"Cassini focused its cameras and other remote sensing instruments on Enceladus with an emphasis on the moon's south pole" says a NASA press release, "where parallel stripes or fissures dubbed 'tiger stripes' line the region. That area is of particular interest because geysers of water-ice and vapor jet out of the fissures and supply material to Saturn's E ring."
"Two more Enceladus flybys are planned for October," notes the NASA release. "The first of those will cut Monday's flyby distance in half and bring the spacecraft to a remarkable 25 kilometers (16 miles) from the surface." A resolution of 3.7 meters per pixel should be achieved.
