NASA reported that the winds were likely blowing from the northwest in the direction of the southeast, the way the streaks in the landing area seem to move as well.
SOUNDS OF THE REALLY UNWORLDLY MARTIAN WIND
The wind is estimated to be blowing 16 kph to 24 kph. These are the first sounds from Mars that are detectable by human ears, according to the researchers.
"Capturing this audio was an unplanned treat," Bruce Banerdt, InSight principal investigator at NASA's Jet Propulsion Laboratory in Pasadena, Calif., said 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."
