07. How much force does it take for a rocket to lift off and get us out of the atmosphere? (A K2S Question)
From The Space Library
We need about twice the weight of what's lifting off, which is mostly fuel. The orbiter is only one-sixteenth of the weight on the pad. What is important is the length of time the force is required.
