From the paper in the article:

>"MAVEN has observed the Martian upper atmosphere for a full Martian year, and has determined the rate of loss of gas to space and the driving processes; 1–2 kg/s of gas are being lost."

That sounds similar to earth's?

Earth's is more like 3kgs if I remember correctly
