    A series of experiments on 0.158μm PMMA spheres suspended in an index matching mixture of decalin and tetralin in the microgravity environment are conducted. Light scattering are used to probe the static structure and the particle dynamics. Results suggest that colloidal crystal growth is profoundly affected by gravity in unrecognized ways. It is believed that the Random hexagonal Close Packed structure is related to the nonequilibrium growth that is evident from the presence of dendrites. An analysis of the dendritic growth instabilities is presented within the framework of the Ackerson-Schatzel equations.
