Trouvelot Crater in the Mars highlands of Arabia Terra
Trouvelot Crater in the Mars highlands of Arabia Terra
Between the two large outflow valleys of Ares Vallis and Mawrth Vallis lies the highland region of Arabia Terra. One of the oldest landscapes on Mars, it consists of craters formed approximately four billion years ago by impacts from asteroids of varying sizes. The true-colour images from Mars Express show an area of 25,000 square kilometres – nearly the size of Brandenburg. The right half of the image is dominated by the near 150-kilometre-wide Trouvelot Crater, which likely contained a lake in the planet's early history.
