NASA lander captures marsquakes, other Martian sounds
CAPE CANAVERAL, Fla. — NASA’s InSight lander on Mars has captured the low rumble of marsquakes and a symphony of otherworldly sounds.
InSight’s seismometer has detected more than 100 events, but only 21 are considered strong marsquake candidates. The rest could be marsquakes — or something else. 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.
InSight arrived at Mars last November and recorded its first seismic rumbling in April.
A German drilling instrument, meanwhile, has been inactive for months. Scientists are trying to salvage the experiment designed to measure the planet’s internal temperature.
