Videos Eutelsat W7 atop Proton-M/Briz-M on November 24, 2009

Launch site:
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).

Attention, Kazakh high hat downrange!

23-11-2009 Information on W7 launch for Media.

The launch of communication spacecraft Eutelsat W7 from Baikonur which was planned on today at 17.19 Moscow time, is postponed due to circumstances beyond Russian responsibility. According to the Russian Federal Space Agency, all documents were submitted to Kazcosmos approval in advance and corresponding prelaunch arrangements were undertaken. The areas where Proton-M stages were to collapse were repeatedly coordinated with Kazcosmos.

It is not the first case when a spacecraft lift-off is under the threat of frustration due to circumstances beyond Russian responsibility.

Roscosmos Press Office

---------- Post added at 20:37 ---------- Previous post was at 13:20 ----------



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".

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

Today at Baikonur, State Commission have finished its session during which the questions of launch readiness of Proton-M vehicle with W7 satellite were considered. The State Commission members have issued a clearance for fueling the vehicle and proceeding with launch operations.

The launch is planned for today, November 24, at 17:19 Moscow Time.

It's not quite clear yet, what exactly is this: "Kazakhstan reasoned", "Kazakhstan ignored" or "An expedite money transfer is on its way". We have to wait and see.

W7 Mission Successful!

Posted by ILS Communications Team, 6:30 p.m. EST on 24 November 2009

We have had a successful mission with the Proton M Breeze M rocket, carrying the W7 satellite built by Thales Alenia Space for Eutelsat. We have had confirmation that the satellite separated from the vehicle on schedule at 6:30 p.m. EST, or 04:34 GMT, 9 hours and 12 minutes after liftoff.

Everything occurred as planned with ignition, shutdown and separation of the Protons first three stages. Then the Breeze M upper stage with the satellite continued the mission, igniting five times, and then releasing the satellite into transfer orbit.

Paris, 25 November 2009

The W7 satellite of Eutelsat Communications (Euronext Paris: ETL) has been successfully lofted into orbit by a Proton Breeze M rocket supplied by ILS. Lift-off of Eutelsats 5.6 tonne communications satellite took place on Tuesday 24 November at 14.19 GMT (15.19 CET). After a 9-hour 12-minute flight, the launcher released W7 into geosynchronous transfer orbit
at 23.31 GMT (00.31 CET).

Commenting after successful spacecraft separation, Eutelsat CEO, Michel de Rosen said: We are delighted to announce that our W7 satellite is on its way to 36 East, and we thank ILS and Khrunichev for responding to our requirements for quality, efficient and timely service. This new satellite will be a key pillar for our business development at a well established neighbourhood, addressing dynamic markets with clear potential for sustained growth. W7 will support expansion of pay-TV platforms in Russia and across Africa. It will also give us headroom to expand telecoms and data activity in a vast region embracing Europe, the Middle East, Africa and Central Asia.

With three new satellites having already entered into commercial service in 2009 - HOT BIRD 9, ATLANTIC BIRD 4A and W2A - todays launch also represents a new step forward in Eutelsats significant in-orbit expansion programme. Four additional satellites will follow W7 into orbit by the end of 2011 to equip us with the resources, flexibility and reach we need to capture further business opportunities in video, telecom and broadband markets.

Based on the Spacebus 4000C4 design, W7 was built for Eutelsat by Thales Alenia Space. The satellites apogee motor will be fired three times over the coming five days to circularise its orbit and solar panels and antennas will be fully deployed by the beginning of next week. After an extensive round of in-orbit tests, the satellite will be commercially available at 36 degrees East in early January 2010.

Message of Press Office of Space Agency of Kazakhstan


24.11.2009 Russian Proton-M rocket launch

Government of Republic of Kazakhstan has approved the change into Plan of Space Launches from Baikonur Cosmodrome, including the launch of Russian Proton-M launch vehicle with European W7 satellite on board. The launch was commenced on November 24, 2009 at 17 : 19 Moscow Time.

The postponement of the launch from 23rd to 24th (the backup date) was caused by the unscheduled nature of this launch. It was not provided for by the earlier agreed upon plan of Space Launched for year 2009 and was envisaged by Republic of Kazakhstan exclusively to satisfy the Russian side's request.


National Space Agency of Kazakhstan believes that many recent positive decisions of similar nature in favour of Russia proves adherence of Kazakhstan to the principles of Kazakh-Russian strategic partnership.
