In November 2018, the lander in sightfrom NASA, arrived at a destination on Martian soil with the aim of studying the earthquakes that occurred on Mars, and with their help to understand a little better planetary geology. But he could not only get data on Mars. Thank you tremor detection devicescould detect and analyze the impact of possible meteoroids (meteorites when they have already hit the ground), so it would also be possible to find out area Martian.
Since then, several such strikes have been discovered, reaching even write down how they sound. One of them happened just a year ago, but so far we have not been able to find out the details. This is stated both in a NASA statement and in a study published in Geophysical natural sciences. But the most curious thing, at least to non-specialists in astronomy, is the recording of the impact that the mission scientists released.
In it, the moment of a meteorite falling to the ground is heard as a blunderwhat it seems almost straight out of a video game. This comical sound has an explanation, as explained by NASA. This is due to the aridity of Mars, but let’s see what else these researchers explained.
Meteorite impact on Mars
InSight has various toolsaimed at drill into the soil of Mars how to analyze possible earthquakes. The latter was made possible thanks to a seismograph capable of detect shocks emanating from its bowels or from the impacts of possible alien meteoroids on the planet.
And that’s exactly what happened September 5, 2021, almost three years after the robot was installed on Mars. On this day, a shock corresponding to an external influence was detected. Mission scientists took the recording and extracted data in sight and calculated where the accident could have happened. But they still had to confirm it.
To do this, they sent to the point of their suspicions martian orbiter. This is a probe that revolves around Mars, so it could easily take pictures of the specified point. When this happened, they discovered that the impact had indeed created three new craters.
But it’s not the only meteor to hit Mars since InSight has been in touch. Total robot detected 1300 marsquakess (so-called Martian earthquake), three of which, apparently, are associated with similar impacts. They even believe that there could have been more, that strong wind noise would have hidden them. Now that you know your distinctive signatures, they hope to find some others by looking at the data from all these years. Of course, only one influence has been made public so far, which sounds so curious.
Why does it sound like this?
As explained by NASA, this sound blunder so curious about Shop Atmosphere Featuresas well as. However, on Earth, something similar could be perceived in desert zones.
This is because “after sunset, the atmosphere retains some of the heat accumulated during the day, and sound waves travel through this heated atmosphere at different speeds, depending on your frequency“.
So the bass sounds travel a little bit faster than tripled, so while someone close to the point of impact would feel clapin the place where the recording was made, this low part was in front, as a kind of blunder.
Something similar was felt when calculating the speed of sound on Mars a few months ago. Sounds of different frequencies travel at different speeds.
InSight’s latest steps
InSight more than achieved its goals despite having some initial problems with a hammer designed to break through the surface of Mars. However, his retirement is getting closer.
This is due to the recent accumulation a lot of dust on their solar panels. As a result, they cannot operate at full capacity, so it will be increasingly difficult to obtain energy. As such, there may be no other choice but to turn it off later this year. However, it has provided scientists with invaluable data about Mars. His work was fast compared to other Martian robots; but, of course, very intense.
