European Scientists: Frozen Sea Below Martian Surface

Geographic features on the Martian surface imply a frozen sea just below the surface.

The Mars Express spacecraft has taken photographs of Mars' equatorial region Elysium that suggest a frozen sea lies below the surface. It is believed that a cataclysmic flood event engulfed the area millions of years ago, and ice later froze the sea. Since then, dust coated the surface, hiding the sea beneath a thin layer. The water is thought to have originated from subterranean eruptions at the fractures of Cerberus Fossae. Many hope the European Space Agency will send its next lander there. Some see this as evidence that life not only thrived previously on Mars, but that some microorganisms may still exist there.
