<p>Hi all,</p><p> Suppose we were to pump up the Martian atmosphere to something nice like 0.5bar, what sort of time scale are we looking at for it to deteriorate again to 0.1bar (for example, assuming no more gasses are added in that time)?</p><p>Is there a relatively straightforward way of calculating such a thing based on strength of gravity / diameter / atmospheric composition and distance from the sun? </p><p> Also, will the mass of Earth's atmosphere decrease significantly over the next hundred million years (discounting other processes)? </p> <div class="Discussion_UserSignature"> </div>
