Robot discovered Curiosity of the US Aerospace Agency (NASA) recently discovered the largest amount of clay minerals since the robot was put on Mars in August 2012.
Curiosity was active again after being shutdown last week and stopped contacting Earth.
Despite the discovery of water sources, NASA robots will not be able to approach this area to collect data because of the risk of spreading harmful bacteria from the earth.
Scientists of the US Aeronautics Agency (NASA) are extremely interested in super sharp 'Mars' photos, recently captured and sent by 'Curious' robots.
