Space flights are easy - try for yourself...
You don't need to be an orbital mechanic to wander around PE31H.
Once in-flight, just point in the direction you'd like to accelerate at and hit the thrusters - your spacecraft will change its' bearing and the new acceleration vector will be added to the current momentum.
To slow down - use the quantum brakes.
Bear in mind that your trajectory is affected not only by your speed and direction but also by the gravity of celestial bodies.
