One year later, painstaking analysis of all these recordings have allowed researchers to determine the speed of sound on Mars. Unlike on Earth, there are two speeds of sound on Mars, one for low frequencies and one for high-pitched sounds. Since arriving on Mars in February 2021, Perseverance has managed to capture more than five hours of recordings of the red planet’s sound environment. One sound that can be clearly distinguished is that of the wind. One of the major observations made from l…
