Mars experiences between 180 and 360 significant impacts per year, according to recent NASA InSight mission data.
Seismic shockwaves generated by these impacts are crucial for assessing potential hazards for future exploration missions on Mars.

Mars, the fourth planet from the Sun, has long been known to experience meteorite impacts. However, recent data from NASA's InSight mission has revealed that the Red Planet may be experiencing these impacts at a much higher rate than previously estimated. According to multiple studies based on seismic data collected by InSight's seismometer, Mars experiences between 180 and 360 significant impacts per year, with some sources suggesting rates as high as two to ten times the previous estimates.
These impacts can range in size from basketball-sized objects to much larger ones. For instance, two significant impacts were detected only 97 days apart, which is unusual and may suggest a higher impact rate on Mars. The seismic shockwaves generated by these impacts are crucial for assessing potential hazards for future exploration missions as NASA sends rovers or even human missions to Mars.
The Valles Marineris canyon system on Mars, one of the largest and most famous geological features in the Solar System, is a testament to the planet's history of meteorite impacts. This vast canyon system stretches over 2,500 miles (4,027 kilometers) long and reaches depths up to 6 miles (10 kilometers).
The new findings about Mars' impact rate challenge our understanding of the planet's geological history and evolution. Researchers are now working to better understand the implications of these discoveries for Mars and other planets in our Solar System.
Mars experiences almost daily impacts from rocks the size of a basketball slamming into its surface.

Fallacies
(95%)
The author makes several statements that are supported by evidence and do not contain any identified fallacies. However, there is one instance of an appeal to authority when the authors state that 'seismology is an excellent tool for measuring impact rates.' This statement does not detract significantly from the overall quality of the article and does not warrant a significant reduction in score.
