The kinetic energy required to launch an object into space is proportional to the resistance offered by the air. If the object is directly launched from the ground, it has to travel more distance through air resistance. So, it requires more kinetic energy to overcome this opposing force. It is expensive.

On the other hand, if the object is launched from a higher altitude, need to tr...
