Did you know?
WebJan 6, 2024 · The way a gravitational slingshot is often explained is that a small body (e.g. a space probe) uses the gravitational attraction of a large one (e.g. a planet) to speed itself up. This explanation ... WebA good gravity assist works if you can ensure that your hyperbolic trajectory minimizes the angle θ between the assisting body's trajectory and the spacecraft's exit trajectory. It is …
WebAll objects attract other objects because of a force called gravity. Gravity is a pulling force that works across space. That is, objects do not have to touch each other for the force of gravity to affect them. For example, the … A gravity assist around a planet changes a spacecraft's velocity (relative to the Sun) by entering and leaving the gravitational sphere of influence of a planet. The spacecraft's speed increases as it approaches the planet and decreases as it leaves the planet. To increase speed, the spacecraft approaches the … See more 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 See more A spacecraft traveling from Earth to an inner planet will increase its relative speed because it is falling toward the Sun, and a spacecraft traveling from Earth to an outer planet will decrease its speed because it is leaving the vicinity of the Sun. Although the orbital … See more Luna 3 The gravity assist maneuver was first attempted in 1959 for Luna 3, to photograph the far side of the Moon. The satellite did not gain speed, but its orbit was changed that allowed successful transmission of the … See more In his paper "To those who will be reading in order to build" ("Тем, кто будет читать, чтобы строить"), published in 1938 but dated 1918–1919, Yuri Kondratyuk suggested that a spacecraft traveling between two planets could be accelerated at the beginning and … See more The main practical limit to the use of a gravity assist maneuver is that planets and other large masses are seldom in the right places to enable a … See more The use of gravity assists is constrained by a conserved quantity called the Tisserand parameter (or invariant). This is an approximation to the Jacobi constant of the restricted three-body problem. Considering the case of a comet orbiting the Sun and the … See more • Spaceflight portal • 3753 Cruithne, an asteroid which periodically has gravitational slingshot encounters with Earth • Delta-v budget • Low-energy transfer, a type of gravitational assist where a spacecraft is gravitationally snagged into orbit … See more

The NASA/European Space Agency Ulysses mission used Jupiter's … WebApr 1, 2000 · The force of gravity acting on an object is also that object's weight. When you step on a scale, the scale reads how much gravity is acting on your body. The formula to determine weight is [source: Kurtus]: …
WebGravity assists are orbital maneuvers used to alter a rocket's trajectory and speed using a celestial body's relative motion and gravity with little or no fuel. They are done to save fuel and reduce the budget at the expense of time. They have been used by many rockets throughout history.

The idea behind a gravity assist is to use a planet's motion to accelerate a satellite. For example, a satellite heads toward Jupiter -- in the process, it accelerates because it is "falling toward" Jupiter.
