Jan 1, 2011 · Ejecta were collected in bins at various distances from the impact. The observed nearly-90° ejection angle and the fall-distance to the chamber floor were used to calculate the …

The initial particle creation can result from a variety of processes. When volcanic ejecta form, the primary breakup mechanism is the result of a violent dissolution of gases as the geological …

Mar 1, 2022 · The amount by which crater ejecta enhances asteroid deflection—that is, the momentum of the crater ejecta that escapes the gravitational attraction of the target body …

Mar 1, 2019 · As an example, Fig. 3 shows the ejecta velocity histogram with cumulative size distribution for a Cu projectile impacting on a sandstone target. A luminescent transient …

The rock avalanche/ ejecta (RAEJ) documented by Crosta et al. (2018a, b) represent peculiar types of landslides that can be found on Mars but are unknown on Earth (Fig. 14). These …

Sep 15, 2021 · Continuous ejecta deposits around Martian layered ejecta craters larger than about a kilometer in diameter typically exhibit features such as lobate outlines, and extensive …

Sep 1, 2024 · Impact cratering is an important geological process on Earth. This review summarizes the state of knowledge of the Precambrian (Hadean, Archean, and P…

The size of ejecta that penetrated the foil targets at a velocity lower than the assumed values would have been underestimated, as the ratio of the hole size to ejecta size increases with …

May 1, 2014 · Martian impact craters often exhibit unique ejecta morphologies relative to ballistically-dominated ejecta observed in lunar and mercurian impact craters (Carr et al., …

Therefore, the forward ejecta ratio varies across different materials and impact conditions, making it an effective metric for evaluating forward ejecta. Table 6 presents the mass of the recovered …
