Arianespace will Launch the Skynet 5A and 5B Military Satcoms  
 
 
(Source: Arianespace; issued Jan. 4, 2005)
 
 
 EVRY, France --- Colin Paynter, Managing Director of EADS Astrium Ltd., and Jean-Yves Le Gall, CEO of Arianespace, today announced the signature of two launch contracts, for the Skynet 5A and 5B satellites.  
 
These two satellites will be boosted into geostationary transfer orbit by Ariane 5 launchers from the Guiana Space Center, Europe's Spaceport in Kourou, French Guiana. Launches are scheduled for the second half of 2006 and the second half of 2007.  
 
Skynet 5A and 5B will be launched by Arianespace on behalf of EADS Astrium, which in turn will deliver the satellites in orbit to the commercial organisation Paradigm Secure Communications. Paradigm is contracted to provide secure communications services for the British armed forces, NATO and a number of other countries.  
 
The Skynet 5 satellites, built by EADS Astrium, will weigh approximately 4,700 kilograms at launch.  
 
Europe's Ariane launcher has already orbited the Skynet 4B, 4C, 4E and 4F satellites for the British Ministry of Defense.  
 
The Ariane 5 launcher is key to the development of a common European defense and security policy, for which the space segment is essential. Skynet 5A and 5B are the 24th and 25th military payloads entrusted to the European launch vehicle. (ends)  
 
 
 
 Arianespace to Orbit Two Pleiades Satellites  
 
 
(Source: Arianespace; issued Jan. 4, 2005)
 
 
 EVRY, France --- Two Pleiades Earth observation satellites are to be launched from the Guiana Space Center in Kourou, French Guiana under terms of a contract awarded to Arianespace by the CNES French space agency.  
 
Both Pleiades spacecraft will be placed in heliosynchronous orbit by Soyuz launchers - with the initial satellite orbited in 2008, followed by the second in 2009.  
 
The Pleiades satellites comprise the high-resolution optical imaging component in the Franco-Italian Orfeo system, for which Italy is supplying the radar component. These satellites will perform both civil and military missions, providing continuity with the services available via the Spot Earth observation spacecraft.  
 
EADS Astrium is prime contractor and platform manufacturer for the Pleiades satellites, which will weigh about one metric ton each. Alcatel Space will supply the high-resolution instruments and image telemetry systems. The size, image resolution, orbital agility and ground transmission capabilities of the Pléiades satellites represent a significant technological advance in Earth observation. (ends)  
 
 
 
 Arianespace to Launch the Corot Satellite  
 
 
(Source: Arianespace; issued Jan. 4, 2005)
 
 
 EVRY, France --- France's CNES space agency has awarded Arianespace a launch contract for the Corot astronomical satellite, which will be orbited in mid-2006 from Baikonur Cosmodrome on the Soyuz 2-1b launch vehicle's maiden flight.  
 
Corot will be an extremely capable space observatory, and is designed to study stars and search for new planets. Weighing 630 kg. at launch, the satellite will be the payload for the initial mission of Soyuz 2-1b - the Soyuz version that subsequently is to be operated from the Guiana Space Center (CSG). This launch is part of the Guiana Space Center's Soyuz program, and it will be executed under the responsibility of Arianespace. For the mission's launch operations, Arianespace will draw on the expertise of Starsem - which has performed commercial Soyuz flights from Baikonur Cosmodrome.  
 
This scientific mission will mark a new milestone in astronomy by carrying out two missions: the study of internal structure of stars, and the detection of plants outside our solar system.  
 
Corot uses the Proteus multimission platform built by Alcatel Space. The satellite will be placed into a polar orbit at an altitude of 850 kilometers.

Giro mesmo seria ver a agência espacial europeia por o primeiro homem, europeu, em Marte  :wink:  Melhor mesmo era se fosse Português.
