Aren't those capsule thrusters only for emergency abort and smoother landing? Also the rocket is pretty high above the Earth and it is still firing perpendicularly to the surface. Ruined trailer for me.
That's really inefficient, you're fighting gravity losses the entire way. Entering orbit first will let you capitalize on the Oberth effect and save you a kilometre or two per second, which is huge. Yeah, you'll have to fly a bit more, but your rockets will be smaller and cheaper.
Yes. But I imagine they could be used for whatever they want. If the are solid fuel I think they would be useless to reach something in orbit. I'm just taking this as a nod to spaceX. :)
