Scientists Use , Meteoroid Shockwaves , to Locate New Craters on Mars.br Scientists have located new craters on br the surface of Mars using shockwaves br caused by meteoroids that struck the planet.br 'The Guardian' reports that the new craters will br help scientists build a more accurate picture br of the deep internal structure of the red planet. .br This is the first time we have felt br and heard an impact on another planet, Professor Raphael Garcia, Planetary seismologist br at the Higher Institute of Aeronautics and Space br at the University of Toulouse, via 'The Guardian'.br The seismic data recorded by Nasa’s br InSight lander included four impact events br that the researchers explored in detail.br The seismic data recorded by Nasa’s br InSight lander included four impact events br that the researchers explored in detail.br Signs of new craters were br then found using Nasa’s Mars br Reconnaissance Orbiter.br Photos taken before and after revealedbr new black patches on the ground, which br were used to pinpoint the impact sites.br One meteoroid crashed into Mars br on September 5, 2021, resulting br in three distinct shock waves. .br The first shockwave was created when br the space rock slammed into the Martian br atmosphere traveling at high speeds. .br The second occurred when the meteoroid br exploded just miles above the surface br of the planet, creating multiple fragments.br Those fragments then smashed br into the ground, creating br several fresh craters. .
