However, an observation of these trajectories almost invariably finds the launch vehicle, at an altitude of a few hundred kilometers, accelerating almost horizontally through the local circular orbit velocity." | |

The Atlas V is "capable of direct insertion into an inter-planetary trajectory." Also the Delta IV supports "direct insertion to GEO." So yes you can and we have the technology, but as others have pointed out the good reasons for not doing it. | |
