Call from Mars

decide which sound we will broadcast from Mars to Earth

In March 2023 the first European planetary rover will land on Mars as part of the ExoMars mission. The rover's landing platform will carry 11 sound recordings (selected in this project) in the memory of a Czech scientific instrument. The sound recording that receives the most votes before the ExoMars probe lands on Mars will be transmitted back to Earth.

A cascade of tones fall from the top note of the piano to the bottom and rise back again, each mirroring the other. This whole tone melody passes once through what might be an endless spiralling 30 second cycle, each note of the piano's 88 sounded once. Two scales, gazing at each other across space and time. On the surface each pattern repeats in different depths of pitch, but their harmonic symmetries are dissolved in perception of the fleeting present moment.
