Terry Hurford is a planetary scientist in the Geology, Geophysics and Geochemistry Laboratory at NASA GSFC. He studies the geology and geophysics of icy satellites. His work has linked the formation of tectonic features to tidal stresses that are active on these bodies. For example, on Enceladus his work has led to the understanding that diurnal changes in stress can modulate the on-going eruption of material from fractures called Tiger Stripes in the south polar region.
