orbital data of three spacecraft to map the gravity field of Mars. In this new map, low gravity canyons like Valles Marineris, in blue, stand out from the high-gravity reds and whites of the Tharsis mountains.
When the solar system settled into its current layout about 4.5 billion years ago, Mars formed when gravity pulled swirling gas and dust in to become the fourth planet from the Sun. Mars is about half the size of Earth, and like its fellow terrestrial planets, it has a central core, a rocky mantle, and a solid crust.

22 mar 2016 · Scientists have used small fluctuations in the orbits of three NASA spacecraft to map the gravity field of Mars. If Mars were a perfectly smooth sphere of uniform density, the gravitational pull experienced by an orbiting spacecraft would be exactly the same everywhere on the planet.
Using small fluctuations in the orbital data from three NASA spacecraft—Mars Global Surveyor, Mars Odyssey, and the Mars Reconnaissance Orbiter—scientists created a new map of Mars' gravity field. The map is the most detailed to date, and provides a revealing glimpse into the hidden interior of the Red Planet.
