Like slicing a wounded peach and showing a huge yellow hole, Mars Share the mystery of the inside of the alien planet with the first ever map of it — released as part of three new studies published in the journal on July 22nd. Science..
This premier look inside Mars is the culmination of two years of research (and decades of planning) by NASA’s InSight lander. This is a static science robot deployed on Mars in 2018 with the sole mission of studying the invisible interior of the Red Planet. Approximately a month after landing on a flat, smooth plain known as the Elysium Planitia, InSight used a robotic arm to install a small seismograph on the surface of nearby Mars. Mars — Seismic vibrations on the planet, Earth..

“Unlike Earth, Mars doesn’t have a tectonic plate. Its crust is like one giant plate instead,” says NASA researchers. Written in the statement.. “But faults, or rock crushing, are still formed in the crust of Mars due to the stress caused by the slight contraction of the planet as it continues to cool.”
These ruptures can cause seismic vibrations — and in the last two years, InSight has detected 733 of them. NASA researchers use 35 of the largest Mars (between magnitudes 3.0 and 4.0, respectively) to calculate how fast and how much seismic waves are moving around the Earth and map their internal structure. I made it possible.
The team discovered that, like Earth, the interior of Mars is made up of three layers: the crust, the mantle, and the core, but the size and composition of these layers are quite different in the two worlds. For example, the crust of Mars is much thinner than researchers expected, 12-23 miles (20-37 km) deep, and contains two or three sublayers (for comparison, The Earth’s crust extends to a maximum depth of about 62 miles, or 100 km, According to the USGS).
Below the crust is a considerable mantle, extending about 969 miles (1,560 km) below the surface of Mars, followed by a huge core that begins approximately halfway between the surface and the center of the planet. The core (melted like the Earth’s outer core) was larger and more liquid than researchers expected.
Scientists still don’t know if Mars contains a solid inner core like Earth, but researchers say it’s amazing to measure the outer core of the planet after just a few years of research. It is a result.
“It took scientists hundreds of years to measure the Earth’s core,” Simon Stähler, the lead author of one of the new papers and a professor of earth sciences at the Swiss research university ETH Zurich, said in a statement. It was. “It took 40 years to measure the lunar core after the Apollo program. InSight took only two years to measure the Martian core.”
