Seismic data from NASA’s Insight Lander has unveiled a significant reservoir of liquid water deep beneath Mars’s surface. Previous research confirmed frozen water at the planet’s poles and water vapour in its atmosphere. However, this marks the first discovery of liquid water on Mars.
Prof Michael Manga from the University of California, Berkeley, highlighted the importance of this discovery. He explained that water is crucial in shaping a planet’s evolution, addressing the mystery of where Mars’s water disappeared.
Evidence from various studies has shown that ancient rivers and lakes once existed on Mars, but the planet has been dry for three billion years. The loss of its protective atmosphere led to the evaporation of surface water. Prof Manga noted that much of Earth’s water is underground, suggesting a similar scenario for Mars.
This finding hints at the potential for habitable environments deep below the Martian surface. Understanding Mars’s water cycle is essential for comprehending the planet’s climate evolution, surface conditions, and interior.
NASA’s Insight mission, which ended in December 2022, recorded seismic waves on Mars for four years. The lander detected nearly 1,319 quakes, allowing scientists to infer the underground material composition. These findings appear in the Proceedings of the National Academy of Sciences.
The techniques used by Insight are similar to those employed on Earth to search for water, oil, and gas.
Frequently Asked Questions
Here are some common questions asked about this news
Has liquid water been found on Mars?
Yes, NASA’s Insight Lander discovered a huge reservoir of liquid water deep under Mars’ surface.
Where was water previously found on Mars?
Previous studies found frozen water at the Martian poles and evidence of water vapor in its atmosphere.
Why is the discovery of liquid water on Mars important?
It suggests the possibility of discovering habitable environments deep underground, crucial for understanding Mars’ evolution.
How did Mars lose its water?
Mars lost its water to the sun after losing its atmosphere, which acted as a protective blanket.
What techniques were used to discover the water on Mars?
Scientists used seismic waves recorded by NASA’s Insight Lander, similar to methods used on Earth for water and oil exploration.
