Initial results from the InSight mission on Mars. InSight auxiliary payload sensor suite (APSS). SEIS: InSight’s seismic experiment for internal structure of Mars. Distinct meteoroid families identified on the lunar seismograms. Meteoroid impacts as sources of seismicity on the Moon. Evidence for a meteoritic origin of the September 15, 2007, Carancas crater. The great Siberian meteor and the waves, seismic and aerial, which it produced. Statistical analysis of fireballs: seismic signature survey. Seismoacoustic coupling induced by the breakup of the 15 February 2013 Chelyabinsk meteor. Our findings demonstrate the capability of planetary seismology to identify impact-generated seismic sources and constrain both impact processes and planetary interiors. With identified seismic sources, the seismic waves can be used to constrain the structure of the Martian interior, corroborating previous crustal structure models, and constrain scaling relationships between the distance and amplitude of impact-generated seismic waves on Mars, supporting a link between the seismic moment of impacts and the vertical impactor momentum. Crater dimensions and estimates of meteoroid trajectories are consistent with waveform modelling of the recorded seismograms. We analysed arrival times and polarization of seismic and acoustic waves to estimate impact locations, which were subsequently confirmed by orbital imaging of the associated craters. Here we report observations of seismic and acoustic waves from the NASA InSight lander’s seismometer that we link to four meteoroid impact events on Mars observed in spacecraft imagery. However, new crater formation and the associated impact-induced mechanical waves have yet to be observed jointly beyond Earth. During atmospheric entry and impact on the ground, meteoroids excite transient acoustic and seismic waves. Meteoroid impacts shape planetary surfaces by forming new craters and alter atmospheric composition. Newly formed craters on Mars located using seismic and acoustic wave data from InSight
