“…2 a, b ). This configuration is morphologically similar to many plains-filled craters in the equatorial regions of the Moon 23 , 24 , such as the mare-filled Colombo crater (~79 km diameter, centered at 15°S, 46°E; Fig. 2c ) and the light plain-filled Plummer crater (~73 km diameter, 25°S, 155°W; Fig.…”

Water ice and other volatiles that accumulated in the Moon’s polar regions are among the top priority targets for lunar exploration, due to their significances in both lunar geology and extraterrestrial resource utilization. Locating suitable landing sites and determining the provenance of sampled/measured surface materials are critical for future landed missions. Here, we map over 800 sites of plains terrains in the Moon’s south polar region, with a total surface area of ~46,000 km2. Orbital measurements and analog studies show that most of these plains have apparently higher albedo and lower iron content than volcanic mare plains, suggesting an origin of ejecta-induced debris flows from distant impact craters, especially from the Schrödinger basin. Our findings suggest that the entire lunar south polar region probably have experienced contributions from distant basin materials. We recommend these plains as priority landing sites for future exploration of lunar polar volatiles and early bombardment history.

“…Collisions between objects, such as those that occur in nuclear reactions and due to the generation of gravitational waves, widely occur in nature. Moreover, collisions between meteorites and planets are common in solar systems (Bierhaus et al, 2022;Mark et al, 2022;Kimi and Vijayan, 2023). Among the many previous celestial collision events, the Chicxulub impact event that occurred 66 million years ago has been widely studied (Alvarez et al, 1980;Goderis Steven et al, 2021;Ross et al, 2022;Nixon et al, 2022).…”

In recent years, seismic wave effects caused by meteorite impacts have been widely observed. The meteorite impact event that occurred 66 million years ago is one of the most famous impact events in Earth’s history. The influences of the seismic wave field generated by this collision event on the solid Earth itself is worth exploring. Therefore, this study initially estimated the seismic source parameter information based on the multiring structure of the meteorite crater, and then simulates the seismic event. The results of this study provide a possible explanation for the formation of the Earth’s tectonic plates. The findings of this study suggest that the seismic wave field generated by the meteorite impact event 66 million years ago may have caused the destruction of the Solid Earth, leading to the formation of the boundary between the Indian Ocean and the Pacific Plate. Simultaneously, this study has important significance for inspiring the development of new geoscientific methods.
