Mars' Mysterious Accelerated Rotation: Insights from NASA's InSight

Scientists analyzing data from NASA's InSight Mars lander have discovered that Mars is rotating faster, with its rotational speed increasing by approximately four milliarcseconds per year squared. The measurements, made using InSight's Rotation and Interior Structure Experiment (RISE) instrument, also revealed the planet's wobbling motion caused by its molten metal core. The data allowed scientists to estimate the size of Mars' core and revealed regions of slightly higher or lower density buried deep within the mantle. The findings provide valuable insights into Mars' rotation, core, and other planetary characteristics, contributing to groundbreaking discoveries in planetary science.
