Northern Dunes (EDM - Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunexit Team)
|
The Dunes visible in this EDM are approximately 100 meters across and they are traversing a bumpy, hard Terrain. Polygonal Patterns are evident in some areas while numerous meter-scale Boulders are strewn throughout the whole Region. The Boulders are more numerous in areas where the Polygonal Patterns are less pronounced. Repeated imaging of this large Dunefield shall reveal whether these Dunes are presently moving (so-called "Migrating Dunes") or not.
Mars Local Time: 14:42 (Early Afternoon)
Coord. (centered): 73,622° North Lat. and 328,215° East Long.
Spacecraft altitude: 316,7 Km (such as about 198,0 miles)
Original image scale range: 63,4 cm/pixel (with 2 x 2 binning) so objects ~ 1 mt and 90 cm across are resolved
Map projected scale: 50 cm/pixel
Map projection: POLAR STEREOGRAPHIC
Emission Angle: 1,9°
Sun - Mars - MRO (or "Phase") Angle: 57,6°
Solar Incidence Angle: 56° (meaning that the Sun is about 34° above the Local Horizon)
Solar Longitude: 117,4° (Northern Summer - Southern Winter)
