This module is intended for anyone interested in pursuing in more detail the space part of aerospace engineering. It looks at each of the key subsystems of a spacecraft in detail. It also introduces the overall theme of space systems engineering by emphasising the interfaces between subsystems and the iterative nature of spacecraft design and spacecraft systems engineering.
Aims and Objectives
Knowledge and Understanding
Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:
- A basic understanding of the most important spacecraft subsystems and how these interact with each other.
- An understanding of the environment that a spacecraft has to operate in and some basic knowledge of how this environment can affect the spacecraft in terms of operation and reliability.
- An understanding of the basics of orbital mechanics.
- An understanding of what space systems engineering is and what the main types of spacecraft are in terms of their functionality.
