Observers are still being recruited to watch the two Fregat burns. Not all of them are on Earth. More to come.

Interesting... So ISS will be in good position(s) to view the burns?

I'm still quite confused of the name of the launch vehicle

Zenit-2SB41.1 two-stage rocket plus Fobos-Grunt satellite equals Zenit-2FG (or Zenit-2SLB, but not Zenit-3F) rocket.
Cheers for the clarification!
The idea is that '3' requires some third stage in addition to basic Zenit-2SB type vehicle. In the case of Fobos-Grunt, there is no third stage per documentation, even if Fobos-Grunt ADU propulsion unit is a clone of Fregat.

 So what is unique about this rocket that makes it a Zenit-2SB41?

That it has a different fairing (like Zenit-3F) and probably a special payload adaptor to fit the Fregat-like propulsion module.

     Does the international cooperation involved - okay, it's mostly China, but you know what I mean - mean real/hi-res launch pics, or just the usual postage-stamps?

There's a lot of European involvement on instruments, so I wouldn't say it is "mostly China." Plus, the Planetary Society has an instrument onboard, so it's possible they have somebody at the launch site.

I think the one from the phobos.cosmos.ru page is right,

Thanks knotnic!

Do you want me to say a few words about the Bulgarian instrument aboard the mission?

Yes! Personal observations are always welcome.

Then I will be more than happy to share something...

I was glad to present the Bulgarian instrument with a fellow scientist from IKSI-BAS on the National radio! Right now I'm also working in the academy, although in a different institute... The scientist I know personally was very excited to talk to me about our participation on Phobos-Grunt. She was working on some of the most ambitious projects like the SVET greenhouse aboard Mir and she's a brilliant scientist here... A little offtopic - she told me that she was running an experiment in parallel with the Mars 500 crew - again, about greenhouses and growing plants in space. Right now I know that she has published a peer-reviewed article, but I didn't have much free time to read it. I will read it as soon as possible..

About the Bulgarian instrument Phobos-Grunt that is named Lyulin-Phobos... It's a small instrument - the same size as a pen! Our instruments dedicated to radiation science are small and cheap and that's why they are preferred in the whole world. Similar instruments flew aboard Mir and aboard the ISS. A similar version also flew aboard Chandrayaan-1 to the Moon in 2008. So here, in Bulgaria, we have a very good science group who work in the field of radiation science. I hear also they will work with Russia on the Luna-Glob project.

The instrument will measure radiation from distance 1.0 to 1.5 AUs from the Sun - this covers the distance from Earth to Mars... and it will also measure radiation in Mars orbit and on Phobos

The instrument will improve the current models about risks during possible Manned Mars missions in the future

The instrument will work together with our instruments on the International Space Station so our scientists can compare results...

I hope you understood everything I posted, I'm not a native English speaker...

What kind of radiation, specifically? Galactic cosmic rays, etc?

Greetings,

This is a short description of the instrument: http://www.meetmatt-conf.net/aogs_archive/2005/ST/58-ST-A0234.pdf ... another article about one Lylin-type instrument is presented here: http://www.ias.ac.in/currsci/feb252009/544.pdf

In short words, these instruments measure radiation from both Solar and Galactic origin. Corpuscular and electromagnetic radiantion. Charged particles and gamma rays...

Is there any GRAU designation for Fobos-Grunt?

Do we have an English-language translation of the statement being read right now on the tsenki feed? I'm not up on my Russian.... :-\
