Answer: What is Payload Deployment and Retrieval System mean?

Flight controllers are personnel who aid space flight by working in such Mission Control Centers as NASA's Mission Control Center or ESA's European Space Operations Centre. Flight controllers work at computer consoles and use telemetry to monitor various technical aspects of a space mission in real time. Each controller is an expert in a specific area and constantly communicates with additional experts in the "back room". The flight director, who leads the flight controllers, monitors the activities of a team of flight controllers, and has overall responsibility for success and safety.

This article primarily discusses NASA's flight controllers at the Johnson Space Center (JSC) in Houston. The various national and commercial flight control facilities have their own teams, which may be described on their own pages.
