Applications of Satellite Trajectory Optimizations Based on Displacement Damage Dose Deposition in Solar Cells S. R. Messenger, Northrop Grumman Mission Systems; C. A. Kluever, University of Missouri-Columbia
A model for optimizing spacecraft trajectories based on solar cell degradation has been developed. Comparisons with SCREAM demonstrate this method to accurately determine solar cell degradation for many Earth orbits and low-thrust transfers.

Using the Galileo Solid-State Imaging Instrument as a Sensor of Jovian Energetic Electrons A. Carlton, K. Cahoy, Massachusetts Institute of Technology; M. de Soria-Santacruz Pich, I. Jun, W. Kim, JPL
We develop a technique to quantitatively characterize the Jupiter high-energy electron environment using the Galileo spacecraft Solid-State Imaging (SSI) instrument and particle transport simulations in Geant4, finding agreement with the Energetic Particle Detector.

Experimental Evidence of Ground Albedo Neutron Impact on SER for Nanoscale Devices G. Hubert, L. Artola, DPHY, ONERA
The impact of ground albedo neutron on SER is investigated for nanoscale devices. Experimental evidence is investigated considering 45 nm technologies and neutron spectrometer. The impacts for ground applications are investigated using MUSCA SEP3 simulations.

Correlation of Single-Board Computer Ground-Test Data and on-Orbit Upset Rates from the Gaia Mission D. L. Hansen, R. Hillman, F. Meraz, J. Montoya, G. Williamson, Data Devices Corp.; E. Ecale, P. Paulet, P. Tatry, Airbus Defense and Space SAS; E. Serpell, ESOC, ESA
On-orbit SEU data for the DDC SCS750 single board computers used in the Gaia mission are analyzed for correlation to space weather. SEU had no effect on mission operation because of SBC error correction.
Methods for and the Influence of Uncertainty Propagation in the Solar Energetic Particle Environment Modelling (SEPEM) System P. Truscott, Kallisto Consultancy, Ltd., D. Heynderickx, DH Consultancy, A. Varotsou, TRAD, F. Lei, RadMon Research, P. Jiggens, ESA / ESTEC, I. Sandberg, Space Applications & Research Consultancy
Recent enhancements to the SEPEM solar proton/ion modelling system include the propagation of uncertainties in the model generation process. The method of this treatment is described and the relative importance of the contributions discussed.
