Research activities carried out as part of cooperative agreement 926 are summarized. A portable, field deployable X-ray diffractometer-spectrometer was developed that can analyze rock surfaces and loose granular materials without the need for sample acquisition or preparation. The device was deployed on the Russian Marsokhod rover at the NASA Ames Research Center. Techniques and technological innovations were developed that provide the basis for a new kind of X-ray source. In the area of x-ray analysis techniques, artificial diffraction spectra were created to determine how complex mineral mixtures can be analyzed by diffractometry when only broad fingerprint patterns emerge from the analyses. USML-2 tapes were analyzed. A preliminary, but successful computer code was developed to simulate the behavior of agglomerating granular matter as it may occur in martian dust storms. The model is based on dipole-dipole interactions. In the area of aeolian comminution, using a particle impelling crossbow device , it was possible to elucidate the processes involved in reptation sand transport likely to occur on Mars and Earth. A theoretical model was developed that relates the microscopic cratering mechanisms during saltation-reptation to the megascopic impact processes caused by meteorites. Abstracts of two conference papers as well as five short articles published or submitted for publication are included as attachments.
