The flyby uses 3D data gathered from HiRISE, the 0.5-meter reflecting telescope on board NASA's Mars Reconnaissance Orbiter. The 3D data set was calculated by comparing HiRISE's ultra-crispy images taken from two different points of view. The photos were matched using picture recognition software and converted in a 3D surface map using the position of the orbiter. The result is the most accurate terrain information on the surface of Mars yet. The best thing: All this data is being published by NASA for everyone to use.
Now, could somebody please make a two hour version on full IMAX with David Bowie's music, please.
