In the framework of this project, here we present all necessary methods to automatically identify these luminous events, their lunar impact coordinates, the origin of the impacting meteoroids, as well as the estimation of their physical properties such as mass and size. We tested our methods ...

“The study also found that large impact events on Earth such as the Chicxulub crater 66 million years ago could have been accompanied by a number of smaller impacts. If this is correct, it suggests that the age-frequency distributions of impacts on the Moon might provide valuable information ...
Luminous Efficiency of Hypervelocity Meteoroid Impacts on the Moon Derived from the 2015 Geminid Meteor Shower 来自 Semantic Scholar 喜欢 0 阅读量: 6 作者:D Moser,R Suggs,S Ehlert 摘要: Meteoroids cannot be observed directly because of their small size. In-situ measurements of the meteoroid ...
In a study published today inScience, the team shows the number of asteroid impacts on the Moon and Earth increased by two to three times starting around 290 million years ago. "Our research provides evidence for a dramatic change in the rate of asteroid impacts on both Earth and the Moon...

Laser altimetry data from NASA's Lunar Reconnaissance Orbiter have provided a comprehensive look at the cratering history of the inner solar system
THE most probable angle of a meteoroid impact on a planet is 45°, and an impact at 15° from the horizontal or lower is as likely as at 75° or higher 1,2 . Yet little direct evidence for oblique impacts exists on the Earth, for two reasons. Unless the
“We pinned them down on this hiatus… they were arguing that yes, there might have been a hiatus, but warming might be going into the ocean, or it could be due to volcanic activity. So we asked at what point would you begin to accept there had been no warming. If there is no war...
97% of the grains exhibit weak-to-no shock metamorphic features and no thermal overprints from shock-induced melting. By contrast, about 80% of the studied grains from bombarded crust on Earth and the Moon show such features. The giant impact proposed to have created Mars’ hemispheric ...
