Jester, the link http://coopi.khrunichev.ru/video.htm has worked live for KazSat launch (June 17, 2006) and will be worked live again for KOMPSat-2 launch (July 28, 2006)... This link will not work live for today's launch, because this launch does not relate to Khrunichev enterprise...

Anik,

thanks for that, it was just strange as it worked this afternoon, but now it has stopped, so I had hopes that maybe they were doing something

PRESS-RELEASE
on prelaunch processing of BelKA earth remote
sensing satellite for the Republic of Belarus


Jule 26 2006. Baikonur cosmodrome
Final operations are being performed at Baikonur cosmodrome to prepare Belorussian spacecraft BelKA, the earth remote sensing satellite, for launch.
Spacecraft BelKA has been developed by S.P. Korolev Rocket and Space Corporation Energia using the Yamal space bus.
The BelKA is designed to receive earth surface area images within both visible and infrared spectral bands with a high spatial resolution, as well as transmit the generated images digitally to ground receiving stations.
Dnepr launch vehicle is to place this spacecraft into solar-synchronous orbit at the altitude of 511 km and with an inclination of 97,4 degrees.
Ground receiving stations located in Moscow, Minsk and Khanty-Mansiysk will be involved in reception, storage and processing of the downlinked information.
Mission Control Center located in the city of Korolev, Moscow Region, will be responsible for missions control.
 
Jacques :-)

According to http://lenta.ru/news/2006/07/26/liftoff/ (in Russian), Dnepr rocket is launched on time!... :)

Calpoly site reporting failure...

Which satellites were actually on board? Belka, Baumanets, Unisat-4, and some cubesats (3 PPODs?)
Tsenki site reported also PICPOT (Turin), while earlier messages talked about Almasat, Palamede,
JAESAT, Saudisat not listed on Tsenki.

That is the risk of using converted ICBM's for space launch.  The US was burned by the Atlas E a few times and so the Atlas H was developed  for better reliability.  Smallsats have to realize that some of the lower cost LV's have higher risks.  Working that issue as we speak.  Trying to find out if there would be more XXXX spacecraft to fly if there was cheaper LV's with higher risk.

The converted Russian ICBMs are cheaper, but you have to risk not all that much better than a 50/50 chance of mission success.

This report,  which says that the failure occurred during the second stage burn, doesn't quite make sense.  The first stage is supposed to burn for 130 seconds, followed by a 190 second-long second stage burn.

Cal Poly also said that the first stage completed its burn, so perhaps the failure occurred 86 seconds into the second stage burn.

First R-36M2 failure since 1988.

Makes you wonder if we ever had a war in which those ICBM's were used and launched, and they failed.....

Not quite that bad.  This was the first Dnepr failure in seven orbital attempts.  It was the first R-36M2 failure since 1988.

Six out of seven is the same result provided to date by the U.S. Taurus launcher, which is based on the MX ICBM first stage.

According to federalspace.ru first stage sep. for dnepr is at 109 sec.

There is not much to see, but here it his the launch video from http://cubesat.calpoly.edu/ at http://polysat.calpoly.edu/DNEPR-BelkA.wmv and the telecom conversation at http://polysat.calpoly.edu/telecon.mp3

Hmmm.

This site:  http://www.russianspaceweb.com/dnepr.html
shows something closer to the 130 seconds.  www.astronautix.com also shows 130 seconds.  

But I do get 102 seconds when I divide vacuum thrust (461.2 tonnes) by vacuum specific impulse (318 seconds) to get 1.45 tonnes per second burn rate, and then divide 147.9 tonnes (the reported first stage propellant mass) by the burn rate.

Hmmm.
