The research team from California Institute of Technology (Caltech) and NASA's Jet Propulsion Laboratory (JPL) found that around four billion years ago, Mars was home to enough water to have covered the whole planet in an ocean about 100 to 1,500 metres deep; a volume roughly equivalent to half of Earth's Atlantic Ocean.
