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.

About the project

Project suspended

The Council of the European Space Agency (ESA), in response to Russian aggression against Ukraine, decided on 17 March 2022 to suspend cooperation with Roskosmos. For this reason, the European-Russian ExoMars 2022 interplanetary spacecraft will not launch in September 2022.

What is ExoMars?

One of the main aims of the European Space Agency’s (ESA) interplanetary spacecraft ExoMars 2022 is to attempt to answer the question of whether there was ever life on Mars. The collaborating Russian space agency Roscosmos will provide the Proton-M launcher. It will bring a landing platform "Kazachok" with a European rover "Rosalind Franklin" to the surface of the planet, into the Oxia Planum region.

The robotic rover will carry a drilling set and a suite of scientific instruments designed for biological and geochemical research, while the instruments on board the landing platform will be dedicated to the investigation of its nearest environment. The launch of the ExoMars 2022 mission is planned for August-October 2022, with an anticipated landing on Mars in 2023.

Is there lightning on Mars?

One of the scientific systems carried on board the landing platform is the ’Martian ground electromagnetic tool’. The Czech Academy of Sciences’ Institute of Atmospheric Physics within its Department of Space Physics is preparing a wave analyser module for this system. The device will analyse fluctuations of the electromagnetic field measured in the range of audible frequencies. Using these measurements, we would like to find the answers to as yet unresolved questions: Are there electric discharges in the Martian dust clouds and dust devils? Can electromagnetic waves penetrate from outer space to the surface of the planet?

Picture of a dust devil on Mars obtained by a camera on board the Mars Reconnaissance Orbiter. The view covers an area of about 644 m across. The size of the shadow shows that the dust cloud reaches an altitude of over 800 m. It is approximately 30 m in diameter. Based on computer simulations and on an analogy with terrestrial volcanic lightning it is thought that hypothetical electric discharges might exist in similar formations. However, the existence of discharges on Mars has not as yet been confirmed. If successful, the European ExoMars mission would be the first to do so.
