Key to the equation is the fact that the force ... fuel and throwing the exhaust out the back of the rocket. You generate ten times as much thrust when you throw 10kg of exhaust out the back ...

has the highest thrust-to-weight ratio of any rocket engine ever made. Significantly, the Merlin engines—like roughly 80 percent of the components for Falcon and Dragon, including even the ...

Tsiolkovsky devised a complex equation that revealed the necessary thrust force needed for any given rocket maneuver, and the "specific impulse" — how much thrust is generated per unit of fuel ...

In order to keep that top mass stationary (for the whole rocket pendulum thing) the thrust force must also change both in magnitude and in direction of the thrust. So, this is not a normal rocket ...

After the rocket has been hammered up through a big chunk of the atmosphere and given a good start, the high-thrust stage is ... not the practical side of the equation can balance the romantic.
