Mars is Spinning Faster!
NASA's InSight mission has revealed that Mars is spinning faster, with its rotation period shortening by about 4 milliseconds per year. This subtle acceleration, tracked over several Martian years using InSight's precise radio transponder, is likely caused by the redistribution of mass within the planet, particularly its liquid core. The data suggests that Mars has a large liquid core, roughly half the planet’s total radius, with a different composition than Earth's, possibly containing lighter elements like sulfur or oxygen. This discovery also included measuring Mars' wobble, offering deeper insights into the planet's internal structure and its comparison with Earth's dynamics. These findings are crucial for understanding Mars' geological history and its potential for past habitability. #physics #science #cosmos
