New captioned images from HiRISE, http://hirise.lpl.arizona.edu/nea.php.

Pics, wallpaper and scrollover clips. Apparently, the Webmaster has a lot of time on his hands.

Thanks for the very nice crop, ND! smile.gif

Question: Have we seen light streaks anywhere else before? I don't recall them. I am tempted to speculate that dark streaks turn light over time via some chemical mechanism (presumably an interaction with the atmosphere), but again this looks like the first place we've seen light streaks...

EDIT: I just noticed that there are also gray streaks in ND's image! Apparently there is in fact an intermediate phase, whatever direction the process goes. What's going on here? huh.gif

If wind-borne dust accumulation was responsible for changing the streaks' contrast, it would make much more sense if they just vanished into the background. I'm at an utter loss to explain why in this image they apparently become brighter then the surrounding terrain.

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

It may not be from a related process, but THIS is the most famous other light streak on Mars.
