Curiosity rover finds evidence of Martian atmospheric loss

Authors


Abstract

Researchers think that roughly 4 billion years ago, the atmosphere of Mars started to wither away, blasted into space by the solar wind and other forces. This atmospheric loss transformed Mars from a warmer and wetter planet to its current cold, arid state. As time progressed, Mars lost at least half but probably as much as 95% of its atmosphere.
