Here's how the wind plays on Mars – BGR


One of the nicest things about the new NASA InSight lander that has recently arrived on Mars is that it will be able to hear the sounds generated in depth closely. It has the potential to teach us a lot about how Mars works. Before this happens, NASA must prepare the robot to start using its powerful tools. and in doing so, the Jet Propulsion Laboratory effectively captured the sounds of the wind that whipped the dusty Martian surface.

In a new video, JPL explains that the InSight integrated seismometer has begun to detect vibrations. In the end, the team determined that the vibrations were the result of the wind striking the solar panel matrix of the robot and causing it to shake. NASA has recorded the vibrations and now you can listen to them yourself.

As the video explains, the pitch of the sound is extremely low and can hardly be heard unless you have the headphones and the volume turned up. A filter that raises the pitch of two octaves makes listening much easier.

The result is a recording that sounds a bit like what you would feel if you cupped your hands in a lively wind.

But NASA did not stop here. A separate instrument that measures air pressure recorded the same bursts and sent them back to Earth. The video also includes that recording, which is accelerated and filtered so that it is easier to listen to.

It's nice to hear the wind coming from another planet, even if it sounds exactly like the wind here on Earth. It is also a great demonstration of InSight's capabilities and a demonstration of how powerful and sensitive its instruments are. In the near future, JPL will instruct the robot to deploy its sensors to the ground around its base and at that moment real fun will begin.
