Two of the satellites will transmit TV services to America and Australia. The third is a test platform for the Japanese space agency (Jaxa). | |
The flight from Kourou in French Guiana was the fourth mission of the year for the Ariane 5, which is operated by the Paris-based Arianespace company. | |
The ECA has the power to push payloads of 10 tonnes towards a geostationary orbit, 36,000km above the Earth. | The ECA has the power to push payloads of 10 tonnes towards a geostationary orbit, 36,000km above the Earth. |
The total payload at lift-off for this flight was just short of the maximum for the 50m-long rocket. | The total payload at lift-off for this flight was just short of the maximum for the 50m-long rocket. |
The DIRECTV 9S satellite, for the US operator DIRECTV Incorporated, was the heaviest item at 5.5 tonnes; the OPTUS D1 spacecraft, for the Australian operator OPTUS, was 2.3 tonnes at launch; and the Japanese LDREX-2 experimental reflector had a lift-off mass of 211kg. | |
The latter was mounted to the base of the Ariane 5's payload "stack" and was a scale-model intended to test the design of a large deployable antenna that will be flown on a future Jaxa mission. | |
The ECA left Kourou at 1756 local time (2056 GMT). |
