The Cool Facts About Water On Mars

The search for water on Mars has been a long and arduous journey, but a very rewarding and fulfilling one. Less than 50 years ago, scientists could only speculate about the presence of water on the Red Planet. These days, scientists have found multiple pieces of evidence that water firstly – did exist on Mars – and secondly – still does exist. The discovery of the polar ice caps was one of the first confirmations of water on the planet, albeit in frozen form.

Fast-forward a few years and scientists found evidence of more frozen water below the surface (closer to the equator) and even flowing salty water on the planet’s surface. (Also, excitingly, scientists believe there are channels on Mars where water ten times greater than the average discharge of the Amazon River, the largest on Earth, was discharged.) The search for water on Mars is a worthwhile endeavor, largely because where there’s water, life has the possibility to exist.

In search of that, the year 2020 will see a new NASA rover take off from Earth to look for evidence of life formerly existing on the planet. For these and other exciting facts about H20 on Mars, strap on your spacesuit because here are 5 Facts About Water on Mars.

A rover finds liquid water globules

In 2008, the stationary Phoenix rover was examining the Martian surface and dug up chunks of a bright substance which disappeared over the course of four days. Scientists concluded, also based on two of the spheroids merging together, that the substance was likely liquid water which went on to evaporate.

Snow falls on Mars!

During the 2006-2007 Martian winter, snow fell on Mars, but it’s not exactly what you might be thinking. Carbon dioxide snow clouds noticed above the south pole were depositing carbon dioxide snow onto the surface below, the only place in the solar system where this is known to occur.
