Arianespace... Double Departures (Launch)




[SatNews] A heavy-lift Ariane 5 successfully orbited two satellite payloads on Friday, April 22nd... 

The two satellites will supply telecommunications services for two new customers who join the growing list ofArianespace commercial launch services users. In a flight conducted from the Spaceport in French Guiana, the Ariane 5 deployed the Intelsat New Dawn, which was built for the new joint venture of Intelsat and Convergence Partners, as well as Yahsat Y1A, the first satellite to be operated by the United Arab Emirates’ Al Yah Satellite Communications Company. Adding to this mission’s milestones was the lift performance record for Ariane 5: delivering a total mass of10,050 kg. to geostationary transfer orbit, of which 8,956 kg. was the combined weight of its two satellite payloads.

Lifting off on time at 6:37 p.m on the 22nd. in French Guiana, the Ariane 5 climbed through a partial cloud cover at sunset, and continued its downrange flight in clear skies. This allowed a direct view of the separation for Ariane 5’s two solid propellant boosters at an altitude of 66.5 kilometers, followed by the payload fairing’s jettison at a 105-kilometer altitude. It marked another of Ariane 5’s highly accurate flights, with the following estimated orbital parameters at the injection of its cryogenic upper stage:
