A new road review -a thousand satellite images showed: the dark stripes on the slopes of Mars were not traces of liquid water, as before thought, but the effect of dust and wind.
Dark stripes that appear and disappear on the slopes of Mars – from craters to volcanic cliffs – for decades are considered possible evidence of the presence of liquid water on the planet. However, a new major -school study published in the nature of nature denied this hypothesis. Writes Reuters and IFL Science.
“Our review shows that there are no signs that these stripes are associated with water,” said Adomas Valanins, a planet from the University of Brown.
Researchers have reviewed more than 87,000 shots of satellite, recognizing nearly half a million such stripes – though the real value, according to estimates, can reach two million. Despite the external resemblance to traces of liquid flow, these forms do not exceed a mirror of dust that moves under the influence of air.
“Having a global card, we were able to compare it to other data: temperature, humidity, wind speed, shift, surface hydration,” explained Valentin Bickel, another study.
It is narrow in the field for search for extraterrestrial life: now it is clear that these slopes do not promise areas for water detection or biological activity.
The greatest failure is caused by the RSL -a period of stripes that appear on the tag -day and disappear in the winter. For a long time they were considered evidence of the seasonal digestion of salty water. But they, according to scientists, have “dry” origin.
“If stripes are formed due to salty water, these are the potential habitat of microns. But once we do not see any connection with moisture, temperature or solar orientation,” Valanx added.
Now scientists know where it is not worth finding water, and therefore traces of life.
“This is a great advantage of our approach: we can deny some hypotheses before flying missions,” Valentine’s summary.
Earlier it was reported that scientists found the largest organic compound in Mars, discovered on the Red Planet.
