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] |

Ariane 5 ECA
Ariane 5 is a European heavy-lift space launch vehicle developed and operated by Arianespace for the European Space Agency (ESA). It is launched from the Centre Spatial Guyanais (CSG) in French Guiana. It has been used to deliver payloads into geostationary transfer orbit (GTO) or low Earth orbit (LEO). The launch vehicle had a streak of 82 consecutive successful launches between 9 April 2003 and 12 December 2017. Since 2014, Ariane 6, a direct successor system, is in development. The system was designed as an expendable launch system by the ''Centre national d'études spatiales'' (CNES), the French government's space agency, in cooperation with various European partners. Despite not being a direct derivative of its predecessor launch vehicle program, it is classified as part of the Ariane rocket family. ArianeGroup is the prime contractor for the manufacturing of the vehicles, leading a multi-country consortium of other European contractors. Ariane 5 was originally intended t ...

Global-scale Observations Of The Limb And Disk
Global-scale Observations of the Limb and Disk (GOLD) is a heliophysics Mission of Opportunity (MOU) for NASA's Explorers program. Led by Richard Eastes at the Laboratory for Atmospheric and Space Physics, which is located at the University of Colorado Boulder, ''GOLD'' mission is to image the boundary between Earth and space in order to answer questions about the effects of solar and atmospheric variability of Earth's space weather. ''GOLD'' was one of 11 proposals selected, of the 42 submitted, for further study in September 2011. On 12 April 2013, NASA announced that ''GOLD'', along with the Ionospheric Connection Explorer (''ICON''), had been selected for flight in 2017. GOLD, along with its commercial host satellite SES-14, launched on 25 January 2018. Mission concept and history ''GOLD'' is intended to perform a two-year mission imaging Earth's thermosphere and ionosphere from geostationary orbit. ''GOLD'' is a two-channel far-ultraviolet (FUV) imaging spectrograph buil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NSS-806
NSS-806 (New Skies Satellite 806), before Intelsat 806, is a communications satellite originally operated by Intelsat. Launched in 1998 it was operated in geostationary orbit at a longitude of 47 degrees west for around 15 years. It is currently located in the orbital position of 47.5 degrees west longitude, was initially operated by Intelsat, orbited at 40.5 degrees west, and was purchased by SES World Skies (a subsidiary of SES). Satellite NSS-806 is equipped with 28 transponders in C band and 3 in Ku band, making transmissions for the Americas and parts of Europe. In order to receive the signal it requires a monofocal antenna (LNBF antenna in the center), a LNBF for C band (5150 MHz) and a digital receiver compatible with C band. The NSS-806 emits its signal in circular polarization. Launch The launch of NSS-806 made use of an Atlas II rocket flying from Cape Canaveral Air Force Station, Florida, United States. The launch took place at 00:16 UTC on February 28, 1998, wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eurostar (satellite Bus)
Eurostar is a satellite bus made by Airbus Defence and Space (formerly Astrium, and before 1994, British Aerospace, and Matra Marconi Space (the former Marconi Space having been merged with Matra's former "Matra Espace" division) which has been used for a series of spacecraft providing telecommunications services in geosynchronous orbit (GEO). More than 70 Eurostar satellites have been ordered to date, of which more than 55 have been successfully launched since October 1990 and have proven highly reliable in operational service. In December 2013, the Eurostar satellites accumulated 500 years of successful operations in orbit. The Eurostar spacecraft series is designed for a variety of telecommunications needs including fixed services and broadcast, mobile services, broadband and secured communications. Development Eurostar was designed in the mid 1980s jointly by Matra Marconi Space and BAe (now integrated within Airbus Defence and Space) to Inmarsat specifications, for a market whi ...

Falcon 9
Falcon 9 is a partially reusable medium lift launch vehicle that can carry cargo and crew into Earth orbit, produced by American aerospace company SpaceX. The rocket has two stages. The first (booster) stage carries the second stage and payload to a certain altitude, after which the second stage lifts the payload to its ultimate destination. The rocket evolved through several versions. V1.0 flew from 2010–2013, V1.1 flew from 2013–2016, while V1.2 Full Thrust first launched in 2015, encompassing the Block 5 variant, flying since May 2018. The booster is capable of landing vertically to facilitate reuse. This feat was first achieved on flight 20 in December 2015. Since then, SpaceX has successfully landed boosters over 100 times. Individual boosters have flown as many as 15 flights. Both stages are powered by SpaceX Merlin engines, using cryogenic liquid oxygen and rocket-grade kerosene (RP-1) as propellants. The heaviest payloads flown to geostationary transfer or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Launch Vehicle
A launch vehicle or carrier rocket is a rocket designed to carry a payload (spacecraft or satellites) from the Earth's surface to outer space. Most launch vehicles operate from a launch pad, launch pads, supported by a missile launch control center, launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to large operating costs. An orbital spaceflight, orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital spaceflight, Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles are multistage rockets which use chemical propellants such as Solid-propellant rocket, solid fuel, liquid hydrogen, kerosene, liquid oxygen, or Hypergolic propellants.
