Could an ~12ft rocket launch some sort of probe into space

mfb

In terms of required fuel... well, yes, the "fuel per distance" ratio decreases with velocity, and the initial velocity is 0 for conventional rocket launches (=all rocket launches up to now). But this does not mean that lifting the rocket by 2 inches would help in any way. Accelerating it to something like 500m/s or more would indeed help.

I've heard it stated that the most expensive part of a launch is the first 2 inches!

I think what that means is getting it 2 inches off the ground without it malfunctioning and exploding is the most expensive part of the launch.

Couldn't get anything by googling the first time around. It also seems logical that the cost of fuel and safety would be very high for the initial part of the launch. What I wanted was data resembling breakup of amount of fuel required as the rocket gets higher or something like that.
