Literally a week away from Europe's first attempt at aerobraking now?
Yep after ME SC bus was determined to not be strong enough for traditional aerobraking and the fact the ME was a quickly built to re fly the Mars-96 instruments.

Venus Express was the first european probe that performed aerobraking manoeuvres.

UPDATE: An interesting event:

http://www.ph.ed.ac.uk/events/2017/73525-the-exomars-trace-gas-orbiter-mission-to-mars-and-the-search-for-signs-of-life

 The ExoMars Trace Gas Orbiter mission to Mars and the search for signs of life

    Event time: 1:30pm until 3:00pm
    Event date: 14th March 2017
    Speaker: Dr. Manish Patel (The Open University)

Searching for signs of life beyond the Earth is a one of the primary aims of space exploration.  The ExoMars Trace Gas Orbiter (TGO) is a mission to Mars, which seeks to answer this question.

TGO is a joint European-Russian mission to explore the atmosphere of Mars from orbit, and demonstrate Europe’s ability to land a spacecraft on Mars for the first time.  The mission launched in March 2016, with Mars arrival and ‘landing’ on 19th October 2016.  Investigating trace gases in the atmosphere is the primary purpose of the mission – gases such as methane, and ozone.  Methane is a particularly interesting gas, in that its variable presence in the atmosphere of Mars is not expected; on Earth, the majority of the methane in the terrestrial atmosphere is produced by life.  Hence, its presence on Mars opens up a tantalising possibility that this trace gas may be a sign of the presence of (past or present) life on Mars.

The Open University co-leads one of the methane hunting instruments (called NOMAD).  Here, I will present the mission and its background to you, and update you on the latest status of the mission and the results to date from the orbiter and the fate of the lander.

Happy birthday, ExoMars! Today we mark one year since launch!

Are there many results given that it isn't in its science orbit yet?

I suppose today they may show us some new pics, some few graphics just to demonstrate the power of their instruments - but nothing more.

Deimos Space Planetary Entry Toolbox (PETBox) for Mission Engineering and the related design methodology for Atmospheric Flight are now Flight Qualified in both Earth and Mars

Schiaparelli separated from the Trace Gas Orbiter (TGO) on October 16th 2016 and reached Mars three days later. It performed a nominal hypersonic entry with a pre-defined flight path angle, decreasing its velocity until reaching subsonic regime under the parachute. During the descent phase an anomaly occurred, and the demonstrator module separated from the backshell earlier than expected, compromising the landing phase. During the whole EDL mission, Schiaparelli was able to communicate with the TGO and with the Mars Reconnaissance Orbiter, transmitting its real time on-board telemetry. The data collected is extremely valuable for the preparation of the 2020 mission.

The post-flight results have contributed to the validation of key technologies and design tools, including the Deimos Space Planetary Entry Toolbox (PETBox) for Mission Engineering and the related design methodology for Atmospheric Flight. As a result, these self-developed technologies  are now Flight Qualified for missions in Earth (through the successful ESA IXV mission) and Mars.

Deimos Space has been involved in ExoMars since 2004, carrying out technical activities in the Mission Engineering and Guidance, Navigation and Control domains for more than 12 years. This high commitment to the ExoMars programme has allowed the company to be the first organisation to submit a paper about ExoMars 2016 Post-Flight analyses to international conferences. The results of these studies will be showcased in detail at the upcoming 14th International Planetary Probe Workshop (The Hague, The Netherlands) and International Astronautical Congress 2017 (Adelaide, Australia).
