At the European Geosciences Union General Assembly 2013, held in Vienna, Austria, some members of Mars Rover Curiosity mission team have shown some discoveries concerning Mars atmosphere. In particular, they found new evidence that in the past the red planet had a much thicker atmosphere that has been lost over time until it reduced to about 1% of the Earth’s one at sea level.
