Nope, the Russian schedule thread now shows that the launch is planned on November 29th.

Does anyone know, what the difference between the Rodnik-S and the earlier Rodnik is?

If I understood correctly, previous three satellites (2005, 2009, 2010) were Rodnik-S (14F132) too.

Rockot Places Three Russian Satellites into Orbit
On January 15, 2013 a Rockot launch vehicle using a Breeze-KM upper stage successfully launched three military communication satellites into orbit. The launch took place at Plesetsk Cosmodrome in Northern Russia. All satellites were injected precisely into their target orbit. This first launch of a Rockot in 2013 will be followed by further Russian federal launches as well as the combined launch of three Swarm satellites by Eurockot Launch Services this year.

its normal around the ignition and early launch portion of the flight. It is un-ignited propellant and is a common site for hypergolic boosters.

Thanks. I don't remember seeing anything quite so orange on other launchers, is it something that comes from the fact that it is converted ICBM?

it partly has to do with fact that Rockot still uses its silo launch tube above ground and that there is not a flame trench for deflection so it just kind of hangs around. You will see it with Proton to if you watch the flame trench cameras when ignition occurs.
Also Rockot is from UR Booster family in the UR-100 subfamily and uses the same fuel and oxidizer.

In all four previous Rokot (Strela-3) launches, the Briz-KM ended up in an orbit with a lower perigee. Did the Briz fail to perform a depletion burn this time I wonder?

If the mission was successful with the three satellites placed on the correct orbits, why is this not a very good start for 2013?

Because the failure to reignite for deorbit shows, that there is still something wrong with the Briz stage. This will certainly lead to more delays for the return to flight of the Proton-Briz-combination.
-
There's also the possibility of another Briz explosion. Unvented Briz-stages have a tendency to explode and this time the high perigee would mean long-lasting debris.
-
The withdrawl is by high-pressue tanks and the four 11D458?
-

Let me translate this into a question about the final burn being performed not by the main engine, but by the 4 small thrusters that are fed by the high pressure tanks. IIRC, the 4 small thrusters are the same as is used on FGB and MLM, and have a good reliability record; if the perigee drop burn failed due these thrusters not firing, it will be difficult to pinpoint the problem.

Yes, you remember correctly ! ;)
-
Is it really known that a perigee lowering burn would have took place? There is a chance that this launch almost reached the maximum capability of the rocket.......
Oh and this really cool video caught the huge fume of reddish hydrazine+N2O4 firing off as the rocket lifted off! http://tvzvezda.ru/news/nocomment/content/pusk_rakety-nositelya_43rokot59_kamera_1601.html (http://tvzvezda.ru/news/nocomment/content/pusk_rakety-nositelya_43rokot59_kamera_1601.html)

All 4 previous multiple-Strela launches to this orbit did make a burn to lower perigee to 1200 km. The last one with the extra Yubilyeniy payload should have had at least the payload requirements of this one, so I don't think it's plausible to think that the mission didn't plan one.
However, if for some reason the engine was less efficient than usual it's possible depletion was achieved - which would still be bad news for Briz flights but better from the debris-time-bomb perspective, so it's important to know *why* there was no extra burn.
-
What we don't know is whether the depletion burns are generated by the main engine to empty the main prop tanks, or the small thrusters to deplete the high pressure tanks.
-
Knowing if Briz-KM failed for a final deorbiting burn will not be easy. And more difficult due to the military nature of the mission. But if a final failure accured "leaks" from unofficial sources in russian space industry will tell us in the next days.

Likely a file image, as the viedos of the current launch (see on http://www.kosmonavtika.com/lancements/2013/15012013/15012013photos.html) show a Rokot with a white fairing, not the dark one (unless the video footage was also a file video)
-
Since the launch was at 16h25 GMT, it was a night launch.

Sounds like the Russians have confirmed that something went wrong with the retro-burn of the Briz-KM, as they have delayed the next Rokot launch to June because of "launch vehicle problems": hhttp://novosti-kosmonavtiki.ru/news/5023/ (http://hhttp://novosti-kosmonavtiki.ru/news/5023/)

According to Izvestia, the satellites did not reach the intended orbit and only two of the three Rodnik-satellites could be activated while the third is considered a loss.

I had a look at their orbits on Heavens Above; in terms of apogee, perigee and inclination they look fine compared to other Rodnik satellites launched. Jonathan's SATCAT shows the Briz-KM in a comparable orbit, so if a failure occurred I doubt it affected the satellites' orbits.
If one of the satellites "couldn't be activated", that would suggest a spacecraft problem rather than a launch problem. If the Briz failed I strongly suspect it was between s/c sep and a disposal burn.
-
At closer look, the problem is more on Izvestia's journalism

Kosmos-2483 have not yet performed maneuvers unlike Kosmos-2482 and Kosmos-2484.

Is it possibly failed or do you think it might not be going to the similar location as the others.
-

It possibly failed because the Russian MoD possibly can not control it after dirty separation from Briz-KM and followed tumbling.

Did the Briz-KM also tumble; why it did not perform final manoeuvre?

Briz-KM shortly after sep went into a safe mode and did not execute de orbit burn or the CCAM maneuver. That is only information I have come across so far, but it is main source of Rockot delays besides SC issues for upcoming missions this year.

Still no orbit change for Kosmos-2483, clearly dead.

I have heard partial failure since two of the three separated nominally and burned to their final orbits. Briz-KM on this mission failed to perform CCAM maneuver and de orbit. TEL for Briz-KM was lost early if I remember correctly. I think it is mentioned by anik above.

A partial mission failure due to the one dead satellite, yes, but was that caused by a problem with the launch vehicle itself? The Briz KM stage seems to have inserted the satellite into the proper orbit, which would usually be considered a launch vehicle success regardless of the subsequent deorbit burn issue, but then both the satellite and the stage stopped working. Did they collide? Was there a problem during spacecraft separation? Etc.

Says that the three sats were not in the intended orbit but only close to it..
<
However according to a senior official of detachment B of the VKO staff, the satellites functioning is not affected "One satellite, which incorrectly was said to be lost, after insertion and had to be put on station (?), the two others - separated in different directions.
.Now they are all operating nominally in the interests of the GRU". The booster contractor Khrunichev ... corrected deficiencies in the control system.

Very interesting - so maybe bad attitude control in the last seconds of the burn and the deployment sequence messed up. Also interesting for the explicit statement that the payloads are for the GRU главного разведуправления
- Jonathan

So .... how did this one end up, three live satellites in slightly off-nominal orbits, or two live sats and one dead sat?
