Red Planet, White Winter


| 1 Comment

From 2006-2007, there was snowfall on the planet Mars. In 2008, scientists discovered that this was indeed the same sort of snow that falls here on Earth, made of frozen water.

 

This week, NASA's Mars Reconnaissance Orbiter found more snowfall, but this time, the snow is made of dry ice.  Dry ice is frozen Carbon Dioxide. Wow, big deal right, but it provides us a little perspective in regards to the Martian winter.

 

Carbon dioxide freezes at -193 degrees Fahrenheit (-125 Celsius).  If these numbers are any indication, this means that the winter on Mars, at least towards the north pole, is really cold. 

 

Why is this important? Well, NASA was thinking about sending humans to Mars, so this information is a warning to the astronauts that go there: they cannot land on and explore Mars during the winter, or else they will likely freeze to death.  This would also apply to any possible far-off plans to colonize the red planet.

 

Both endeavors are years away from even being considered seriously, and maybe scientists would have developed space gear that provides enough heat to survive in these extreme sub-zero temperatures by that time.  How do you think this discovery affects humanity's plans to go to, and someday colonize, Mars?

Snow on Mars?!? I thought there was still a question of water itself! This is shocking to me! If it snows does it also rain? Is it really like our precipitation? Why aren't there puddles or streams if it snows? So many questions!
