One of the important outcomes of the meeting should be to assess the confidence with which we can evaluate the probability of presence of water on planets and satellites in the Universe, and from where that water originates. It should also provide us with indications on the most important directions for future works, and on the contributions we can expect from future space and ground-based observing facilities. As usual, the main findings of the workshop will be presented in a new dedicated volume of the Space Science Series of ISSI (see www.issibern.ch/publications) and Space Science Reviews, jointly prepared and written by the workshop participants. All papers will be peer reviewed, and the volume is expected to appear about 12-18 months after the workshop.
