With all the attention being paid to Mars, we are learning something new about the red planet almost daily. Each new revelation is pretty heady information. But what about the weather on our celestial neighbor? One of the most common questions that people have is whether Mars is hot or cold.

The early days of Earth was marked by a climate that was both warm and wet, and mirrors what Mars was like some 3.5 billion years ago. However, with the atmosphere on Mars consisting primarily of carbon dioxide and water, a series of chemical reactions occurred at some point in the distant past that caused the formation of carbonate rock. The smaller size of Mars and its lack of a tectonic system precluded the recycling of the rock back into carbon dioxide. For this reason, the atmosphere of Mars has become exceptionally thin.

So is Mars hot or cold? A thin atmosphere means that the temperatures tend to be very cold. Any water that might remain on Mars is therefore frozen in the Martian poles as permafrost or hidden deep underground in a spring system.
