Researchers have created the soundtrack of the 5000th March Sunrise captured by NASA’s robot Opportunity, using data-sonic techniques to create a two-minute music. Researchers from Anglia Ruskin University and University of Exeter in Britain created the piece of music by scanning a picture from left to right, pixel for pixels, looking at brightness and color information and combining them with terrain height.
They used algorithms to assign a specific pitch and melody to each element. The calm, slow harmonies are a consequence of the dark background and the lighter, higher pitches toward the center of the piece are created by sonication of the bright sunshine.
The piece of Sound Soundscapes will be presented at the Supercomputing SC1
8 Conference in Dallas, USA, November 13th. Researchers will use both conventional speakers and vibration sensors so the audience can feel the vibrations with their hands and thus enjoy a first person experience of a sunrise on Mars.
Opportunity is a robot robot that has provided photographic data on Mars for NASA since 2004. Earlier this year, communication ceased after a dust storm. Researchers hope it can resume its function later this year.
