Abstract
We congratulate the Perseverance rover team for measuring a dust devil and other sounds on Mars. This is a great achievement, and at the same time just a beginning. The acoustics community needs to apply itself to the situations that might come up when humans visit Mars. Work in the late 1990s and early 2000s set the stage for our knowledge of the outdoor sound environment of Mars. One next step will be to understand how shock waves and sonic booms will propagate on Mars. Because of the high atmospheric absorption, the shock structures of sonic booms are expected to differ on Mars compared to those on Earth. Some of the differences in potentially using a program like NASA’s PCBoom suite of tools will be discussed. Sonic booms have been used in the past to probe the atmosphere on Earth, and the prospects seem bright for successful similar applications on Mars.
