Thanks for agreeing that all rocket launches are one way trips.
I'm pretty sure that I never said that, but thanks for avoiding my question again.
You send something away with the fuel available. And that's it.
So how does Arianespace make sure that they have enough fuel available to transfer satellites from low earth orbit to geostationary orbit?
Sending any mass (m=kg) away from Earth is simple! Just apply a force (f=N) to it and the mass (m=kg) accelerates away (a=m/s˛) because f=m a. I doubt you understand it, but it is not your fault. You are just stupid. Anyway ...
With too little force f (N) the mass (kg) drops back on Earth due to gravity, but with plenty force f (N), the mass will leave Earth and disappear for ever somewhere in the Universe/God/Allah/Muhamed/GWB/CIA/FBI/NSA/Obama/Donald!
With a force f (N) in between you enter Earth
orbit like the Communist Sputnik. Ever heard about it? Sputnik! I doubt it. It was communist mass that orbited Earth. Nobody ever saw it. Why?
It was just propaganda.
In reality it never happened.
Only peoply suffering from cognitive dissonance like you believe it.
Where you born when the Sputnik was orbitting?
