WebJan 17, 2024 · The work paid off, returning several unexpected findings. First, the team discovered that the rate of large crater formation on the Moon has been two to three times higher over approximately the last 290 million years than it had been over the previous 700 million years. The reason for this jump in the impact rate is unknown. WebApr 13, 2024 · April 13, 2024. Expanded craters on Mars are thought to occur when the upper slopes of an impact crater in an ice-rich target sublimate (going directly from a solid to a gaseous state). The vaporizing ice makes the walls retreat while the lower slopes are armored by dust and debris, resulting in a funnel-shaped formation.

WebThe lunar crater record features $\sim 50$ basins. The radiometric dating of Apollo samples indicates that the Imbrium basin formed relatively late -- from the planet formation perspective -- some $\simeq 3.9$ Ga. Here we develop a dynamical model for impactors in the inner solar system to provide context for the interpretation of the lunar crater record.
