Abstract

The Floating Potential Probe (FPP) operated on the International Space Station (ISS) from December 2000 to April 2001. During that time, it took many measurements of the ISS floating potential and the low-Earth-orbit electron density and temperature. Those measurements were used as inputs to the Environment WorkBench (EWB) model of ISS potentials (originally developed by the Science Applications International Corporation for NASA, but now sometimes called the Boeing Plasma Interaction Model), which is used even today to predict charging levels for ISS. FPP is now completely defunct, having been re- moved and jettisoned from ISS. With the advent of the new floating potential measurement unit (FPMU) on ISS and the beginning of ISS operations with three large sets of solar array panels instead of just one, a review of FPP measurements can offer comparisons with the new FPMU data and perhaps improve the accuracy of future ISS charging predictions. In particular, FPP measurements during times of low electron temperature and high electron density (the times of worst ISS charging) will be brought forward for comparison with the newly obtained FPMU data.
