New research reveals that Mars may have large liquid water reserves deep beneath its surface, reigniting hopes of finding extraterrestrial life. Using NASA’s InSight lander and seismic wave observations, scientists predict that water might occupy a 1-2 km-deep ocean in the Martian crust, 11.5–20 km below the surface.
Calculations in the Proceedings of the National Academy of Sciences suggest cracked rocks may hold large amounts of water. Dr. Vashan Wright of the Scripps Institution of Oceanography says this volume of water exceeds past predictions of ancient Martian oceans, shedding light on the planet’s history and habitability.
Water is essential for biological functions but does not ensure life. Researchers say that if liquid water aquifers exist on Mars, they could be great targets for life discovery, like water on Earth.
The report encourages more research to confirm these findings and determine how this water may affect Mars missions. While accessing these deep deposits may be difficult, Mars’ potential for life in subterranean oceans is tantalising.
