Almost as 20 years, many alternative researchers claim that there is water on Mars and that it was a lifetime there long ago.

Until 15 years ago, most mainstream scientists would have sworn that there was never life on Mars, let alone water. Now, science has gradually worked its way from water in the form of vapors, through frozen ice caps, tiny ice crystals just below a thin layer of soil to liquid water below the surface.

It seems to me like a joke from the fairy tale, How the Princess Wakes Up, when Vladimír Menšík, in the role of Matěj's servant, says: "Here we look better!". So what will be the next phase? Will you find puddles of surface water in craters after sunset? And when will you admit the color (literally) and show the lakes and maybe the rivers?

There are so many factors that affect the existence of water. Temperature and pressure are just a few of the few. Moreover, the physical principles of the Earth are not the physical principles of Mars.

Quotes from the Czech Television portal:

Recent measurements made in Gale's crater show that there is liquid water beneath the surface of the red planet. Until now, scientists have believed that there are only ice deposits on the planet and that its climate is too cold for liquid water.

“We have had evidence to date that there could be permafrost water. But for the first time we are finding that there is also liquid water, ”said Professor Andrew Coates.

Recent findings show that the soil of Mars is moistened with liquid sodium chloride solution. It is the presence of salt that significantly lowers the freezing point of water - when mixed with calcium perchlorate, liquid water can exist even at temperatures around minus 70 degrees Celsius.

New measurements from Gale's crater show that during the winter nights until just after sunrise, liquid brine forms on the planet. This is created by the absorption of air humidity. "The soil is porous and we can see the water seeping down," says Mortem Bo Madsen of the University of Copenhagen, who is involved in the Curiosity project.

I applaud "trying" to stop making people stupid ... :)
