NASA's Mars InSight landed over a week ago and is now recording sounds from space.
The sound we are hearing is from wind blowing against the Insight solar panels instruments.
Scientists estimate the winds to be blowing northwest to southeast at 10-15 miles per hour. This was a nice surprise to scientists who are dedicating part of the mission to measuring motion on Mars.
Two instruments helped detect this wind movement.
The first, an air pressure sensor. This is being used to collect meteorological data but it also recorded the air vibrations directly.
The second instrument is the seismometer, which might sound familiar to folks in California since it measures earthquakes. In this case, it recorded vibrations caused by the wind on Mars moving over the InSight's solar panels.
InSight landed on Mars ten days ago, on Nov. 26, 2018.
