Sensors in the feet of Rosettaâ€™s lander Philae have recorded the sound of touchdown as it first came into contact with Comet 67P/Churyumov-Gerasimenko. The instrument, SESAME-CASSE, was turned on during the descent and clearly registered the first touchdown as Philae came into contact with the comet, in the form of vibrations detected in the soles of the landerâ€™s feet.
Technical note: This is the actual sound file; i.e. it is a recording of mechanical vibrations at acoustic frequencies. No modification was necessary except for some technical adjustments (e.g. the .wav format requires amplitude normalization). Actual frequency content and duration are unchanged.
