CheshireCatCO writes "When Cassini makes its closest approach (50 km) during the flyby of the moon Enceladus next Monday 11 August, the spacecraft will be zipping by too quickly to turn and image in the usual way. So the Cassini team will be trying something new: a 'skeet-shoot' of the surface. The spacecraft will start to spin before the closest approach to the south pole so that when the best resolution is possible, the moon will drift through the field of view slowly enough to acquire unsmeared images. Of interest are the eruption-sites on the surface that give rise to the plume extending thousands of kilometers into space and producing Saturn's E ring. This flyby will be optimized for the imaging instruments (ISS, VIMS, CIRS, and UVS) in contrast with the March flyby, which was designed for the fields-and-particles instruments."
