Mars' gravity, released as in new map by NASA. This will be helpful for future space programs to Mars. Scientist believed that this new gravity map gives the idea about how the red planet shaped.
Antonio Genova, MIT and NASA Goddard Space Flight Center said,"Gravity maps allow us to see inside a planet, just as a doctor uses an X-ray to see inside a patient."
"Mars has a liquid outer core of molten rock." The researchers determined this by "analyzing tides in the Martian crust and mantle caused by the gravitational pull of the sun and the two moons over Mars."
