Proton-M rocket for the launch of Inmarsat 4-F3 satellite has arrived to Baikonur cosmodrome yesterday.
-
Do you have any information about waiting for this launch because of failure of Proton-M aboard with AMC-14?
Thanks
-
50 days after the failed launch of AMC-14, Roskosmos is ready to resume launching Proton-M/Briz-M.
ITAR-TASS reports that the deputy head of Roskosmos has declared this Monday to journalists that the reasons for the failure had been eliminated and that nothing prevented the launch of Proton-M/Briz-M.
Also Monday, the Russian government has published Decision N° 618-r authorizing the Ministry of Defense to lend equipment and personnel for the launches of Astra-1M, Nimiq-4 and Inmarsat-4F3 with Proton-M/Briz-M.
-
I bet these next three launches will use the 5-burn/9 hour Briz-M mission profile (longest burn lasting less than 18 minutes) :)

Anik, I take note that you prefer to incorporate my two messages in the already existing "Inmarsat 4F3 launch" rather than maintaining the specific thread I tried to create for Proton-M/Briz-M flight resumption.
Be aware that Astra-1M and Nimiq-4 could well be launched before Inmarsat-4F3, that's why IMHO a specific thread for Proton-M/Briz-M launch resumption might be more appropriate ....

Be aware that Astra-1M and Nimiq-4 could well be launched before Inmarsat-4F3, that's why IMHO a specific thread for Proton-M/Briz-M launch resumption might be more appropriate
Astra 1M launch is currently scheduled in the fourth quarter (source: SES schedule (http://www.ses.com/ses/siteSections/group/services/satellitefleet/NextLaunches/index.php)).
I know nothing about launch dates for Nimiq 4 and CMBStar satellites, but they were always planned after Inmarsat 4-F3 launch.
The rocket for Inmarsat 4-F3 is already on Baikonur cosmodrome. According to Khrunichev schedule (http://www.khrunichev.ru/khrunichev/live/) and today's Kazakhstan Today report (http://kz-today.kz/index.php?lang=rus&uin=1138536794&chapter=1153447204), the next launch of Proton-M rocket with Briz-M upper stage will be with Inmarsat 4-F3 satellite.
So it was sober decision to include your posts into this thread. I do not want to watch equal discussions in two separate threads. :)

FROB concludes first phase of review
http://www.ilslaunch.com/proton-return-to-flight-communication
"May 13, 2008 -- The members of the ILS Failure Review Oversight Board (FROB) have concluded two weeks of meetings in Moscow, and concurred with the Russian investigative commission on the cause of the recent Proton Breeze M failure. Both boards determined that the failure was caused by a ruptured exhaust gas duct, which led to a shutdown of the turbo pump feeding the Breeze M engine.
The next phase is for the FROB to evaluate the corrective actions to be taken before the vehicle is cleared for return to flight for ILS missions. Khrunichev will be performing additional analysis and engine tests that are scheduled for completion in mid-June, after which the FROB will reconvene in Moscow"

ILS Close to Return to Flight as Khrunichev Takes Control

"PARIS - The builder of the Proton-M launch vehicle has begun tests of a newly designed gas duct to replace the model that failed March 15 and will announce a return to flight date and an updated manifest by the end of June, according to the president of the company that sells Proton launch services worldwide"

PROTON BREEZE M CLEARED FOR RETURN TO FLIGHT
http://www.ilslaunch.com/news-061608
"MOSCOW, June 16, 2008 – The Failure Review Oversight Board (FROB) convened by International Launch Services (ILS) has cleared the Proton Breeze M to return to flight this summer, following its examination of test results and analysis regarding a redesigned engine component.
The Russian-built launch vehicle suffered a failure during the March 15 launch of the AMC-14 satellite from the Baikonur Cosmodrome. During that mission, the Breeze M upper stage shut down two minutes before the end of the planned second burn of its engine. As a precaution, the AMC-14 satellite was released into a lower-than-planned orbit.
A Russian State Commission investigated the failure, analyzed possible scenarios and reviewed the processes, hardware and systems related to the engine and its supporting systems. Both the Proton booster and the Breeze M upper stage are built by Khrunichev Space Center, which is the primary shareholder of ILS.
On April 21 the commission announced its conclusions: that the failure was caused by a ruptured exhaust gas conduit, which led to a shutdown of the turbo pump feeding the Breeze M engine. The commission recommended a number of corrective actions, with the primary step being Khrunichev’s replacing the existing conduit with a thicker-walled conduit.
ILS assembled an independent FROB to review the Russian commission's findings in early May.
Khrunichev subsequently performed additional modeling as well as component and certification engine testing to determine root cause and validate the recommended corrective actions. The FROB reconvened in Moscow last week to review the analysis and test results. The FROB agreed that the root cause of the failure was that the conduit walls were thinner than the minimum specification, which when combined with other factors led to the rupture.
Khrunichev has successfully completed certification testing of a flight engine with the new conduit. The new conduit is being incorporated in all future engines.
The FROB was led by ILS Chief Technical Officer Jim Bonner. Membership included propulsion experts, members of the insurance community, and representatives of the customer for upcoming launches.
Bonner said: “The Khrunichev team, including Khimmash, manufacturer of the Breeze M main engine, demonstrated its commitment to mission success at every level. We are confident that the root cause has been determined and that the corrective actions provide more than enough margin to prevent this from happening again.”
Bonner continued, “In addition to making this change in the engine, Khrunichev has moved forward with its overall quality initiative by completing a detailed quality assurance review, including an independent audit, in support of near-term Proton Breeze M missions.”
“I appreciate all the energy shown throughout this intensive and thorough process,” ILS President Frank McKenna said. “We thank our customer participants and the insurance community for their contributions to the FROB. ILS is committed to continued improvement and visibility, as part of the steps we and Khrunichev are taking to enhance the overall reliability of Proton.”
McKenna added: “We anticipate that Inmarsat, which is the next scheduled commercial customer, will announce its selection of a launch date soon. So now the ILS-Khrunichev team must turn our focus toward making that and all other Proton launches successful.”
ILS is scheduled to begin briefings in July for the underwriting and customer communities"

