Outer space is a great realm of possibility and the question is whether or not that realm of possibility will be closed off.

We track 25,000 plus objects continuously to understand where they are and if they pose a hazard to each other.

There's a real danger that there's going to be militarization of outer space.

They've got to be able to go in and say,

look, I've got everything in my arsenal

to just wipe you out, but I don't want to do that.

I don't want to make this domain unusable for everybody.

Space is an infinite horizon, an endless void full of possibility.

But the part of space near Earth is getting really crowded,

and it's getting really dangerous.

It used to be just Russia and the United States.

But now nine countries and dozens of private entities are regularly launching objects into space.

All of these players are competing for limited real estate.

Crowding leads to conflict.

And so far the world hasn't developed rules to solve space disputes or to prevent war

from spilling over into the night sky. As things heat up some countries are pouring

billions of dollars into space defense.

The technologies are futuristic sounding.

Anti-satellite lasers, high-altitude EMP weapons.

But the biggest danger is something slightly less glamorous.

Space Junk.

I'm Gabriel Sierra and this is why it matters.
