The absolutely critical thing with a camera like HiRISE is the image must smear nearly perfectly across the detector parallel to the cross-frame rows of pixels and the camera must step the "bucket" of electrons along the column in near perfect time with the image motion, and nothing can jiggle during the imaging. "Nearly perfectly" is probably somewhat better than 1/4 pixel or so. That would be measurable but not obviously degrade the image.
That HiRISE did so well from a grossly non-nominal elliptical orbit under low to extremely low sun illumination angles and did so with "first try" image aquisition software and decalibration files and software says that barring hardware failure, we've got ourselves a winner. The only sad thing is that the "phace-phreaks" will still be able to "discover" untold signs of archaeological wonders at and well beyond the resolution limits of the images, no matter how high the resolution is. Hoaxland would be able to discover signs of artificial intelligence in the artifacts of an image of a single electron, I'd swear! |
