> Not least, but certainly the requirement to brake before you land must be on the small order compared to achieving escape velocity from the much bigger rock I'm on?
The problem is all the fuel you use to break before landing also has to achieve earth escape velocity at first. And it makes the original problem much harder because the total mass that needs acceleration grow exponentially with delta speed.
