Nasa lander captures first sound of Mars wind
Nasa’s new Mars lander has captured the first sounds of the Martian wind.
The Jet Propulsion Laboratory released audio clips of the alien wind, which is estimated to be blowing between 10mph to 15mph.
The low-frequency rumblings were collected by the InSight lander during its first week of operations on Mars.
These are the first sounds from Mars that are detectable by human ears, according to the researchers.
“Reminds me of sitting outside on a windy summer afternoon ... In some sense, this is what it would sound like if you were sitting on the InSight lander on Mars,” Cornell University’ s Don Banfield told reporters.
The noise is of the wind blowing against InSight’s solar panels and the resulting vibration of the entire spacecraft.
The sounds were recorded by an air pressure sensor inside the lander that is part of a weather station, as well as the seismometer on the deck of the spacecraft.
The low frequencies are a result of Mars’ thin air density and even more so the seismometer itself.
The seismometer will be moved to the Martian surface in the coming weeks; until then, the team plans to record more wind noise.
