Photographed on Mars a “door”
Written by aquitodovale

NASA’s Curiosity rover took a photograph of Mars which aroused the curiosity of passionate movements of astronomy. In fact, his Mastcam photographed on the surface of the red planet, in the area of ​​Mount Sharp, what looks like a rectangular door that could lead to an underground level. Immediately the conspirators began to say that it is tangible proof that there is life, obviously alien, on Mars. The reason why this alien civilization is not visible would be explained precisely by that door: it lives underground. It would certainly be fascinating as an idea, but it doesn’t seem that true. In fact, it would not be a door, but a small crack in the rock that has been zoomed in a lot. This is what a spokesperson for NASA’s Jet propulsion laboratory said on Snopes.com, a fact-checking site. The slot in question would also be small: about 30 x 45 centimeters. The spokesperson explained that “There are linear fractures throughout this outcrop, and this is a place where several intersect.”

It’s not a door, that’s what it is

According to Ashwin Vasavada, project scientist in the Mars Science Laboratory, at the Gizmodo site, the one immortalized would therefore only be the space between two fractures in a rock. The expert also went on to specify that the area crossed was formed by ancient sand dunes, and that these dunes hardened over time, creating the sandstone outcrops in which the Curiosity rover is passing these days. Over time, the sandstone was subjected to variable pressure, and this led to the creation of crevasses and fractures. Vasavada pointed out that the fractures seen in this area are usually vertical. Referring to the ‘brings’ believes it is “Due to two vertical fractures, with the central piece having disappeared; or to a single vertical fracture in which the blocks have moved apart over time “. In short, it would not be a door, much less certain proof of the existence of alien life on Mars.

In August 2012, the Curiosity rover landed in the Gale crater, and then traveled over 27 kilometers in more than 3,400 Martian days or ‘sol’. Sol is used to indicate the duration of the Martian solar day, that is the duration of the day-night cycle, or 24 hours 39 minutes and 35.244 seconds, against 24 Earth hours. The photo of the door was taken in the 3,466th sol. Last March the curiosity of astronomy and science fiction enthusiasts was aroused by the ‘flower of Mars’, which was nothing more than a rock formation.

Was there water on the red planet?

Beyond the door or the flower, mankind is still making strides in knowledge of the red planet. In fact, Chinese scientists have discovered that there is further evidence relating to the past presence of water on Mars, and also of hydrated minerals that could be used during the next manned Martian missions. The study, which was published in the journal Science Advances, reported that a large basin on Mars, most likely caused by the impact of a celestial body, contained liquid water during the Amazon era. We are talking about the most recent geological era on the planet. The research in question also revealed that there are currently significant water reserves on Mars in the form of hydrated minerals and possibly frozen soil. Researchers from the Chinese Academy of Sciences National Space Science Center team used data collected by the Chinese Martian rover Zhurong on the sedimentary and mineral features of Southern Utopia Planitia, which is a vast plain located in the planet’s northern hemisphere.

The strong earthquake on Mars

The strongest earthquake ever recorded on a planet other than Earth was detected on May 4 by NASA’s Insight probe. It was an earthquake that reached magnitude 5, higher than the previous one that was recorded on August 25, 2021 again on Mars, of magnitude 4.2. In three and a half years i earthquakes it would have been more than 1,300. It remains to be defined the location and the mechanism at the origin of the quake, considered almost of maximum value, if we consider that it occurred on Mars. The mission of the Insight probe was supposed to last two years, but was then extended until December 2022. However, it could end sooner due to the dust that is accumulating on the lander’s solar panels that is putting the charging of the batteries at risk. NASA is studying the problem and will hold a press conference on May 17 to clarify the matter.
