Dust devil confirmed; NASA people did see it
It turns out NASA scientists did see the dust devil images even before the eagle-eyed online people noticed it. Science team member Geoff Landis says they were on it right away, even before the images got out to the public via the Exploratorium website.
Still, I think amateur space enthusiast Lloyd Jacobs of Toronto deserves credit, as being apparently the first person to make the discovery public, having spotted it almost immediately last Thursday evening and posted his findings on an online forum less than 4 hours after the images went online.
My story on it is HERE on New Scientist today.
