Salt water detected on Mars

Scientists discovered saline water on the surface of Mars, opening up the possibility of finding extraterrestrial life forms.

Salt water has been discovered on Mars

According to the University of Copenhagen, Denmark, the Curiosity autonomous device found Calcium perchlorate salt in the soil in the Gale crater area . Calcium perchlorate absorbs water vapor from the atmosphere under appropriate conditions. Based on data from Curiosity's weather control system, they determine the viability of these conditions at night and after the sun rises in winter.

When night falls, part of the water vapor in the atmosphere condenses on the surface as a frost, but calcium perchlorate absorbs water and forms saltwater , so the freezing point is lowered and frost can turn into substance. liquid.

"The new point in this study is that we have temperature and humidity measurements for a year, and now we have the data needed to show that water can be liquid and salty. ", IB Times yesterday quoted Professor Morten Bo Madsen as saying. Javier Martin-Torres, head of research, hopes liquid water can be found in many other areas across the red planet.

Scientists have long known that water exists on the red planet in the form of ice and once found evidence of liquid water on Mars.
