Correction to: Nature https://doi.org/10.1038/s41586-022-04679-0 Published online 1 April 2022 In the version of this article initially published, the Acknowledgements statement was missing the text “Part of this research was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration (80NM0018D0004),” which has now been inserted in the HTML and PDF versions of the article.
Abstract Prior to the Perseverance rover landing, the acoustic environment of Mars was unknown. Models predicted that: (i) atmospheric turbulence changes at centimeter scales or smaller at the point where molecular viscosity converts kinetic energy into heat1, (ii) the speed of sound varies at the surface with frequency2,3, and (iii) high frequency waves are strongly attenuated with distance in CO22–4.
