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 the InSight Lander on Mars, "Don Banfield of Cornell University told reporters ,
The scientists involved in the project agree that the sound has a slightly different world. Thomas Pike of Imperial College London said the rumble was "something other than anything we experienced on Earth, and I think it just gives us another way to think about how far we can get those signals" (1
The low frequencies are a result of the low air density of Mars and even more the seismometer itself – it is to detect subterranean seismic waves well below the threshold of human hearing. The seismometer will be moved to the surface of Mars in the next few weeks. Until then, the team plans to record more wind noise.
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 now have Banerdt recordings "on a planet that is somehow similar to Earth, but in some ways truly alien". InSight landed on Mars on November 11th. 26.
"We're all still on a high from landing last week … and here we are less than two weeks after landing, and we already have some amazing new insights," Lori Glaze told NASA. Deputy Director of Planetary Science. "It's cool, it's fun."
