Abstract:

This paper describes the ionosphere direct measurements satellite Explorer VIII, with emphasis on the physics of the experiments designed to measure electron density RF impedance probe, electron temperature electron temperature probe, positive ion concentration ion current monitor, and ion mass retarding potential probe. Experiments were also performed which measured the momentum, energy, and spatial distribution of dust particles. Experimental data presented are typical of that processed to date. Methods used by systems engineers to fulfill the special requirements imposed by the scientific experiments upon the over-all satellite design are described and data such as the satellites thermal and spin-decay history are reported. Of interest to spacecraft technologists concerned with the influence of the earths magnetic field are measurements on effects of potential differences at various points on the satellite surface. A method for determining satellite aspect is also introduced. Author
