A team of scientists from the Anglia Ruskin University and the University of Exeter in the UK applied data sonification techniques to a photo of the 5,000th Mars sunrise captured by the NASA rover Opportunity, to create a two-minute piece of music.Researchers created the piece of music by scanning a picture — captured by the  solar-powered, robotic exploration rover, Opportunity, in early 2018 — from left to right, pixel by pixel, and looking at brightness and color information and combining them with terrain elevation, according to a press release by the Anglia Ruskin University.The researchers used algorithms to assign each element a specific pitch and melody.The resulting song, titled “Mars Soundscapes” and released this week, sounds soothing yet (unsurprisingly) otherworldly.“The quiet, slow harmonies are a consequence of the dark background and the brighter, higher pitched sounds towards the middle of the piece are created by the sonification of the bright sun disk,” according to Anglia Ruskin University.The world premiere of the piece will be presented at the Supercomputing SC18 Conference in Dallas, Texas,  on November 13. Presenters Dr. Domenico Vicinanza, of Anglia Ruskin University, and Dr. Genevieve Williams, of the University of Exeter, will use both conventional speakers and vibrational transducers “so the audience could feel the vibrations with their hands, thus enjoying a first-person experience of a sunrise on Mars.”“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 analysing weather changes or detecting volcanic eruptions,” says Dr. Vicinanza, who is director of the Sound and Game Engineering (SAGE) research group at Anglia Ruskin.“We are absolutely thrilled about presenting this work about such a fascinating planet,” he said.More on Geek.com:SpaceX Rehearses Recovery of Astronauts During Ocean LandingsNASA Releases First 8K Video From Space (And It’s Really Cool)NASA to Play Classic Arcade ‘Claw Game’ on Marslast_img read more
