Prospecting for lunar ice using a multi-rover cooperative team

Description: A multi-rover cooperative team or swarm developed by Sandia National Laboratories is described, including various control methodologies that have been implemented to date. How the swarm's capabilities could be applied to a lunar ice prospecting mission is briefly explored. Some of the specific major engineering issues that must be addressed to successfully implement the swarm approach to a lunar surface mission are outlined, and potential solutions are proposed.

The structure and dynamics of amorphous and crystalline phases of ice

Description: The structures of the high and low-density amorphous phases of ice are studied using several techniques. The diffraction patterns of high and low density amorphous ice are analyzed using reverse Monte Carlo methods and compared with molecular dynamics simulations of these phases. The spectra of crystalline and amorphous phases of ice obtained by Raman and incoherent inelastic neutron scattering are analyzed to yield structural features for comparison with the results of molecular dynamics and R… more

Experimental constraints on the chemical evolution of icy satellites

Description: The inferred internal structure of large icy satellites hinges on the degree to which their rock component has been hydrated: this is due to the low density of hydrated silicates relative to anhydrous silicates. Accordingly, interior models of icy satellites have varied greatly in their estimates of ice thickness due to uncertainties in the density of the underlying rock. Furthermore, as both H{sub 2}O (potentially liquid) and organic materials are likely to be present, icy moons have been post… more

Development and Testing of a Short-Wave Radiation Model for Interpreting ARM Data. Final Report for Period January 15, 1997 - March 15, 2000

Description: A research program devoted to improving the understanding of atmospheric radiation processes has been supported by DOE ARM grants with Prof. Qiang Fu as the Principal Investigator. This final report summarizes our research efforts, which emphasizes the findings and their significance to the solar radiative transfer in clear atmospheres, the effects of 3-D cloud fields on the solar radiative energy budget, a better understanding of radiative properties of nonspherical ice crystals, and parameter… more

Ice slurry cooling research: Microscale study of ice particles characteristics, role of freezing point depressant, and influence on slurry fluidity

Description: The influences of freezing-point-depressants on ice slurry characteristics in the form of ice slurry fluidity and on the microscale ice particle features are studied. The results identify microscale features of ice particles such as surface roughness that greatly influence slurry fluidity that are altered favorably by the use of a freezing point depressant. The engineering of a workable and efficient ice slurry cooling system depends very strongly on the characteristics of the individual ice pa… more
