Der Mars könnte einen Wasser im Wert von Ozean unter seiner Oberfläche haben. Seismische Daten deuten darauf hin, dass die seismischen Lesungen des Innenraums des Mars stark große Mengen an Wasser, die 6 bis 12 Meilen unterirdisch begraben sind.

Persuasive new evidence supporting the possibility of liquid water deep underground on Mars has come to light in a new analysis of seismic data from NASA’s InSight lander.

In 2024, researchers proposed that the deep subsurface of the [Red Planet](https://www.space.com/the-universe/mars/what-makes-mars-the-red-planet-scientists-have-some-new-ideas), particularly between 7.1 and 12.4 miles (11.5 and 20 kilometers) down, [is soaked in liquid water](https://www.space.com/the-universe/mars/oceans-worth-of-water-may-be-buried-within-mars-but-can-we-get-to-it), a conclusion they base on the velocities of seismic waves detected during [marsquakes](https://www.space.com/mars-marsquake-strongest-ever-2022-cause).

Now, researchers Ikuo Katayama of Hiroshima University and Yuya Akamatsu of the Research Institute for Marine Geodynamics in Japan have found supporting evidence for this claim of liquid water deep inside [Mars](https://www.space.com/47-mars-the-red-planet-fourth-planet-from-the-sun.html). „Many studies suggest the [presence of water](https://www.space.com/17048-water-on-mars.html) on ancient Mars billions of years ago,“ said Katayama in a [statement](https://www.geosociety.org/GSA/News/pr/2025/25-03.aspx). „But our model indicates the presence of liquid water on present-day Mars.“

Interesting. A lot easier to dig deep on Mars too, as the rock isn’t as hot (and therefore semi-liquid) as it is on earth. If we do want to put a colony on Mars going underground makes a lot of sense, so having some deep boreholes to extract water would not be a bad idea. Instead of terraforming you could build towards a ‚cavern arcology‘ civilisation, which would be cool.
