Eutelsat W7 atop Proton-M/Briz-M on November 24, 2009
   Launch site: Baikonur Launch date: November 24, 2009 The launch time is: 19 : 19 : 10 Baikonur 24.11.2009 17 : 19 : 10 Moscow Local 24.11.2009 14 : 19 : 10 UTC Nov 24, 2009 9 : 19 : 10 a.m. EST Nov 24, 2009 Payload: W7 Broadcasting Satellite The W7 mission will be the 8th Proton launch of 2009 and the 349th Proton flight overall. Spacecraft: W7  Manufacturer: Thales Alenia Space  The W7 is a new communications satellite of Eutelsat Communications built by Thales Alenia Space. The company's newest and most powerful spacecraft to date will be co-located with W4 at 36 degrees East to more than double resources at one of Eutelsat's fastest-growing neighborhoods, with more than 450 TV channels broadcast to those regions as of late 2009. Through a configuration of up to 70 transponders connected to five high-performance fixed and steerable beams, W7 will provide coverage of Russia and sub-Saharan Africa for digital broadcasting services including pay-TV, and add significant resources and flexibility for expanding video and telecommunications markets in Europe, Africa, the Middle East and Central Asia. In addition to video applications, W7 offers potential for data and voice solutions using small ground terminals, in particular for the oil and gas sector in Russia, Central Asia and West Africa. The W7 satellite is based on the Spacebus 4000 C4 platform with a launch mass of approximately 5600 kg and has a 15-year life expectancy. W7 is the second satellite after W2A to be built by Thales for Eutelsat. The spacecraft will replace Eutelsat's SESAT 1 satellite, launched on a Proton in early 2000. It is expected to enter commercial service in January 2010. W7's launch marks the latest step in Eutelsat's far-reaching investment program of new satellites designed to expand, renew and secure its in-orbit resources. Four further satellites will be orbited by the end of 2011 (W3B, KA-SAT, W3C and Atlantic Bird 7).

W7 Ascent Profile The Proton-M three stages place the ascent unit (AU), which consists of a Breeze-M upper stage, adapter system and W7, into a 51.5 inclination suborbital trajectory. Proton-M powered flight lasts 581 seconds. The AU powered flight begins at the moment of the third stage separation.  Breeze-M Powered Flight The upper stage follows a five-burn injection profile. The Breeze-M powered flight lasts 33,120 seconds (9 hrs 12 min).   The vehicle's reliability statistics according to http://www.spacelaunchreport.com/reliability2009.txt: Code:

According to http://www.itar-tass.com/level2.html...8740&PageNum=0,
the launch has been postponed for 1 day till November, 24. The cause for the delay is not specified yet. ---------- Post added at 12:37 ---------- Previous post was at 10:29 ---------- The new launch time is: 19 : 19 : 10 Baikonur 24.11.2009 17 : 19 : 10 Moscow Local 24.11.2009 14 : 19 : 10 UTC Nov 24, 2009 9 : 19 : 10 a.m. EST Nov 24, 2009 ---------- Post added at 13:20 ---------- Previous post was at 12:37 ---------- Attention, Kazakh high hat downrange!

---------- Post added at 20:37 ---------- Previous post was at 13:20 ---------- http://www.kt.kz/index.php?lang=rus&...ter=1153503740 Summary: Roscosmos calls the delay with W7 satellite launch a misapprehension caused by delay on getting a launch clearance from Kazakhstan. Roscosmos officials confirm all the necessary documents had been agreed upon and hope that it's going to be dissolved as soon as possible and the launch will be commenced on the backup date November 24, 2009. On other hand, Kazcosmos informs that W7 launch has not been provided for by this year's agreed launch schedule. According to them, Roscosmos submitted the launch permission request to Kazakh Prime Minister's Chancellary as late as on September 26, 2009. To quote Kazcosmos' message, "Russian side was duly informed that decision taking process within Government of Kazakhstan takes considerable time and is not over yet at the moment". ---------- Post added at 20:38 ---------- Previous post was at 20:37 ---------- Kazcosmos website link with the official message: http://www.kazcosmos.kz/?m=news&lng=...&act=show_news |

Political friction delayed the launch
 ? That's the first time I've ever heard about something like that.
