ЦитироватьIn keeping with the CNES/CSG safety regulations, the launch of Arianespace Flight 221 has been postponed due to unfavourable weather conditions over the launch pad in Kourou, French Guiana. Flight 221 will place into geostationary transfer orbit the DIRECTV-14 and GSAT-16 telecommunications satellites.Another launch date will be decided depending on the evolution of the weather conditions in Kourou.

ЦитироватьKourou, December 6, 2014In light of the improvement in the weather conditions over the Guiana Space Center, Arianespace has decided to restart the countdown for Ariane Flight VA221. This mission will place two satellites into orbit: DIRECTV-14 and GSAT-16.Llift-off of the Ariane 5 ECA launcher is now set for the night of Saturday, December 6, as early as possible in the following launch window:From 5:40 p.m. to 6:49 p.m., local time in Kourou, French GuianaFrom 3:40 p.m. to 4:49 p.m. in Washington D.C.From 8:40 p.m. to 9:49 p.m. UTC,From 9:40 p.m. to 10:49 p.m. in Paris,From 2:10 a.m. to 3:19 a.m. in Bangalore, on Sunday, December 7.
Цитировать Ariane 5 delivers DIRECTV-14 and GSAT-16 to orbit on Arianespace's latest mission success December 6, 2014 – Ariane Flight VA221Telecommunications satellites for two long-standing Arianespace customers were launched today on the company's sixth Ariane 5 flight in 2014, extending the heavy-lift workhorse's string of consecutive successes to 63. Delivering a total payload lift performance of approximately 10,200 kg., the mission – designated Flight VA221 in Arianespace's numbering system – lofted DIRECTV-14 for operator DIRECTV, along with the Indian Space Research Organisation's (ISRO) GSAT-16. The DIRECTV-14 spacecraft was deployed first in the flight sequence, separating from Ariane 5 nearly 28 minutes after liftoff, followed four minutes later by its GSAT-16 co-passenger. A launch for two long-time customers Today's heavy-lift success on Flight VA221 continues long relationships of trust between Arianespace and each of the mission's two customers. The company lofted its first DIRECTV satellite in 1993 (DIRECTV-11 using an Ariane 44L version), and in total has orbited seven spacecraft for this operator – including DIRECTV-14, which also represents the 46th SSL-built (Space Systems/Loral) payload to be launched by Arianespace. To operate from an orbital location of 99 deg. West, DIRECTV-14 is a 20-kilowatt class Ka-band and reverse-band digital broadcast satellite that will deliver Ultra HD and other new consumer services for DIRECTV. It is based on the SSL 1300 spacecraft platform with a liftoff mass of approximately 6,300 kg., and is to provide service for users across the U.S. (including Hawaii and Alaska) and Puerto Rico.ISRO has been an Arianespace customer for 33 years, beginning with the Ariane 1 launch of its APPLE spacecraft in 1981. Since then, 17 more of the Indian space agency's payloads have been launched – capped off with the successful deployment of GSAT-16 today. With a liftoff mass estimated at 3,180 kg., GSAT-16 carries Ku- and C-band transponders to further augment communication services across India – operating from an orbital position of 55 deg. East. Flight VA221 also pushed Arianespace "over the top" for a record combined payload mass orbited from French Guiana in a single year: 74.3 tons – eclipsing the previous mark set by the company in 2012. Arianespace's next mission will be the December 18 flight of a medium-lift Soyuz from French Guiana, which will deploy the next four connectivity satellites for operator O3b Networks. Ariane 5 is shown ready for its liftoff at the Spaceport in French Guiana.
