InSight landed on the equatorial plains of Mars in 2018 and has since recorded more than 1,300 marsquakes.<\/p>\n<p>&#8220;It&#8217;s going to be heartbreaking when we finally lose communication with InSight,&#8221; said Bruce Banerdt of NASA&#8217;s Jet Propulsion Laboratory, the lander&#8217;s chief scientist who took part in the studies. &#8220;But the data it has sent us will certainly keep us busy for years to come.&#8221;<\/p>\n<p>Banerdt estimated the lander had between four to eight more weeks before power runs out.<\/p>\n<p>The incoming space rocks were between 16 feet and 40 feet (5 meters and 12 meters) in diameter, said Posiolova. The impacts registered about magnitude 4.<\/p>\n<p>The larger of the two struck last December some 2,200 miles (3,500 kilometers) from InSight, creating a crater roughly 70 feet (21 meters) deep. The orbiter&#8217;s cameras showed debris hurled up to 25 miles (40 kilometers) from the impact, as well as white patches of ice around the crater, the most frozen water observed at such low latitudes, Posiolova said.<\/p>\n<p>Posiolova spotted the crater earlier this year after taking extra pictures of the region from orbit. The crater was missing from earlier photos, and after poring through the archives, she pinpointed the impact to late December. She remembered a large seismic event recorded by InSight around that time and with help from that team, matched the fresh hole to what was undoubtedly a meteoroid strike. The blast wave was clearly visible.<\/p>\n<p>Scientists also learned the lander and orbiter teamed up for an earlier meteoroid strike, more than double the distance of the December one and slightly smaller.<\/p>\n<p>&#8220;Everybody was just shocked and amazed. Another one? Yep,&#8221; she recalled.<\/p>\n<p>The seismic readings from the two impacts indicate a denser Martian crust beyond InSight&#8217;s location.<\/p>\n<p>&#8220;We still have a long way to go to understanding the interior structure and dynamics of Mars, which remain largely enigmatic,&#8221; said Doyeon Kim of ETH Zurich&#8217;s Institute of Geophysics in Switzerland, who was part of the research.<\/p>\n<p>Outside scientists said future landers from Europe and China will carry even more advanced seismometers.
