Three weeks ago , tellurian sit agog by their computers as they listen the first sounds read by NASA ’s Perseverance rover on the Martian surface . Turns out these tracks will be a regularity , as NASA just release another ballad from our fresh favorite robot .
Last week , we get word Perseverancezapping rock with a optical maser . Ok , so not all the audio recordings are going to be that coolheaded . The latest fall is a scrap more … squealing .
If that ’s a scrap foresighted for you , NASA was also kind enough to release a 90 - second highlighting spool from the private road , which you may represent here :

Perseverance has an immensely busy schedule during its two - twelvemonth turn of the Red Planet . As it skitters around Jezero Crater research for signs of ancient life , the robot is spring to make some noise . But for most of humankind ’s history on the Red Planet , science ’s forward slog has been a tacit experience ; we ’ve beheld photo of the quiet genus Sepia sky and the lonely cherry-red sand dune , but never have we heard the grunge grind under a rover ’s bike and or the metal clanking of its drive .
No longer . Perseverance ’s microphones are sum a whole newfangled attribute to our experience of Mars . The microphone that made the late transcription was in the beginning reckon to memorialise the rover ’s entry , descent , and landing , but it ended up only becoming operating after landing .

“ A lot of people , when they see the image , do n’t appreciate that the bike are metal , ” Vandi Verma , a elderly engine driver and rover driver at NASA ’s Jet Propulsion Laboratory in Southern California , said in an agencypress release . “ When you ’re drive with these wheels on rock , it ’s in reality very noisy . ”
Last week , Perseverance took a 90 - metrical unit drive across the satellite , one of its first tentative forays as NASA continues to check the rover ’s systems follow its striking arrival on Mars a calendar month ago .
“ If I heard these sound driving my car , I ’d pull over and call for a tow , ” pronounce Dave Gruel , lead engineer for Mars 2020 ’s EDL Camera and Microphone subsystem , in the NASA release . “ But if you take a moment to consider what you ’re hearing and where it was immortalise , it makes perfect sense . ”
The Martian soundtrack is replete with what you ’d expect from an alien human beings . A bizarre , high - pitched frequency penetrate the audio ; NASA ’s still seek to draw a drop on what ’s causing it , though they distrust it may be electromagnetic interference or something to do with how the rover ’s mobility organisation interact with Mars ’ surface .
To this writer , it sounds something like an empty vegetable oil drum revolve down a gentle hill . palpate barren to comment with your own picture , though . nail on a ruby chalkboard ?
