Presents a theory concerning the orbital spacing of patterns in the solar system. The orbital distributions of the planets and major satellite systems are fitted with a Bode-type form. Accordingly, the Saturnian system requires vacant orbitals if the best fit is to have an accuracy comparable to that of other systems. (Author/GA)

This booklet describes the results of NASA's Viking spacecraft on Mars. It is intended to be useful for the teacher of basic courses in earth science, space science, astronomy, physics, or geology, but is also of interest to the well-informed layman.
