The government is backing a new project to find and keep an eye on small bits of space junk that can be pretty dangerous. Piyush Mehta, who's in charge of the project, explains that it's not about how big these bits are, but how fast they're zooming around. Even something as small as a grain of salt can be like a speeding truck. The project, funded by the U.S. government, will first figure out where these bits are and then come up with ways to track them. They're planning to create a pretend space to test everything out.
