The piece of music is based on the data from NASA's Opportunity rover.

Researchers have produced the sound of Martian sunrise based on a photograph captured by NASA’s robotic rover Opportunity.

For the two-minute piece of music, researchers from Anglia Ruskin University and University of Exeter used image sonification – a technique for non-visual representation of a still image and scanned the photograph of 5,000th sunrise on Mars from left to right, pixel by pixel. By using algorithms, they looked at brightness, color and terrain elevation in the image and assigned each element a specific tone and melody, thus transforming the data into music.

The quiet, slow harmonies represent the dark background while higher pitched sounds are for brightness coming from the sun disk.

Music is a way to express action or movements that is missing in astronomical images. The new musical composition will be featured in the forthcoming Supercomputing SC18 Conference in Dallas (13 November).

“We are absolutely thrilled about presenting this work about such a fascinating planet,” said Dr. Vicinanza from Anglia Ruskin University.

“Image sonification is a really flexible technique to explore science and it can be used in several domains, from studying certain characteristics of planet surfaces and atmospheres, to analyzing weather changes and detecting volcanic eruptions. In health science, it can provide scientists with new methods to analyze the occurrence of certain shapes and colors, which is particularly useful in image diagnostics.”

NASA's solar-powered Opportunity rover captured the dawn of its 5,000th Martian day in February 2018. A Martian day or "sol" is about 40 minutes longer than a day on Earth and a Martian year lasts nearly two Earth years.

Opportunity arrived at Mars in January 2004. The mission was originally planned for 90 sols but it exceeded all the expectations and went well beyond its expected lifetime.

Opportunity rover worked actively until 2018 when a massive dust storm swept over Mars and forced the rover to suspend science observations. Opportunity’s last contact with Earth was June 10. Researchers hope that it may resume its function later this year.
