What is gravity assisst?
That refers to using the gravity of a planet - for example Jupiter - to speed up a spacecraft. Note that the spacecraft approaches the planet with a certain speed, and goes away from it at the same speed, with respect to the planet. However, since in doing so it changes direction, and since the planet orbits the Sun, it is possible to set things up so that the spacecraft leaves with a greater speed with respect to the Sun.

How does the slingshot effect or gravity work to assist a change in orbit of a spacecraft?
Gravity AssistIt's called Gravity Assist. Overcoming gravity is all about velocity. Escaping Earth's gravity requires approximately 25,000 mph. Escaping the Solar System needs more than 45,000mph. We dont have a large enough rocket to achieve that speed so spacecraft can use a planets gravity to increase its velocity and then the planet can "slingshot" it onto a new trjectory toward the next target. The gravity of a large object can "pull" something to a higher velocity and then, rather than crash into the object, the craft can just miss the planet or moon and, for a moment, go into orbit. The centripital force of the orbit will increase the craft's velocity and "shoot" it off on a new trajectory. ------------Nope, that's wrong. An orbit is (by definition) symmetrical. There is no change of energy in an orbit (that is, no change to the sum of kinetic energy and potential energy). Any kinetic energy gained by a spacecraft on approach to a planet, by trading gravitational potential, must be lost on leaving it, as the kinetic energy is converted back into potential.You can only make sense of a gravity assist by also considering the planet's orbit around the sun. By arranging a suitable slingshot configuration you can steal the orbital energy of the planet around the sun and give it to the spacecraft. The planet ends up in a lower (less energetic) orbit, while the spacecraft ends up in a higher orbit relative to the sun. It has nothing to do with the centripetal force of the spacecraft's orbit or hyperbolic trajectory around the *planet*.
Which planet did the spacecraft Magellan enable scientists to research extensively?
Venus was the planet that the spacecraft Magellan enabled scientists to research extensively.
Does gravity always pull a spacecraft towards the nearest planet?
Not necessarily. While it is true that gravity is an inverse square relationship with distance, making closeness an important factor, mass is also important, so, for example, if two planets were in the vicinity of a spacecraft, gravity would depend on both mass and distance. Yes, distance is a squared factor, but if one planet were very much larger than the other, it could easily win out, even if it were further away.
What will happen to the pull of the planet's gravity if a spacecraft nears Mars?
The presence or absence of spacecraft near Mars will have no effect whatsoever on the planet's gravitational field.
Why does the force that pulls you towards the center of a planet or star?
Gravity.
How do gravity and inertia determine the orbit of a planet?
the sun's gravity pulls the planets towards it but the other planet's gravity helps keep the planet not get sucked towards the sun. With gravity working this creates the planet to orbit the sun
When using a planets gravity for acceleration the gravitational energy is transferred to kinetic energy so where exactly is this energy reduced from in the planet used for this maneuver?
Gravity is not a form of energy. When a spacecraft manuevers near a planet in a certain trajectory, relative to the motion of the planet, the spacecraft will be accelerated at the expense of the planet; the planet slows down ever so slightly.

How spacecraft go from one planet to another?
We use science, technology and some help from gravity.

What will happen to a spacecraftas it gets very close to a planet?
the spacecraft will be pulled in towards the center or core of the planet....although it has the possibility to be magnetized, the spacecraft won't be magnetized if it didn't enter the territory of the planet..... because a planet was considered to be a "giant ball of magnet"..

How does gravity affet the movement of planets?
Mainly, the Sun's gravity attracts a planet; as a result, the planet accelerates towards the Sun (the direction changes gradually, so the planet goes more in direction towards the Sun), resulting in the curved orbit.
How are slingshot mechanisms used to accelerate interplanetary spacecraft?
Good question. Imagine a spacecraft is approaching a planet. The planet is moving around the sun. The spacecraft path is adjusted to approach the trailing limb of the planet -- the rear edge of the planet when you look at its orbit around the sun, not its dark side. The planet pulls on the spacecraft as it goes by (and actually the spacecraft pulls on the planet, too). If the spacecraft were close enough to the planet, and traveling slowly enough, it would be captured by the planet. But it is possible to put the space craft in a path so that will not be captured--it can be pulled by the planet so that the spacecraft gains velocity. The planet loses velocity, but since planets are huge and spacecraft small, the planet's velocity is barely affected. It is hard to visualize this, but imagine a ping pong ball being struck by a soccerball in mid-air (this would make a good science class demonstration)--the ping pong ball will pick up tremendous speed by being struck by a heavier ball. The heavy ball will hardly notice it. You can do this by dropping the soccer ball with the ping pong ball on top of it. Slingshotting a spacecraft (also called gravity assist) works in a similar way except the spacecraft would be pulled by the planet's gravity instead of being pushed (as with the two-ball demonstration).
