Dark5 presents a mysterious space documentary that explores five of the strangest photos taken on Mars... including images of a stone circle that could be linked to Stonehenge on Earth, an unexplained deep hole formed by an unidentified underground cavern, a tiny blue speck that is the Curiosity Rover and the tiny "Mars blueberries" that have been seen by NASA's rovers, mystery streaks of heat emanating from impact craters, and possible evidence that Mars's crust was once soaked in water and had an ancient molten core that supported a magnetic field to protect life on Mars.
