Scientists are still exploring exactly what can be done in outer space and how we can do it, so mostly the space shuttles and space stations have been used for research about weightlessness, vacuum, and other aspects of being in outer space. Space certainly has some very solid practical applications already, such as communications satellites and global positioning satellites, and one of the functions of space shuttles has been to put satellites in their orbits (although there are also other ways of putting satellites into orbit) and in some cases, to repair satellites that are already in orbit.
There are more than 800 active satellites currently in orbit. They represent four percent of the total number of objects currently cataloged by the U.S. space surveillance network; the rest includes abandoned satellites, spent rocket boosters, and other debris. The United States owns more than 400 active satellites, just over 50 percent of all satellites. Russia and China have the second and third highest number of space assets, owning 89 and 35 satellites, respectively. Civilian satellites, which perform tasks for the commercial, scientific, and government sectors, make up the majority of U.S. satellites. Russia's space assets are split nearly evenly between military and civil missions, though there are not separate military and civilian space programs. Only a very small percentage of other countries' satellites are military in nature. www.ucsusa.org/nuclear_weapons_and_global_security/space_weapons/technical_issues/satellites-types-orbits.html
There are 13 countries which have the capability to launch satellites to orbit. Those are: Soviet Union / Russia United States France Japan China UK India Isrel Russia Ukrine Iran North Korea South Korea --note-- The above information is incorrect. The Soviet Union does not exist since 1991. Russia and Ukraine inherited their space facilities from the former Soviet Union. Britain and France launch satellites under the aegis of the European Space Agency, which also launches satellites for many other countries. South Korea does not have an indigenous satellite launch ability at this time. Private corporations SpaceX and Orbital Sciences have been launching satellites for years.
yes. images transmitted from a satellite can be used to spy on things. there are currently satellites in space that can read a newspaper.
Yes, the orbital effects of the earth`s gravity will affect the ISS the same way as it affects other satellites.
Satellites are in space not in countries.
To send up satellites into space to spy on other countries
millions, if you count natural satellites.

space satellites are in space and earth satellites are in earth.
The satellites are sent into outer space by rockets. They revolve around the Earth. Signals are sent up to the satellites which transmit them back to Earth, covering a much larger area in the process. It is because these satellites that you can see events such as cricket matches being played in England or West Indies live on your television. Telephone and computer signals are also sent to other countries through satellites.
are space satellites input or output devices
Applications satellites, like weather satellites, communications satellites (TV, Cell phone, internet), military observation birds, reconnaissance satellites and other "useful" things predominate. Purely scientific satellites such as the Hubble Space Telescope are in the minority.
ther are 4 satellites
