Water on Mars? Mysterious Dark Streaks Aren’t What Scientists Thought

NASA in 1976 Viking mission Successfully lowered the first spacecraft in Mars. When the mission began to send footage from the surface of Mars, scientists noted long, dark strips on the chambers and the sides of the abyss. To date, some researchers are the result of water flow of strange geographical features, but the last investigation is said differently.

Planetary scientists from the Brown University and Bern University, mysterious Martian, not the flow of water, but the wind and dust, use the wind and dust. The results are important effects for future MARS intelligence, as well as continuous search for life and life where humanity lives outside the earth.

Some sloping stripes last a long time, others are repeated sloping slope lineae (RSL) – More Ephemeral in the same locations in the hottest times of the year. While Mars is usually dry coldly (Fahrenheit, or -153 degree of Fahrenheit, which is a temperature -25 degree), can mix small amounts of water than potential ice, underground resources or humidity salt to be liquid and flow down a slope. The water is the main ingredient for life on earth, such compounds can also represent residential areas on the red planet. However, some researchers claim that instead of dry processes can create these features.

To resolve the issue Researchers taught an algorithm in a database on images of approved sloping strips learn Nature was published on Monday. Then they used the algorithm to scan 86,000 high-resolution satellite images and draw a map of Martian sloping strips.

“After this global map, we can compare it with databases and catalogs of other things, like temperature, wind speed, moisturizing, rock slide, and other factors,” Valentine Bickel, research co-author and Bern Bern University Bern University at Brown University statement. “Then we can look for correlations after hundreds of thousands to better understand the conditions where these features are.”

Simply put the consequences, the slope strips and RSLs with properties showing the existence of liquid or frost. Instead, researchers found that both sloping strips and RSLs developed in areas with high wind speed and dust collapse. In other words, it is likely that the dust layers triggered by the external forces, the dust layers are expected to cause a dry process.

Another failure of these results in search of surface life explains that the planetary scientists are weighted for future MARS research. The sloping strips have confirmed the theory caused by water, and as a result, the region may be a kind of life form, NASA, then fled the area. Because scientists, space ships and rovers, such as germs that can be contaminated, maybe the life life and Marti may hinder our lives.

“This is the advantage of this great information approach,” said Adomas vantantines, a planetary scientist in the Brown University specializing in the research author and Martian geology. “This helps us to exclude some hypotheses from orbit before sending a spacecraft to discover.”

In an obsessive visible industry by finding Water in MarsThe study stands as a reminder that every scientific progression is not needed to be in life.
