Course Objectives 

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

Office Hours: weekly in design team group meetings, or ‘drop in’ is ok if my door is open, or by appointment if requested
