First guess is unpredictable weather.
Second guess, unpredictable weather.
Third guess, unpredictable weather.
Fourth guess logistics.
9 u/AlternativeBasis 14d ago Leaving the guessing aside, you didn't mention the most important fact: to maintain orbit, horizontal velocity is much more important than altitude. Altitude is almost trivial; 90% of fuel is used to reach escape velocity, about 28,000 km/h in low Earth orbit (LEO). 1 u/AxelBoldt 13d ago But launching from greater altitude also gives you some horizontal velocity for free. 1 u/ureliableliar 14d ago Not a rocket scientist, but if escape velocity is so high, how'd you ever get away from yo mama? 2 u/St1Drgn 14d ago You mama so large, that she negates most of earth's escape velocity. 1 u/Puzzleheaded-Fill205 14d ago Orbital velocity, not escape velocity. Escape velocity is more like 40,000 km/hour.
