RADIO AND TV IN OUTER SPACE
Radio waves serve as a most reliable means connecting the spaceship with the Earth. Since the time when the first rocket was sent into space, there is always a two-way communication channel between the Earth and space. The most valuable information is transmitted to the Earth from rockets and spaceships by radio waves.
The information from space comes to the Earth in a coded form and here it is – decoded into the language clear to the specialists. Radio signals which are sent to the Earth from space are much weaker than those which are emitted by radio stations on the Earth. That is why the ground-based receiving antennas should be very big. The greater the antenna area, the more reliable is the reception.
Here on the Earth we not only hear the voices of our cosmonauts out can also see them thanks to the television transmitters which are set up in the spaceship cabin. The cosmonauts use portable TV cameras to send telecasts from their space home and show the televiewers the Earth and the Moon. And so in addition to two-way radio communication there is a two-way television channel from the Earth – to space and back.
Outer space is a gigantic natural laboratory. Here people can observe and study new phenomena, discover laws of nature and then use their knowledge for the benefit of mankind. And here radio and TV are of great help.
