Did anyone notice the sparks which appeared to be coming from the lightning tower nearest the camera. I was wondering whether this could indicate some form of damage to the launch facilities.

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.

We're halfway across the world for this one.
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.

from the blog:
Posted by ILS Communications Team, 8:42 p.m. EDT on 18 August 2008
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?

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.

Does anyone know where the 3rd stage impacts during such missions?

Somebody must be in a different world. Who really cares about sparks and damage tot eh launchpad. ILS is in the business of launching satellites and the launchpad can be repaired - DUH!!!

Obviously you didn't see 39A after STS-124...
I know, totally different story, but the pads are important as well.

ILS PROTON SUCCESSFULLY LAUNCHES INMARSAT-4 F3 SATELLITEBAIKONUR 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."

Does anyone has the serial numbers of the 8K82KM Proton-M and Briz-M used on this launch?
Thanks!

this
http://spaceflightnow.com/proton/i4f3/ says $1.5 billion investment (not sure if just for F3 or the entire trio)
[edit] anyways, congrats on the successful return to flight! (it appears everything went smoothly after the Breeze change)
