Format/Purpose:
The purpose of this Workshop is to bring together a large community to a) present DATA (Observations and laboratory measurements), b) describe their ANALYSIS and c) discuss the IMPLICATIONS in terms of origin and evolution of the surfaces of the moons in that order. An exception is made for the ‘astrobiology and planetary protection part’ which is scheduled on Tuesday afternoon for practical reasons.
This organisation implies that some talks may appear similar on the basis of their titles but in fact they cover different aspects. For example, faults are described ‘geologically’ in the first part of the Workshop, interpreted in the second one (what are the models that can explain the facts?) and used in the last one as a fundamental basis in the study of the evolution of the Europa surface or of the problems it involves in term of planetary protection.
The workshop is divided into short talks about specific subjects (around 20-25 minutes) and longer talks for general reviews of a given topic (30-40 mn).
Sessions are followed by discussions.
The main topics of the workshop are listed below:
