How did the Curiosity rover weigh a mountain on Mars?

2019, Feb 06    

The Curiosity rover on Mars has some pretty amazing experiments aboard, but curiously enough never had a gravimeter, a device used for measuring the gravitational pull of buried rocks. So how then did scientists manage to weigh a mountain on Mars using years-old data taken by Curiosity? Charlie brings in a paper that reads like a data analysis version of a MacGyver episode.

Check out the original paper in Science here and the New York Time article (with great photos) here.
