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.

Exit Empire created this song to celebrate science and space exploration. It was fascinating to play with the audio and include real sounds of Martian wind or first gravitational wave ever observed. There are also pictures of the landing location on Mars and the recently captured black hole converted to audio. Lyrics 'Light will come' refer to the Czech analyser with this song on board coming to Mars to study lightning. We also used typical Czech instruments cimbalom and organ. Keep looking up!

Baby Tom is laughing

I recorded my son, Tom, while he was laughing. I found it very funny, positive and inspiring :-))) It was in December 2018. Tom was 6 months old. My wife and I adopted Tom when he was 3 months old. He is a very joyful baby, often smiling and laughing :-) Why sending this sound to Mars: => It's positive, fun, quick and easy to understand. => Everyone made such a sound, so we can say it's universal. => In a way, I find that it's a good symbol for mankind.

Music from Earth, to Earth

I think that music is the highest possible form of art that can unite all the people. Everyone can understand music, without need for any translation. I combined instruments I collected from many different countries, to ideally represent everyone on Earth for this project. On a technical side, the song has a very short digital silence, to measure the signal to noise ratio, and concludes with ocean waves: life comes from water, and its white noise can be useful to understand data transmission.

This recording features the sound of wind, seagulls, a person playing their guitar, children playing and people talking. It's a slice of life on Earth and would bring sounds that will never be possible to a planet void of trees, humans and animals. I captured it on a sunny August day in 2016.
