Touchdown! Greaser!
So I've had some downtime and got to reading about Apollo 13 and such, and space travel questions arose...
Am I right to think that the power required to propel a mass into earth orbit is probably much, much bigger than the power required to move the same mass from the earth to the moon (even though the distance is much, much greater)?
Just looking at the rocket sizes used to defeat earth's gravity tells part of the story (I realize the mass sent into earth orbit is many times that which is sent from earth to moon).
How much greater? Ie 100 units of thrust puts us into earth orbit vs 1 unit to send a ship earth-moon? (assume the mass in each case is identical.
