Mars Reconnaissance Orbiter is two for two in the amazing feat of capturing photos of landers descending to the surface of Mars. This version was released several days after the landing; it has been corrected for optical blur.
This image was given special processing by members of the HiRISE Team, that included removing detector noise and optical blur. The sharpening was achieved by converting the image to its frequency components, correcting for the minor blur that was characterized by pre-flight laboratory measurements, and converting back.
