Course Summary

This is the most comprehensive short course on spacecraft design available. Attendees are exposed to an extensive and coherent treatment of the fundamental principles involved with the interdisciplinary design of spacecraft. Besides the engineering associated with the design of the spacecraft itself, the course also covers history and current spacecraft, details on the launch and orbital environments, the principles of orbital mechanics, and types and operations of onboard payloads. It also includes descriptions of all types of spacecraft testing, failures, reliability, and lessons learned, and the economics of spacecraft. The course provides many illustrative examples along with more than 60 short videos and animated diagrams as well as hardware “show-and-tell” samples and models to demonstrate important concepts. The flow of the course is shown below:

“I again wanted to say that I really enjoyed your class and recommended to my management that all of our new hires should take such a class.  It is certainly very useful to see your own area in the context of the entire space picture.” C.S., Senior Engineering Specialist, Aerospace Corp.

“Excellent course for people like me who wish to go into program management.” M.R., Engineer, Boeing Houston

“This course was great. Instructor was able to simplify but not talk down to audience. He explained all terms likely not to be understood.” Anonymous.

“Thanks! This was a great course. I especially liked the launch vehicle section and some of the communication and CDHS stuff.” Anonymous.

“The course was both enjoyable and very thorough. Having the slides available for additional notes was very helpful. Great course!” Anonymous.

What You Will Learn

How to specify the design requirements of a spacecraft, based on mission operations and orbital mechanics dictated by the launch vehicle. Loads environment on spacecraft from transportation to launch to on-orbit. You’ll be introduced to orbital mechanics and understand the reasons different orbits are used to carry out missions. You’ll learn about payload selection and design and the differences between direct- and remote-sensing payloads. You will see how the payload’s properties are used to obtain a first estimate of the spacecraft’s dry mass, power consumption, and volume. The spacecraft’s CONOPS (concept of operations) is used along with an understanding of rocket propulsion to obtain the required propellant mass so that the “wet” or loaded spacecraft mass can be found. With this, the course looks in detail at the eight subsystems: mission design, structure, propulsion, power, thermal, attitude control, telecommunications, and command and data handling. Each is discussed in detail and the course shows how to estimate the mass, power, and volume requirements of each. You will be introduced to spacecraft stowed and deployed configurations and their structural designs. You’ll be introduced to the details of vibration, shock, acoustic and thermal loads during launch and on-orbit. You will learn about guidance and control systems and how they differ based on configurations and missions. You’ll be introduced to manufacturing techniques as well as testing, reliability, and cost estimating. Throughout the process, you will be provided key design recommendations and rules of thumb, “sanity checks” for calculations, and will learn why things are ‘done the way they are.’ At the completion of this course, you will have been introduced to the complete process of spacecraft design and operation and will be able to “speak space,” understand many technical papers and presentations, and communicate with others in the space industry.
