InSite Heard Four Meteoroids Crash Into Mars By Nancy_A
“After three years of InSight waiting to detect an impact, those craters looked beautiful,” said Ingrid Daubar of Brown University, a co-author of a paper detailing the findings, published in Nature Geoscience.
“We’re learning more about the impact process itself,” Garcia said. “We can match different sizes of craters to specific seismic and acoustic waves now.”Scientists said the four meteoroid impacts confirmed so far produced small quakes with a magnitude of no more than 2.0.
Knowing about the rate of impacts is important because that helps planetary scientists estimate the age of a planet’s surface. InSight captured this image of one of its dust-covered solar panels on April 24, 2022, the 1,211th Martian day, or sol, of the mission. Credits: NASA/JPL-Caltech
