Guiana Space Centre
The Guiana Space Centre (french: links=no, Centre spatial guyanais; CSG), also called Europe's Spaceport, is a European spaceport to the northwest of Kourou in French Guiana, a region of France in South America. Kourou is located approximately north of the equator, at a latitude of 5°. In operation since 1968, it is suitable as a location for a spaceport, because of its equatorial location and open sea to the east. The European Space Agency (ESA), the European Union Agency for the Space Programme (EUSPA), the French space agency CNES (National Centre for Space Studies), the Space Agency of the Republic of Azerbaijan (Azercosmos) and the commercial company Arianespace conduct launches from Kourou. It was used by the ESA to send supplies to the International Space Station using the Automated Transfer Vehicle. History In 1964 Guiana was selected to become the spaceport of France, replacing France's first launch site Centre interarmées d'essais d'engins spéciaux in Hammagu ...

Ariane 5
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 inten ...

XMM-Newton
''XMM-Newton'', also known as the High Throughput X-ray Spectroscopy Mission and the X-ray Multi-Mirror Mission, is an X-ray space observatory launched by the European Space Agency in December 1999 on an Ariane 5 rocket. It is the second cornerstone mission of ESA's Horizon 2000 programme. Named after physicist and astronomer Sir Isaac Newton, the spacecraft is tasked with investigating interstellar X-ray sources, performing narrow- and broad-range spectroscopy, and performing the first simultaneous imaging of objects in both X-ray and optical ( visible and ultraviolet) wavelengths. Initially funded for two years, with a ten-year design life, the spacecraft remains in good health and has received repeated mission extensions, most recently in October 2020 and is scheduled to operate until the end of 2022. ESA plans to succeed ''XMM-Newton'' with the Advanced Telescope for High Energy Astrophysics (ATHENA), the second large mission in the Cosmic Vision 2015–2025 plan, to be laun ...

Eutelsat 28A
Eutelsat 133 West A (formerly Eurobird 1, Eutelsat 28A, and Eutelsat 33C) is a Eutelsat operated Eurobird satellite, used primarily for digital television. It was launched in March 2001, and after a short period testing at 33°E, joined Eutelsat 2F4 at 28.5°E in the Clarke Belt, just within the range of satellite dishes pointed at SES' Astra 2 satellites at 28.2° east. It moved to 33° east and joined Eutelsat 33B in July 2015. Then it was moved to 133° west. Operations The satellite has three beams. A fixed beam covers almost all of Europe as well as north-western Africa. There are also two steerable beams - the first, "S1", co-focused with the fixed beam but with a Europe-only footprint, and a second, "S2", aimed to central Europe. This beam features many transponders with low symbol rates, used for satellite news gathering. It features 24 active transponders and 12 backup transponders, all Ku band. 12 of its transponders are significantly wider (72 MHz band ...

AMC-8
AMC-8, also known as Aurora III, previously GE-8, is a C band (IEEE), C-band satellite located at 139° West, covering the United States, Canada and the Caribbean. It is owned and operated by SES World Skies, formerly SES Americom and before that SES Americom, GE Americom. The satellite provides critical telecommunications services to AT&T Alascom, which occupies most of the satellite's capacity. AMC-8 was launched in 2000 as GE-8, and replaced Satcom-C5 in March 2001. AMC-8 was used by thousands of terrestrial radio stations for network feeds using ground equipment from Starguide, X-Digital Systems, Wegener and International Datacasting.

Astra 2D
Astra 2D is one of the Astra communications satellites owned and operated by Société Européenne des Satellites (SES), and located at 28.2° East in the geostationary orbit until June 2015. It is a Hughes Space and Communications HS-376HP satellite bus, and was launched from the Centre Spatial Guyanais in December 2000 to join Astra 2A and Astra 2B at 28.2° East, where it remained for its active life. As of February 2013, Astra 2D has carried no regularly active transponders. In service While active, most of Astra 2D's transponders were used to provide television channels available on the Sky Digital satellite service to both Ireland and the United Kingdom, as well as the non-subscription service, freesat. Provision of rights-sensitive broadcasts free-to-air was made possible by the satellite's beam that was tightly focused on Ireland and the United Kingdom. However, surrounding countries had the ability to pick up the signal (dependent on suitably sized satellite di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ariane 5 Flight 501
Ariane flight V88 was the failed maiden flight of the Arianespace Ariane 5 rocket, vehicle no. 501, on 4 June 1996. It carried the Cluster spacecraft, a constellation of four European Space Agency research satellites. The launch ended in failure due to multiple errors in the software design: dead code, intended only for Ariane 4, with inadequate protection against integer overflow led to an exception handled inappropriately, halting the whole otherwise unaffected inertial navigation system. This caused the rocket to veer off its flight path 37 seconds after launch, beginning to disintegrate under high aerodynamic forces, and finally self-destructing via its automated flight termination system. The failure has become known as one of the most infamous and expensive software bugs in history. The failure resulted in a loss of more than US$370 million. Launch failure The Ariane 5 reused the code from the inertial reference platform from the Ariane 4, but the early p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
