Plasma Interactions with Spacecraft
Abstract
The objective of this contract is to develop, incorporate, test, and validate new algorithms for Nascap-2k that are needed to self-consistently compute plasma transport and to model electromagnetic radiation in the near-to mid-field from VLF (3 kHz to 30 kHz) antennas. The plasma flow models can be used to address various plasma engineering concerns including surface discharges due to meteoroid impact and spacecraft contamination due to electric propulsion plasma plume effects. The goal of this effort is to provide a plasma engineering capability to the spacecraft community. During the first two years of this contract, progress was made on Nascap-2k development, particularly charging with time-dependent bias values, macroparticle splitting and injection, and algorithm development of charging with tabular spectra generated by magnetospheric models.
