So this happened today:

Here's a bit more explanation with animations showing how the drone (called Ingenuity) took off from the rover (Perseverance) that landed on the Red Planet in February:

Not only was this an impressive feat because it was the first such powered, controlled flight on another planet, it was also technically challenging since Mars' atmosphere is only 1% as dense as Earth's.

That means drones have to spin their rotors five times faster in order to achieve lift.

The drone will be attempting several longer, more daring flights in the near future, all with the goal of providing insight into using future drones on the planet.

I'm sure that data will come in handy when Imperator-of-Mars Elon Musk visits the planet to claim what is rightfully his.

Pretty dang cool if you ask me.
