## COURSE OVERVIEW

## Astronautics involves the study of manned and unmanned spaceflight. Orbit mechanics, often referred to as astrodynamics, is the branch of astronautics dealing with the motion of a spacecraft under the influence of gravitational forces, atmospheric drag, etc. In this course, we will first review the characteristics of the motion of a system of particles with focus on the two-body problem which is a good approximation for the motion of a low-Earth orbiter. Then emphasis will be shifted to orbit transfer, basic rocket dynamics, interplanetary mission analysis, and perturbation due to atmospheric drag and Earth oblateness. You may be asked to solve a problem with Satellite Tool Kit (STK) and verify the solution and/or use data generated by STK in a follow-on application.

## Class Format

Twice-weekly lectures.

Weekly reading assignments.

Weekly in class quizzes: reading and lecture. Reading quizzes are to test if students complete the reading assignments before the class. Lecture quizzes are to test if students understand the materials discussed in classes for the previous two weeks. Quizzes are to be completed individually. Any type of collaboration or copying on a quiz constitutes cheating and will result in a zero grade for the quiz. A repeated instance of cheating will result in an F for the course and will be reported to student Honor Code Office.

Homework will be assigned every other week. No late homework will be accepted. Collaboration with others on homework is acceptable, but line-by-line copying of someone else's homework is cheating, and will result in a grade of zero for that assignment. A repeated instance of cheating will result in an F for the course and will be reported to student Honor Code Office.
