Cathode Ray Tube (CRT)
A Cathode Ray Tube (CRT) is a vacuum tube that uses an electron gun to produce images on a phosphorescent screen. In the context of space and astronautical engineering, CRTs were commonly used in older spacecraft and satellites as display screens for telemetry data and other information. They were also used in older ground-based tracking systems for spacecraft. However, with the advent of newer technologies such as LCD and LED displays, CRTs have become obsolete in modern space systems.
