The Lost Ocean of Mars

From SciTechDaily's 5-16-25 article entitled "Scientists May Have Found a Massive Ocean of Water Deep Beneath Mars’ Surface":

Scientists have uncovered a seismic signature beneath Mars’ surface that hints at something astonishing—liquid water may still exist in the planet’s upper crust.

This exciting research comes from an international team of scientists: Dr. Weijia Sun and Dr. Yongxin Pan from the Institute of Geology and Geophysics at the Chinese Academy of Sciences, Dr. Hrvoje Tkalčić from the Australian National University, and Dr. Marco G. Malusà from the University of Milano-Bicocca [...].

[T]he team of geologists and geophysicists turned their focus to the planet’s crust. They suspected that its internal structure could hold the key to finding hidden water. Using seismic data from NASA’s InSight mission, the scientists analyzed the wave patterns created by two massive meteorite impacts (named S1000a and S1094b) and the largest marsquake ever recorded (S1222a).

Their analysis revealed something remarkable—a zone 5.4 to 8 kilometers deep where seismic waves slowed down significantly. This slowdown could mean the presence of liquid water at the base of Mars’ upper crust.
