Unlocking Mars’ hidden water: A game-changer for exploration and the search for life

Recent studies suggest Mars may hold vast amounts of water beneath its surface

Mars has long fascinated scientists and the public alike, especially regarding its water history. Recent studies reveal that the Red Planet may hold far more water than previously believed.

This article explores the latest findings about Martian water, its implications for future exploration, and what it means for the possibility of life on Mars.

Water reserves on Mars

For years, Mars was thought to be a dry, barren world. However, new research suggests that a significant amount of water remains trapped beneath its surface.

According to a study by scientists at the California Institute of Technology, between 30% to 99% of Mars’ original water is still there, hidden within the planet’s rocks and minerals, rather than escaping into space.

The term Global Equivalent Layer (GEL) is used to measure the amount of water on Mars. This unit expresses how deep the water would be if spread evenly across the planet. Current estimates suggest that Mars has a GEL of about 30 meters (100 feet), primarily found in polar ice caps and underground reservoirs.

The discovery of liquid water

Recent seismic data from NASA’s InSight lander revealed that Mars has a vast underground reservoir of liquid water. This water is located in tiny cracks and pores within rocks, approximately 10 to 20 kilometers (6 to 12 miles) below the surface.

Scientists estimate that this groundwater could cover the entire planet to a depth of 1 to 2 kilometers (about a mile) if it were brought to the surface.

This discovery is exciting because it suggests that Mars may have once been a much wetter planet, potentially capable of supporting life.

Evidence such as ancient river channels and lake deposits indicates that water flowed on the Martian surface billions of years ago, before the planet lost its atmosphere and much of its water.

Understanding the location and amount of water on Mars is crucial for future exploration missions. If humans are to visit Mars, knowing where to find water will be essential for survival.

While the underground water is challenging to access, it could provide valuable resources for astronauts. Heating Martian rocks could release water, but this method would require significant effort and resources.

The search for life

The presence of water is a key factor in the search for life beyond Earth. While the water on Mars is mostly trapped in minerals, scientists believe …