INMARSAT AND ILS SET AUGUST 14 FOR PROTON FLIGHT WITH INMARSAT SATELLITE
http://www.ilslaunch.com/news-070108
International Launch Services (ILS) has scheduled its next Proton Breeze M commercial mission for August 14 (August 13 GMT) from the Baikonur Cosmodrome in Kazakhstan, with the launch of the Inmarsat-4 F3 satellite.
The satellite is scheduled to be shipped to Baikonur in early July for a six-week launch programme. The satellite, an EADS Astrium Eurostar 3000 model, will weigh approximately 6 metric tons at liftoff, perfectly suited for the Proton Breeze M’s lift capability. Khrunichev Space Center of Moscow, the majority shareholder in ILS, manufactures the Proton system.
The Inmarsat-4 F3 satellite will complete Inmarsat’s next-generation global satellite network, providing broadband MSS services to users everywhere.
This is the first ILS mission since a Breeze M upper stage suffered a failure during the AMC-14 mission in March. The Proton Breeze M is ready to return to flight now that a Russian State Commission and an ILS-led independent review panel have concluded their inquiries into that incident and corrective actions have been completed.
“Having participated in the failure review process in its entirety, I am satisfied that the appropriate actions have been taken to deal with recent failures and to reassess the quality of the Proton vehicle. Inmarsat now expects to transport the satellite to the launch site and complete certain other formalities in sufficient time to target the launch date announced today,” said Gene Jilg, Chief Technology Officer for Inmarsat.
“We thank Inmarsat for its support and patience,” said ILS President Frank McKenna. “We know how important this satellite is for the continued success of Inmarsat’s growing broadband services, and we look forward to the start of the campaign in the coming days.”

I believe those are particles of concrete flying out of the flame trench. In past years, there wasn't as much seen. I am not sure if that is particular to Pad 39 or just the current refurb process on the flame trench.

EDIT: Me stupid. 39 here, 39 there, flying debris everywhere...
-
There are sparks flying in every Proton launch, no idea whether they're some kind of nominal "engine plug" or pad material. However, I remember seeing at least another launch with lots of sparks, perhaps a bit less than this one but quite a lot nevertheless.
I'm guessing dirt and stones can get pretty hot if they're caught by the exhaust and Baikonur pads don't seem to be as impolute as Canaveral's. There must be quite a lot of stuff sitting on the pad to form that cloud Protons make in every launch, given the hypergols shouldn't form it.

The Breeze M upper stage of our Proton M rocket continues its climb into space with the Inmarsat-4 F3 satellite. We have received confirmation that the 1st and 2nd burns of the upper stage occurred and shut down as scheduled.

I realize this is proprietary info but I'm curious what's the $$$ range for the cost to the customer of a commsat like this? Just the sat hardware itself without ground ops/insurance/launch. Any pointers?

3rd and 4th burns are now complete, per the blog.
-
I believe that the 3rd burn should have been completed by now (10:43 pm EDT).
We have confirmed that the Breeze M upper stage has successfully completed its 3rd & 4th burns, as well as jettisoning its additional propellant tank. The vehicle is now in a 5-hour coast period, during which we will have nothing to report. The 5th burn is scheduled for around 3:35 a.m. Eastern time, or 7:25 GMT. Separation of the Inmarsat 4 spacecraft is scheduled to follow that by about 16 minutes.

ILS PROTON SUCCESSFULLY LAUNCHES INMARSAT-4 F3 SATELLITE
BAIKONUR COSMODROME, Kazakhstan, Aug. 19, 2008 – A Proton Breeze M launch vehicle successfully lifted the Inmarsat-4 F3 satellite into orbit today, marking the third mission of the year for International Launch Services (ILS).
The Proton Breeze M vehicle, built by Khrunichev Space Center of Moscow, lifted off from Pad 39 at the cosmodrome at 4:43 today local time (18:43 EDT Monday, 22:43 GMT Monday). After a 9-hour-3-minute mission, the launcher released the satellite into a geosynchronous transfer orbit.
The Inmarsat-4 F3 satellite, a Eurostar 3000GM model built by EADS Astrium, is expected to go into service at 98 degrees West longitude, where it will deliver mobile broadband services over the United States for Inmarsat of London.
“This is a major milestone event for Inmarsat. ILS is proud to be a part of the construction of their global service with the successful Proton launch of Inmarsat-4 F3 today,” said ILS President Frank McKenna.
“Congratulations to ILS on another successful Proton launch. The F3 launch has been highly anticipated. This satellite will enable Inmarsat to complete its BGAN services to subscribers across the globe,” said Andrew Sukawaty, president and CEO of Inmarsat. “We thank ILS for its due diligence in returning to flight successfully."
