Could a spacecraft slingshot around a black hole?

Assuming simplest Swarzschild’s black hole: If your spaceship can achieve enormous speeds then theoritically you can slingshot just like jupiter’s case but there will be additional consequences of gravitational plus relativistic time dilations. A black hole can be used to slingshot around just like any massive object.

What does it mean to slingshot a space probe around a planet?

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 …

How do gravitational 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 much speed did Voyager gain from the gravity assist from Jupiter?

During the Jupiter encounter, Voyager 2 gained enough speed to enable it to leave the solar system – the blue curve stays above the red curve beyond Jupiter. It gained about 10 km/s at Jupiter, about 5 km/s at Saturn, about 2 km/s at Uranus, and lost about 2 km/s at Neptune.

Does gravity assist slow down the planet?

Depending on the relative direction of motion of the planet and the spacecraft, a gravity assist can either speed up, slow down, or merely change the direction of the spacecraft.

How do gravitational slingshots use this relationship to accelerate probes to much higher speeds than can be attained purely with rockets?

The closer it can fly, the more momentum it receives, and the faster it flies away from the encounter. To kick the velocity even higher, the spacecraft can fire its rockets during the closest approach, and the high speed encounter will multiply the effect of the rockets. This speed boost comes with a cost.

How long does it take to slingshot around the moon?

Three hours after the explosion, the crew used the Lunar Module’s descent engine to modify their course to a “free-return trajectory” around the Moon, meaning lunar gravity would slingshot them back to Earth….Apollo 13 Timeline.

How long does it take to get to Mars?

The spacecraft departs Earth at a speed of about 24,600 mph (about 39,600 kph). The trip to Mars will take about seven months and about 300 million miles (480 million kilometers).

How does a slingshot probe 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 do gravitational slingshots work?

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 is wrong (or at least incomplete), and the flaw is easy to see. Gravitational potentials are symmetric.

What happens to the speed of a probe when it flies away?

Gravitational potentials are symmetric. So any kinetic energy gained by the probe as it falls down the gravitational well of the large body will simply be lost again as the probe leaves the body. This explanation implies that there will be no net effect on the speed of the probe when it flies away from the planet.

What is the velocity of a spaceship after a slingshot?

Translating this analogy into space: in the planet reference frame, the spaceship has a vertical velocity of v relative to the planet. After the slingshot occurs the spaceship is leaving on a course 90 degrees to that which it arrived on. It will still have a velocity of v, but in the horizontal direction.
