It may be best heard with headphones..
The video was shared by NASA and, according to the space agency, captures the sound of a northwest Martian wind blowing at 10 to 15 mph..
"Capturing this audio was an unplanned treat," said Bruce Banerdt, InSight principal investigator at NASA's Jet Propulsion Laboratory (JPL) in a statement. "But one of the things our mission is dedicated to is measuring motion on Mars, and naturally that includes motion caused by sound waves."
NASA explained that the audio is wind vibrations picked up by two sensors on the lander and not an actual recording from a microphone. However, the Mars rover that will be launched in 2020 will have microphones aboard.
