Micrometeorite impact on WFPC2
Micrometeorite impact on WFPC2 A closeup photo of the exterior housing on Hubble's Wide Field and Planetary Camera 2 (WFPC2), which spent more than five years in space, shows the largest of many micrometeorite impacts that pock its surface. The crater is about the size of the head of a pin, and has a raised rim. Doug Ellison
