NASA’s InSight Just Heard Wind on Mars. You Can Hear it Here!

InSight is designed 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

NASA Recorded the Sounds of Mars (And It's Almost All Creepy Bass)

You can hear more of the sounds here and listen to NASA's news telecon with a panel of scientists here.

We know what Mars looks like, but there's a lot of mystery around what Mars sounds like.

The raw recording is a low pitched, barely audible purr. The ground had to be as flat as possible and the lander needed a bit of luck to avoid any large rocks that could have hampered its ability to work with its instruments. Instead, they're specially created to tackle an important scientific challenge: solving mysteries about the interior of Mars. The seismometer will be moved to the Martian surface in the coming weeks; until then, the team plans to record more wind noise. In the near future, InSight will place the seismometer tool used to detect the vibrations on the planet's surface.

"Capturing this audio was an unplanned treat", said InSight principal investigator, Bruce Banerdt. The low-frequency rumblings were collected by the InSight lander during its first week of operations at Mars.

"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. The air pressure sensor recorded the vibrations directly from changes in the air. The seismometer recorded lander vibrations caused by the wind moving over the spacecraft's solar panels, which are each 7 feet (2.2 meters) in diameter and stick out from the sides of the lander like a giant pair of ears.

Tyler Perry pays off $400K worth of layaways
The number of layaways Perry took care of is unknown, but a store manager at the Douglasville location told the AJC that the store typically has over 1,000 layaways during the holidays.

"Humans are multisensor people, and now we have two of our sensors turned on with this mission", with both audio and visual data streaming back to Earth, Don Banfield, the science lead for the air pressure sensor, said during the news conference. The lander's sensors indicate the winds were blowing at speeds of 10 to 15 miles per hour.

"It's a little like a flag waving in the wind", he added.

But the scientists warned not to get too attached to these recordings, because they won't last long.

The craft's landing comes as part of NASA's mission to explore the planet's deep interior. The two instruments recorded the wind noise in different ways. "It's going to become very hard to hear the sounds from the outside of Mars later on". The vehicle arrived on Mars in November, successfully landing after months of travel to the Red Planet. "We are really going to have an opportunity to understand the processes that control the early planetary formation".
