| Research Abstract |
High-velocity impacts of porous meteoroids on solid planetary surface are simulated in laboratory impact experiments at 6 km/s. The visible light intensity of impact flashes are measured, for the first time, for the impacts of porous meteoroids, though the material (Nylon66) for both the impactors and the targets are quite different from planetary materials. It has been revealed that the light energy for the porous impactors are about10times that for the solid impactors.
