Campins, Humberto - Water and Organic Molecules on Asteroids and on Earth

The detection of water ice and organic molecules on of asteroids 24  Themis and 65 Cybele were reported in 2010 and 2011, respectively.  Infrared spectra of these asteroids indicate that the ice and organics  are widespread on their surfaces. In addition, water vapor was recently discovered emanating from asteroid 1 Ceres.  These discoveries have important implications on current views of primitive asteroids, the dynamics of the early Solar System, and the delivery of water and organic molecules to Earth.  They are also relevant to several space missions, including Dawn, Gaia, Hayabusa 2, OSIRIS-REx and WISE.
