With a constant gravitational force ... with zero velocity (it just barely escaped). Here is the conservation of energy equation (again, assuming that the planet doesn't change kinetic energy ...

As the spacecraft exits the planet's gravitational field, it is propelled in a new direction with increased velocity provided by the planet's orbital momentum. Why NASA believes the Jovian moon ...
