Scientists translate sunrise images of Mars into music



Using photos of the 5,000th sunrise on Mars captured by the NASA rover Opportunity, British scientists have created two minutes of music.

The soundtrack is made by scanning images from left to right, pixel by pixel, and viewing brightness and color information and combining them with terrain elevation.

The team uses a technique called "data sonification" that spreads computer algorithms to determine each pitch element and certain melody to translate photos into music.

"We are really happy to present this work about a very interesting planet," said Domenico Vicinanza, Director of the Sound and Game Engineering (SAGE) research group at Anglia Ruskin.

"Image sonification is a very flexible technique for exploring science and can be used in several domains, from studying certain characteristics of the planet's surface and atmosphere, to analyzing weather changes or detecting volcanic eruptions," Vicinanza added.

Quiet and slow harmony is a consequence of a darker background and a brighter, higher-pitched sound towards the center of the piece created by the sonification of a bright sun disk.

Data sonification techniques can be applied in health sciences to provide scientists with new methods to analyze the occurrence of certain shapes and colors, which are very useful in diagnostic images, the team said.

Vicinanza together with Genevieve Williams from Exeter University,

will present a work titled Mars Soundscapes at NASA's booth at the upcoming SC18 Supercomputing Conference in Dallas.

This will be presented using conventional speakers and vibration transducers so that viewers can feel vibrations with their hands, so enjoy the first person experience of the sunrise on Mars.

Opportunity is a rover robot that has provided photographic data on Mars for NASA since 2004.

Earlier in 2018, communication stopped after a dust storm. Scientists hope to continue to function later this year.
