Telecommunication systems are provided in rockets and spacecraft to facilitate communication between the space crew and ground control stations.
Ground control stations monitor and guide the motion of satellites and space probes, continuously reporting their positions and decoding signals for useful information.
Spacecraft like Galileo, launched in 1989, have been exploring space for over fifty years, revealing significant findings such as thunderstorms on Jupiter.
Voyager 1 and 2, as well as Pioneers-10 and 11, continue to travel through space at high speeds.
