Mars Express Gravity Results Plot Volcanic History

Five years of Mars Express (MaRS experiment) and Mars Reconnaissance Orbiter gravity mapping data are providing unique insights into what lies beneath the Red Planet’s largest volcanoes. The results show that the density of the lava changed over time and that the thickness of the planet’s rigid outer layers varies across the Tharsis region.
