A self-consistent steady-state 2-D kinetic plasma solver has been applied to the problem of Langmuir triple-probe plasma diagnostic measurements in a flowing collisionless plasma. The triple-probe response is simulated for ion Mach numbers M = 0 - 5

Bare electrodynamic tethers have been proposed for two important space applications: in-orbit propellantless propulsion [1,2] and remediation of Earth-bound radiation belts through the scattering of high-energy electrons leading to their accelerated
