BERLIN -- Scientists (click here) have released a brief recording of the sound that Europe's space probe Philae made when it became the first to land on a comet last week.
The two-second recording features a short, sharp thud as the lander touched down about 311 million miles (500 million kilometres) from Earth on comet 67P/Churyumov-Gerasimenko's icy surface.
Martin Knapmeyer of the German Aerospace Center, DLR, said Thursday that sound was recorded by instruments in the lander's feet....
It is not exactly the same as sand when it has movement in the wind, but, it has those 'qualities.' As if it is particles bouncing off each other and making sound. What was so astounding to me at all is that sounds exists in space. The air around the comet is not a void.
