The american InSight probe and its SEIS French seismometer recorded the sound of the wind processing on the surface of the superior planet. A first.
It's a world initial. If photos of Mars have already been sent to Earth by exploration missions, like the mechanism Curiosity, we tend to had to date no plan of the sound atmosphere on the surface of the superior planet. The yankee InSight probe and also the SEIS French seismometer have simply remedied it. Indeed, still on the deck of the lander, the instrument designed at the Institute of Earth Physics in Paris recorded the sound of wind processing within the plain Elysium Planitia wherever InSight landed on Nov twenty sixth .

"This recording of the InSight vibrations, caused by the wind of Mars, due to SEIS, shows the good sensitivity of our instrument to any movement. Certainly, for now, we tend to don't hear the within of Mars however simply the movements of its atmosphere. and that we ar excited to contribute to the present world premiere! same Philippe Laudet, SEIS project manager at Cnes.
The vibrations made by processing on the lander ar of explicit interest to the seismometer team. Their data is crucial for the remainder of the mission so as to research the measurements that the device can build on the bottom, once it's been deposited by the mechanical arm of InSight. A planned readying around Christmas. "This noise has nothing to try and do with the characterization of the seismal noise of the LG to settle on the quietest web site for the readying of SEIS, that we are going to verify within the days to come", however, processed Philippe Lognonné , the daddy and scientific leader of SEIS.
For its half, the LG conjointly recorded the sound of the wind via its meteorological observation post APSS. On the day of the recording, on Gregorian calendar month first, the 2 instruments indicate that the wind was between five and seven kilometers AN hour. In detail, what they recorded is but slightly completely different. SEIS offers United States to listen to the vibrations of the frame, caused by the wind moving higher than the star panels, through British high frequency sensors integrated into the instrument. As for APSS, it's its air pressure sensing element that directly recorded the vibrations of the air. Anyway, they are available along to supply the primary natural audio recording of Mars!
