WOW, thanks for the link!

Launch was at 2359 UTC Jun 26, and separation was at 0637 UTC Jun 27 (NOT 0737 UTC as spaceflightnow and Satori have said. Note that MSK = UTC+4 not UTC+3). SpaceTrack data are consistent with a 2359 UTC launch.
Apogee burn was over 90 deg E.

My understanding is that current Moscow time is MSD (Moscow Daylight Time), which is UTC+4. Moscow Standard Time (winter time) is MSK, which is UTC+3. This appears to have been the source of the time confusion, since initial Russian media reports gave the time as 03:59 MSK, not MSD as they should have.

The Novosti article reports that the upper stage was a "DM-3". This could be a leftover item of the commercial DM3 variant of the 11S861-01 DM-2M, or maybe a designation for the 11S861-03
which had been planned for the Proton-M. Would any of our Russian friends care to comment?

On my mind, it's same "DM-3" as Kazsat had in 2006.

Proton-K/DM-2M/mod.DM3(based on 11S861-01) = Proton-K/DM-3

11S861-03 = DM-03 still not flying yet, and nobody knows when will be first flight-test, because of postponed "Yamal-300"

A great Proton Video from the Launch (wmv-file)- Sound very good!

That's an awesome launch video, thanks very much for the link! I think I never saw a Kosmos launch with such detail (well, perhaps a Soyuz Meridian launch a few years ago, it's here in the forum somewhere), you could see the Proton actually punching through the cloud cover!

I was told, that for this launch was used old 11S861 (without -01) from military storage. So "DM-3" still same PR fiction as for Kazsat launch was.

If this is an "Oko" payload, is this the same spacecraft type as launched by Molniya-M?

pm1823 · « **Reply #29 on:** 07/04/2008 10:58 pm »

Nope. For "Molniya type orbit" was used 73D6 or US-K, this one was for GSO - 71Kh6 or US-KMO.

To make it more complex, some early geostationary EW sats were of the 73D6 (US-K, "Oko") type.

The 71Kh6 or US-KMO type is called "Prognoz", not "Oko"

Wrong. You make mess with system names and sat names. Old geostationary segment of "Oko" system was called "Oko-S" (Око-С), sats in it were named as US-KS (УС-КС) or 74Kh6 (74Х6), and based on the same old prototype with 73D6(73Д6) -> 5V95 (5В95).

|->OТM 73D6
"Oko" 5V95 ->|
|->GSO 74Kh6

| ->OTM 73D6
"Oko-1" -> |
|->GSO 71Kh6

And we can be sure, that it's only name of a fly-craft, so sats with same name can have difference with payload.

"Prognoz 1-7" is just a fake name for international registration of the stationary points 24°W, 159°W, 12°E, 35°E, 80°E, 130°E, 166°E.

Ah, this makes sense. Thanks for the clarification.

I think it is DM-2 as serial number appears to be 111L
and SOZ were discarded
Proton was 410-14
