How to slingshot your spacecraft infographic

You can use any gravitational source, a planet, a star, or even a blackhole, to DOUBLE your speed, like a slingshot!

This is called "gravity assist" because you use the gravitational field and movement of a planet to add velocity to your own.

The cool part is: it's FREE!
Just make sure to not get too close...

You can also use gravity assist to DECELERATE your spacecraft -for free-.

Instead of traveling "behind" the planet, relative to it's motion in space, you travel in front of the planet. This way the planets gravity diminishes your forward speed.
