A special phenomenon observed in hypervelocity impacts on rock targets is the so-called
momentum multiplication, ie the momentum transferred to the target is greater than the …

Understanding how to deflect an incoming asteroid is of great importance and a focus of
research undertaken internationally by the planetary defense community. Deflection of an …

Impact tests were performed from 4 to 5.77 km/s of 3.0-cm-diameter aluminum spheres
impacting 2024-T351 aluminum targets. This data was compared to previously published …

Utilizing a large two-stage light gas gun and a large pendulum assembly, experiments were
performed to measure the momentum enhancement (or increase in momentum transfer due …

Momentum enhancement refers to the effect of more momentum being transferred to a target
than resides in the impactor. This increased momentum transfer is due to crater ejecta …

Impact-cratering processes on small bodies are thought to be mainly controlled by the local
material strength because of their low surface gravity, and craters that are as large as the …

Hypervelocity tests with aluminum spheres of 1 and 1.75 inch (2.54 and 4.45 cm)-diameter
impacting pumice boulders at 2.1 km/s have been performed at Southwest Research …

In the previous symposium, it was demonstrated that extrapolation of momentum
enhancement β data from small laboratory tests to larger asteroid and comet nucleus …

Two NASA missions that will be launched in 2022 have spun renewed interest in
hypervelocity impact of rocks and metals. This paper is focused in the prediction of the …
