    Scientific Rationale

    The presence and distribution of water in asteroids is relevant to the origin and evolution of these objects, of our Solar System, and even of Earth's own water.  Water in asteroids has been detected in the form of hydrated minerals and recently as surface ice. The study of water and hydrated minerals in meteorites is equally exciting and relevant. This focused workshop will bring together the astronomical and meteoritic communities in a forum conducive to fruitful interactions.  

    There have been important recent developments in this topic. The tantalizing indication of water ice surviving in the Themis asteroid family (as suggested by the cometary activity observed in two asteroids belonging to this family) has been confirmed by the detection of surface ice on asteroid 24 Themis by two independent groups (Campins et al. 2010, Rivkin and Emery 2010).  In addition, water ice and organics have been reported on a second asteroid, 65 Cybele (Licandro et al. 2011).  The presence of ice on these two asteroids, particularly over a significant fraction of their surfaces, is puzzling because of the short lifetime for exposed water ice at these heliocentric distances (~3.2 and 3.4 AU, respectively).  Nevertheless, there are several possible sources for this unstable ice and identifying them is likely to be diagnostic of important processes on primitive asteroids.

    Some of the issues we can address during this workshop include:
