Sounds of Mars: Hello from the children of planet Earth

NASA attached golden records to each of the twin Voyager spacecraft before they launched in 1977. The purpose was to send a message from Earth to any spacefarers that might find the spacecraft in the future. In addition to images, music, and sounds from Earth, greetings in 55 languages were aboard, including this one in English.

This audio clip has been adjusted to simulate what it might sound like in the atmosphere of Mars. Scientists on the Perseverance rover team took into account the three key variables of atmospheric temperature, density and chemistry to generate this Mars version.
