On another thread, in response to my question, someone suggested that the ragged edges might be pixillation since they appear on all of the edges of the shuttle, not just the the left wing. That doesn't explain the apparent plume off the trailing edge of the left wing, but there is also a smaller plume off the trailing edge of the right wing. Professional photo analysts can hopefully give a more definitive answer.

Perhaps the plume coming off of the trailing edge of the right wing is evidence of heat and or smoke. An infrared exposure would be helpful.
