The speed of sound on Mars is different from that of Earth, according to the Perseverance rover

NASA’s Mars Perseverance rover has discovered that sound travels much slower on the Red Planet than on Earth and behaves in unexpected ways that could have strange consequences for communication on the planet.

Sound waves travel slower through March‘atmosphere than they do on Earth. This makes sense, because the speed of sound depends on the density of the material the sound waves are passing through (and, additionally, on some other variables, including temperature). In earth’s atmosphereat 68 degrees Fahrenheit (20 degrees Celsius), sound travels at 1,125 feet (343 meters) per second, but in the much denser medium of water, it travels at 4,856 feet per second (1,480 m /s), according to Scientific alert.
