Scientists have only ‘seen’ inside Mars. Here is what he found
The researchers found the core density to be surprisingly low, at just 6 grams per cubic centimeter, much lower than they had hoped for an iron-rich center. “It’s still a mystery how the cover is so light. There should be light elements, even though what it could be is unclear. It’s up to him and his team to figure it all out,” Stahler said. It is hoped to detect the P-waves generated by the planet-generated Marsock from where Insight stands, as they can pierce through the core mantle boundary, so they can pass information about the structure of the core to the recipient of the lander. But for that to happen, Stahler says, “Mars has to play together and we have to give this earthquake to the other side of the planet.”
In Stellar’s team article, they report a basic radius of 1,830 km. Another team, led by ETH Zyorak geophysicist Aamir Khan, found that the size was so large that it left a small space like the Earth’s bottom, which surrounds this layer. Works as a heat trap blanket. The Earth’s crust is divided into two parts, with a so-called transition zone between them. The upper and lower surfaces contain different minerals. “Tuesday’s veil is – I can easily say – it’s just a slightly simpler version of the Earth’s mantle, in terms of minerals,” says Khan.
Previous estimates of core radius using geochemical and geophysical data indicate the absence of a lower venue, but scientists needed insight seismological readings to confirm this. Without this layer, the Martian core would have cooled more easily than the ground. This is key to understanding the evolution of the Red Planet, and in particular why it lost its magnetic field, an obstacle that would have saved the atmosphere and potential life from severe solar winds. The formation of a magnetic field requires a temperature gradient between the outer and inner center, which is so high as to form a current of rotation that dissolves the liquid in the core and creates a magnetic field. ۔ But the cover cooled so fast that the vehicles ran out.
Khan’s analysis also shows that Mars has a thick lithosphere, the hard and cold part of the mantle. This may be an indication of why the red planet does not have the plate tectonics that are the crater of volcanoes on Earth. “If you have a very thick lithosphere, it would be very difficult to break it down and create an exact equation of plate tectonics on Earth,” says Khan. “It may have started very soon on Mars, but it’s definitely stopped now.”
While on-site vibrations on Mars’ internal vibrations, Everestrips, in search of symbols of ancient life in the persistence rocks, is tilting from its place, pulling out places to collect regular specimens, and learning about the geological history of Gezro. ۔ “It’s not a research sprint, it’s a marathon,” said Thomas Zarbochen, NASA’s associate administrator of science, who opened a press conference Wednesday to highlight progress in the rover’s first few months in its new home. Added Steadfastness is a step in the long legacy of Mars exploration that combines the search for robotics and humans for the future.
In a press briefing, the scientists said that so far it has been steadfast on its road trip. “The challenge is figuring out where we want to go and how we’re fitting everything into our schedule,” said Vivien Sun, systems engineer at NASA’s Jet Propulsion Laboratory. The rock has decided to excavate its first reef samples about 3,000 feet south of the rock, which will be stored in the rover’s belly and later tied to the surface of the planet for future return missions that will land them. Will take up.
