NASA has released an incredible Mars gravity map, based on data collected from three spacecraft.
“Gravity maps allow us to see inside a planet, just as a doctor uses an X-ray to see inside a patient,” said Antonio Genova of the Massachusetts Institute of Technology (MIT), Cambridge, Massachusetts, in a statement released by NASA. “The new gravity map will be helpful for future Mars exploration, because better knowledge of the planet’s gravity anomalies helps mission controllers insert spacecraft more precisely into orbit about Mars.”
Genova, who is based at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is lead author of a paper on the Mars Gravity research published in the Journal Icarus. “The improved resolution of our gravity map will help us understand the still-mysterious formation of specific regions of the planet,” he added, in the NASA statement.
