The speed of sound on Mars is different from Earth, Perseverance rover finds

NASA’s Mars rover Perseverance has found that sound travels much more slowly on the Red Planet than it does on Earth and behaves in some unexpected ways that could have strange consequences for communication on the planet.

Sound waves move more slowly through mars‘ atmosphere than they do on earth. This makes sense, as the speed of sound depends on the density of the material that the sound waves are traveling 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 moves at 4,856 feet per second (1,480 m/s), according to Science Alert.
