Mars earthquakes are not the same as earthquakes, surprising NASA – BGR

NASA’s Mars InSight probe provided NASA with some interesting insights into how the red planet works. One of the most surprising things is that earthquakes act much differently than earthquakes, and scientists have no idea why this is. Mars is also very noisy, at least from a geological perspective, with a lot of noise coming out regularly.

NASA’s Mars Insight probe has been sent to the Red Planet to provide scientists with some craft ideas about the inner workings of the planet. This includes listening to earthquakes and using vibrations to create a clearer picture of what lies deep in the surface. Sure, it had some issues with the self-drilling “Mole” tool, but aside from that, it performed well.

In a new blog post, NASA’s Jet Propulsion Laboratory explains the top three things Space Agency scientists learned from Mission Insight. All of them are important, of course, but perhaps the most interesting thing to science enthusiasts like me (and maybe you) is that earthquakes differ from earthquakes in a different way.

The JPL trio of the most important things I learned from InSight starts with the fact that “muttering is the norm.” The planet appears to have a habit of producing regular and faint earthquakes, but larger vibrations are rare. In fact, the probe was unable to detect an earthquake greater than 3.7 magnitude, which is fairly moderate by Earth’s standards.

Moreover, the actual detection of earthquakes has proven difficult during the planet’s windy season. The sensors InSight uses to listen to earthquakes are shielded from the elements, but winds on Mars are so intense that they cause vibrations on Earth, masking the light earthquakes that the probe has been monitoring regularly.

The third and most interesting thing is that earthquakes on Mars are losing a vital component. Earthquakes have three parts. As NASA explains, there are two sets of “body waves” that roll through the bowels of the planet deep under our feet, then surface waves roll along the crust. NASA hopes that surface waves from the swamps will provide a picture of the planet’s internal structure, and may extend as far as 250 miles.

Unfortunately, this was not the case. In fact, of the hundreds of earthquakes detected on Mars by InSight, none produced a surface wave, and scientists struggle to explain this strange fact.

“It is not entirely unknown that earthquakes will occur without surface waves, but it was a surprise,” Mark Banning, Mission Leader, Insight said in a statement. “For example, you cannot see surface waves on the moon. But this is because the moon is scattered much more than Mars.”

But what’s the deal with Mars? NASA suggests that it is possible that “the lack of surface waves on the surface of Mars may be related to a widespread rift at the top 6 miles (10 kilometers) below InSight. This may also mean that the earthquakes detected by InSight are coming from deep within the planet, because those are Earthquakes will not produce strong surface waves. “

The jury is still outside the scope of the research, but the finding is interesting, and future research could help clarify this strange mystery.
