I don't think it's possible to get sub-atomic resolution like that--at least not by any method I know of or could even imagine...

Anyway, if anybody asks me about the mystery of the missing antimatter, I say what mystery? Then when they say where has all the antimatter gone? I say this:
It hasn't gone anywhere. Weight by weight, you are 99.95% made of it.
A rocket works, for us laymen, by pushing off something. A terrestrial-launched rocket goes nowhere until thrust is given, pushing the rocket off the pad because the expelled air and heat push off the ground. Or the submarine. When launched from a plane, the rocket is dropped from under the wing, and shortly thereafter its thrust begins and the rocket goes forward, this time because it is pushing on air. Were you to take a Saturn-type setup and drop it from, oh, half a mile up, point upwards, somehow, and let it drop, then fire the thrusters, whether or not you make it up, and so escape that gravitational pull, would be a risky proposition. This is just 1/2 a mile, in Earth atmopshere.
I would think that the higher the charge to mass ratio, the more velocity one could impart on the ions.
Assuming Energy is cheap, and matter to expel is expensive (plus the weight of carrying and accelerating the unused propellant), then one would absolutely want to maximize the velocity the ions are being expelled at.
Can one ionize H2 ==> H+ + H−
Easy. Attach the hydrogen to some carbon atoms, burn the whole lot, and plant trees to recycle the resulting CO2 and H2O into more hydrocarbon fuel, using free solar energy.
The a is always there, the v is increasing with t and not constant. Your ballpark is huge.The orbital velocity decreases with time.
Leave it to the physicists to write a program calculating where the moon was every day of its existence.
Suffice it to say that a few cm a year of receding from Earth isn't enough to fling the moon off towards Jupiter, at least not yet.
