Salt, clay and even snoring are some of the amazing revelations left by the expeditions to the red planet.
The last missions carried out on Mars have reached amazing and incredible revelations of the intimacy of the red planet.
We present the strangest objects, according to data collected by CNN, on the only planet that is emerging as the substitute for housing, in the future, a new home for the human race:RELATED
Gilbert V. Levin, who was a principal investigator in a NASA experiment that sent the unmanned Viking missions to Mars in 1976, recently published an article in Scientific American in which he argues that the positive results of the experiment were proof of life. On the red planet.
In the experiment, Viking probes put nutrients in the soil samples of Mars; if there were life, it would consume food and leave gaseous traces of its metabolism, which radioactive monitors would detect. To ensure that it was a biological reaction, the test was repeated after altering the soil, which would be lethal to known life.
This year, NASA's "rover Curiosity" found sediments containing sulfate salt in the crater, suggesting that it once had salty lakes in the Gale crater, an ancient lake bed with a mountain in the center.
These salts, according to the researchers, are evidence of the evaporation of the crater lake in the arid environment of the red planet. They also believe that studying younger rocks in the future could shed more light on how the Martian surface dried up.

This self-portrait of NASA's Curiosity Mars rover shows the vehicle at a drilled sample site called "Okoruso," on the "Naukluft Plateau" of lower Mount Sharp. The scene combines multiple images taken with the rover's Mars Hand Lens Imager (MAHLI) on May 11, 2016, during the 1,338th Martian day, or sol, of the rover's work on Mars. In front of the rover is the hole, surrounded by grayish drill cuttings, created by using Curiosity's drill to collect sample rock powder at Okoruo, plus a patch of powder dumped onto the ground after delivery of a portion to the rover's internal Chemistry and Mineralogy ( CheMin) laboratory instrument. . The rover team compared the rock powder from drilling at Okoruso to material from the nearby "Lubango" drilling site, which is visible behind the rover, just to the left of the mast. The Lubango site was selected within a pale zone, or "halo," beside a fracture in the area's sandstone bedrock. Okoruso is in less-altered bedrock farther from any fractures. Note that the Okoruso drill cuttings appear darker than the Lubango drill cuttings. The Lubango sample was found to be enriched in silica and sulfates, relative to Okoruso. To the left of the rover, in this scene, several broken rocks reveal grayish interiors. Here, Curiosity was driven over the rocks in a fracture-associated halo, so that freshly exposed surfaces could be examined. An upper portion of Mount Sharp is prominent on the horizon. . PC – NASA
In August of this year, CNN learned that the Curiosity rover made findings in the same Gale crater related to clay in the bed of that ancient lake. During the summer, Curiosity went through a “stone parking lot” and captured a panorama of the Teal Ridge and Strathdon outcrop, a rock composed of layers of wavy sediments that could have been sculpted by wind, water or both.
"We are seeing an evolution in the ancient lake environment recorded in these rocks," said Valerie Fox, co-leader of the clay campaign at the California Institute of Technology. “It was not just a static lake. It is helping us move from a simplistic view of Mars from wet to dry. Instead of a linear process, the history of water was more complicated. ”
NASA has managed to capture the strange sounds heard on Mars. Thanks to the seismometer of the Insight probe – which landed on Mars in November 2018, but it was until April that we caught its strange sounds – the vibrations of the red planet could be heard. Seismic activity can provide an inner image of a planet and how it has formed.
CNN learned in June this year that NASA's Mars Reconnaissance Orbiter captured an image of a strange mound on the Martian surface that resembles the Starfleet symbol of Star Trek, the space exploration organization, diplomacy, research , defense and maintenance of peace.
The image is a natural mound on the surface of Mars, which may have occurred due to an eruption that launched lava around sand dunes, but without covering them.
