What does the slingshot effect do for space probes?

The effect known as the gravity assist or slingshot effect is a way of using the motion of a planet to accelerate a space probe on its journey towards the outer planets. Think of a space probe on a journey to Neptune. On its way it will have to pass Jupiter – the largest planet in the Solar System.

How does gravity assist help a spacecraft reach its destination?

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.

What space probes use gravity assist?

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. Cassini used two assists at Venus and one each at Earth and Jupiter in order to reach Saturn.

How does a black hole bend light if light has no mass?

A black hole is a region of space where gravity is so strong that nothing can escape, not even light. It might be surprising to you to hear that gravity can affect light even though light has no mass. The gravitational curvature of light’s path is a weak enough effect that we don’t notice it much on earth.

How does space slingshot work?

So how does the gravitational slingshot effect work? What the slingshot does is use gravitational attraction to grab some of the momentum of the planet and transfer it to itself. That is, it slows down the planet ever so slightly (like, really, really slightly — because the probe is so much less massive).

How does orbiting Earth affect astronauts?

(B) An astronaut orbiting the Earth does feel weightless because there is no ground or normal force to counteract the force of gravity. Thus, the astronaut is falling. However, since the astronaut is also moving forward super fast, he/she continuously falls around the Earth rather than crashing into the Earth.
