One of the primary objectives of the cooperative NASA/Air Force Spacecraft Charging Investigation is to ensure that validated analytical models and test techniques are available for the assessment of spacecraft interactions with the space environment. Models must be capable of predicting the degradation (permanent damage or anomalous behavior) of spacecraft due to the environment. Also, test techniques must be developed for the purposes of providing input data for the models, or for certifying that the spacecraft fulfills its design requirements. This report is an update to the Model Validation/Test Evaluation Status Report (CDRL 006A2) submitted August 1979 by SAI. In the past year, p78-2 data have been integrated into an environmental Atlas. NASCAP predictions have been compared with the P78-2 SSPM sample measurements. Two major electron spraying experiments have been conducted on geometric spacecraft models for which coupling predictions have been made. A quasi-static model of the SGEMP code SABER has been developed and exercised, and significant work has been reported on the emission of current during discharges.
