NASA’s audio recording of meteorites hitting Mars sounds more like a pebble hitting water than an impact.

if you like movies armageddon either Deep Impact Asteroids and meteors hitting the planet are believed to cause catastrophic destruction that would end all life on the planet. But meteors break into our atmosphere all the time, and we are not the only planets that experience this phenomenon. as reported by futurism, NASA recently released an audio clip of meteorites hitting Mars and forming multiple craters, and the impact isn’t catastrophic; It sounds like dropping a pebble into the water (you can listen above).
In 2018, NASA sent the Mars InSight lander to Mars to measure (it would not be fair to call it an earthquake), which it has done for the past four years. But what the sensitive seismometer caught instead was something that had never been caught before, the impact of four meteorites on the surface of Mars. While you might imagine some deafening explosions and perhaps still or silence after the instrument is destroyed, instead, you hear something heavy, like bubbles under water.
According to an educational video describing a never-before-heard phenomenon, the bleep sound rather than the blast sound is an effect caused by the environment that allows bass sounds to travel faster than high-pitched sounds. In the sound clip, you can hear the meteorites enter the atmosphere, break up into at least three pieces, and then all three of them impact the ground. While it may sound surprising to us and even a little intimidating to think of something like this here, it’s a run-of-the-mill day on Mars.
A new study has shown that the Red Planet is hit by space rocks more than previously thought, as it determined that such asteroids hit Mars 200 times a year. While these are typically about three to six feet wide and do not cause nearly the kind of damage that science fiction portrays, they are often such that they can significantly alter the surface. Earth is not untouched by this phenomenon, but our atmosphere breaks them up, while the thin atmosphere of Mars does little to stop them.
After impact, NASA’s Mars orbiter used its HiRISE and reference cameras to obtain position over the impact area and capture images. What they found were three impact craters, leading them to conclude that the meteor broke into at least three pieces and slammed into the surface. Although these were the first impacts discovered by NASA scientists, they have led to many more discoveries, giving an idea of the history and internal structure of Mars.
This is a landmark moment in the study of our nearest neighbour, and there is much to be learned from tiny bits of data. Of course, if Elon Musk plans to take humans to Mars at some point, he’ll have to figure out a solution to the meteor problem. Imagine driving to work and getting hit by a six-foot cliff falling from the sky. The more we think about it, the Earth seems like a wonderful place to live.
