The measurements suggests that the radius of the Martian core is 1,810 to 1,860 kilometers, roughly half that of earth's core. That's larger than some previous estimates, meaning the core is less dense than had been predicted.
I think REDTAPE!!What tape used to make the measurements
Up until now, the only celestial bodies that have had their cores measured were Earth and the moon. To make such measurements, scientists have used seismic data from sensors that detect the sounds made by quakes. Eager to do the same for Mars, NASA sent Insight to the red planet—it landed near the planet's equator back in 2018 and began listening for Marsquakes soon thereafter. To date, sensors aboard the craft have captured seismic data for approximately 500 quakes. The researchers have found that most of the quakes are quite small compared to those on Earth, though approximately 50 of them have been between 2 and 4 magnitude—strong enough to use for measuring the planet's interior. Prior to measuring the core, data from Insight had been used to measure the depth and thickness of layers of the Martian crust.What tape used to make the measurements
So to measure Red Planet a Red Tape is usedI think REDTAPE!!
It's surprisingly large.... very informative...View attachment 22322
