Dunes-Nili_Patera-PIA13535.jpgLarge Dunefield in Nili Patera (Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)105 visiteDeve ASSOLUTAMENTE esserci qualcosa di "speciale" in questo grande Campo di Dune posizionato nei pressi della Nili Patera, dato che TUTTI gli Orbiters disponibili (da MGS a MRO, senza dimenticare Odyssey e Mars Express) hanno ripreso e riprendono immagini su immagini di queste coordinate.

Che cosa sar� mai?

Probabilmente si tratta di leggeri movimenti delle Dune (che potrebbero essere tutte "Migranti"), oppure - se andiamo su risoluzioni maggiori - potrebbe trattarsi di cambiamenti di forma e caratterizzazione delle Dune stesse.
Ho fatto una piccola indagine ed ho trovato del materiale NASA interessante qui (http://www.nasa.gov/mission_pages/MRO/multimedia/pia12860.html) e qui (http://www.nasa.gov/mission_pages/MRO/multimedia/pia12858.html).

Per chi fosse interessato... Buona lettura!2 commentiMareKromium

This Summer image shows the Dunes totally free of Frost.

This VIS image shows how complex the inter-dune areas are.

Dunes-North_Polar_Features-PIA13663.jpgExtremely unusually-looking Surface Feature near the North Pole of Mars (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)155 visiteCaption NASA:"Although this may look like a hostile alien lifeform, it's actually a complex line of Sand Dunes near the Northern Ice-Cap of Mars. The image covers an area about 10 Km (a little more than 6 miles) wide. It was taken in April 2006 by the Thermal Emission Imaging System instrument on NASA's Mars Odyssey Orbiter. It is part of a special set of images marking the occasion of Odyssey becoming the longest-working Mars Spacecraft in history.
The pictured location on Mars is at approx. 82,4� North Latitude and 314,5� East Longitude".6 commentiMareKromium
