SpaceShipOne and the other things they have planned are a good parabolic roller coaster, but they can't achieve orbital velocity.

SpaceX on the other hand, is our only hope.

OUR ONLY HOPE.

So space injectors must reach speeds around 7-8 kilometres per second in order to put the satellites into low orbits.

If you think about it its pretty fucking fast, however it doesnt 'take off' at 8km/s.

Where exactly does it reach the final speed?

Orbital mechanics are covered enough by Newton/Kepler laws right?

I mean that's all you need to put stuff into low circular orbits, right?

I heard they dont even care about the perturbations caused by the moon when launching a low orbit satellite.
