National Aeronautics and Space Administration or NASA (NASA) has released one of the important information from InSight spacecraft sent to explore Mars It was discovered that Mars is moving faster every day. and this increased at a distance It could cause Mars and Earth to have the same amount of 1 day in the next few thousand years.
Currently our world and Mars have the same rotation period: One day in the world equal to 23 hours 56 minutes and One day on Mars Equal to 24 hours 37 minutes, but with new data from the InSight probe it was found that Mars rotates faster at a speed of 0.76 milliseconds per year.
On board the InSight spacecraft, there is an important instrument called RISE (RISE-Rotation and Interior Structure Experiment). By measuring nuts, which are the result of fluid movement inside the star. Data from seismic wave measurements found that the core of Mars has a radius of 1,780-1,830 kilometers, which is considered very large. It is more than half the size of Mars itself (3,390 kilometers) and has a basic density of 6.2-6.3 grams per cubic centimeter. The core of Mars was also found to be distorted and not spherical.
The RISE tool also has another type of test. Measuring Mars’ rotation rate The experiment uses NASA’s Deep Space Network to send high-intensity radio signals to Mars. An increase reflects that signal back. The fact that both Earth and Mars rotate around themselves The frequency of radio waves sent back and forth between Earth and Mars shifts due to the Doppler shift caused by the rotation of Mars. Analysis of this variable frequency helps scientists to determine the exact degree of rotation of Mars.
From experiments and data collected by the InSight spacecraft during its 900-day mission to Mars, scientists have discovered that Mars is rotating faster by 0.76 milliseconds per year. and when they are studied in detail This allows you to know the rotation speed of the star. Today, Mars takes 24 hours 37 minutes every 1 rotation
What surprised scientists is that this faster rotation, and by increasing this rate, will make the time of one day in the future the same as the time of the Earth. And although it is a small number But it surprised astronomers because they cannot explain how Mars spins faster.
As for the InSight spacecraft, it is NASA’s Mars exploration vehicle. The spacecraft landed and operated on Mars from 2018 until it ran out of power and ended its mission in December 2022, although the mission ended. But the valuable data collected by the spacecraft over four years is still useful for scientists studying the geology of Mars. The main goal is to study the internal structure of Mars.
