About a day ago we received last update from NASA’s Insight lander and it’s delivered a revelatory new message home: the sounds of Mars. InSight successfully touched down on the Martian surface on November 26, and has sent back several high-resolution images of its deserted environs. Now, for the first time in history, it’s sent back the eerie sound of the Martian winds. In a new video by NASA’s Jet Propulsion Laboratory, you can hear sounds and vibrations of Martian surface.
The recordings were made by InSight’s seismometer and air pressure sensor. At the time of the recording this whole video, the air pressure sensor logged a wind of 10-15 mph (15-24 km/h).
The seismometer will ultimately be used — once InSight finds a place for it on the Martian surface — to record the planet’s “pulse,” meaning the seismic sensations that might give researchers valuable evidences into what’s going on inside Mars. The air pressure device will assist the seismometer make sense of those measurements.
