New paper: Hypervelocity impacts in iron meteorites

PhD Candidate Soumya Ray is a co-author on a new research paper published in the Journal of Geophysical Research: Planets.

The paper, Hypervelocity impact experiments in iron-nickel ingots and iron meteorites: Implications for the NASA Psyche mission, details the results of a series of high-velocity impact experiments performed on iron meteorites and cast metal ingots with iron and nickel compositions similar to iron meteorites.

These results will be utilized to interpret the nature and history of asteroid Psyche when the ASU-led  NASA Psyche mission reaches its destination.

Psyche spacecraft
The mission plans launch in 2022 and arrival at Psyche, between the orbits of Mars and Jupiter, in 2026. This selected asteroid is made almost entirely of nickel-iron metal. It offers evidence about violent collisions that created Earth and other terrestrial planets.
