Im still not sure whether its the RD-869 or RD-861K. I did find a news report that the latter was test-fired at the beginning of this year, albeit for the Tsyklon 4 programme.

Not only RD-869 throttled thrust matches that of AVUM (from VEGA brochure), also the Isp is almost identical. RD-861K thrust is way to big and Isp differs more.

A prototype of the P80 rocket motor, which will power the first stage of ESA's new small launcher - Vega, was successfully tested on 4 December at the Guiana Space Centre, Europe's Spaceport in Kourou, French Guiana. Ignition occurred at 12:35 local time (15:35 UTC/GMT).

How are they avoiding the oscillations occurring with solids? I've heard that Vega is advanced in this regard, which is one of the reasons it's been so slow to develop.

Since the Zefiro 9 underperformed on the second test firing, is it going to be modified and tested a third time or fly as-is?

Since the Zefiro 9 underperformed on the second test firing, is it going to be modified and tested a third time or fly as-is?

“The project team will rendezvous at Salto Di Quirra in June for the Zefiro 9 firing test,” announced Paolo Bellomi, Technical Director of ELV, the Vega launcher prime contractor.

I think he means that the upper stage engine has left the factory, and is on its way to wherever integration of the upper stage is taking place.

2GW_Simulations: correct
2Delicious: is there any other interpretation for my post?

Vega Readies for Flight - Status and Qualification Flight Preparation
http://www.esa.int/esapub/bulletin/bulletin135/bul135f_bianchi.pdf

The development of Vega passed major milestones in 2007 and 2008, providing essential results in terms of test data and design consolidation. These will lead to the Qualification Flight from Europeís Spaceport in French Guiana at the end of 2009. This will be an important step in the implementation of the European strategy in the launcher sector and the guarantee of access to space for Europe, as endorsed by the ESA Ministerial Council in 2003.

In 2012, Vega will carry ESA’s Intermediate eXperimental Vehicle into space. The vehicle will then return to Earth to test a range of enabling systems and technologies for atmospheric re-entry. A new video with computer generated animations of the vehicle and its mission is now available.

Successful first test for Vega’s Zefiro 9-A solid-fuel rocket motor

Yesterday, the Zefiro 9-A motor successfully completed its first firing test at the Salto di Quirra Inter-force Test Range in Sardinia (Italy). This was the penultimate firing test for the engine prior to the Vega launcher’s qualification flight, scheduled to take place by the end of 2009.

Widespread interest for the 2nd European CubeSat Workshop
http://www.esa.int/esaCP/SEM8S7WPXPF_index_0.html
23 January 2009
The Second European CubeSat Workshop, organised by the ESA Education Office, was held at the European Space Technology and Research Centre (ESTEC) in the Netherlands from 20 to 22 January 2009.

Following the success of a similar workshop in 2008, there was an even higher level of interest shown by universities and students for this year’s event, with more than 200 participants representing universities from many countries.

The first day of the workshop programme included a series of talks about the status of the nine CubeSats that will be launched as a secondary payload on the maiden flight of Europe's Vega launch vehicle – a flight opportunity offered to universities by the ESA Education Office, in cooperation with the Agency's Launchers Directorate.
