Gravity assist
In orbital mechanics and aerospace engineering , a gravitational slingshot , gravity assist maneuver , or swing-by is the use of the relative movement (e.g. orbit around the Sun ) and gravity of a planet or other astronomical object to alter the path and speed of a spacecraft , typically to save propellant and reduce expense. Gravity assistance can be used to accelerate a spacecraft, that is, to increase or decrease its speed or redirect its path. The "assist" is provided by the motion of the gravitating body as it pulls on the spacecraft. [1] The gravity assist maneuver was first used in 1959 when the Soviet probe Luna 3 photographed the far side of Earth's Moon and it was used by interplanetary probes from Mariner 10 onwards, including the two Voyager probes' notable flybys of Jupiter and Saturn.

In orbital mechanics and aerospace engineering , a gravitational slingshot , gravity assist or swing-by is the use of the relative movement and gravity of a planet or other celestial body to alter the path and speed of a spacecraft , typically in order to save fuel, time, and expense. Gravity assist can be used to decelerate or accelerate a spacecraft. The "assist" is provided by the motion (orbital angular momentum) of the planet as it pulls on the spacecraft. The situation is similar to throwing a rope around the neck of a galloping horse, being dragged along by it, and then cutting the rope while moving forward. The horse, in this rough analogy, is quite large and heavy. [1] |

In orbital mechanics and aerospace engineering , a gravitational slingshot or gravity assist is the use of the gravity of a planet or other celestial body to alter the path and speed of a spacecraft . Passing by such a body imparts some fraction of that body's speed to the spacecraft. It is a commonly used maneuver for visiting the outer planets , which would otherwise either take far too long or require far too much fuel using our current propulsion technologies. It was first developed in 1959 at the Department of Applied Mathematics of Steklov Institute . [1] |
