One month ago Perseverancelanded on Mars , and it has already started search Jezero Crater . Among its telling suite of instruments , the NASA rover is equipped with mike and has delivered to us thefirst memorialise phone of Mars . The space way has now free some young sounds .
persistence is heard clangor , whirring , and squeaking as the six metal wheels go over rock . The rover drove for about 27.3 meters ( 90 feet ) on March 7 , which was the 16thMartian twenty-four hour period Perseverance has spent on the Red Planet ( Sol 16 ) .
“ A great deal of people , when they see the persona , do n’t appreciate that the wheel are metal . When you ’re driving with these bicycle on stone , it ’s actually very noisy , ” Vandi Verma , a senior engineer and rover driver at NASA ’s Jet Propulsion Laboratory , said in astatement . “ The variations between Earth and Mars – we have a feeling for that visually , but sound is a whole different dimension : to see the differences between Earth and Mars , and have that environment more closely . ”
The audio recording was memorialize by Perseverance ’s entering , stemma , and landing ( EDL ) mike . This is an off - the - ledge while of equipment that was added to give another sensorial experience to the landing of the space vehicle , and it is now being used to enchant the sounds of the surface and of the rover ’s natural action .
NASA has released two recordings . One is 85 second long with the highlights of the drive – this one has been edit out to filter out some of the disturbance . If this is not enough for you , you may savor in the full 16 minutes and 21 seconds of the variant that is completely raw and unfiltered .
“ If I heard these sounds repulse my car , I ’d draw in over and call for a towage , ” explained Dave Gruel , extend engine driver for Mars 2020 ’s EDL Camera and Microphone subsystem . “ But if you take a minute to consider what you ’re get wind and where it was recorded , it make complete sense . ”
And while most of the noises are what we expect from the move of the wheels and suspension on the rough terrain , the high up - lurch scratching noise is ill-defined . The engineering team is actually evaluating if it is electromagnetic interference from an electric box , or mayhap something else related to the motion of Perseverance .
The bird of passage has been very busy over the last 28 days . Perseverance has sent back the sound of itsSuperCam kindle lasers , prove its robotic limb , and performed some weather observations ( including spotting its firstdust devil ) . It has also establish a suitable place for Ingenuity , the Martian helicopter , which will presently attempt its five test flights .
