Spacecraft wakes is the disturbed region created behind a spacecraft traversing a plasma environment, characterized by significant depletion of plasma density, perturbed electric fields, and altered particle distributions compared to the ambient conditions. This academic concept and research area investigates the complex physical processes driving these perturbations, including plasma collection, charge separation, and wave generation, and their dependence on spacecraft geometry, potential, and ambient plasma properties. The study of spacecraft wakes is significant for understanding and mitigating effects on onboard instrumentation, spacecraft charging, and interactions with space debris, contributing fundamentally to space plasma physics.
