Moon Images By SMART-1 Options

SMART-1 is approaching its operational orbit. ESA has released some images of the Moon on this page:

Ah, now i remember. I reread it and the idea is to spot rocket plume disturbance by the lunar module and do it in the same manner as they can do now with MGS (cPROTO: rolling the craft during overpass while keeping the imager on the same target can tripple the resolution in the direction of orbit). I did not know SMART-1 has this (fast and accurate) positioning capabilities though.....

A little side step: What would this cPROTO technique mean for MRO-images by the way ? I read that HiRISE has a resolution of about 50 cm/pixel. Would this mean that rolling procedures (enhancing line sampling time) could make images of 15 cm/pixel ?

Hey, 15cm resolution means to have a military spy-satellite around Mars!
Anyway, Marcel, I think that is not necessary to "fast and accurate positioning capabilities" in order to realize this:
if you use a CCD detector, it should be sufficient to set correct "timing" for row scanning and this would eliminate effect
of spacecraft motion (similar tecnique is used in some automated astronomical telescopes like "spaceguard survey" ones).
Anyway, if they really want to portrait LEM vehicles they should fly SMART very low (I calculated a mere 10Km height in order to
have 1m resolution!).
This is due to relatively wide angle used in the AMIE camera aboard this spacecraft...

10 km ? Could this be done ? There's no drag, so one could say yes.
