Water on Mars!!


Lat week, NASA had an announcement and most of you probably heard it.  So even though this is not breaking news anymore, it is still an exciting discovery.   We have been studying Mars for years and it has seen like a desert planet.  There is evidence that there was water on Mars in the past and even that water could be hiding on Mars under the surface.  So who would have ever thought that a planet only 9 months away with current technology could harbor water.

The new evidence shows dark streaks on the planet's surface that come and go depending on the season.  The evidence suggests this is water on the surface.   Many of the headline may make you think water is flowing on Mars, but the truth is that there are probably still not any oceans or even ponds on the surface of Mars.  The water that is showing in these recent pictures is more of a seeping to surface and only when the temperature reaches a balmy negative 10 degrees Celsius.  The water is not flowing like you might imagine a stream, but just getting enough of the surface wet enough to darken it.  The water also appears to be a little salty.

Even though we are probably not going to go to Mars and drink water from a spring, I honestly never thought there was any liquid water near the surface of Mars.  The pictures we see looks like a barren desert of rocks.  Where there is water there could be life even if only microbial life.  The discoveries we are now seeing in space keep coming.   If we are just starting to uncover mysteries from one of the closest celestial objects to Earth, just imagine what else is out there!
