Our neighboring planet Mars is spinning faster on its axis and scientists aren’t quite sure what’s causing it. The US space agency NASA reported on August 7 that experts have been analyzing data from the InSight module to track the planet’s rotation speed. They found that the length of a day on the Red Planet has shortened by a fraction of a millisecond each year because the planet as a whole spins faster. The team doesn’t know exactly what is causing this acceleration, but they have a theory. They point out that it could be because Mars as a whole is changing slightly, for example in the mass of the planet or what is happening on its surface.
