Why we send Rockets to space

Since that time, over 2,500 satellites have been launched into space. Would you have ever guessed there are that many satellites up there in the sky, traveling around the Earth over and over again?

What in the world do they do up there? Why do we need so many of them? Artificial satellites are used for all sorts of purposes. Satellites like the Hubble Space Telescope, the International Space Station, and the Russian Mir space station help scientists explore space in new and exciting ways.

Communications satellites help us communicate with people all over the world. Weather satellites help us observe the Earth from space to help predict weather patterns. Radio and television satellites beam our favorite songs, movies, and television shows to Earth for us to enjoy.
