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
No, TV stations do not broadcast their programs directly from space. Satellite communication technology is used to transmit signals from Earth to satellites in space, which then retransmit the signals to users on the ground.
Television coverage of the landings were broadcast live, so between 1969 and 1972 depending on the mission.
no
They did broadcast audio, but they were unable to broadcast television because, while moving the T.V. camera into position, LMP Alan Bean accidentally pointed the camera lens directly at the unfiltered sun, burning out the vidicon tubes inside the instrument.
There is different types of artificial satellites, each for different uses. For example : Weather satellites help meteorologists predict the weather or see what's happening at the moment. Typical weather satellites include the TIROS, COSMOS and GOES satellites. The satellites generally contain cameras that can return photos of Earth's weather, either from fixed geostationary positions or from polar orbits. Communications satellites allow telephone and data conversations to be relayed through the satellite. Typical communications satellitesinclude Telstar and Intelsat. The most important feature of a communications satellite is the transponder - a radio thatreceives a conversation at one frequency and then amplifies it and retransmits it back to Earth on anotherfrequency. A satellite normally contains hundreds or thousands of transponders. Communications satellites are usually geosynchronous. Broadcast satellites broadcast television signals from one point to another. • Scientific satellites perform a variety ofscientific missions. The Hubble Space Telescope is themost famous scientific satellite, but there are many others looking at everything from sun spots to gammarays. ( See the article of the telescopes) -> Hiten scientific satellite • Navigational satellites help ships and planes navigate. The most famous are the GPS NAVSTAR satellites, r escue satellites respond to radio distress signals. -> NAVSTAR satellite • Earth observation satellites observe the planet for changes in everything from temperature toforestation to ice-sheet coverage. -> ENVISAT • Military satellites are up there, but much of the actual application information remains secret. Intelligence-gathering possibilities using high-tech electronic and sophisticated photographic-equipment reconnaissance are endless. Applications may include relaying encrypted communication, nuclear monitoring, observing enemy movements, early warning of missile launches, eavesdropping on terrestrial radio links, radar imaging, photography (using what are essentially large telescopes (see the article on the telescopes ) that take pictures of militarily interesting areas)

An object that orbits the earth. for example the moon or the ISS or the telecommunication satellites that broadcast TV
Satellites have a variety of different jobs some broadcast television while others are used in GPS systems.
because on the em spectrum, radio waves are the lowest. if a tv used a higher raadioactive source like uv and you were exposed to it to much (by watching to much tv) you could get cancer and die unfortunately.
Terrestrial is earthbound. It is broadcast from antenna towers here on Earth. Satellite TV is broadcast by communications satellites from outer space in geosynchronous orbit. They orbit at the same rate that the Earth rotates, therefore they remain "parked" over the same geographic region, relative to the surface of the Earth they are standing still. Terrestrial TV also makes use of satellites, but rather than broadcasting directly to a customers dish, they are broadcasting specifically for re-broadcast by local network affiliates over their terrestrial antennas.
Electromagnetic waves in the assigned frequency range of each channel are used to carry information to the TV receiver, which the receiver can use to reconstruct copies of the sound and picture that go together to make up the program being broadcast on that channel.
broadcasting is the process of sending information (ex:video signals or tv programs) to distant places is called broadcasting but where as telecasting refers to broadcast (ex:tv programs) the programs on television i.e. the broadcasted information.
A circuit television is also known as a CCTV or a surveillance camera. A CCTV is a video camera, which only send signals to particular vicinity, on a limited batch of monitors. Whereas a broadcast television, can transmit and admit radio waves, which does not require any satellites to receive signals.
Direct Broadcast Satellites or DBS was the first to have established regulations by year 1980. However, satellite-delivered signals have transformed the television industry since the late 1970s.
No, TV stations do not broadcast their programs directly from space. Satellite communication technology is used to transmit signals from Earth to satellites in space, which then retransmit the signals to users on the ground.
A TV broadcast can be sent to the entire U.S. using a combination of terrestrial broadcasting and satellite transmission. Television signals are typically transmitted from broadcast towers across the country, which cover specific geographic areas. For nationwide reach, networks often use satellites to relay their signals, allowing cable and satellite providers to distribute the broadcast to millions of households simultaneously. Additionally, streaming services and the internet can further enhance accessibility across various devices.
The broadcast center is the central hub of the system. At the broadcast center or the Playout & Uplink location, the television provider receives signals from various programming sources, compresses these signals using digital compression (scrambling if necessary), and beams a broadcast signal to the proper satellite. The satellite receives the signal from the broadcast station and rebroadcast them to the ground. The viewer's dish picks up the signal from the satellite (or multiple satellites in the same part of the sky) and passes it on to the receiver in the viewer's house. The receiver processes the signal and passes it on to a standard television. This was found in the year 1974.
