Evidence suggests Mars once had rivers and vast oceans, but the water disappeared about 3B years ago when the planet lost its atmosphere. Some of it froze into ice, but scientists have long sought to learn where the remainder went. The data indicate that water filtered into the crust rather than escaping into space.Evidence suggests Mars once had rivers and vast oceans, but the water disappeared about 3B years ago when the planet lost its atmosphere.

According to a new research paper published on Monday based on data from NASA's InSight lander discoveries have found a vast reserve of liquid water beneath the planet's surface, indicating favorable conditions for possible microbiological life.
