This made Red Planet uninhabitable
The Martian surface may have reacted with and absorbed the water that once flowed on the Red Planet,
making it uninhabitable, scientists suggest.
Although today’s Martian surface is barren, frozen and uninhabitable, a trail of evidence points to a
once warmer, wetter planet, where water flowed freely. The conundrum of what happened to this water is long-standing
Previous research has suggested that the majority of the water was lost to space as a result of the collapse
of the planet’s magnetic field when it was either swept away by high-intensity solar winds or locked
up as sub-surface ice. However, these theories do not explain where all of the water has gone.
Convinced that the planet’s mineralogy held the answer to this puzzling question, scientists from the
Oxford University in the U.K. applied modeling methods used to understand the composition of Earth
rocks to calculate how much water could be removed from the Martian surface through reactions with
The results revealed that the basalt rocks on Mars can hold approximately 25 percent more water than
those on Earth, and as a result drew the water from the Martian surface into its interior.
