On March 21, 2016, NASA revealed a new Mars Gravity Map. It was created using data from NASA's Deep Space Network and the following spacecraft: Mars Global Surveyor, Mars Odyssey, and Mars Reconnaissance Orbiter.

On this color-coded map, white indicates higher-gravity areas and blue indicates lower-gravity areas. The data has enabled researchers to look inside the planet and has confirmed that Mars has a liquid outer core of molten rock.
