We are interested in the hot low density plasmas surrounding planets, stars, and other astrophysical objects. Our direct measurements have revealed a rich variety of phenomena in these plasmas. We use the data from a number of different spacecraft in the development of models and the construction of theories to help understand the behavior of the particles and fields. Current experimental efforts include the development of a test particle method of measuring electric fields and the construction of a digital camera for spectrometry of faint objects.
