Satellite launchers are powerful rockets designed to carry satellites into space. They work by generating thrust through controlled explosions of fuel, propelling the satellite into orbit around the Earth. These launchers can vary in size and capability, depending on the weight and destination of the satellite. Once a satellite is launched, it can serve various purposes, such as communication, weather monitoring, or scientific research. The launch process involves careful planning and coordination, often conducted by organizations like NASA or private companies like SpaceX. Successful launches are crucial for advancing technology and improving global connectivity.
