NASA's Curiosity rover finds ancient oasis on Mars 3.5 billion years in the making
A new study based on NASA's Curiosity rover's findings reveals that once upon a billion years ago, there was an oasis in Mars. One mystery remains- was there life? Scientists have determined a 100-mile wide crater using the rover's data. It was once dotted with small, salty lakes, and ponds some 3.5 billion years ago. A section of the crater known as 'Old Soaker' perhaps contains the clearest signs of an ancient oasis.
