Through years of research and development the military discovered the use of the radar bands (a group of waves within the electromagnetic wavelengths designated as radio) of radio for detecting objects. They also use radio waves for telemetric navigation (triangulating position by transmitting to three points and calculating the distance). Since the 60s it has enabled outer space missions to be undertaken, allowing for ground units to assist in the delicate maneuvers of space travel and play the role of ground based environmental information service. Pilots of separate space vehicles also can use radio to simultaneously communicate and calculate their distance from each other by the delay time in transmissions. NASA uses them to receive information from space probes, and to talk to shuttle crews. Overall, radio is a marvelous invention and there are many inventive uses for it.
