Do we have the serial numbers for the rocket and the culprit itself?

Horrible news  :(

I hope these upper stages get more reliable very soon.

Roscosmos talking about a failure on the Briz-M?

Phobos-Grunt (zenit but with Briz-M) and now this, Briz-M isnt having too much luck lately.

Fobos-Grunt used a modified Fregat, not Briz.  To the best of my (admittedly incomplete) knowledge Briz has never been used on Zenit, nor are there any plans to do so.



think the Britz is going to be an 'upgrade" to the Zenit

No Briz-M on Fobos-Grunt. Absolutely no relation between the two failures.

Okay, so this is the fifth Briz-M failure in 62 Briz-M launches? Eight percent failure rate.

Not quite - my info is several month old and i can not rule out, that the vehicle/payload allocations have since been changed.

So from http://www.ria.ru/science/20120807/718040335.html the first and second Briz-M burns were nominal (as confirmed from TM data) while the third burn did not occur and the stack is orbiting in the intermediate orbit 268 x 5000km x 49.9°

USSTRATCOM has catalogued Object A (the stack) in
266.9 x 5012.2km x 49.91°
(Object 2012-044A/ 38744 at epoch 0208UTC August 7)

Is there the provision to try to command the burn again (perhaps on a ground override command)?

The first elset at epoch 2309UTC on August 6 gives roughly the same result for 2012-044A (the stack):
266.5 x 5013.9km x 49.92°

2309UTC: would have been 9 minutes into Briz-M 3rd burn for a nominal sequence.... :(

the motor of satellite can be up to 36000km ?
or it still low orbit ?

Satellite observer Kevin Fetter saw four objects related to this launch flying in series at around 04:08 UTC, so it looks like the Breeze-M separated its APT and the two satellites after the engine failed.

Roscosmos and Khrunichev press release mentions a Briz-M 7s 3rd burn (instead of nominal 1085s)
So the issue is a premature shutdown of the Briz engine not a failed re-ignition.

Since there is no obvious sign of an orbit change due to separation for Object-A's 8 tles released so far, it's possible that Object A corresponds to the APT (which in the past has often been catalogued first).
