Questions and Answers

What is the purpose of functional testing in system integration and test?

To characterize the payload or system
To check if subsystems work together (correct)
To demonstrate the final system integration
To perform environmental testing

Why might combined functional and environmental testing include spacecraft level thermal vacuum?

To ensure the safety of ground systems like propulsion and attitude control
To characterize the payload or system
