A Hole On ISS

Asttonauts have discovered a small hole in one of the solar panels that power ISS.  NASA thinks the hole was made by a micrometeoroid.

It's unclear when the hole was made since it caused no damage, but the discovery is a reminder of the space junk problem.  If this hole was made by a naturally occurring bit of rock, it could have easily been caused by a bit of manmade debris-- and that debris could have hit a more vital area of the space station.  ISS has the ability to dodge larger bits, but the long term solution is to cut the amount of debris in orbit.
