U.S. officials are turning their attention to a pressing problem in space. Not asteroids crashing into earth, but something else: space debris.

Thousands of satellites have been launched into space because our modern life depends on them. There are about 10,000 active satellites in low earth orbit right now. But as more and more of them go up, space is getting crowded.

And where there's crowds, there's waste. Millions of pieces of space debris are circling Earth right now. There are big pieces — everything from dead satellites to spent rocket stages. And tiny ones like blots and paint flecks. But they're all whizzing around at speeds that can be faster than a speeding bullet.

We team up with our friends at the Click Here podcast to take a look at the problem of space debris. We discuss what could happen if an adversary hacks an old satellite and uses it as a weapon.
