Still nothing from ILS. Any other routes for confirmation?
The launch of a spacecraft "Yamal-402"12/09/2012 ::December 9 at the launch of the spacecraft (SC) "Yamal-402" to the target orbit spacecraft separation occurred at 4 minutes before the estimated time.Currently, the spacecraft captured a management basis for specifying the schemes of his propel spacecraft to the point of standing with subsequent commissioning.Press Service of the Russian Federal Space Agency
Roscosmos isses the following info (automatic translation from russian):QuoteThe launch of a spacecraft "Yamal-402"12/09/2012 ::December 9 at the launch of the spacecraft (SC) "Yamal-402" to the target orbit spacecraft separation occurred at 4 minutes before the estimated time.Currently, the spacecraft captured a management basis for specifying the schemes of his propel spacecraft to the point of standing with subsequent commissioning.Press Service of the Russian Federal Space Agency
Note: Yamal 402 is equipped with an S400 Propulsion System for apogee burns and larger orbit maintenance maneuvers. The S400 series are bi-propellant engines using Monomethylhydrazine and Mixed Oxides of Nitrogen as propellants. Depending on the version used, S400 provides 420 to 425 Newtons of Thrust with a specific impulse of 318-321 seconds. In addition, Yamal 402 is equipped with four SPT-100 plasma thrusters. The Stationary Plasma Thrusters provide 83 Millinewtons of thrust each. The spacecraft will operate from 55 degrees East in Geostationary Transfer Orbit and it has an operational lifetime of 15 years.A brief (good) read about the Propulsion Systems featured in this Satellite (9 pages in PDF):www.thalesgroup.com/Portfolio/Documents/Propulsion_Systems/
The data in my preceding post was directly received on my email from Khrunichev so I suppose that they are those of the SC. They are similar to those received for the preceding Proton Launch for ILS. More detailed parameters of the last events will come in several hours.Wait and see.
Whoops. Corrected
http://www.federalspace.ru/main.php?id=2&nid=19753Roskosmos informs that Yamal-402 satellite's systems are working well. There will be two burns of spacecraft's engine for its delivery to planned orbit. The first burn will be tonight. On January 8th spacecraft will be given to Gazprom Space Systems.
Seems to be a pattern these days....Briz-M gonna fail every time there would be a russian payload...
Quote from: owais.usmani on 12/09/2012 07:16 amSeems to be a pattern these days....Briz-M gonna fail every time there would be a russian payload... Interesting, but take a look at this: In the past 24 months a total of 22 Briz-M or Briz-KM missions have flown. Four of those are failures. That put's the failure rate for Briz on 18 percent over the past 24 months. That's a pretty bad number.

Operations with Yamal 402 Spacecraft Statement from KhrunichevOn 9 December, during the target orbit insertion phase, the Yamal 402 spacecraft separated ahead of the scheduled time. At present the spacecraft is under control. The delta insertion profile is being currently defined for translating the spacecraft to its station and subsequent commissioning. Early on 9 December evaluation was performed of the Yamal 402 orbit parameters. All SC systems are functioning nominally. Experts believe two additional burns of the propulsion system will be required for the delta insertion of Yamal 402 to the design orbital slot. The first such burn is scheduled for the late Sunday-early Monday. Following the completion of all maneuvers, the spacecraft will be handed over to OAO Gazprom Space Systems for operation as originally planned, i.e. on 8 January.
Bad luck to the ILS team who always try so hard, and also to the Proton team who get their booster running perfectly only for the transfer stage to glitch.This has got to be a good thing for Arianespace, Sea Launch, SpaceX and maybe even ULA. Every time Proton/Briz-M has an anomaly, the risk of using it starts looking like it outweighs any cost advantage. ILS might start looking seriously at getting another rocket provider.

SpaceX has no record in the GTO business. ULA, with its $400+ million launches, can't compete. Ariane 5 is the reliability winner here. - Ed Kyle
Btw, as mentioned a few posts back 12070B/39023 appears to be the APT tank. Note that its first TLE is time tagged 16:52 UTC, although separation reportedly occurred 10 minutes later at 17:02 UTC.

Note that its first TLE is time tagged 16:52 UTC, although separation reportedly occurred 10 minutes later at 17:02 UTC.This is not unusual - the TLE time tag is usually not the epoch of orbit determination, but the epoch of equator crossing on that orbit - depending on parameters it can end up before the time of the actual observations,as in this case.
A somewhat tangential topic: ex-ILS chief technical director James Bonner was charged with fraud charges in the US (Virginia) in October, associated with setting up shell companies and taking away Russian federal money (amount not known) for paying expertise on documentation analysis for ITAR compliance. This apparently lead to the sudden change of the whole ILS leadership earlier on. (or at least from what I can intercept from the Russian news report)Are we seeing the downfall of ILS and the annihilation of the Proton? Edit: This is the case filed in Alexandria, VA: http://dockets.justia.com/docket/virginia/vaedce/1:2012cv01140/287043/
Are we seeing the downfall of ILS and the annihilation of the Proton?
Here are a few calculated numbers based on public data:Shutting down the Briz-M 4 minutes early corresponds to an underperformance of 0.7 km/s. That is consistent with the TLEs for the object 12070A/39022.The planned deployment orbit (7500 x 36000 km x 9°) was 1 km/s short of GEO. Hence, the satellite will have to provide a total delta-v of 1.7 km/s to reach GEO. Given an isp of 320 s for the apogee engine that means an additional 650 kg of propellant (1850 kg instead of 1200 kg for a s/c separation mass of 4500 kg).If the electric thrusters with an isp of 1500 s are used instead then it would (differences of continuous thrusting vs. impulsive maneuvers set aside) consume an extra 200 kg only. There were, however, no data on actual tank capacities at hand to explore the options.Nonetheless, it would be interesting to see how the reported four year penalty in lifetime came about. If we spread the missing 700 m/s evenly across four years we get 175 m/s/yr for stationkeeping. For the nominal life of 15 years that makes a delta-v budget of 2625 m/s which looks way off. So, 15 years was probably with some margin and the new lifetime of 11 years is without.Btw, as mentioned a few posts back 12070B/39023 appears to be the APT tank. Note that its first TLE is time tagged 16:52 UTC, although separation reportedly occurred 10 minutes later at 17:02 UTC.
Wow, claim that it may not delay Satmex-8.http://ria.ru/science/20121209/914023802.html
Satellite acquisition was carried out and the solar panels partially deployed. The satellite was confirmed to be nominal

