Picture through NASA
The surface of Mars has been a somewhat well – known area since 1976, when NASA Viking 1 lander took the first picture of it. But now, almost 50 years after that, InSight, a descendant of Viking 1, has found information about the planet’s interior for the first time.
In context Marsista, seismic waves causes “marsquakes,” which have allowed scientists to study the internal structure of the planet since 2019. The speed and shapes of the waves depend on the materials passing through them. InSight’s seismometer, the Seismic Experiment for Interior Structure (SEIS), utilized these for its results.
Three publications were published research team Science diary, detailing the depth and composition of the planet. On paper dedicated to each of the following areas, the facts sheath, shelland nuclear was revealed, including confirmation that the center of the planet is indeed molten.
Other observations are that the shell of Mars is thinner than previously thought and may consist of sublayers. It goes to a depth of 12 miles if there are two sublayers, and 23 miles if there are three. There is then a 969-mile-deep mantle before it reaches the molten core, which extends to a radius of 1137 miles.
“This study is a once in a lifetime opportunity ” said Simon Stähler, lead author of the “core” article. “It took scientists hundreds of years to measure the Earth’s core; after Apollo operations, it took 40 years to measure the Moon’s core. InSight only took two years to measure the Martian core.”
But STOP and the team’s work doesn’t end there. STOP detects new marsquakes almost daily, and the team expects to exceed more than 4.0.
“We would still like to look big, ”says JPL’s Mark Panning, co-publisher of“ crust. ”“ We have to do a lot of careful processing to get the things you want out of this information. Doing a bigger event would make all this easier. “

I mapped the interior of Mars for the first time and found surprises:
– Bark: thinner than expected, maybe two or three lower layers
Almond: single-layered (1,560 km), simpler than the earth
– Core: larger than expected (1830 km radius) and melt pic.twitter.com/cLgQVkwBnz

For the first time, seismologists have described the interiors of another planet in addition to the earth!
