TL;DR: The Mars Express high-resolution stereo camera (HRSC) as discussed by the authors is a push-broom scanning instrument with nine CCD line detectors mounted in parallel on a focal plane, its unique feature is the ability to obtain near-simultaneous imaging data at high resolution, with along-track triple stereo, four colors and five different phase angles.

TL;DR: Images acquired of Saturn's rings and small moons by the Cassini Imaging Science Subsystem have produced many new findings, including new saturnian moons; refined orbits of new and previously known moons; ring particle albedos in select ring regions; and never-before-seen phenomena within the rings.
Journal ArticleDOI

TL;DR: The Cassini Imaging Science Subsystem acquired high-resolution imaging data on the outer Saturnian moon, Phoebe, during Cassini's closeFlyby on 11 June 2004 and on Iapetus during a flyby on 31 December 2004.
Journal ArticleDOI

TL;DR: From analysis of cloud motions through early October 2004, vertical wind shear in Saturn's equatorial jet and a maximum wind speed of ∼375 meters per second are reported, a value that differs from both Hubble Space Telescope and Voyager values.
