The question of dwarf planet Ceres potentially being water rich is highly important for solar system science. A Herschel observation on 11 Oct. showed a clear detection of water absorption in Ceres spectrum, but only in H polarisation. An immediate reobservation ishere requested.

Mission Description
Herschel was launched on 14 May 2009! It is the fourth cornerstone mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
