NASA’s big news this week: Water On Mars!!! The surface of Mars is streaked with brine! This means water existed at some point in the past on the Red Planet in order for this salty substance to be created and still exists today! Should the gringa be prepared to pack a beach umbrella if added to the list of future Martian colonists? How about a bikini and fishing pole? Ummm, well, nope. Well, then, if not, what’s the big, darn deal? I mean, I have salty streaks down my face after a big cry. What’s it all good for other than skin irritation?
Well, wide-spread “perchlorate” salts are what the NASA scientists are actually so excited about. Well, what the heck are they? The gringa read the report that these salts were present because humidity and temperatures were just right on Mars. Mmm hmm. And? Because these salts are so absorbent, the freezing point of water is further lowered so it can remain liquid in colder than “normal” temperatures. Yes, I see. And your point is? This could theoretically “almost” prove… WHAT?! WHAT?! Proof of liquid on Mars. Aaaaargh! But the gringa wants to know WHY IS THAT IMPORTANT?!
Curiosly enough, one of the main uses of perchlorates on Earth is the production of propellants in rockets! Crazy, huh? It’s as if Mars is inviting us to come and is offering to pay for the gas!
It is also used to create “oxygen candles”. These items are used on spacecrafts, submarines and airplanes as an emergency oxygen supply. When these “candles” are burned, they produce oxygen. Is this not amazing to find an abundant supply of such a thing on a planet we would like to set up camp on and two things preventing this from happening are fuel and oxygen supplies! THIS IS AMAZING!
In order for perchlorates to be created, there had to be bacteria. This means that at one time life could be supported on Mars. This discovery is so significant not just for what it tells us of the history of the Red Planet but of its potential future!
If liquid water was once abundant on the surface of Mars, it is then possible that there is still frozen water underground and… this is important because… this could become a resource to assist the survival of long-duration space missions to Mars. Hurrah!
NASA reported earlier in 2015 that the northern hemisphere had probably been an ocean with a maximum depth of over one mile but that most of this precious resource had been lost to the effects of deep space. That discouraging news has now been overshadowed by this new revelation of the possibility of underground frozen water resources. And, that is not all!
The different colors of the striations in the satellite images indicate that salty water is only frozen some of the time. It is possible that Mars experiences a warm season that would thaw this frozen brine and salt water would then be flowing freely down the mountainsides of Mars. This would occur when temperatures would rise to a “toasty” range just above 10 degrees Fahrenheit. So, the gringa won’t pack the fishing pole and beach umbrella, but, rather, a ski bunny outfit and river raft!
