The picture, taken by the powerful HiRISE camera, has focused attention on Mar’s polar region. However, the trees are nothing but an optical illusion.
Latest pictures from NASA’s Mars Reconnaissance Orbiter show hilly desert area with islands of trees on Mar’s surface.
The orbiter, which was commissioned to search for water on the planet, took the images that show a thin coating of frozen carbon dioxide or dry ice.
However, the trees are nothing but an optical illusion.
NASA’s Candy Hansen told The Sun, “The streaks are sand, dislodged as ice evaporates, which slide down the dune. At this time of the Martian year the whole scene is covered by CO2 frost.”
“The color of the ice surrounding adjacent streaks of material suggests that dust has settled on the ice at the bottom after similar events,” he added.
