LASCO captures piece of itself
Date: 02 Feb 2005
The streaking in this 19 second exposure is similar to what you would capture if you were to hold a camera lens open for several seconds and take a picture of snow falling. Just as the snowflakes that passed closest to the lens would appear as fat, out of focus streaks, this MLI flake also appears as a thick, bright streak. What caused the MLI to flake off? Probably, a micrometeorite struck the brittle insulation, not an uncommon event for spacecraft. This type of image has sometimes been observed when a cover of one of the instruments has closed with some force and knocked off some of the spacecraft's insulation, but no covers were closing on this occasion.
