LEILA FADEL, HOST:
Good morning. I'm Leila Fadel. The moon is expecting a delivery soon - three tons of space trash that will crash into its surface at around 6,000 miles an hour. The debris has been floating in space for the past decade, and experts believe it came from a Chinese rocket test. The impact is expected to leave a crater anywhere from about 30- to 60-feet wide, sending moon dust in all directions. An impact of that size is pretty big. I'd even go as far as to say it's astronomical. It's MORNING EDITION. Transcript provided by NPR, Copyright NPR.
