Steven Nerem (Office: ECAE100, Ph , nerem@colorado.edu) Class Time TTH 11:00 12:15 Class Location Class Web Page Office Hours Class Assistant Required Text Grading ECCS 1B12 TTH 9 10:30 AM, or by appointment, or by Tom Jakub (ECNT 414, jakub@colorado.edu) Foundations of Astrodynamics and Applications, 2 nd Edition, 2001, by David A. Vallado Take Home Mid-Term (25%) Take Home Final Exam (25%) Homework (30%) Research Project (20%) Late homework deducted 10 pts for each day late! ALL due dates for CAETE students is one week later = A, = B, = C, = D, < 60 = F Homework Important Dates Homework will be assigned on roughly a weekly basis. While the calculations can be done using whatever software you prefer, I highly recommend using Matlab. If you are unfamiliar with Matlab, check out While you may discuss ideas and questions about the homework with other classmates, the homework solution must be your own. October 13 No Class Fall Break October 18 Take home midterm exam due 10/25 November 25 No Class - Thanksgiving December 8 Last Day of Class, Take home final exam Course Overview In this course we will study the kinematics and dynamics of celestial bodies and artificial satellites moving under the influence of forces common to the space flight environment; most importantly bodies moving under the influence of gravity.

2 Other Notes: 1) If you qualify for accommodations because of a disability, please submit to me a letter from Disability Services (DS) early in the semester so that your needs may be addressed. DS determines accommodations based on documented disabilities ( , Willard 322, 2) Every effort will be made to accommodate students who, because of religious obligations, have conflicts with scheduled exams, assignments, or other required attendance, provided they notify me well in advance of the scheduled conflict. 3) As a result of extensive discussions with and recommendations from faculty and students, a new classroom behavior policy and associated new procedures have been adopted. You may wish to read this information which is also at: ( 4) The new Student Honor Code system has now been implemented in all schools and colleges. You can see the honor code information at (
