If you want to launch a rocket into outer space, you have to do a lot of math. One calculation of particular importance is something called escape velocity. Escape velocity is the minimum speed needed for an object to overcome the gravitational pull of a celestial body like a planet or moon. If the object fails to reach this speed, it will eventually fall back to the surface, unless further propulsion is applied.
