In November 2004, the existence of a potential low-altitude Tethys flyby ... NASA Center: Jet Propulsion Laboratory Publication Year: 2005 Added to NTRS: 2007-12-07 Document ID: 20070034997 Control of node crossings in Saturnian gravity-assist tours Author(s): Strange, Nathan Abstract: In the Saturnian system, the control of the node-crossing point is important to avoid debris in Saturn's ring plane and to target flybys of moons other than Titan. This paper describes how to use gravity assists to control ...
