Hakucho (train)
Hakucho (also known as CORSA-b before launch; CORSA stands for Cosmic Radiation Satellite) was Japan's first X-ray astronomy satellite, developed by the Institute of Space and Aeronautical Science (then a division of the University of Tokyo). It was launched from the Kagoshima Space Center by the ISAS M-3C rocket on the M-3C-4 mission on February 21, 1979 and reentered the atmosphere on April 15, 1985. Hakucho was a replacement for the CORSA satellite which failed to launch due to rocket failure on February 4, 1976.

Institute Of Space And Astronautical Science
(ISAS) is a Japanese national research organization of astrophysics using rockets, astronomical satellites and interplanetary probes which played a major role in Japan's space development. Since 2003, it is a division of Japan Aerospace Exploration Agency (JAXA). History The ISAS originated as part of the Institute of Industrial Science of the University of Tokyo, where Hideo Itokawa experimented with miniature solid-fuel rockets ( Pencil Rocket and Baby Rocket) in the 1950s. This experimentation eventually led to the development of the Κ (''Kappa'') sounding rocket, which was used for observations during the International Geophysical Year (IGY). By 1960, the Κ-8 rocket had reached an altitude of 200 km. In 1964, the rocket group and the ''Institute of Aeronautics'', along with scientific ballooning team, were merged to form within the University of Tokyo. The rocket evolved into the L (''Lambda'') series, and, in 1970, L-4S-5 was launched as Japan's firs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coordinated Universal Time
Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. It is within about one second of mean solar time (such as UT1) at 0° longitude (at the IERS Reference Meridian as the currently used prime meridian) and is not adjusted for daylight saving time. It is effectively a successor to Greenwich Mean Time (GMT). The coordination of time and frequency transmissions around the world began on 1 January 1960. UTC was first officially adopted as CCIR Recommendation 374, ''Standard-Frequency and Time-Signal Emissions'', in 1963, but the official abbreviation of UTC and the official English name of Coordinated Universal Time (along with the French equivalent) were not adopted until 1967. The system has been adjusted several times, including a brief period during which the time-coordination radio signals broadcast both UTC and "Stepped Atomic Time (SAT)" before a new UTC was adopted in 1970 and implemented in 1972. This change also a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, 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, progress in rocket developm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kagoshima Prefecture
is a prefecture of Japan located on the island of Kyushu and the Ryukyu Islands. Kagoshima Prefecture has a population of 1,599,779 (1 January 2020) and has a geographic area of 9,187 km2 (3,547 sq mi). Kagoshima Prefecture borders Kumamoto Prefecture to the north and Miyazaki Prefecture to the northeast. Kagoshima is the capital and largest city of Kagoshima Prefecture, with other major cities including Kirishima, Kanoya, and Satsumasendai. Kagoshima Prefecture is located at the southernmost point of Kyūshū and includes the Satsunan Islands group of the Ryukyu Islands. Kagoshima Prefecture's mainland territory extends from the Ariake Sea to Shibushi Bay on the Pacific Ocean coast, and is characterized by two large peninsulas created by Kagoshima Bay. Kagoshima Prefecture formed the core of the Satsuma Domain, ruled from Kagoshima Castle, one of the most important Japanese domains of the Edo period and the Meiji Restoration.

Satellite
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. 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 Transponder (satellite communications), transponders. Many satellites use a Satellite bus, standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming Satellite constellation, constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio Broadcast relay station, relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mu (rocket)
The Mu, also known as M, was a series of Japanese solid-fueled carrier rockets, which were launched from Uchinoura between 1966 and 2006. Originally developed by Japan's Institute of Space and Astronautical Science, Mu rockets were later operated by Japan Aerospace Exploration Agency following ISAS becoming part of it. Early Japanese carrier rockets The first Mu rocket, the Mu-1 made a single, sub-orbital, test flight, on 31 October 1966. Subsequently, a series of rockets were produced, designated Mu-3 and Mu-4. In 1969 a suborbital test launch of the Mu-3D was conducted. The first orbital launch attempt for the Mu family, using a Mu-4S, was conducted on 25 September 1970, however the fourth stage did not ignite, and the rocket failed to reach orbit. On 16 February 1971, Tansei 1 was launched by another Mu-4S rocket. Two further Mu-4S launches took place during 1971 and 1972. The Mu-4S was replaced by the Mu-3C, was launched four times between 1974 and 1979, with three success ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
