MiR is another name for Yubeleny-2?
I guess MiR stands for Mikro-(R-something)?But we don't know what?
Do we know which Gonets satellites are the ones still operating?
Following the decision by the Russian State Commission to return Rockot to flight after the failed injection of the GEO-IK2 satellite on February 01, 2011, the preparation of the Rockot launcher as well as the two Russian spacecraft "Gonez-M" and "MiR" for their launch has started at Plesetsk Cosmodrome. The return-to-flight of Rockot is now planned for July 2012. This will be the first Rockot launch in 2012.
Do we know what type of problem on Briz-KM US they are dealing with
The launch is planned at 01:35:00 UTC on July 28th, as per Roskosmos.
Is there any particular reason why this launcher is so little used, is it down to its two past failures or does it just serve an area of the market where there is little demand for flights or where there is heavy competition from other launchers?

Someone (Jonathan ?) knows the number of Briz-KM burns ?
QuoteIs there any particular reason why this launcher is so little used, is it down to its two past failures or does it just serve an area of the market where there is little demand for flights or where there is heavy competition from other launchers? First, because it flies from Plestek, mostly to SSO and Molinya orbit. There is just less demand for this type of orbit then for GTO or LEO.They started out with this rocket in '95. But only when they had moved to Plestek in 2000 the whole process was ready for commercial payloads. But getting the whole erector and vertical integration process perfected took a long time. The Briz KM upper-stage made it more expensive then it's direct competitors such as the Cosmos 3M and Dnepr. The 2005 failure with Cryosat didn't help either, being the first major ESA probe to use this LV. And when the Rockot finally emerged from this failure there was a shortage of S5.92 engines that are shared between the Breeze M and Fregat upper stages. They could only produce 10 or so of these engines a year, and with the other launch vehicles bringing in more cash, Rokot was pretty much grounded again.Now it's finally getting it's stride back. Russia has finally retired the Cosmos 3M and it's associated payloads, Angara is still far away and Ukrainian Dnepr keeps getting tangled up in dropzone conflicts. So Rokot has become the small launcher of choice for Russia. However with Vega finally flying all the juice ESA contracts will probably be given to Arianespace. Such is politics
According to http://www.rosles-re.ru/files/file/120730_pusk_Rokot_Gontsi_17F13.pdf, Kosmos-2481 is 17F13 (or Strela-3) satellite.
First off, a photogallery of the launch site:http://www.novosti-kosmonavtiki.ru/content/photogallery/gallery_241/index.shtmlSecondly, the upper stage is referred to as: "Бриз-МД" (Briz-MD), so I would imagine that there was something different about this one.
