A set of tools to assist planetary scientists in the planning, acquisition and interpretation of observations of the ringed (and possibly-ringed) planets.
These forms enable you to generate a diagram showing the appearance of a planetary system at a specified time. Bodies and rings are rendered with terminators and shadows as appropriate. The viewpoint can be Earth’s center, a particular Earth-based observatory, or a spacecraft.
These forms enable you to generate a table listing useful information about the viewing geometry for a planet and/or any of its moons as a function of time. You are free to specify which of a variety of useful quantities to tabulate (e.g. RA and dec, phase angle, ring opening angle, distance, lunar phase, etc.).
These versions of the tools are intended to assist in the planning and analysis of Cassini data.
Saturn tools are updated regularly with the reconstructed Cassini tour.
