Interaction of Earth’s upper atmosphere and space environment with spacecraft: processes that affect atmospheric density relevant to spacecraft orbit decay; basic composition and structure; radiation and radiative transfer; atmospheric energy balance; atmospheric chemistry and ion production/loss mechanisms; fundamental concepts of Solar-terrestrial physics including ionospheric Chapman theory; atmospheric energy/mass transport; ionospheric electrodynamics; ionospheric storms; planetary atmospheres/ionospheres; instrumentation
The Earth’s upper atmosphere/ionosphere forms the inner boundary of the space environment and is the region where the majority of spacecraft reside. As society becomes increasingly dependent on technologies embedded in this environment it is imperative to develop improved understanding of its physical properties and dynamics during extreme disturbances produced by changes in solar activity. This course covers composition, structure, and dynamics of the upper atmosphere/ionosphere system and how it responds to external forcing from the solar wind and magnetosphere. These concepts are key to understanding how the interaction between this region and spacecraft can change over time. Students with such training will be better equipped to pursue career opportunities at aerospace corporations or other entities affected by or interested in the near-Earth space environment. This course is offered at the 4000 level because it requires prior knowledge of physical applications of vector calculus related to fields, such as fluid mechanics covered in AOE 3014 or electromagnetism covered in ECE 3105. To ensure success in AOE 4674 (ECE 4174), students should have learned concepts of vector calculus related to fields, flux quantities and potentials.
