Browsing a comparison of orbital launch systems on wikipedia, I notice that launcher capable of launching payload in GTO can launch in GTO approximately all the mass of the payload they can launch in LEO (seems reasonable), and that launcher capable of launching heavier payload in LEO are able the one able to launch heavier payload in GTO (seems logical). 2 lines stroke me:
Ariane V ECA:
- LEO payload: 21000kg
- GTO payload: 10865kg
Falcon 9 Full Thrust (expended):
- LEO: 22800kg (more than Ariane V)
- GTO: 8300kg (less than Ariane V)
If a launcher is more powerful, it should launch heavier payload both in LEO and in GTO. Why this is not the case for this 2 launchers?
