Tansei 1
was the second Japanese artificial satellite which was put into orbit, after the country's first satellite Ohsumi (satellite), Ohsumi. The satellite was sent into orbit on 16 February 1971. Just like Ohsumi, the launch was a project by the Institute of Space and Astronautical Science at the University of Tokyo (UTokyo). The name of the satellite means "light blue", which is the school colour of UTokyo. Three more satellites with the same name were subsequently launched by the university. The last of them was launched on 17 February 1980. References [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Institute Of Space And Astronautical Science
, or 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. Established as part of the University of Tokyo in 1964, the institute spun off from the university to come under direct purview of the Ministry of Education. 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 ) 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 ...

University Of Tokyo
The University of Tokyo (, abbreviated as in Japanese and UTokyo in English) is a public research university in Bunkyō, Tokyo, Japan. Founded in 1877 as the nation's first modern university by the merger of several pre-westernisation era institutions, its direct precursors include the '' Tenmongata'', founded in 1684, and the Shōheizaka Institute. Although established under its current name, the university was renamed in 1886 and was further retitled to distinguish it from other Imperial Universities established later. It served under this name until the official dissolution of the Empire of Japan in 1947, when it reverted to its original name. Today, the university consists of 10 faculties, 15 graduate schools, and 11 affiliated research institutes. As of 2023, it has a total of 13,974 undergraduate students and 14,258 graduate students. The majority of the university's educational and research facilities are concentrated within its three main Tokyo campuses: Hongō, ...

Satellites Formerly Orbiting Earth
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 constellations. Be ...

Spacecraft Launched In 1971
A spacecraft is a vehicle that is designed to fly and operate in outer space. Spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit (space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific research are space prob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
