The Interplanetary Superhighway

Remember when mom asked, "What do you want to be when you grow up?"

Now you can be sure. "I want to be a celestial mechanic."

In celestial mechanics, the gravity of the orbs in the sky competes with all the other gravitational attractions. As the Sun pulls on Earth, Earth pulls on the Sun. Earth and Pluto have some attraction. Minute, but there. Mapping the harmony of the worlds renders spatial passages that require lower energy than usual to travel in- from world to world.

NASA's Jet Propulsion Laboratory image of the superhighway shows the lowest energy path from the Jupiter to Saturn systems.
