Astrobiology eXploration at Enceladus (AXE): A New Frontiers Mission Concept Study Open
The Saturnian moon Enceladus presents a unique opportunity to sample the contents of a subsurface liquid water ocean in situ via the continuous plume formed over its south polar terrain using a multi-flyby mission architecture. Previous an…

How Predator-Prey Dynamics Creates ‘Straw’ in the Strongest Density Waves Open
<p>The Cassini cameras detected elongated structures in Saturn&#8217;s ring in highly perturbed regions near ring edges and within the strongest density waves. These &#8216;straw&#8217; features are likely triggered by th…

Shape and compression of self-gravity wakes in Saturn’s rings Open
<p>The varying geometry of Cassini star occultations by Saturn&#8217;s rings constrains both the size and shape of structures that block starlight. Statistics of UVIS star occultations measure structures as small as meters, on ti…

Characterizing self-gravity wake morphology in Saturn’s rings from Cassini UVIS stellar occultation statistics Open
 Cassini’s Ultraviolet Imaging Spectrograph (UVIS) observed 276 stellar occultations of Saturn’s rings over the course of its mission. During these occultations, UVIS’ High-Speed Photometer (HSP) collected photon cou…

Sizes of Particles, Clumps, and Gaps Within the Strong Janus 2:1 and Mimas 5:3 Density Waves from Cassini UVIS Stellar Occultation Data Statistics Open
The high-speed photometer of Cassini’s Ultraviolet Imaging Spectrograph (UVIS) collected data from stellar occultations across Saturn’s rings at unprecedented high resolution over a wide range of viewing geometries. Because pho…
