December 17, 2018 | Motion Control InSight Measures Motion on Mars In the foreground, a copper-colored hexagonal cover protects the Seismic Experiment for Interior Structure instrument (SEIS), a seismometer that will measure marsquakes. (NASA/JPL-Caltech) NASA’s InSight lander has provided the first ever "sounds" of Martian winds on the Red Planet. Sensors captured a haunting low rumble caused by vibrations from the wind, estimated to be blowing between 10 to 15 mph. When earthquakes occur on Earth, their vibrations, which bounce around inside our planet, make it "ring" similar to how a bell creates sound. InSight will see if tremors, or marsquakes, have a similar effect on Mars. Source View the discussion thread.
