A NASA lander on Mars has captured the vibrations and sounds of four meteoroids striking the planet's surface. Scientists reported Monday that Mars InSight detected seismic and acoustic waves from a series of impacts in 2020 and 2021. A satellite orbiting the red planet confirmed the impact locations, as far as 180 miles (290 kilometers) from the lander. Scientists are delighted by the detections — a first for another planet. The first confirmed meteoroid exploded into at least three pieces, each leaving its own crater. An 11-second audio snippet of this strike includes three “bloops,” as NASA calls them, one of sounding like metal flapping loudly in the wind here on Earth. “After three years of InSight waiting to detect an impact, those craters looke...
