Liquid Water Discovered Deep Within Mars, Reviving Hopes for Life

Tuesday, 13 August 2024, 12:00

Recent research by geophysicists indicates the existence of liquid water beneath the Martian surface, based on four years of seismic data from NASA's Mars Insight Lander. The findings suggest that the mid-crust of Mars contains fractured igneous rocks saturated with water, challenging previous theories about the planet's water loss. With estimates of enough liquid water to form a half-mile deep layer across Mars, this discovery could significantly impact future missions to the planet, including potential human colonization efforts. However, accessing these water reservoirs will be a formidable challenge.

Liquid Water Discovered Deep Within Mars, Reviving Hopes for Life

Discovery of Liquid Water on Mars

Recent findings by a team of geophysicists suggest that there is liquid water located deep beneath Mars' surface. The research, which was published in PNAS, provides insights into the planet's geological history and potential for supporting life.

Methodology

  • The team analyzed four years of data from NASA's Mars Insight Lander.
  • They examined seismic velocities, which allowed them to infer the materials that seismic waves traveled through.

Key Findings

  • Evidence suggests that Mars' mid-crust is composed of fractured igneous rocks holding liquid water.
  • Estimates reveal that there might be enough liquid water to create a layer half a mile deep across the planet.

Importance of Water for Life

Prof. Michael Manga from the University of California, Berkeley, emphasized that the findings challenge the notion that all Martian water has been lost to space. Historical features on the surface suggest that lakes and rivers were present around three billion years ago, which raises essential questions about Mars' ability to support life.

Challenges Ahead

  1. Accessing these subterranean water reservoirs poses significant engineering challenges.
  2. Seismic measurements indicate that the water is located 7 to 12.5 miles below the surface.

While these discoveries are promising for future missions to Mars, including potential colonization efforts, the harsh conditions and depths needed to reach this water mean that human exploration will not be easy.
