Describes a course, without laboratory, using rudimentary algebra and covering such topics as gravitation, orbital mechanics, atomic structure, geomagnetism, electromagnetic spectrum, theory of relativity, extraterrestrial life, and interstellar travel. (GH)

Describes a dynamical system which is stable at potential maxima. The maxima, called L-4 and L-5, are stable locations of the restricted three-body problem. Energy loss from the system will tend to drive it away from stability. (GA)

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)

Describes a course using the prospect of living in space for motivating students to learn basic physics as well as differences between pure science and technology. Includes course content and a sample final examination. (Author/JN)
