Gravitational Slingshot | How We Steal Energy from Planets 🚀🪐

[00:00:00]How do we send spacecraft to the furthest reaches of our solar system without carrying enough fuel to get there? We steal it from the planets.

[00:00:06]It's called a gravitational slingshot.

[00:00:09]By flying a probe close to a massive planet like Mars or Jupiter, engineers can use the planet's own orbital momentum to whip the spacecraft forward, adding thousands of miles per hour to its speed.

[00:00:21]This maneuver doesn't just save fuel.

[00:00:24]It's a delicate dance of physics.

[00:00:26]As the spacecraft gains energy, the planet actually loses a microscopic immeasurable fraction of its orbital speed. It is the ultimate cosmic trade, allowing us to reach the outer planets in years instead of decades.

[00:00:39]If you could use a gravity assist to visit any planet in the solar system, which one would you pick as your slingshot?

[00:00:45]Because in the deep void, a little gravity goes a long way.
