Mars May Be Far More Geologically Complex Than We Ever Imagined

Bedtime Astronomy

New research suggests Mars may have had a surprisingly complex geological past. Seismic data from NASA’s InSight mission reveal evidence of ancient magma movement deep beneath the crust, challenging the idea that plate tectonics are necessary for geological complexity.

The discovery could also reshape how scientists think about the potential habitability of rocky worlds beyond Earth.
