Covers the principles and governing equations fundamental to the design, launch, and operation of artificial satellites in Earth's orbit and beyond. Material includes the vis-viva equation; the rocket equation; basic orbital maneuvers, including Hohmann transfers; bielliptic trajectories, as well as spiral transfers; the link budget equation; spacecraft power and propulsion; thermal equilibrium and interactions of spacecraft with the space environment, such as aerodynamic drag; electrostatic charging; radiation; and meteorids. Spacecraft are initially treated parametrically as point masses and then as rigid bodies subject to Euler's equations of rotational motion. Serves as a prerequisite for more advanced material in satellite engineering, including the technological implementation of various subsystems. Lectures are offered in a hybrid format, in person and remote.
