Question

Quizplus · Accepted Answer

In order for a rocket to travel from Earth to another planet, it must first attain escape velocity from Earth. Escape velocity is the speed at which an object must be launched from Earth in order to overcome the gravitational pull and leave the planet's atmosphere. Without attaining escape velocity, the rocket would not be able to break free from Earth's gravitational pull and reach another planet. It is not necessary for the rocket to carry a lot of extra fuel or have very large engines, although these factors can certainly affect the rocket's performance. The rocket can be launched from either the ground or space.
