Subject : Fwd: Mars Opportunity images - Question
Mr. Arvo,
Your message below was forwarded to me for response.
The anomaly you spotted appears to be a speck of dust that was temporarily located on or just in front of the left Navcam. It is not present in the right Navcam frame collected at about the same time, and is not present in images taken by either the left or right Navcam a couple of minutes before and after. Mars is a pretty dusty and windy place. I would imagine that the wind blew a speck of dust onto the lens and then subsequently blew it off. We see the same thing happening to the solar array: it gets dusty and produces less power, but a dust devil sweeps by every now and then and blows the dust off, allowing the rover to get more power.
Thank you for your interest in the mission!
Curt Niebur

I agree with you the way you view the issue. I remember Jack London once said everything positive has a negative side; everything negative has positive side. It is also interesting to see different viewpoints & learn useful things in the discussion.
