This sequence of 12 frames was taken by NASA’s Cassini spacecraft over a span of about 45 minutes on March 12, 2008. In that brief time, Cassini covered almost 40,000 kilometers in its approach to a flyby encounter with Enceladus, one of the moons of Saturn. The overexposure and smearing of the images gives a hint of the raw speed involved – 14.4 km/sec (or 32,211 mph). Shortly after this sequence, at its closest, Cassini approached within 52 km (32.3 miles) of the surface of Enceladus. (NASA/JPL-Caltech)
