Gravity assist - Wikipedia
WEBA gravity assist, gravity assist maneuver, swing-by, or generally a gravitational slingshot in orbital mechanics, is a type of spaceflight flyby which makes 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 ...
Basics of Spaceflight: A Gravity Assist Primer - NASA Science
WEBThe "gravity assist" flyby technique can add or subtract momentum to increase or decrease the energy of a spacecraft's orbit. Generally it has been used in solar orbit, to increase a spacecraft's velocity and propel it outward in the solar system, much farther away from the Sun than its launch vehicle would have been capable of doing.
Gravity assist - The Planetary Society
WEBSep 27, 2013 · Interplanetary spacecraft often use a maneuver called a gravity assist in order to reach their targets. Voyager 2 famously used gravity assists to visit Jupiter, Saturn, Uranus and Neptune in the late 1970s and 1980s.
Gravity Assists - NASA Science
WEBThe key to the gravity assist technique is that it involves three bodies – the spacecraft, the solar system body that is providing the “assist”, e.g., Venus, Earth, Titan, and the central body about which the spacecraft’s path is being controlled.
How Does a Martian -Style Gravity Assist Actually Work?
WEBJan 3, 2019 · The first question is easy—a gravity assist (also called a gravity slingshot) is a space maneuver in which a spacecraft gets a speed boost by moving past a planet.
How “Slingshotting” Works for Space Flight: A Gravity Assist …

Gravity Assist Maneuver - Definition & Detailed Explanation
WEBMar 22, 2024 · A Gravity Assist Maneuver, also known as a gravitational slingshot or swing-by, is a spaceflight maneuver that utilizes the gravitational pull of a planet or other celestial body to alter the trajectory and speed of a spacecraft.
How Do Gravity Assists Work? - timeanddate.com
WEBIn a gravity assist maneuver, a spacecraft uses a planet’s gravity and movement around the Sun to help it speed up or slow down. How does this work? Let’s take specific examples from the Voyager 1 and BepiColombo missions.
58.5: Gravity Assist Maneuvers - Physics LibreTexts
WEBTo send a spacecraft to another planet, one may often get a "free" boost in velocity by flying by another planet along the way, thus shortening the trip. These free velocity increases are called gravity assist maneuvers..
