The only acceleration applied to the Voyager and Pioneer spacecraft were very small and very infrequent mid-course corrections. Planetary spacecraft use the gravity fields of planets to accelerate relative to the Sun as they flyby enroute to their ultimate destination.

No worries on the name. So you want the angle between the (spaceship to planet) and (spaceship orientation) would the angle between the (spaceship to planet) and (spaceship velocity) be useful as well? I should be able to do both. I may also be able to calculate the required orbital velocity on the...

is there another marc griffith (marcg) out there? Please dont confuse me I may develop an identity crisis. On the subject of thrusters, well ive been mucking about with other stuff and exams are up for me soon: must do my homework, they may take a while yet. Slaved to the joystick is a good idea, b...
