SBQ401: Fundamentals of Orbits and Getting into Space

Course details

Summary
  • Learn the principles of rocketry, the designs in use today, and the essentials of different orbits and how rockets reach them.

Description

To engage in the business of space, you need to have a general understanding how orbits work and how spacecraft get from earth into their designated orbits. We will not go into any mathematics or technical detail, but you will get an overview of:

  • The basics of rocketry: what rockets do and how they do it.
  • Examples of the various types of rocket that enable the space business today.
  • Principles of orbits: how spacecraft move once they are launched into space, and why some orbits differ from others.
  • What rockets need to do to get spacecraft into their proper orbits.
