Recently, substantial progress has been made in the development of HgI2 detectors and associated electronics for space instrumentation. The many technical challenges in the instrument development involving spectroscopy performance, power consumption, weight, size, operation over wide ranges of temperature and ambient gas pressure, and others have been overcome. Descriptions of instrumentation under development such as: x-ray and alpha backscattering spectrometer, scanning electron microscope and particle analyzer, Mössbauer spectrometer, and gamma-ray spectrometer are given.
