i should imagine its because EM waves can travel through a vacuum so that's why it is possible for satellites to broadcast information from impulse signals sent from outer space
Satellites send information. They can also take pictures of different items. Also, Satellites can help stranded boaters as well. They can also relay signals, which is what makes satellite T.V. possible.
Pictures are sent to earth from outer space through the Hubble Telescope and cameras on satellites. The satellites then send the images to NASA computers.
The canadarm is made for fixing stuff, like satellites or send them into their proper orbit . It is also used for building other spaces structures in space and to reach out to from the spacecraft to send out and bring back payloads, such as satellites.
the first people/ nation to send some form of satellite into space is the russians with thesputnik 1

Broadcasting stations use television satellites to send their signals around the world.

Satellites have different aerials and orbits in order to ensure they do not collide or send mixed signals. Satellites are a vital part to the advancement of technology in the world.

Satellites used for Global positioning, send clock signals back to the earth, along with identity signals. The timing of the clock signals are very accurately controlled. The receiver uses the clock signals and by applying mathematical processes and comparing with an on board almanac, calculates the receiver's position. At least three signals from different satellites are required to fix a position. More signals then add to the accuracy.
Only light is used to send signals along optical fibres. That's why this type of fibre is described as "optical". Fibres designed to conduct electrical signals are referred to as "wires".
