EDIT: Moved these posts from the Feb 14 HiRISE Release thread to here to collect all Beagle 2 search related stuff in one place.
I'm downloading them now too -- guess I can't blog about them until I've examined them very carefully! For a bit of history on the search, Here's a blog entry I wrote about this spot a while ago Here's the MOC team's take on that spot And here's the BBC page with the Beagle 2 team's take on it EDIT: and here's my updated blog entry with links to the Beagle 2 landing ellipse images split up into 40-MB chunks. --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Remember - a cosmic ray hit might be a single pixel in the collected data - but it will 'grow' over multiple pixels during map projection.
Also... http://hiroc.lpl.arizona.edu/images/2007/d..._1920_cut_b.jpg There's nothing about the Ustrax target that elimiantes it from being an imaging artifact. Attached - applying perspective distortion in photoshop on a single white pixel - first just in one direction, then in two directions. See how the dot 'grows'. I don't know how the map projection for HiRISE works - but I imagine it would introduce similar artifacts. Doug |

The point about map projection certainly holds. My opinion is still that it's a real feature, not an artifact.
