NASA’s preseverance astronaut collected Second sample of Martial rocks from the surface of the Red Planet. Mission team members they announced in a tweet on Wednesday After re-drilling in the rocket rock, Persurens sealed the resulting core in a predetermined titanium tube.
This success was achieved just two days after collecting the first healthy speciman of the same stone. The first persuasion attempt was made on August 5; However, due to the porosity of the target rock, the collected sample was scattered around the drilling site on the surface of Mars. But Rasht is much harder, as was shown in the next two attempts.
The first model is named Mondenier and the second model is named Montagnac. These specimens can reveal a great deal of information about the area’s past, possibly including volcanic activity and sustainable periods of water presence.
“The first two examples seem to illustrate a life-giving environment,” said Dr. Ken Farely of Celtic, who is the project scientist on the mission. “The long-term presence of water is a very important sign.”
Rasht rock, an igneous rock Basalt which may be the result of lava flow in this area. The presence of salt crystals in igneous rocks is very useful in the radiometric sensing process. After measuring all the samples and arranging them according to time, a vision of the history of this crater and the most important events that took place in it is formed before our eyes. How to form Jizro mouth the emergence and disappearance of Lake Jizero and the Planet’s climate change in the distant past are some of these events.
Identifying Salt in these rocks may be much more exciting. These Salts may have enetered the crater with a stream of surface water and transformed the early rocks, or they may have settled on the crater surface after the water evaporated.
The Salt crystals in these two specimens may have trapped small bubbles of ancient Martian water. If so, they could, like microscopic time capsules, provide a wealth of information about the unknown of Mars’ ancient climate and the planet’s viability in the past. Salt crystals on Earth are known for their ability to preserve the signs of ancient life.
Scientist on the Presence team know that the crater was once full of water; But they are not sure how long these conditions have existed. It is possible that Lake Jizro once and for all was rapidly filled with running water and evaporated over a short period of time (for example, 50 years); But the degree of metamorphosis that scientists have observed in the sampling target rocks increases the possibility of surface water being present for a very long time.
Surface water may be associated with Lake Jizro or it may have reached rocks long after the lake dried up. Scientist believe that whether this water has excited in the crater for tens of thousands of years or millions of years, it has sufficiently created the conditions for microscopic life in the past.
The perseverance Mars rover continues to search the crater to find the right answers to our questions about Martian history. Titanium tubes containing the collected specimens are stored in the Martian chamber to be released onto the planet’s surface in several groups at the appropriate time. This reduces the chance of losing samples. The specimens will eventually be transported to Earth by a Joint mission of NASA and the European space Agency (ESA) in about a decade.
The astronaut’s next destination is probably the sandy and rocky ridges of South Seitah, 200 meters from its current location. The current specimens probably belong to the youngest geological layer of the Jizero estuary. The Southern Hemisphere is probably older, and in completing the current two examples, it will give the team of scientists a better view of the processes shaping the surface of the Jizro.
Beginning in October, all Mars missions will cease for a few weeks during the “Solar comparison” period. During this period, the Sun is placed between Earth and Mars, disrupting communications between ground stations and orbiters and astronauts. The perseverance astronaut will probably not start drilling in the Southern hemisphere until the end of this period.
