Aug 03, 2012–Paris,France (Techreleased) –Astrium, Europe’s leading space technology company, has completed the 50th consecutive successful launch of Ariane 5, extending its existing world record for launchers currently in service.
This flight is the first to feature two new flight computers. Offering four times more memory and 10 times faster computing power, the computers enhance the launcher’s flight reliability and responsiveness.
The launch also set a new world record for geostationary transfer orbit (GTO) payload capacity of nearly 10.2 tonnes, 130 kg more than the previous record. The two satellites respectively weighed 6,100 kg and 3,300 kg, in addition to the remaining weight of the transponders and the SYLDA dual launch system, some 780 kg.
“Without this steady increase in the capacity of Ariane 5, it would not have been possible to send these two satellites into orbit in a single launch,” said a delighted Michel Freuchet, Astrium Space Transportation’s Director of Launchers. “We’re not going to stop here either. When Ariane 5 ME becomes operational in 2017, the European launcher will be capable of placing more than 12 tonnes in geostationary orbit.”
Since Astrium became the prime contractor in 2003 and thanks to investments by the company, its payload capacity has increased from an initial GTO capacity of 9.4 tonnes to 10.2 tonnes today. Moreover, Ariane 5 continues to place in low-Earth orbit the heaviest items ever sent into space, among them the International Space Station’s European Automated Transfer Vehicle, the ATV, which alone weighs more than 20 tonnes. Not only is Europe’s Ariane 5 the most reliable commercial launcher on the world market, it also has the largest payload capacity.
As with every launch, Astrium’s control centre near Paris supervised a team of 150 people who analysed flight parameters remotely from Europe. It is their job to advise, in real time, the three Astrium managers based in Kourou on the mission’s risks and chances of success. These three managers (the Ariane 5 Development Manager, Production Manager and Technical Director) have the final say in decisions relating to the flight.
“This 50th consecutive successful launch of Ariane 5 would not have been possible without the commitment of Astrium’s teams, our partners and our suppliers,” said Astrium Space Transportation CEO Alain Charmeau. “Each launch represents a new challenge requiring more than 600 inspection phases, the involvement of more than 4,500 people in 12 countries across Europe and more than a million working hours.”
