<br /><br />Another dual launch for Ariane 5
30 October 2009
Last night, an Ariane 5 ECA launcher lifted off from Europe’s Spaceport in French Guiana on a journey to place two telecommunications satellites, NSS-12 and Thor 6, into geostationary transfer orbits. Flight V192 was the sixth Ariane 5 launch of 2009 and the fourth dual-payload mission.
Liftoff of the 48th Ariane 5 mission took place at the start of the launch window: 21:00 CET (20:00 UTC; 17:00 French Guiana). The target injection orbit had a perigee altitude of 250 km, an apogee altitude at injection of 35 786 km and an inclination of 6º. The satellites were accurately injected into their transfer orbits about 27 and 31 minutes after liftoff, respectively.
NSS-12 will be located at 57°E and provide direct-to-home coverage using four regional Ku-band spot beams covering the Middle East and Europe, Central and South Asia and, for the first time, East Africa. High-capacity, high-power C-band hemispheric beams will serve Europe, Africa (including Mauritius) and the Middle East, as well as an area stretching across Asia to Australia. A powerful C-band global beam will reach from the United Kingdom to the Far East.
Thor 6 will be located at 1°W and deliver high-power, direct-to-home television services using 36 Ku-band transponders, 16 of which will serve the Nordic countries. The other 20 transponders will provide capacity for the growing broadcasting demands across Central and Eastern Europe.
The payload mass for this launch was 9462 kg; the satellite masses totalled 8671 kg, with payload adapters and dispensers making up the additional 791 kg.
Liftoff of flight V192
Arianespace and Europe’s Spaceport are planning seven Ariane launches during 2009, maintaining the heavy-lift vehicle’s flight rate. The ability to sustain high launch rates has already been demonstrated: during the 12-month period from August 2007 to August 2008, there were nine launches (V177 – V185).
Initial construction of the Ariane 5 GS launcher for the seventh flight has been completed and the vehicle stands ready in the Launcher Integration Building (Bâtiment d’Intégration Lanceur; BIL) to be transferred to the Final Assembly Building (Bâtiment d’Assemblage Final; BAF) now it has been vacated by the rollout of V192.
Flight timeline
The Ariane 5’s cryogenic, liquid-propellant main engine was ignited first. Seven seconds later, the solid-propellant boosters were also fired, and the vehicle lifted off a fraction of a second later.
The solid boosters were jettisoned 2 min 21 sec after main engine ignition, and the fairing protecting the payload during the climb through Earth’s atmosphere was discarded at 3 min 9 sec. The launcher’s main engine was shut down at 8 min 52 sec; six seconds later, the main cryogenic stage separated from the upper stage and its payload.
Four seconds after main stage separation, the engine of the cryogenic upper stage was ignited to continue the journey. The engine was shut down at 24 min 45 sec into the flight, at which point the vehicle was travelling at 9400 m/s (33 840 km/h) at an altitude of 600 km. The conditions for geostationary transfer orbit injection had been achieved.
At 26 min 36 sec after main engine ignition, NSS-12 separated from the upper stage, followed by Thor 6 at 31 min 14 sec. Ariane 5’s flight operations were completed 49 min 28 sec after main engine ignition.

看吧，想当年阿里安5自毁很多人看在眼里拔不出来，现在已经完成第48次发射了。本次发射是年内第六次发射，以及第四次双星发射。
实际上10月份，阿里安5执行了两次发射。第一次发射是10月1日，大家估计都在国庆兴头上，所以没有关注到。第二次是在月底的10月29日，两次发射都是双星，一个月里面两箭四星，这个实力TG还是好好想想吧。
TG航天发射的密度，美，俄，中，欧4个里面，是最低的了吧，越低越没机会刷经验。
总是一穷二白的时候拼命追，稍微赶上点就歇菜，变成龙团长那句：命都不要，只要安逸。

俺知道呀··两个通信和转播卫星嘛··下个月2号还有一颗Proba -2 水环境检测的··没多大观赏价值的说·
TG是怎么想的就不好说鸟···俺最不喜欢看TG的发射···

除非是有类似GPS之类的星座要搞，否则一箭双/多星技术并不一定被市场看好。
