Post: Mars’ Atmosphere Was Destroyed Billions Of Years Ago


The cold and dry planet of Mars is dominated by carbon dioxide that resides inside a thin atmosphere. According to new data from NASA’s Mars rover Curiosity, the planet has been that way for nearly 4 billion years.

Currently Mars’ atmosphere is only one percent as thick as Earth’s atmosphere. So perhaps there never were Martians on Mars. Potential alien life forms may not have had an environment that was hospitable to the formation of life.

While the low atmosphere would make it hard to survive, the rover Curiosity did discover that humans could withstand the planet’s radiation levels.
