outerspace sonifications

Sample

The joint ESA/Jaxa BepiColombo mission flew past Mercury for the first time on 1 October 2021, capturing data with the magnetometer onboard ESA’s Mercury Planetary Orbiter. A sonification of the magnetic field data is presented here.  
 
Two synthesizers can be heard, which are controlled by three characteristics of the magnetic field. The first synthesizer's pitch represents the slowly changing magnitude of the background magnetic field. First the solar wind is heard, then the increase and decrease of the planetary magnetic field, and then the solar wind again. The lower the pitch, the more intense the magnetic field. 
 
The pitch of the second synthesizer is controlled by the variations of the magnetic field magnitude. A more turbulent magnetic field is represented by a faster change in pitch. The magnetosheath crossing after closest approach is very prominent. 
 
Using the amplitude envelope as a control for the volume of the second synthesizer emphasises the different magnetospheric regions.

Sound of the solar wind at Mercury

alvedon — our last goodbye

Listen to the eerie sound of a boom on board ESA’s Jupiter Icy Moons Explorer (Juice) spacecraft deploying in space during commissioning of the spacecraft in May 2023.

 

Tip: use headphones or surround speakers for the best experience – the forward and backward wobbles of the boom come through the left and right channels.

 

The vibration signal used to create the sound came from the accelerometer on board the main body of the spacecraft, which was switched on to monitor the reaction of the spacecraft to the boom’s deployment.

 

The larger the vibration measured by the accelerometer, the louder the sound in the sonification. We can imagine the boom like a human arm initially folded into the body; the first higher-pitched ‘ring’ that you hear is the elbow opening and the second lower-pitched ring is the shoulder stretching up.

 

Though the accelerometer measurements were not mandatory to validate the deployment, the engineers working on Juice were happy to see that they are very accurate. Turning the vibration signal into sound may help us understand the mechanics of the deployment.

 

The boom is one of four 'Langmuir probes' that are part of Juice's Radio & Plasma Wave Investigation experiment. These probes will provide crucial information on the electric fields and plasma environment around Jupiter's moons.

 

The sonification was prepared by Johannes Z. D. Mieth (TU Braunschweig) and Willi Exner (ESA).

Chorus Radio Waves within Earth's Atmosphere

Voyager 1's plasma wave instrument detected the vibrations of dense interstellar plasma, or ionized gas, from October to November 2012 and April to May 2013. This sound reproduces the amplitude and frequency of the plasma waves as "heard" by Voyager 1.

Saturn is a source of intense radio emissions, which were monitored by our Cassini spacecraft. The radio waves are closely related to the auroras near the poles of the planet. These auroras are similar to Earth's northern and southern lights. This is an audio file of radio emissions from Saturn.

The Vela Pulsar data has also been converted to sound through a process called data sonification. In this sonification, listen to a radar-like scan, clockwise from 12:00 of the image. Brightness is mapped to volume. Distance from the center is mapped to pitch (farther away is higher pitch). For the Chandra X-ray data, the bright inner region (violet) is mapped to a low synth sound, with 11 Hz oscillations matching the period of the pulsar. The dimmer outer region (blue) and jet are mapped to a wind-like sound. A long upper jet can be heard around 4 seconds in, and a bright, but much shorter lower jet can be heard around 20 seconds. For the Hubble optical data, the stars are mapped to notes on a plucked-type synth (where brighter stars are louder, and stars farther from the center are higher pitched).

Chandra/Hubble Vela Pulsar Sonification

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.

History changed on 4 October 1957, when the Soviet Union successfully launched Sputnik I. The world's first artificial satellite was about the size of a beach ball (58 cm across), weighed only 83.6 kg and took about 98 minutes to orbit the Earth on its elliptical path. That launch ushered in new political, military, technological and scientific developments. While the Sputnik launch was a single event, it marked the start of the space age and the US-USSR space race.

Sputnik 1957 - history's first artificial signals from space

New research from the up-close Grand Finale orbits of NASA’s Cassini mission shows a surprisingly powerful interaction of plasma waves moving from Saturn to its moon Enceladus. Researchers converted the recording of plasma waves into a “whooshing” audio file that we can hear -- in the same way a radio translates electromagnetic waves into music. Much like air or water, plasma (the fourth state of matter) generates waves to carry energy. The recording was captured by the Radio Plasma Wave Science (RPWS) instrument Sept. 2, 2017, two weeks before Cassini was deliberately plunged into the atmosphere of Saturn.
