We propose to observe a 5x5 oversampled map wavelength centered on the 69micron band of crystalline silicate forsterite for the Planetary Nebula NGC6543. This will be the first time that we can resolve the location of crystalline dust in a mass-loss outflow. This will help is investigate the dust-formation in the circumstellar environment of an evolved star and look at the link with mass-loss and possibly binarity.The total observing time is 3.87h

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.
