oral

Description

"Remark : this scope of work has been first published for Dubai 2020 and partially treated in the Cyber Edition. As the Dubai edition of the IAC will provide an opportunity for real discussion, the topic is reconducted but please feel free to propose papers with open discussions". The space environment can strongly impact the performance and reliability of space missions. It has several natural and induced components, including high-energy radiation, plasma, atomic oxygen, planetary dust, extreme temperature, vacuum, micro-gravity, micrometeoroid and debris, molecular and particulate contamination, etc. Environmental conditions yield constraints at design phase, and important risks in the course of the mission. The evaluation of the nominal and worst-case conditions to be met, mitigation and protection options, and of their impact on missions and flight systems are thus of prime importance. This session will encompass the following topics: Space Weather, Plasma, Spacecraft Charging, Radiation, Atomic Oxygen, Planetary Dust, Molecular and Particulate Contamination, Plume Induced Contamination Effects and Interactions, Combined Environments - flight measurements; - physical processes; - prediction of nominal or worst case condition; - ground testing; - flight experiments and lessons learned; - modelling and prediction; thermos-optical degradation effects.