Although you state the otherwise, the Russian media says;"Ожидалось, что "Ямал" выйдет на геопереходную орбиту в воскресенье, 9 декабря, в 02.28 мск...-It was expected that the "Yamal" come to geosynchronous transfer orbit on Sunday, 9 December, at 02.28 MSK. "at http://ria.ru/space/20121210/914085760.htmlSo, the amount of fuel and DeltaV requirement on your post might need an update, if the news is correct.
So after all this, do we know the s/n of this newly failed Briz-M? 99535 maybe?
Quote from: akula2 on 12/10/2012 07:52 pmSatellite acquisition was carried out and the solar panels partially deployed. The satellite was confirmed to be nominal A question for clarification: The partial deployment of the solar panels was part of the plan? What is the reason behind it? (Or do I understand that incorrectly and what they're saying is, that the satellite is performing nominally except for a partial deployment of the solar panels?)
Partial solar array deployment right after injection in GTO is standard procedure.
Thanks, that's interesting. What's the reason behind it? To minimize loads during the following manoeuvers?
Luanching a massive investigation every time this happens just doesn't seem cost effective to me.Rockets have standing armies to launch them.Highly skilled aerospace workers.Stand them down and you still pay them, your cost per launch is going up.

The Strategic Rocket Forces don't specialize in any one type of rocket, they are generalists, so if Proton is grounded, the standing army launches Soyuz.
That doesn't mean the generalists have fixed the root cause.
Gazprom’s Yamal-402 Reaches Correct Orbit http://www.themoscowtimes.com/news/article/gazprom-satellite-reaches-orbit-after-correction/472957.html
12/12/2012 There remains one stepExperts of the Mission Control Center of the European company Thales Alenia Space have implemented the third of four planned maneuvers final ascent Gazprom satellite "Yamal-402" to the calculated point in orbit, the hosts announced the device, not too successfully launched from Baikonur on December 9."According to preliminary estimates, the maneuver is successful," - "Interfax" by "GSS", without specifying at what height could raise the spacecraft at this time.If success is confirmed, will make the second maneuver to "put the squeeze" communications satellite to the desired point in the geostationary orbit. A date to be determined later.
On Dec. 12, 2012, the semi-official Interfax news agency quoted Gazprom representatives as saying that controllers of Thales Alenia Space in Cannes, France, had succeeded in conducting the third out of four planned maneuvers to insert Yamal-402 into its planned orbit. According to the Russian media, the first engine firing onboard the satellite was conducted during the night from December 9 to December 10 and the second maneuver took place during the night from December 10 to December 11, 2012. According to RIA Novosti news agency, an hour-long third firing was conducted during the day on December 12 and the final orbit correction was planned for the night from December 14 to December 15, 2012.
That has become obsolete so I asked about it. Recently formed Russian Aerospace Defence Forces is in charge of all Satellite launches in Plesetsk. But Roscosmos manages Baikanour Satellite launches along with Aerospace Defence Forces. I guess the upcoming Vostochny project in Eastern Russia will be jointly operated too.
Apparently the Russians now blame the failure on a turbopump bearing destruction during the final burn.http://en.rian.ru/science/20121225/178385673.htmlHow frequent does that happen before in rocket engine flights?
Also, Kommersant's analyst, Ivan Sofronov noted, that this is not the first case of turbopump bearing destruction. In Feb 2006, Briz-M failed to deploy Arabsat-4A, later the failure was attributed to the bearing destruction, and "КБ Химмаш" concurred with this conclusion.
= the board believes that turbopump bearing destruction was the most probable cause;= Turbopump developer and manufacturer ("КБ Химмаш") will conduct testing of all its turbopumps (that's how the put it in article - ALL);
someone put forward the hypothesis
«Новости космонавтики» 01.2013 А. КрасильниковПосле этого Роскосмос принял решение детально перепроверить произведенные «Бризы-М»: №99528 и №99533, находившиеся на космодроме, а также №99534 и №99535, пребывавшие в Центре Хруничева. На это потребовалось время. В результате 14 октября на «Протоне-М» первым после аварии полетел спутник Intelsat 23. Причем для его запуска использовался «Бриз-М» №99534, доставленный на Байконур 21 сентября, а не №99528, хранившийся в МИКе площадки 92А. А вот «Луч-5Б» и «Ямал-300К», как изначально планировалось, отправились на орбиту на блоке №99533.Как сообщил НК заместитель директора Завода по эксплуатации ракетно-космической техники Центра Хруничева по летно-испытательной базе «Байконур» Леонид Горюшкин, «Бризы-М» №99528 и №99533 были подвергнуты специальной проверке прямо в МИКе площадки 92А.
