NASA Has Just Released Breathtaking New Photos of Mars And They Are Marvellous

People are curious by nature. Sometimes the potentials of this curiosity in our lives can be revealed in a bad way. Sometimes being smarter and more equipped. In the case of NASA, it has always been fascinated by Mars. Countless satellites and space shuttles have been sent to the Red planet and while some of them haven’t exceeded the expectations placed before them, some have.

On Earth, Bourke had done previous studies of dunes in the Namib Desert near Walvis Bay, Namibia and noted "arctuate striations" — crusty arcs of sand cemented by water and minerals — on the surfaces of migrating sand dunes using photos taken by satellite. She subsequently assembled a team to check them out on the ground and discovered that the striations resulted when dune materials had been chemically cemented by salts left behind by evaporating groundwater. "On Earth, desert dune fields are periodically flooded by water in areas of fluctuating groundwater, and where lakes, rivers and coasts are found in proximity," said Bourke. These periodic floods leave tell-tale patterns behind them." Once the material had been cemented, it hardens and remains behind as the dunes continue to migrate downwind.
