NASA, 30 July 2020thrown in perseverance continues to take advantage of its navigator. February 18, 2021 day of the red planet The vehicle, which successfully landed on the surface, continues its studies to search for vital signs and collect samples. On his last mission, he managed to record the voice of Mars.
perseverance planetary scientist who studies data from his rover’s microphones Baptiste Chide, JPL(Jet Propulsion Laboratory) made the following explanation for the recorded sounds: From the wind gusts to the driving sounds of the rover, the entire recording is filled with the sound of Mars. Plus, it feels like you’re really standing there.
The Lucy spacecraft is in trouble! NASA is investigating
NASA is investigating the problem with the Lucy spacecraft, which it announced to have launched after a successful launch.
How do they record the sound of Mars?
France‘in Astrophysics Research Instituteworking in chide, Martian He says that the sounds have quite strong bass vibrations, so we can really feel it when you listen to it with headphones on. The future of microphones Anthem He also stated that he thinks it will contribute more than expected in research on other planets.

The company made the following statement on the subject:
Some of these records inform scientists about changes in the planet’s atmosphere; After all, sound propagates through vibrations in the air. perseveranceon the pole of SuperCam Its microphone is in an ideal position to monitor micro-turbulence changes in the air. of the rover MEDA (Mars Environmental Dynamics AnalyzerIt has a complementary structure to the special wind sensors that are part of the atmospheric vehicles package called .
MEDA‘s sensors collect information about wind speed, pressure and temperature. Every time you start your job 2 hours These sensors, which work throughout, acquire data at up to 2 samples per second. on the other hand JPL, SuperCamof per second 20 thousand He said he was able to obtain close data. However, he stated that the working time was quite short.
MEDAprincipal investigator and Spanish National Aviation and Space Technology Institutein charge of Jose Rodriguez Manfredi same JPL In his statement he said:
It’s like comparing a magnifying glass to professional microscopes that can zoom up to 100x, from the weather scientist’s point of view, every detail and context complements each other.
