dodge this....

Apparently NASA is researching the effects of high-speed collisions of tiny meteorites on the moon's surface. The concept is pretty disturbing, since some of the rocks are travelling at up to 35 kilometres per second when they hit the ground. At those speeds, a spacesuit isn't going to stop you from being turned into a smear instantly... so how are we going to survive in space?
As NASA explains it, you might dodge a bullet but still get caught by its shrapnel. Among the questions they want to answer: Are you more likely to get cut off at the ankles by debris spattered along the horizon, or hit from above by material on high, ballistic trajectories?
