Optimal conditions of the spacecraft acceleration in the gravitational field of planet

In the approximation of Laplace's sphere influence method, there were established the optimal conditions of the spacecraft acceleration in the gravitational field of the planet, which are determined by the value of the spacecraft velocity on the Earth orbit, as well as by the character of Keplerian trajectory in the sphere of the Sun's influence and the impact parameter relative to the planet. As an example, there was calculated the acceleration of the spacecraft in the Jupiter's field for initial velocities from the Earth's orbit in the range (40 divided by 50) km s-1.
