12/1 The final flow for the final 2 weeks of class has been rearranged as reflected in the topics below. We will finish up with food and waste tomorrow, then I want to cover the basics of crew and payload accommodations and EVA systems. We’ll wrap up by focusing on the integration aspects related to the other primary spacecraft subsystems.

11/13 Exam 2 Review Notes

11/4 HW 2 Assignment (due 11/11, CAETE add one week as usual) and BVAD Reference Document

10/23 Note that we are switching to the Eckart textbook in addition to the H-SMAD for the next few weeks.

9/14: Exams are now indicated in the syllabus outline below. The dates are set, but topics may still be modified / rearranged a bit. CAETE students, add one week.

9/8: We’ll pick back up tomorrow where I left off on Lecture 2, then get back on track. Please read through Chapter 1 before class.

8/29: In my absence next week, Joe Tanner, NASA Astronaut, and Kevin Higdon, PhD student will be giving lectures that will provide background on the Constellation Program. No notes are posted for these. Please read through Chapters 9 and 10 before Kevin’s lecture on orbits and propulsion before Kevin’s lecture on Thursday.

8/27: I will periodically post current messages here in red, with the text grayed out as events pass, so be sure to check for announcements as you open the web site to download the lecture note outlines. Notes for yesterday’s and tomorrow’s lecture are posted now, see links below.

Note: As of Fall 2008, ASEN 5158 Space Habitat Design has been modified to incorporate the material previously covered in ASEN 5116 Spacecraft Life Support Systems. As such, ASEN 5158 still deals with the wide breadth of human spacecraft subsystem design requirements as before, but also now goes into depth on the life support specifics that were previously only addressed in ASEN 5116. Both classes used to be essentially half lecture-based and half group project-based. Under this reorganized flow, however, the combined comprehensive lecture material has now all been rolled into ASEN 5158 with the project experience following as a separate MS Projects or Independent Study course listing.

Course Objectives

Utilizes systems engineering methods for designing a spacecraft intended for human occupancy and provides a functional knowledge of the technologies used to sustain life. Emphasis is placed on deriving requirements from stated mission objectives, developing integrated vehicle schematics, and comparing design options by trade study.
