24% of its total land area being designated as Natural Parks. Miyagi Prefecture is home to Matsushima Islands, a group of islands ranked as one of the Three Views of Japan, near the town of Matsushima. On 7 April, 2011 the biggest earthquake in Japan occurred.

LE-5
The LE-5 liquid rocket engine and its derivative models were developed in Japan to meet the need for an upper stage propulsion system for the H-I and H-II series of launch vehicles. It is a bipropellant design, using LH and LOX. Primary design and production work was carried out by Mitsubishi Heavy Industries. In terms of liquid rockets, it is a fairly small engine, both in size and thrust output, being in the 89 kN (20,000 lbf) and the more recent models the 130 kN (30,000 lbf) thrust class. The motor is capable of multiple restarts, due to a spark ignition system as opposed to the single use pyrotechnic or hypergolic igniters commonly used on some contemporary engines. Though rated for up to 16 starts and 40+ minutes of firing time, on the H-II the engine is considered expendable, being used for one flight and jettisoned. It is sometimes started only once for a nine-minute burn, but in missions to GTO the engine is often fired a second time to inject the pa ...

LE-7
The LE-7 and its succeeding upgrade model the LE-7A are staged combustion cycle LH/LOX liquid rocket engines produced in Japan for the H-II series of launch vehicles. Design and production work was all done domestically in Japan, the first major ( main/first-stage) liquid rocket engine with that claim, in a collaborative effort from the National Space Development Agency (NASDA), Aerospace Engineering Laboratory (NAL), Mitsubishi Heavy Industries, and Ishikawajima-Harima. NASDA and NAL have since been integrated into JAXA. However, a large part of the work was contracted to Mitsubishi, with Ishikawajima-Harima providing turbomachinery, and the engine is often referred to as the Mitsubishi LE-7(A). The original LE-7 was an expendable, high efficiency, medium-sized motor with sufficient thrust for use on the H-II. H-II Flight 8, only operational LE-7 failure The fuel turbopump had an issue using the originally designed inducer (a propeller-like axial pump used to raise the i ...

National Aerospace Laboratory Of Japan
The National Aerospace Laboratory of Japan (NAL) was established in July 1955. Originally known as the National Aeronautical Laboratory, it assumed its present name with the addition of the Aerospace Division in 1963. Since its establishment, it has pursued research on aircraft, rockets, and other aeronautical transportation systems, as well as peripheral technology. NAL was involved in the development of the autonomous ALFLEX aircraft and the cancelled HOPE-X spaceplane. NAL has also endeavored to develop and enhance large-scale test facilities and make them available for use by related organizations, with the aim of improving test technology in these facilities. The NAL began using computers to process data since the 1960s. It began working to develop supercomputer and numerical simulation technologies in order to execute full-scale numeric simulations. The NAL, in collaboration with Fujitsu, developed the Numerical Wind Tunnel parallel supercomputer system, which went into opera ...

Science And Technology Agency
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ...
