Title

Space Environment and effects on space missions

Description

The space environment can strongly impact the performance of spacecraft systems and science instruments, the reliability of space missions, and ultimately mission success. The space environment has several components, including high-energy radiations, plasma, atomic oxygen, planetary dust, extreme temperature, vacuum, micro-gravity, micrometeoroid and debris, etc. Environmental conditions yield constraints at the design phases, and risk mitigation in the course of the mission. The evaluation of the nominal and worst-case conditions to be met, and of their impact on mission science objectives, instruments and spacecraft systems/sub-systems are thus of prime importance. This session will encompass the following topics: Space Weather, Plasma, Spacecraft Charging, Radiation, Atomic Oxygen, Planetary Dust, Interactions with Planetary Exospheres and Plumes, Combined Environments, Physical Processes, Modelling and Prediction, Risk Mitigation, Ground Testing, Flight Measurements, Flight Experiments, In-Flight Anomaly Resolution and Lessons Learned.
