InSight isn't exactly a recording studio on Mars, but an air pressure sensor inside the lander and a seismometer on the lander's deck were both able to pick up wind vibrations.
The audio was captured by two different pieces of state of the art, hyper sensitive recording equipment aboard the lander. An internal air pressure sensor whose job it is to collect meteorological data, recorded the air vibrations directly.More news: Jennifer Aniston Opens Up About Her Marriages & Having Children!
The 1976 Viking landers on Mars picked up spacecraft shaking caused by wind, but it would be a stretch to consider it sound, said InSight's lead scientist, Bruce Banerdt, of JPL. Scientists noted that the first sounds from Mars that are detectable by human ears. NASA's Mars Polar Lander was carrying a microphone when it crashed into Mars in 1999.
"The arm will use its Instrument Deployment Camera, located on its elbow, to take photos of the terrain in front of the lander", NASA writes.
It's been less than two weeks since InSight touched down on the surface of the Red Planet, but it is already sending back awesome things for us to marvel at.
InSight is created to study the interior of Mars like never before, using seismology instruments to detect quakes and a self-hammering mole to measure heat escape from the planet's crust.More news: Israel Tells Lebanon, U.N. Peacekeepers to Destroy Attack Tunnel
"To me, the sounds are really unworldly", Banerdt said. It's like InSight is cupping its ears and hearing the Mars wind beating on it.
What's even more exciting about InSight's fascinating discovery is that the NASA team were not even planning on capturing the previously unheard wind. The robot has a lot of work ahead of it, but things always start slowly when you're handling a machine remotely from another planet.
The low-frequency sound resembles a "haunting low rumble", Nasa said.
We've never before been able to HEAR the sounds of the wind on Mars, though. Wow!More news: Trump Jr. Trolls Alexandria Ocasio-Cortez on Instagram
