In 1976, NASA’s Viking mission successfully landed the first spacecraft on Mars. When the mission began sending images from Mars’ surface back to Earth, scientists noted long, dark streaks on crater walls and cliff sides. To this day, some researchers suggest that the strange geographical features are the result of water flow—but a recent study says otherwise. Planetary scientists from Brown University and the University of Bern have used artificial intelligence to reveal that the enigmatic Mar

But decades later,
