Last month, Arianespace had failed with Vega, which exploded nearly two minutes after takeoff, following an anomaly when lighting the second floor. A first failure with this European light launcher since its commissioning in 2012. Three weeks after this incident, Arianespace returns to success.
From the Guiana Space Center, an Ariane 5 rocket (ECA) took off Tuesday at 4:30 pm, Kourou time (9:30 pm, Paris time), with two 9.8 tonne telecommunications satellites on board. They have been successfully placed in a geostationary orbit. This was the third mission of the year for the European heavy launcher.
The Intelsat 39 satellite is designed " to meet the needs of broadband network operators, video providers and government customers in Africa, Asia, Europe, the Middle East and the Indian Ocean region ", says Arianespace.
On behalf of Airbus and the European Space Agency, the EDRS-C satellite is the second node of the European SpaceDataHighway network presented as the " first fiber optic network of space. "He will contribute to" improve environmental monitoring and safety services, disaster response capabilities and crisis management. "
According to Airbus, SpaceDataHighway is a 1.8 Gbps network consisting of satellites in geostationary orbit and a network of ground stations. " SpaceDataHighway's satellites can be connected by laser, at a distance of 45,000 km, to low-orbit observation satellites, intelligence drones or mission aircraft. "
For this VA249 mission, the load capacity of Ariane 5 was increased by 90 kg thanks to the extension of the hydrogen and liquid oxygen tanks of its upper stage (to increase their propellant storage capacity). . The pitcher was asked a total performance of 10,661 kg, of which 9,786 kg for both satellites.
