A Harvard scientist would confuse meteorites with asteroids??

He said micrometeorites - which is the correct term for small rocks and debris in space. The ISS gets hit with them all the time. It could use some sort of shield. The Chinese return capsule was holed by a micrometeorite, forcing the guys to use the older capsule to return to Earth.
Since when do meteorites come in large swarms? I call BS about all the reporting about a story that only the government is in control of.
