english: Mars, on the other hand, has been unprotected because of its lack of magnetic field, and over billions of years, maybe enough atmosphere has been stripped away to account for a transition from a habitable planet to the planet that we see today.
non_english: Mars, s druge strane, je bio nezaštićen zbog nedostatka magnetnog polja, i tokom milijardi godina je možda dovoljna količina atmosfere guljena do te mere da on pređe iz nastanjive planete do planete koju vidimo danas.
