NASA's In Sight Mars Lander Captured Bizarre Sounds On The Red Planet

NASA's InSight lander on Mars has captured the low rumble of marsquakes and a symphony of other otherworldly sounds.

With SEIS, we're getting our first data on seismic activity on Mars, but the sensitivity of the monitor also allows us to record the sounds of Mars.

NASA states that scientists would further analyze how these seismic waves of quakes move through the planet's interior, which would further help reveal the deep inner structure of Mars for the first time.

The Insight team has noticed that, particularly at night, the instrument picks up odd sounds that they refer to as "dinks and donks", according to the statement.

The lander's Seismic Experiment for Interior Structure sensor has detected more than 100 events since the rover placed it on the Martian surface in January.

The May 22 quake is about a magnitude 3.7 and the July 25 quake is about a magnitude 3.3.

Jagmeet Singh told to ‘cut off’ turban while campaigning in Montreal
The encounter between NDP leader Jagmeet Singh , a practising Sikh, and a man in Montreal was captured by media. When the man tried to speak again saying 'Yeah, yeah, but...', Singh cut him off and said: 'I don't agree, sir'.

Wearing headphones is suggested while listening to these audio clips.

In one of the sound samples, a odd whistling can also be heard. NASA's Jet Propulsion Laboratory (JPL) has released a copy of those sounds, recorded on Mars earlier this year. On Earth, cracks in the crust are filled by minerals from flowing water, so vibrations from quakes pass through the material smoothly. Sound waves are then passed through fractures uninterrupted. Mars, with its cratered surface, is slightly more moon-like, with seismic waves ringing for a minute or so, whereas quakes on Earth can come and go in seconds. This seismometer can also pick up vibrations that are as subtle as a breeze. It is created to dig under the Martian surface to measure heat flowing out of the planet.

NASA's Mars InSight lander has had its ear to the ground since it arrived on the planet in November 2018.

"You're imagining what's really happening on Mars as InSight sits on the open landscape", said Constantinos Charalambous, an InSight science team member at Imperial College London.

Evening is also when peculiar sounds that the InSight team has nicknamed "dinks and donks" become more prevalent. Now, a recording from March of this year includes the sound of wind, InSight's robotic arm moving, and subtle clicking as parts inside the seismometer shift.

Listen for these dinks and donks in the set of sounds, below, recorded just after sundown on July 16, 2019.
