Heliophysics
Heliophysics (from the prefix " helio", from Attic Greek ''hḗlios'', meaning Sun, and the noun "physics": the science of matter and energy and their interactions) is the physics of the Sun and its connection with the Solar System. NASA defines heliophysics as "(1) the comprehensive new term for the science of the Sun - Solar System Connection, (2) the exploration, discovery, and understanding of Earth's space environment, and (3) the system science that unites all of the linked phenomena in the region of the cosmos influenced by a star like our Sun." Heliophysics concentrates on the Sun's effects on Earth and other bodies within the Solar System, as well as the changing conditions in space. It is primarily concerned with the magnetosphere, ionosphere, thermosphere, mesosphere, and upper atmosphere of the Earth and other planets. Heliophysics combines the science of the Sun, corona, heliosphere and geospace, and encompasses a wide variety of astronomical phenomena, including ...

Equator-S
The ''Equator-S'' satellite was a spacecraft constructed by the Max Planck Institute for Extraterrestrial Physics for the International Solar-Terrestrial Physics Science Initiative. It was operational between 2 December 1997 and 1 May 1998. Description Equator-S was a low-cost mission, launched with the intention to study the Earth's magnetosphere around the equator at heights lower than 67,000 km. It was located in a near-equatorial orbit, which gave Equator-S the ability to make unique observations about the interaction between the magnetosphere and interplanetary space. Equator-S had a very high spin rate and was launched on an Ariane 4 rocket on 2 December 1997. The mission ended earlier than expected, having initially been intended to have a lifetime of two years. The mission was terminated on 1 May 1998 after the failure of the onboard processor system.

Hinode (satellite)
Hinode (; ja, ひので, , Sunrise), formerly Solar-B, is a Japan Aerospace Exploration Agency Solar mission with United States and United Kingdom collaboration. It is the follow-up to the Yohkoh (Solar-A) mission and it was launched on the final flight of the M-V rocket from Uchinoura Space Center, Japan on 22 September 2006 at 21:36 UTC (23 September, 06:36 JST). Initial orbit was perigee height 280 km, apogee height 686 km, inclination 98.3 degrees. Then the satellite maneuvered to the quasi-circular sun-synchronous orbit over the day/night terminator, which allows near-continuous observation of the Sun. On 28 October 2006, the probe's instruments captured their first images. The data from Hinode are being downloaded to the Norwegian, terrestrial Svalsat station, operated by ''Kongsberg'' a few kilometres west of Longyearbyen, Svalbard. From there, data is transmitted by Telenor through a fibre-optic network to mainland Norway at Harstad, and on to data users ...

Helios (spacecraft)
''Helios-A'' and ''Helios-B'' (after launch renamed ' and ') are a pair of probes that were launched into heliocentric orbit to study solar processes. As a joint venture between German Aerospace Center (DLR) and NASA, the probes were launched from Cape Canaveral Air Force Station, Florida, on December10, 1974, and January15, 1976, respectively. The Helios project set a maximum speed record for spacecraft of . ''Helios-B'' performed the closest flyby of the Sun of any spacecraft until that time. The probes are no longer functional, but as of 2022 remain in elliptical orbits around the Sun. Construction The Helios project was a joint venture of West Germany's space agency DLR (70 percent share) and NASA (30 percent share). As built by the main contractor, Messerschmitt-Bölkow-Blohm, they were the first space probes built outside the United States and the Soviet Union to leave Earth orbit. Structure The two ''Helios'' probes look similar. ''Helios-A'' has a mass of , an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SES-14
SES-14 is a geostationary communications satellite operated by SES S.A. at 47.5° West, replaces NSS-806, and designed and manufactured by Airbus Defence and Space. The satellite launched on 25 January 2018 at 22:20 UTC along with the Global-scale Observations of the Limb and Disk (GOLD) instrument from NASA. It has a mass of and has a design life of at least 15 years. Launch The launch of SES-14 on 25 January 2018 by an Ariane 5 ECA VA241 suffered an anomaly that resulted in a higher inclination than planned but later recovered. About 9 minutes and 28 seconds after launch, a telemetry loss occurred between the launch vehicle and the ground controllers. As confirmed about 1 hour and 20 minutes after launch both satellites were successfully separated from the upper stage and were in contact with their respective ground controllers, but that their orbital inclinations were incorrect as the guidance systems might have been compromised. Therefore, both satellites conducted orbi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Geotail
Geotail was a satellite that observed the Earth's magnetosphere. It was developed by Japan's ISAS in association with the United States' NASA, and was launched by a Delta II rocket on 24 July 1992 from Cape Canaveral Air Force Station. The primary purpose of this mission is to study the structure and dynamics of the tail region of the magnetosphere with a comprehensive set of scientific instruments. For this purpose, the orbit has been designed to cover the magnetotail over a wide range of distances: to from the earth. This orbit also allowed it to study the boundary region of the magnetosphere as it skims the magnetopause at perigees. In the first two years the double lunar swing-by technique was used to keep apogees in the distant magnetotail. This involved 14 lunar flybys. In 1993 the computer that controls the Low Energy Particles experiment locked up. Attempts to reset it failed. This problem was solved by changing the trajectory of the craft during a lunar flyby that too ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geostationary Operational Environmental Satellite
The Geostationary Operational Environmental Satellite (GOES), operated by the United States' National Oceanic and Atmospheric Administration (NOAA)'s National Environmental Satellite, Data, and Information Service division, supports weather forecasting, severe storm tracking, and meteorology research.
