Open discussion on the current description and situation of Exomars. The main questions to be debated could be :

- What are the main scientific questions which should be addressed by the ExoMars mission?
- Which minimal science should be kept in the case of budget cuts, for both the 2016 and 2018 missions?
- What science should be foreseen besides ExoMars (ex: seismology) and beyond ExoMars (Mars sample return) and how to implement it?
-... any other question...
