[QUOTE=DavidU;479067]Steve, thats a lot of homework !Looks spot on from here.
When does LRO start imaging from terminal low orbit?[/QUOTE

Thanks David and Al.

David, I cannot find any information at present as to when the hi-res images will start. I would suspect they will come in the coming months.

A lot of the problem is the angle of the Sun in each view. With the LRO images the Sun is low in altitude, so the shadows of craters and depressions in the surface are prominent. With the lift off footage, the Sun is quite high in the sky and only craters with sharp defined edges and ramparts are visible. The attached image I have marked what I call "depressions" with red arrows. These are not very clear in the Liftoff footage as they don't have those defined edges.
