As promised, NASA made a huge announcement regarding Mars thanks to its Mars Atmosphere and Volatile Evolution mission, or MAVEN. It revealed that the Martian atmosphere is thinning at a fast rate every second. The culprit? The same solar winds that whip our system, including Earth. The data gathered by MAVEN can help scientists piece together the mystery of how Mars become the cold and arid planet it is today, and perhaps offer hints about future habitable planets in solar systems much similar to ours.
