Tidal tomography reveals a thermal anomaly beneath Mars’s crustal dichotomy

Nature, Published online: 26 August 2026; doi:10.1038/s41586-026-10893-xAnalysis of tracking data from Mars orbiters reveals time-variable gravity field behaviour reflecting the structure underlying the Martian crustal dichotomy and indicates the preservation of a 200–400 °C thermal anomaly in the present-day mantle below the southern highlands.
