Visible in an unprocessed image from 36000 kilometers away, Prometheus’ 100-km long surface was revealed to have an interesting system of bulges, ridges, and craters. Cassini’s next major targeted flyby is of the moon Rhea. • antwrp.gsfc.nasa.gov ► Hong Kong Sky This remarkable scene combines multiple exposures recorded from a waterside perspective in Hong Kong, China.
