Seismic constraints from a Mars impact experiment using InSight and Perseverance

Abstract NASA’s InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) mission has operated a sophisticated suite of seismology geophysics instruments on the surface Mars since its arrival in 2018. On 18 February 2021, we attempted to detect seismic acoustic waves produced by entry, descent landing Perseverance rover sensors onboard lander. Similar observations have been made Earth data from both crewed 1,2 uncrewed 3,4 spacecraft, Moon during Apollo era 5 , but never before or another planet. This was only event occur began operations that had an priori known independently constrained timing location. It therefore potential be used as calibration for other marsquakes recorded InSight. Here report no signal Perseverance’s is identifiable data. Nonetheless, measurements window enable us place constraints distance–amplitude relationships predict amplitude planetary impacts situ Martian impact efficiency (the fraction impactor kinetic energy converted into energy).
