Mu (rocket Family)
The Mu, also known as M, was a series of Japanese Solid-fuel rocket, solid-fueled carrier rockets, which were launched from Uchinoura Space Center, 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-4, 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 ti ...

M-V With Astro-E Satellite
The M-V rocket, also called M-5 or Mu-5, was a Japanese solid-fuel rocket designed to launch Science, scientific satellites. It was a member of the Mu (rocket family), Mu family of rockets. The Institute of Space and Astronautical Science (ISAS) began developing the M-V in 1990 at a cost of 15 billion Japanese yen, yen. It has three stages and is high, in diameter, and weighs about . It was capable of launching a satellite weighing into an orbit as high as . The first M-V rocket launched the HALCA radio astronomy satellite in 1997, and the second the Nozomi (spacecraft), Nozomi Mars explorer in July 1998. The third rocket attempted to launch the ASTRO-E, Astro-E X-ray satellite on 10 February 2000 but failed. ISAS recovered from this setback and launched Hayabusa to 25143 Itokawa in 2003. The following M-V launch was the scientific Suzaku (satellite), Astro-E2 satellite, a replacement for Astro-E, which took place on 10 July 2005. The final launch was that of the Hinode (sate ...

Orbital Inclination
Orbital inclination measures the tilt of an object's orbit around a celestial body. It is expressed as the angle between a reference plane and the orbital plane or axis of direction of the orbiting object. For a satellite orbiting the Earth directly above the Equator, the plane of the satellite's orbit is the same as the Earth's equatorial plane, and the satellite's orbital inclination is 0°. The general case for a circular orbit is that it is tilted, spending half an orbit over the northern hemisphere and half over the southern. If the orbit swung between 20° north latitude and 20° south latitude, then its orbital inclination would be 20°. Orbits The inclination is one of the six orbital elements describing the shape and orientation of a celestial orbit. It is the angle between the orbital plane and the plane of reference, normally stated in degrees. For a satellite orbiting a planet, the plane of reference is usually the plane containing the planet's equator. For pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hinotori (satellite)
Hinotori, also known as ASTRO-A before launch, was a Japanese X-ray astronomy satellite. It was developed by the Institute of Space and Astronautical Science (ISAS). Its primary mission was to study of solar flares emanating from the Sun during the solar maximum. It was launched successfully on February 21, 1981 using a M-3S rocket as the vehicle from 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 Uchino ... (known at the time as Kagoshima). After the start of normal operation, it observed a large solar flare and, a month later, succeeded in observing 41 flares of many sizes from the Sun. It reentered the atmosphere on July 11, 1991.ISAS "Solar Observation HINOTORI (ASTRO-A)" retrieved 2014-12-23. The name Hinotori is the Japanese word for Phoenix. Instruments * ...

Tansei 4
was the second Japanese artificial satellite which was put into orbit, after the country's first 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 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 ins ... (UTokyo).

High Earth Orbit
A high Earth orbit is a geocentric orbit with an apsis, apogee farther than that of the geosynchronous orbit, which is height above mean sea level, away from Earth. In this article, the non-standard abbreviation of ''HEO'' is used for high Earth orbit. The development of HEO technology has had a significant impact on space exploration and has paved the way for future of space exploration, future missions to deep space exploration, deep space. The ability to place satellites in HEO has allowed scientists to make groundbreaking discoveries in astronomy and Earth science, while also enabling international communication, global communication and navigation systems. The Moon's Hill sphere is entered at a distance to the Moon of , lunar orbits until a distance of are unstable due to Earth's gravitational reach.

Taiyo (satellite)
Solar Radiation and Thermospheric Satellite (SRATS), also knows as Taiyo ("Sun" in Japanese) or Shinsei-3, was a space probe developed by the Institute of Space and Astronautical Science (ISAS) at the University of Tokyo. The probe was launched on February 24, 1975, from Kagoshima Space Center by M-3C-2 rocket. Its mission was focused on upper atmospheric physics, X-ray and UV solar radiation, and the Earth's ionosphere. Taiyo completed its mission before re-entering Earth's atmosphere on June 29, 1980. The satellite had a shape of octagonal cylinder (or prism), weighing 86 kg. It orbited the Earth in an elliptical orbit with a periapsis of 260 km and an apoapsis An apsis (; ) is the farthest or nearest point in the orbit of a planetary body about its primary body. The line of apsides (also called apse line, or major axis of the orbit) is the line connecting the two extreme values. Apsides perta ... of 3,140 km, at a 32-degree inclination. The satellite' ...

Medium Earth Orbit
A medium Earth orbit (MEO) is an geocentric orbit, Earth-centered orbit with an altitude above a low Earth orbit (LEO) and below a high Earth orbit (HEO) – between above sea level.''Catalog of Earth Satellite Orbits'' NASA Earth Observatory. 4 September 2009. Accessed 2 May 2021. The boundary between MEO and LEO is an arbitrary altitude chosen by accepted convention, whereas the boundary between MEO and HEO is the particular altitude of a geosynchronous orbit, in which a satellite takes 24 hours to circle the Earth, the same period as the Earth’s own rotation. All satellites in MEO have an orbital period of less than 24 hours, with the minimum period (for a circular orbit at the lowest MEO altitude) about 2 hours. Satellites in MEO or ...
