The Remarkable Truth About Mars' Core Unveiled by Recent Discoveries #mars #sciencefacts #short
5Researchers applied similar seismic techniques using InSight, which launched in 2018. Equipped with a seismometer called the Seismic Experiment for Interior Structure, InSight measured seismic activity and generated precise 3D models of Mars interior, including the core. During its active period, InSight detected numerous marsquakes, but it was in 2021 that things truly became fascinating. Two significant events occurred on the opposite side of Mars from InSight, a massive marsquake and a meteorite impact. These events presented a unique opportunity to analyze waves that traveled around and through Mars, providing unprecedented insights into the Martian core. By comparing the travel times of seismic waves through the core with those remaining in the mantle, researchers estimated the density and compressibility of the materials encountered. The findings were unexpected. Mars core appeared to be a squishy liquid throughout, in contrast to Earth's core, likely consisting of a liquid outer core and a solid inner core.
