CTOnews.com, June 14 (Xinhua)-- after completing an important software update, NASA's Mars rover Curiosity took pictures of the Martian marked Valley (Marker Band Valley) on April 8 and made a "postcard."

This postcard is an artistic representation of the Martian landscape. It colors two black-and-white panoramic photos taken by Curiosity's navigation camera. The two images, taken at 09:20 and 03:40 Mars time, respectively, highlight the details due to differences in light. To enhance the effect, engineers also added blue in the morning and yellow in the afternoon, just like another similar postcard taken by Curiosity in November last year.

Curiosity is currently exploring the foothills of the three-mile Sharp Mountain in the Gale Crater, where it has been studying since landing in 2012. In the distance of the rut left behind is the "marked belt valley", which is a winding area located in the "sulfate-containing area". Here, Curiosity found unexpected signs of the existence of ancient lakes. Looking further into the distance (a little to the center and a little to the right), there are two hills, Bolivar and Dipdale, which Curiosity crossed while exploring the Palaitpuy Passage.

Doug Ellison, an engineer for Curiosity, said that during the Martian winter, there was less dust in the air, which also increased the depth of the shadows. "the shadows on Mars are clearer and darker when there is less dust and softer when there is more dust."

The image also shows Curiosity's three antennas and nuclear power sources, and the white circle in the lower right corner is the radiation Assessment probe (RAD), which has been helping scientists study how to protect the first astronauts landing on Mars from radiation from the planet's surface.
