CAPE CANAVERAL, Fla. — It's the sounds of Mars. 

NASA's InSight lander touched down on Mars 10 days ago, and has already sent its first pictures. But this is the first time we've ever heard what Mars sounds like. 

  • InSight unexpectedly picked up vibrations caused by wind on Mars
  • The wind was blowing 10 to 15 mph

InSight sensors captured the low rumble caused by vibrations from the wind on December 1, NASA said. The wind was estimated to be blowing 10 to 15 mph from northwest to southeast, which matched the direction of dust devil streaks observed from another NASA spacecraft in orbit. 

InSight's seismometer and another sensor picked up the noise, and it was not planned. The seismometer is waiting to be deployed to the lander's robotic arm, and once that happens it will be covered with a domed shield to protect it from wind and temperature changes, so it won't be able to pick up this sound. 

InSight landed on Mars on November 26. It's main mission is to study the interior of the planet.
