Sounds on Mars

[chekhonte]

The Perseverance will is equipped with two microphones and will be recording and sharing the sounds on mars.

Mars has an exceptionally thin atmosphere. I assumed this would mean that the sounds would be high pitched but so far the only released sound is of the Martian wind which is a very low rumble.

I know that this isn't much but I'll try and keep this thread updated as more sounds are released. It might be a different but fun way to use our headphone setups.

The idea to start a thread with sounds on Mars was great, really. Since you aim to keep it updated, I think it's time to add SuperCam sounds here, isn't it? I'm sure I'll check this thread every day.

Martians must be asleep. No traffic noise, radio or music from the neighbors. Just a simple wind noise.

Some new pieces of news came from NASA and the Perseverance rover mission. NASA is about to use Ingenuity, which has spent $ 80 million in development, to explore areas that a six-wheeled rover cannot reach, as well as to create 3D maps of the planet’s surface and solve other scientific problems. The purpose of the rover’s mission is to try to find traces of possible existence in the distant past of life on Mars.

Also, it would be fair to mention another Mars rover mission which must be launched next year. The mission known as the ‘Rosalind Franklin’ mission will attempt to search for life on Mars and explore martian surface. More detailed information about this mission you may find here

I'd like to hear what a drive by sounds like...

Some more interesting news from the Perseverance rover. The rover attempted to make historic acheavement this week on Friday and collect its first sample of the red planet, but data returned to Earth by Perseverance showed that no rock was collected during its attempt.

Ever wonder how you would sound on Mars? Grab your headset, turn up the volume and listen for the subtle differences between the sounds on Earth versus how they would sound on the Red Planet. Then, try the Mars Playlist to hear actual recordings from the Red Planet, as captured by the two microphones onboard the Mars Perseverance rover.

Sound propagation in a gas is a little counterintuitive. The standard formula for an ideal gas is given at http://hyperphysics.phy-astr.gsu.edu/hbase/Sound/souspe3.html. Interestingly, it only depends on the temperature and the type of molecules in the gas (CO2 on Mars), there isn't an explicit dependence on pressure. I think that formula breaks down if the wavelength=(speed of sound/frequency) becomes comparable to the distance between molecules. For example, there is a popular lab demonstration which has an old-fashioned electric bell in a glass chamber . (https://lecdem.physics.umd.edu/h/h1/h1-04.html) When the air is pumped out of the chamber, the volume diminishes and goes away. This isn't because the air is removed--plenty of air remains with a simple vacuum pump--but because the bell is shaped the way it is to match the acoustic impedance of a metal to the acoustic impedance of the air. When you pump the air out, you mess up the impedance matching.
