SESSION IIIUnderstanding near-Earth space and atmospheric effects are critical to satellite designand effective on-orbit operation of spacecraft and payload systems (including RF andscientific payloads). Atmospheric density impacts Orbital Determination (OD) in theLow Earth Orbit (LEO) regime. Ionospheric and proto-ionospheric physics result in RFsignal delays and scintillation. The spacecraft in-situ environment will drive on-orbitimpacts that include electrostatic discharge events, single-event upsets and other effectsresulting from trapped radiation and other solar particle events. This session will includea tutorial of the current state of space and upper-atmospheric physics and providean overview of its impact to orbital missions.National Chairpersons:Tim WalshNational Oceanic andAtmospheric Administration –Goddard Space Flight Center(NOAA/GSFC)Bob RutledgeNational Oceanic andAtmospheric Administration –Space Weather PredictionCenter (NOAA/SWPC)Doug BieseckerNational Oceanic andAtmospheric Administration –Space Weather PredictionCenter (NOAA/SWPC)Local Chairpersons:Shawn McQuerryLockheed MartinSpace Systems CompanyLee BarkerLockheed MartinSpace Systems CompanyThe following papers were not available:AAS 12-031“Introduction to Space Weather,” Bob Rutledge, NOAA/NWS (Presentation Only)AAS 12-032“Space Weather Considerations for Spacecraft/Instrument Design,” Paul Richards,NASA/GSFC (Presentation Only)The following paper numbers were not assigned:AAS 12-036 to -04011
