Before the 8 rover missions that expanded our knowledge of Mars, a lot has been speculated about the red planet. It used to be that people believed extra-terrestrial beings lived there, some even theorized that our own species originated on Mars, while most of the ancient civilizations named their gods of war after it.
We nowadays know a lot about Mars, thanks to not only the rovers that walked its surface, but also due to the extended research and observation of our nearest neighbor. This extensive research has gathered some pretty interesting information about Mars over the years and we would do well to take notice of some of the most interesting facts we currently know about it.
24Snow on Mars gets vaporized before reaching the ground
Mars may be a desert, but it is a very cold one. Due to the fact that it is lacking an atmosphere, the difference in temperature from the surface of Mars and the temperature just a few meters off the ground is very big. For instance, the temperature on Mars is -153 degrees Celsius at the poles and 20 degrees Celsius at the equator, and this is at ground level. This is precisely why every time it snows on Mars, the snow vaporizes in mid air sort of speak.
