Default Meteor Showering aboard ISS

At NASA, get your comet debris while it's hot:

For 579890main_iss028e024847_full.jpg, the caption reads:

"(13 Aug. 2011) --- Astronaut Ron Garan, Expedition 28 flight engineer,
tweeted this image from the International Space Station on Aug. 14 with
the following caption: "What a 'Shooting Star' looks like from space,
taken yesterday during Perseid Meteor Shower." The image was photographed
from the orbiting complex on Aug. 13 when it was over an area of China
approximately 400 kilometers to the northwest of Beijing. The rare photo
opportunity came as no surprise since the Perseid Meteor Shower occurs
every year in August. The meteors are particles that originate from the
comet Swift-Tuttle along its orbital path; the comet's orbit is close
enough for these particles to be swept up by the Earth's gravitational
field each year. Green and dim yellow airglow appears as thin layers
visible above the limb of the Earth, extending from image left to upper
image right. Atoms and molecules above 50 kilometers in the atmosphere
are excited by sunlight during the day, and then release this energy at
night producing primarily green light observable from orbit. The sun is
low on the horizon as it appears near part of one of the station's solar
panel arrays at image upper right."

Kind of makes you wonder if, one of these days one of these might be a
little on the large side and hit the iss.
