Satellite telescopes gather a huge amount of data. There are really two kinds of data. "Housekeeping data" is information about the satellite and its health and safety. It tells you where the satellite thinks it is pointing, what its temperature is, which parts are working, and similar status information. This housekeeping data is used by the ground crew to make sure everything is working properly.In addition, the instruments on board also have their data, "Science data". This is the fun stuff -- the images, spectra, count rates, and other measurements of the celestial object you want to study. Most of the data that you transmit to the ground will be this science data. Scientists also use the housekeeping data to evaluate how well the instruments were functioning during the collection of their science data.Data is stored onboard the satellite and sent down to earth in batches, every orbit or every day or as often as possible. Sometimes, data can be sent in realtime -- as the instruments make their observations, they instantly beam the results back to Earth.
A radio or microwave mast
Space probes- instrument that gathers data and sends it back to earth, and an artificial satellite is when people go up to space and gather data and then go back to earth to go over the data
A satellite
neither it is usually referred to as a launch vehicle. a space probe is unmanned and transmits data back to earth and a space satellite is something that orbits the earth. you could call the shuttle a satellite but it is not normally referred to as that.
Manned spacecraft generally require a much higher data collection time than unmanned stations
Satellite systems can be used to transmit audio data
Satellite systems can be used to transmit video data
Electrical or magnetic storms interfere with some of the data-collection methods of a satellite.
Satellite dish is used to receive the data colleted by the satellite and to give commands to it.
A satellite communication simply bounces a radio or data wave to another satellite or a receiver on earth. Satellites all act as giant relays for data transmissions.
The panamsat corporation uses this satellite
It's a satellite that orbits a planet to gather data about it, like weather data or land mapping or upper atmosphere research.
Yes, satellite images based on data obtained by land sat satellites.
Yes, through the use of global positioning systemsscientists use satellite data to predict earthquakes.

Globalstar Network is a satellite constellation for satellite phones and low-speed data communications. It is similar to the Iridium satellite constellation.
Usually by radio.
