"Threads" in microscopic images
What's this all about? Does anyone know what pics specifically they are talking about?
Mr. Squyres was not able to explain the presence of what appear to be puzzling thread-like features seen in Opportunity's microscopic pictures of soil. He suggests that they might be threads from the airbags which cushioned the rover's landing. The airbags, he says, took an awful lot of beating and may have lost fibers in the soil. "I don't know that these things are Martian," he said.
