"Start-1 rocket will launch Israel EROS-B satellite from Svobodny cosmodrome at 16:47:16 UTC"
Do we have any information on this for the purpose of coverage?

From the top of my head, its a spy/imaging sat. Originally planned to be a constellation of 4 EROS-B's but reduced to one
The EROS A1 has been in orbit since 5 December 2000
EROS-B is the heavier brother of the EROS-A, has a better camera (0.8m resolution at 600km against the A version of 1.8m both have a swath of around 13 km)

I'll look. I'll take anything, even some translated Russian (I really need to learn Russian, but it looks like a very hard lanuage!

Here is a picture, and it's not so much a spy sat. (altought it sure can be used as such) but a commercial, high-resolution satellite
Info:
Fuel Lifetime: at least 10 years at 600 km
Camera: Panchromatic & Multispectral
Sensor type: CCD-TDI up to 32 levels
On-board recorder: Two fully-redundant recorders at 120 Gbit each
Data transmission rate: 450 Mbit/sec
Weight: 360 kg
Length: 2.17 m
Power: 800 w

BTW, one reason for this might be that they had originally planned more launches of EROS-A/B to build a bigger constellation (of 4) and they are behind on schedule, so they take the EROS-C spec. , and launch it as EROS-B and come with an even more advanced EROS-C in the future

Any info on the rocket?? I've never seen a Start-1 launch...nor heard of it!

The Start-1 four-stage solid-fuel launcher performed its first demonstration launch from Plesetsk in March 1993 with a 225 kg payload on board
As you might see it's derived from the SS-25 / RS-12M intercontinental ballistic missile.

Well then the makers should correct their site, because that is what THEY say it looks like.
http://www.iai.co.il/Default.aspx?docID=24919&FolderID=23860&lang=EN
Even the image name says B, so i'm guessing the opperator site got it wrong.
http://www.iai.co.il/pict/Space/ErosBM.jpg
Indeed, IAI should correct their site (This particular is from 2003). I have to dig up my sources, but what is now EROS-C was once, when it still was a constellation of four, EROS-B. When they changed their plans to a single EROS-B, they switched to a modified EROS-A design for the B-Generation and pushing the more advanced from B to C.

By Babel Fish, the pertinant details of the story are that EROS-B
was successfully inserted into the planned orbit, which was
roughly a 600 km sun synchronous orbit. Launch from Svobodny
was at 16:47 UTC. Spacecraft deployment was at 17:03 UTC.
EROS-B supplements EROS-A, which was also launched by a Start-1
on 12/5/2000.
Four-stage Start-1 has a 47 tonne liftoff mass. Start-1 was developed
"by the cooperation of industrial enterprises, headed by scientific and
technical center complex - MIT, created with the Moscow institute of
heat engineering". Start-1 launches can also take place from Plesetsk.
By my count, this was the sixth Start-1 orbital mission since the first
in 1993 (but the first such launch since 2001). All six Start-1 flights
were successful, but a single "Start" launch attempt with a five-stage
variant failed in 1995. Including the Start launches, my list shows
nearly 70 Topol'-based launches since 1982.

Thanks for that interesting video! It's kind of funny how the top cone falls to the ground before erection... looks like a cartoon!:) However, it's very nice to see such a "mobile" launch pad!
What are the little explosions that happen just before ignition, while the rocket is climbing through the cylinder? Any kind of system to make it go up?
Are there any images/video from yesterday's launch?? I've been looking for them, but I couldn't find any!

Here is a launch video of the Start-1 / EROS-A satellite from December 2000:
http://www.imagesatintl.com/files/Multimedia_Downloads/EROS_A_Launch.avi
Probably no other rocket has such a short time beween erecting of the launch vehicle to launch.
Gunter
An impressive launch system - frighteningly so when you consider that these missile are still active. It puts to serious shame all of the failed U.S. attempts to produce a mobile ICBM system (e.g. rail-mobile MX, small-ICBM, etc.).

A "solid propellant hot gas generator" produces the gasses that push the rocket up and out of the launch canister.
My guess is that the little explosions are charges firing to free the "sabots" that protect the launcher within the launch canister and the "seal sabot" that pushes the launcher out of the canister.
Just a guess though.

They weren't failed attempts to produce; the US systems worked. The US Gov't decided not to field the system

That was part of the failure - the decision (by Bush #1) not to field the alredy-developed, successfully-tested, cost-effective "Midgetman" (SICBM) while Russia went ahead at the same time with full-scale development of Topol'-M. The other part of the failure was the wasted effort, money, and time spent trying to turn the much heavier MX missile into a mobile launch system until the belated, practical decision was finally made to develop SICBM.
Now the U.S. can only sit and watch while satellite owners effectively fund Topol'-M practice launches (the EROS-B launch was performed by Russian "Space Forces" units) whenever a Start-1 launch occurs.

Im thinking of preparing a wikipage on the start Launch Vehicles and while pondering the whole thing a number of questions popped in my mind. Hopefully some of you can help me out here.
There is also a 5 stage version of the Start-1 LV, called Start. It is a larger vehicle because they added another 2nd stage to it. It was launched once from Plestek but it ended in failure. My question is, where was it launched from? It's 6 meter longer so I doubt that they could have placed it in a TEL like the Start-1. Is it possible to launch this longer vehicle from Svobodny Cosmodrome?
The second thing that made me wonder, how come the Start-1 actually fits in the standard TEL, its a good meter long then the ICBM and I was surprised by the extra space in the launch tube. Or have they made a special TEL for the commercial launches?

According to Novosti kosmonavtiki magazine, the launch of Start rocket was performed from site 158 of Plesetsk cosmodrome... There is special construction (hangar with sliding roof), called Krona, on site 158... Inside the hangar is the assembly-starting rack, on which assembly of rocket, installation of satellite, complex tests may be made... For performing of launch the roof of hangar is moving apart and the transport-starting container containing a rocket, is risen into vertical position by hydraulic system...
