Summary form only given, as follows. In most space applications, the electrostatic probes move with the spacecraft relative to the ambient plasma. In low Earth orbit, the relative velocity ( approximately 8 km/s) is highly supersonic with respect to the ion-acoustic speed (0. For the typical value of V0 ( approximately 8 km/s) in low Earth orbit, the enhancement of the current through cross-field plasma transport was found to be an appreciable fraction of the current predicted by previous models, which do not account for cross-field plasma transport.
