Abstract
Nascap-2K is being developed under sponsorship of the US Air Force Research Laboratory and NASA’s Space Environment Effects (SEE) program. It replaces the twenty-five year old NASCAP/GEO code, along with other aging spacecraft plasma interactions codes such as NASCAP/LEO and POLAR. Nascap-2K includes an interactive Object Toolkit (OTk) for spacecraft surface definition, uses a newly developed Boundary Element Method (BEM) treatment for surface charging, and uses advanced numeric techniques developed for the DynaPAC code for external potentials, charge densities, and particle trajectories. In this paper we give a brief description of the interface and some of the numerical techniques, and show simulation results for a geosynchronous satellite (DSCS-IIII), a satellite in the Solar Wind (STEREO), and a satellite in Mercury orbit (MESSENGER).
