Is this an actively stabilized RV with those tabs? Or are they fixed?

Looks like a high volume, high CG design.

I don't know why but I've got the impression that ESA is currently helping Italy to finance the development of all the technologies needed to build an ICBM (except the nuke itself) :

- the launcher through VEGA
- the reentry vehicles through EXPERT

Well I suppose I'm just being paranoid...

It's purely a testbed to gain more flight data in the high atmosphere to validate CFD codes and extrapolation to flight methods. The technology boomed in the last decade(s), but very little flight data was recorded in this period in Europe. The vehicle is really packet with plenty of advanced measurement devices.

Nevertheless, there is no active control during its flight, after separation from the 3rd stage of Volna. Also no TM link during flight. They hope to spot it under the parachute and find it after landing on Kamchatka and recover all recorded data  on-board.

The aim of the EXPERT project is to validate aero-thermodynamic models, numeric codes and ground test facilities by data, which was collected in a representative flight environment.

In order to make a good design of future spacecraft more precise data is needed particularly for the following aero-thermodynamic problems:

    * Effectiveness and heating of control surfaces
    * Interaction between shock and boundary layer
    * Transition of boundary layer from laminar to turbulent flow
    * High temperature and gas chemistry effects
    * Interaction between gas and surface such as catalysis and oxidation

The EXPERT capsule is designed in a simple geometry and consists of an ellipsoid in the nose region, which attaches to a conic body over a clothoide. Four even surfaces are cut into the conic body with four fixed flaps.

EXPERT Update

Expert Launch Contract Signed With SRC Makeyev

10 December 2009

The launch operations and vehicle recovery contract for ESA’s European Experimental Re-entry Testbed (Expert) was signed on 2 December in Moscow, Russia, between ESA and the Russian Makeyev State Rocket Centre.

Expert is currently scheduled to be launched on its suborbital trajectory in October 2010.

From ESA Bulletin Number 143 (August 2010)

Expert

Phase-D of the test bed development is ongoing. Vehicle integration has started at Thales Alenia Space Italy, Turin, to be ready for system tests in October. The schedule for the delivery of the parachute is being negotiated with the Russian supplier. Sufficient margin must be maintained for a launch in spring/summer 2011. Discussions with Russian authorities have secured a launch from a Russian submarine on a Volna rocket.

From ESA Bulletin Number 146 (May 2011)

Expert

Vehicle integration at the Thales Alenia Space Italy is progressing. Agreements to finance the European industrial subcontractors have been confirmed by Belgium, Austria, Switzerland, the Netherlands and Italy. Permission for launch is expected from Russian authorities in time for a mid-2011 launch.

Expert’s reentry flap endures hot baptism
 
29 June 2011

A spacecraft control flap designed for the super-heated hypersonic fall through Earth’s atmosphere has come through testing in the world’s largest plasma wind tunnel to be ready for its first flight next year.

The Expert capsule, studded with around 150 different sensors, is due to fly in spring 2012, sea-launched from a Russian submarine for recovery on Russia’s Kamchatka peninsula.

Expert Descent and Landing System Test Campaign

21 November 2011

http://www.esa.int/SPECIALS/EXPERT/SEMUIAZW5VG_0.html

Quote
The parachute test campaign was concluded successfully in October 2011 and the parachute subsystem is ready for integration with the Expert Vehicle.

Quote
Qualification tests:

- Parachute (Pilot, Drogue and Main) mock-up tests to develop the specific Expert system and packing,
- Static strength tests of the Pilot, Drogue and Main parachutes,
- Dynamic tests of the Pilot, Drogue and Main parachutes,
- Pilot parachute deployment tests using the pneumatic gun,
- Strength tests of the Pilot and supersonic Drogue parachutes using the pneumatic gun, and
- Main Parachute Drop Tests (6 in total), for the qualification of the Main Parachute strength and operations sequence.

Expert

The Qualification Review was concluded on 3 November for flight on Volna, its original launch system but, for various reasons, Volna might not be used as the launch vehicle. Meetings with launch service providers have been held to identify an alternative launcher. None of the systems (standard version) offer the atmospheric reentry conditions required, and additional analyses are needed to find launchers able to adapt to unconventional launch conditions. While waiting for a decision on the launch campaign, Expert will be kept in storage in a controlled environment at Thales Alenia Space Italy.

Studies are ongoing to identify alternative launchers in Russia (Kosmotras/Dnepr) and in the US (Orbital Sciences/Pegasus). A Technical Assistance Agreement with the US Department of State needs to be approved before discussion with Orbital Sciences can take place. Interest has been expressed by NASA centres in supporting the Expert launch operations and costs in exchange for the reentry data.

I'm sorry, but this makes me a little upset.
The USA has prohibited the exchange of space technology between the US and outer countries (I forgot the name of this law). And now NASA wants to help ESA (with doesn't need help with this small program) in exchange of ALL the scientific data (it's an reentry experiment after all).
Another times sorry, but as European citizen I hope ESA will make a deal with Kosmotras (with was the first plan). To let the US know they don't agree with steeling European technology, and thus  violating the US law when it benefited the US. Shame on you America!

You are referring to ITAR (International Traffic in Arms Regulations) that was intended to prevent the traffic in technologies that might be used to produce weapons. Over the decades since WWII the Europeans have benefited in uncountable ways from the free transfer of US developed technologies to them. If the United States signs an agreement to participate in an experiment that is not "steeling" (stealing). Why you think anyone should be ashamed doesn't make much sense to me.

Has the launch contract with Makeyev for the Volna launch been cancelled?

You have missed news that Russian Ministry of Defence are not going to give RSM-50 rocket for this launch so the contract can not be carried out.
