NASA’s InSight lander ’hears’ wind on Mars 美國航太總署（NASA）的洞察號登陸器「聽見」火星風聲
Humans can now hear the low rumble of wind on Mars for the first time, after NASA’s InSight lander captured vibrations from the wind on the Red Planet.
The strong gusts of wind, blowing between 10 to 15 mph, were captured as they moved over the solar panels on InSight, an unmanned lander that touched down on Earth’s desolate neighbor November 26.
Two sensors picked up the vibrations: an air pressure sensor inside the lander and a seismometer on the lander’s deck, awaiting to be deployed to the surface by InSight’s robotic arm.
"This is the very first fifteen minutes of data that have come from the short period seismometer," said Thomas Pike, lead investigator at Imperial College London. "It’s a little like a flag waving in the wind," he added. "It really sounds otherworldly, and that is exactly what it is."
Sensing the wind, which moved from northwest to southeast at around 5 pm local time, was "an unplanned treat," said Bruce Banerdt, InSight principal investigator at NASA’s Jet Propulsion Laboratory.
