ORIGINAL Citation (Oct 2014): Rosetta’s Plasma Consortium (RPC) has uncovered a mysterious ‘song’ that Comet 67P/Churyumov-Gerasimenko is singing into space. The comet seems to be emitting a ‘song’ in the form of oscillations in the magnetic field in the comet’s environment. It is being sung at 40-50 millihertz, far below human hearing, which typically picks up sound between 20 Hz and 20 kHz. To make the music audible to the human ear, the frequencies have been increased in this recording. This sonification of the RPC-Mag data was compiled by German composer Manuel Senfft (www.tagirijus.de).  Read full details in ESA's Rosetta blog: http://wp.me/p46DHN-Li

A Singing Comet

Sensors in the feet of Rosetta’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 lander’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.

Philae touchdown makes a thud

Ever wonder how the International Space Station alarms sounds? This emergency alert is the last thing astronauts on the ISS ever want to hear as they work 400 km above Earth in the vacuum of space.   
 
This sound was sent to us by the Columbus Control Centre, near München, Germany, the operations centre for ESA astronauts and the Columbus laboratory, part of the orbiting weightless research centre.

The alarm is sounded on the International Space Station to alert astronauts to life-threatening emergencies such as loss of pressure or fire. The astronauts would immediately convene near their Soyuz spacecraft that serve as lifeboats, but these kind of emergencies are extremely rare and the alarm has sounded only a handful of times despite the Space Station having been inhabited since 2000. 

Most astronauts on a six-month space flight will only ever hear the sound during a practice session.

Regular 'fire-drills' are performed to make sure that even in a worst-case scenario everybody knows what to do. Mission controllers from the international partners that run the Space Station in Russia, USA, Europe and Japan re-enact scenarios with the astronauts in space. In critical situations the teams on ground need to communicate efficiently, act quickly and coordinate a solution between each other and the astronauts flying 400 km above them.
