The problem of the ion density distributions around a charged satellite has been treated by a numerical method which does not require linearization of the equations or restriction to infinitesimal objects. However, magnetic field effects were not considered, and a number of other simplifying assumptions were required. Some sample calculations for spherical satellites are presented, illustrating the general character of the satellite wake. Calculations of the so-called charge drag were also made, yielding results qualitatively similar to those previously obtained by Jastrow and Pearse (J. Geophys. Res. 62(3):413-423, 1957). (Author).

The interaction of a satellite with the ionosphere is studied by solving numerically the Poisson-Vlasov system of equations. The self-consistent electric field is obtained by means of an iteration technique which cycles between the ion density and potential calculations. The current-voltage characteristics are computed as functions of satellite velocity, ion mass, electron temperature, and satellite shape and size. The size of the satellite studied varies over a range extending from 0.2 to 25 Debye lengths. The floating potential and the plasma drag of the satellite are obtained. In addition, the angular distribution of the ion current to a cylindrical satellite is obtained. The detailed structure of the wake is investigated. In particular, the wake length and ion focusing in the wake are studied. The satellity interaction with the ionosphere is examined without the effect of an ambient magnetic field. This interaction is then restudied by considering the inclusion of a uniform magnetic field. It is shown that a magnetic field oriented parallel to the flow velocity has a much greater influence on the subsequent motion of the ions in the wake than a field of equal magnitude oriented perpendicular to the flow velocity.

International Series of Monographs in Aeronautics and Astronautics, Volume 18: Interactions of Space Vehicles with an Ionized Atmosphere focuses on the interaction of bodies with ionized gas as it move through the interplanetary space. This book is divided into 10 chapters. Chapter 1 deals with the fundamental problem that underlies the distortion of a plasma in the vicinity of an electrically charged body. The rocket and satellite measurements of the plasma that sheath around the body in which the screening takes place are discussed in Chapters 2 to 4. In Chapters 5 to 6, the direct physical interactions between the particles of the plasma and surface of a body are described. The electromagnetic propagation effects introduced by the presence of a body in a plasma are covered in Chapters 7 to 9. The last chapter is devoted to finding and describing mechanisms that might explain the existence of plasma clouds produced by the passage of large bodies through a plasma. This volume is intended for scientists, engineers, and researchers interested in the interactions of space vehicles with an ionized atmosphere.

This book will explore the fundamentals of spacecraft charging: why it occurs, when it occurs, where it occurs, how to measure it, and its side effects. It will discuss state-of-the-art spacecraft charging technologies, which will be explained in detail and with pedagogical emphasis. Exercises for further learning will be included to facilitate a deeper understanding of the material. It will be of interest to advanced undergraduate and graduate students, in addition to researchers working in physics and engineering keen to understand more about spacecraft interactions with space plasmas. Key Features: Translates complex terminology into accessible language Authored by experts in the field Provides worked examples and exercises for further learning

A Spacecraft Charging Technology Conference, sponsored by the USAF and NASA, was held in October 1976. The Proceedings contain over 50 papers dealing with subjects including: (1) the geosynchronous plasma environment, (2) spacecraft modeling, (3) spacecraft materials characterization, (4) spacecraft materials development, (5) satellite design and test. In addition, an executive summary and the transcript of a panel discussion are included. (Author).
