The ISECG is a committee of the space agencies to coordinate the planetary exploration. It is our intention to organise an open, Town Hall type, meeting about Mars and, more in general, planetary terrestrial analogues. Last year another meeting has been organised at the LPSC. I discussed this matter with the Chairpersons Manuel Grande and Maria Teresa Capria and they are supporting the proposal. We ask for a 3 hours slot due to the particular function of this meeting and the international support at high levels (space agencies)
