   Could water escape from Mars?

   • But Mars' magnetic shield is weak and could have allowed elemental components of water to escape from the planet. But the rate at which hydrogen - one chemical constituent of water - escapes from that atmosphere today suggests this can't be the whole story.

   What is the ion escape rate from Mars?

   • The escape flux of all O species observed from Mars today by MAVEN is around 6 × 10 25 atoms per second 28, 78, 79. Past escape rates of O (from both H 2 O and CO 2) were probably larger via a combination of enhanced dissociative recombination, ion escape and ion sputtering 28, 80, 81, 82.
