NASA lander captures marsquakes, other Martian sounds

NASA's InSight lander on Mars has captured the low rumble of marsquakes and a symphony of other otherworldly sounds. InSight's seismometer has detected more than 100 events, but only 21 are considered strong marsquake candidates. The French seismometer is so sensitive it can hear the Martian wind as well as movements by the lander's robot arm and other mechanical "dinks and donks " as the team calls them.
