Revealing spacecraft geometry effects on impact simulations for NASA’s DART mission

The same DART spacecraft impact can result in very different craters on Dimorphos depending on what the asteroid material is like. The crater on the left is the result if Dimorphos is composed of strong rocky material, while the much larger crater shown on the right could occur if the Dimorphos is made up of … Read more

When curved materials flatten, simple geometry can predict the wrinkle patterns that emerge

Nature Communications (2017). DOI: 10.1038/ncomms15809″ width=”800″ height=”530″/> Domain size scaling. Typical equilibrium wrinkle patterns in a hexagonal section of a thin spherical shell on a liquid substrate. All simulation parameters are kept fixed, except for the sheet thickness. The Föppl–von Kármán number γ of the system is indicated above each pattern. While the top-left pattern … Read more
