Some images of stark Martian landscapes provide visual appeal beyond their science value, including a recent scene of wind-sculpted features from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter.

The scene shows dunes and sand ripples of various shapes and sizes inside an impact crater in the Noachis Terra region of southern Mars. Patterns of dune erosion and deposition provide insight into the sedimentary history of the area. (more…)

The earliest known image of an Egyptian ruler wearing the “White Crown” associated with Egyptian dynastic power has been brought to light by an international team of archaeologists led by Egyptologists from Yale University.

Carved around 3200 BCE, this unique record of a royal celebration at the dawn of the Egyptian dynastic period was found at a site discovered almost a half-century ago by Egyptologist Labib Habachi at Nag el-Hamdulab, on the West Bank of the Nile to the north of Aswan. (more…)

Northern Mars Landscape Actively Changing

Sand dunes in a vast area of northern Mars long thought to be frozen in time are changing with both sudden and gradual motions, according to research using images from a NASA orbiter.

These dune fields cover an area the size of Texas in a band around the planet at the edge of Mars’ north polar cap. The new findings suggest they are among the most active landscapes on Mars. However, few changes in these dark-toned dunes had been detected before a campaign of repeated imaging by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter, which reached Mars five years ago next month.
