Blue Patches on Mars are signs of salty water reacting with soil sediments

Some materials such as sediments turn to blue when they come in contact with slightly basic materials such as salty water. If you’re familiar with your litmus paper, you will know it turns blue when it comes in contact with basic materials and red or pink with acidic materials.

The blue patches are sediments that may have been exposed to salt water as they ooze up from the underground sources.

The proof can be clearly seen, but then I could be mistaken. We know for a fact that NASA is ultra-secretive concerning alien life forms and they’re not about to share those secrets unless it will benefit mankind.

Is this the case right here? We may not know the result until several years later.

A picture of two deep blue patches on the surface of Mars was captured by a European probe orbiting the Red planet. But looks may prove to be deceiving, they may look like lakes to the untutored eye, in reality they are layers of dark, volcanic rock that seemingly appears blue in the picture taken by the Mars Express spacecraft of the  European Space Agency.

This astonishing photo is a latest in the series of ‘blue’ images of blue auroras to a blue sunset of the red planet.

Mars gusts puffed dark sediment to the planet area. ESA in a statement said  that the blue hues are actually “optical illusion caused by the image processing.”

“The blue-hued patches lying within the ragged craters are actually dark sediments that have built up over time,” ESA declared.

The Mars Express controversial photo depicts the Arabia Terra section of the red planet. Craters in various sizes dot the region’s surface and a majority of the red planet. But, over time  those surface features may be eroded.

Marsian winds can at times reach up to 100 km/h or around 62 mph, thus creating dust storms lasting for days or weeks, ESA said. These heavy winds can wipe out features on the planet surface over a span of a million of year’s time, depositing material in other areas of Mars.

Even though these images may not depict evidence of liquid water on Mars, earlier findings from the  Curiosity Mars rover of NASA indicated that Mars was once a wet planet that could prove habitable for microbial life once upon a time in the planet’s past.
