Galager

Ok i got the game a week ago and love it but got some questions. First of when your on a planet and want to got to a city how do you get there fast. A starship will get around 350m/s and even a shuttle that moves at 1499m/s it takes hours to get around. Is there something im missing. Also how do i find money i cant seem to find enough to keep my ship alive. Any help?
