CAPE CANAVERAL, Florida (AP) – NASA's new Mars Lander has picked up the first notes of the "truly alien" Mars Wind.
The Jet Propulsion Laboratory released alien wind audio clips on Friday. The low-frequency rumble was collected by the InSight lander during its first mission week on Mars.
It is estimated that the wind blows 10 miles per hour to 15 miles per hour (16 km / h to 24 km / h). According to the researchers, these are the first sounds from Mars that can be perceived by human ears.
"Reminding me to sit outside on a windy summer afternoon … In a sense, it would sound like you were sitting on Mars in the InSight Lander," Don Banfield told Cornell University to reporters.
The scientists involved in the project agree that the sound has a different quality.
Thomas Pike of Imperial College London said the rumble was "slightly different" to anything we experienced on Earth, and I think it gives us another way to think about how far we can get those signals.
The noise is the wind blowing against the InSight solar panels and the resulting vibrations of the entire spacecraft. The sounds were recorded with an air pressure sensor in the lander, which is part of a weather station, and with the seismometer on the deck of the spacecraft.
The low frequencies are a result of the low air density of Mars and even more the seismometer itself ̵
The Viking Landers of Mars in 1976 picked up the spacecraft shake caused by the wind, but it would be a stretch to keep it healthy, said InSight senior scientist Bruce Banerdt of JPL in Pasadena, California ,
InSight's "truly alien" sounds have been portrayed by Banerdt as "being on a planet that in some ways resembles Earth, but in a sense is truly alien."
InSight landed on Mars on November 26th.
"We're all on a high of landing last week … and here we are less than two weeks after landing, and we already have amazing new insights," said NASA's Lori Glaze, vice president Director of planetary science. "It's cool, it's fun."
