Meaning and Definition
A person specifically trained and designated to manage, operate, and conduct experiments on the scientific or commercial equipment (the payload) carried aboard a spacecraft or launch vehicle.
An astronaut role focused on managing the primary mission-specific cargo, which can include scientific instruments, satellites for deployment, or commercial modules. The term can also be applied analogously in computing/cybersecurity to refer to a component of malicious code designed to execute a specific action, but this is a separate technical usage and not a designation for a person.
