you know, science.

But it's the equivalent of hitting a golf ball in New York City and getting a hole-in-one in L.A.

That's the scale of landing something on Mars.

Yeah.

And it's a real problem.

Like the concept of space junk of like, if to your point, if two satellites crash into each other in space and they each create, you know, 5,000 pieces of debris.

Now you have to track all 5,000 of those.

And you could have a runaway problem where just stuff just starts crashing.

Like when the moon exploded.

Yeah, exactly.

But with our own satellites.

So that's why we track everything over the size.

I think it is a golf ball.

we know where it is at all times orbiting our planet.

Because there's no vacuum cleaner to just go up and... No, not yet.

But there are missions of like, how do we clean up space junk?

They're actively working on ways to go up and like clean defunct satellites.

And now if you put something up, I just built a satellite, which is wild you could do that, where we put it into space, you can upload your picture to it, and there's a screen that will display a picture, and then there's a camera that will take a picture of that.

So basically you get a selfie in space.
