Subsurfacewater on Mars defyexpectation

A recent study of seismic data from NASA's Mars InSight mission has uncovered a few surprises.

The first surprise: there is little or no ice in the upper 300 metres of the subsurface beneath the landing site near the Martian equator.

"We discovered that the crust of Mars is weak and permeable." The sediments are weakly cemented.

"These findings do not rule out the possibility that there are grains of ice or small balls of ice that are not glueing other minerals together."

The second surprise defies a widely held belief about what happened to Mars' water.

Early in its history, the red planet may have contained oceans of water.
