Jupiter Slingshot. Instructions: (after you've read these, click here to get a bigger picture.) Click and drag the arrow to change the direction of launch of the spaceship. Choose Jupiter's path distance (the shortest distance of the initial launch point from Jupiter's orbital path) and initial speed of the spaceship. RESET: puts Jupiter into ready position at far left START: Jupiter begins moving at its orbital speed SHOOT: launches the spaceship Zoom in or out to see the full orbit of the spaceship! You can also right-click on the movie and zoom in to get a better view of the objects. Note: Jupiter moves through a distance equal to its diameter in about 3 hours. *** This flashlet demonstrates in a semiquantitative way how a properly directed spaceship can pick up energy from a moving planet.
