New research suggests Mars may have enough water under its surface to form a global ocean. Scientists detected over 1,300 marsquakes with NASA's InSight rover, indicating water may be hiding in cracks of rocks underground.
Key Points
Detection of over 1,300 marsquakes by NASA's InSight rover
Water believed to be underground in cracks of rocks
Water could have seeped from the surface billions of years ago
Large volumes of water believed to have existed on Mars over 3 billion years ago
Pros
Potential for habitable environments on Mars
Possibility of confirming the presence of water and potential life
Cons
Presence of water does not guarantee the existence of life on Mars
