Nasa's Curiosity rover to search for briny liquid thought to cascade down nearby mountain

Finding water on Mars has been a dream of scientists for decades and could prove an essential resource for any human pioneers looking to colonise the red planet. Now Nasa is hoping its Curiosity Rover may finally be able to settle the question of whether the liquid still exists on the planet's surface. Scientists are dispatching the robot to explore a feature on a sandy hillside they believe could be their best chance yet of finding water on the red planet. Scientists are hoping to send the Curiosity Rover to investigate dark streaks that appear on the nearby Mount Sharp during the Martian summer. Last year Nasa confirmed'dark fingers' spotted by the Mars Reconnaissance Orbiter were likely to be made by liquid moving across the planet's surface.
