AB: In connection with the observations of Cassini in its
encounter with Enceladus, we are studying the thermal and
radiation stability of ammonia-water mixtures in the
laboratory. We use microbalance, mass-spectrometry, and
infrared-spectroscopy to follow the evolution of the ices,
and measure the sputtering and the sublimation
rates. The results will be related to the spacecraft data
that is currently being processed.
