How they figured this out is mind-blowing 🤯
that can trigger a perfectly timed noise. Using the microphone, they were able to study the properties of sound around the rover's vicinity, allowing them to confirm predictions made using the information we know about Mars' atmosphere. They showed definitively that the speed of sound near the surface of Mars is approximately 240 meters per second.As the popular misconception goes, no one can hear you scream in space.
Though future Mars astronauts would communicate with each other in pressurized, oxygenated habitats, it's interesting to think about the wild implications of this sound perception if two humans were able to communicate out in the open on Mars. "Due to the unique properties of the carbon dioxide molecules at low pressure, Mars is the only terrestrial-planet atmosphere in the Solar System experiencing a change in speed of sound right in the middle of the audible bandwidth "They added that this could lead to a"unique listening experience" on Mars. Hypothetically speaking, it might let people with higher-pitched voices communicate faster than those with lower voices.
