Explore the complex process of designing and building a satellite using the MAVEN mission to Mars as an example. Plans for the MAVEN satellite went through a thorough review of the concept, budget, and risk analysis before proceeding to the next step of the process. Even after the design review is approved, there are many steps to complete before the satellite can be built. Installing something as simple as a bolt involves many steps, including testing, approval, cleaning, and retesting. In addition, spacecraft contain complex electronics, which require an exceptional amount of work to develop and install.
