From Texas Standard:
Humans create a lot of trash. It's everywhere, from the oceans to the sides of Texas highways to our own backyards. But planet Earth isn't the only place that we've deposited our junk. There's also lots of junk in space, including decommissioned satellites and pieces of rockets. And it's all stuck orbiting around the Earth without much rhyme or reason. That means space junk can collide with and damage working satellites. A UT engineer wants to do something about it.
