In space how do we communicate, when their is no internet and cables
The Basics. At its simplest, space communications relies on two things: a transmitter and a receiver. A transmitter encodes a message onto electromagnetic waves through modulation, which changes properties of the wave to represent the data. These waves flow through space toward the receiver
How did people communicate in space
Messages travel through space as radio waves, just like the radio waves that you receive with a car radio. Each spacecraft has a transmitter and a receiver for radio waves as well as a way of interpreting the information received and acting on it.
Can people in space communicate with people of earth
They also communicate with people on Earth using the Tracking and Data Relay Satellite system, which consists of a series of seven satellites. Finally, they communicate with amateur radio operators on Earth using the HAM radio onboard the ISS
